Industrial Strength Savings: Where to Buy Second Hand Dishwashers

The Smart Restaurateur's Secret: Why Used Dishwashers are a Winning Investment

Second hand commercial dishwashers for sale offer restaurant owners a powerful way to cut costs without sacrificing quality. For savvy operators, buying used isn't just about saving money; it's about making a strategic business decision that preserves capital for other critical needs like marketing, staffing, or menu development. With thoughtful selection, a pre-owned unit can perform on par with a new machine, while freeing up thousands of dollars for growth activities that customers can actually see and feel.

Immediate availability is another advantage. New models can be backordered or delayed during peak seasons, but high-quality used units are often ready to ship. That means you can open sooner, recover from a breakdown faster, or keep pace with a sudden surge in demand without missing service.

Here's what you need to know about the used market:

• Top Sources: Specialized used dishwasher dealers, online supply stores, and refurbished unit suppliers offer the best balance of cost savings and reliability. Look for sellers who disclose serial numbers, service histories, and test results, and who offer post-sale support.
• Price Range: Used commercial dishwashers typically cost 30-60% less than new models, with prices ranging from $500 to $3,500 depending on the unit's type and condition. Refurbished units with a short warranty often sit toward the top of that range, trading a small premium for peace of mind.
• Most Reliable Brands: The most reputable brands dominate the second-hand market due to their proven durability and wide parts availability. These brands are known to run for years with routine maintenance and readily sourced components.

The used commercial dishwasher market is growing as more foodservice operators recognize the financial and environmental benefits. You can find quality undercounter models, door-type units, and even high-capacity conveyor systems at a fraction of their original cost. When you purchase a refurbished unit from a reputable dealer, you're getting a machine that's been professionally tested and serviced—often with warranty protection that provides essential peace of mind.

According to the EPA's Food Recovery Hierarchy, extending the life of existing appliances through reuse is a key sustainability practice that reduces environmental impact. This principle applies directly to commercial dishwashers, where buying used keeps functional machines out of landfills while conserving the resources needed to manufacture new units.

The key is knowing what to look for, where to buy, and how to assess a unit's condition before you commit. In the sections below, we'll break down the business case, types of machines, evaluation criteria, and buying strategies, so you can make a confident, cost-effective decision that keeps dishes moving and margins healthy.

The Unbeatable Benefits of Buying a Used Commercial Dishwasher

Smart operators know that a quality second hand commercial dishwasher for sale can deliver the same sparkling clean dishes as a brand-new model, but at a fraction of the cost. When every dollar matters, the money saved on your warewashing machine can be redirected to what truly drives your business forward—hiring talented staff, perfecting your menu, or creating a memorable dining experience.

The savings are substantial. Purchasing a used commercial dishwasher typically results in savings of 30-60% compared to buying new. For a door-type dishwasher that might cost $8,000 new, you could find a quality used model for $3,000 to $5,000. This isn't small change; it's thousands of dollars that stay in your pocket. This upfront saving preserves capital that can work harder elsewhere in your business, giving you flexibility and breathing room. A used unit also delivers a faster return on investment. Since your initial outlay is smaller, the machine pays for itself much quicker. Furthermore, a used unit has already taken its biggest depreciation hit, meaning you experience lower depreciation and can maximize its value if you decide to sell it later.

Beyond the price tag, choosing a pre-owned dishwasher is an eco-friendly choice. You're participating in the circular economy, extending the life of a functional machine and reducing landfill waste. Manufacturing a new dishwasher generates a substantial carbon footprint; by buying used, you eliminate that impact. This commitment to sustainability resonates with customers and employees, strengthening your brand's reputation.

The used market also provides access to premium brands that might otherwise be out of reach. These machines are built to withstand the rigors of a high-volume kitchen for years. When you find one on the second-hand market, you're getting proven reliability and performance at a price that makes sense. These are workhorses that have already demonstrated they can handle real-world demands. For more insights, check out our guide on Used Commercial Dishwashing Machines.

The Financial Advantage

• Upfront savings and capital preservation: Redirect funds from your dishwasher purchase into revenue-generating initiatives like staff training, marketing campaigns, delivery partnerships, or menu development.
• Faster ROI: Because your initial investment is smaller, the breakeven point arrives much sooner. For example, if a used door-type unit costs $4,000 and supports $200 in revenue per service from table turns and reduced labor bottlenecks, it can pay for itself in weeks rather than months.
• Lower depreciation: New machines take the steepest depreciation hit in the first 12–24 months. When you buy used, much of that loss is already absorbed, and the resale value relative to your cost can be favorable if you upgrade later.
• Predictable total cost of ownership: A refurbished unit from a reputable dealer typically arrives with fresh gaskets, descaled components, and tested pumps, reducing surprise repairs in the first year.

The Sustainability Factor

• Circular economy and waste reduction: Keeping robust machines in use reduces landfill contributions and conserves the energy required to manufacture new models.
• Lower carbon footprint: Avoid the embedded emissions associated with new production. For brands known for long service lives, reusing one high-quality dishwasher can have a meaningful environmental impact over a decade or more.
• Resource conservation: Water and energy improvements aren’t limited to new models. Many modern used dishwashers were ENERGY STAR-qualified when new, meaning you can secure efficiency at a lower cost.
• Customer and team alignment: Sustainability practices are increasingly important to both diners and employees; buying used is a simple, visible step that supports broader ESG goals.

A Guide to the Types of Used Commercial Dishwashers

When shopping for second hand commercial dishwashers for sale, you'll find the same variety as new models, but at a much lower price point. Each type is designed for specific kitchen layouts and volumes, so understanding the differences is key to making the right choice. You'll also encounter both high-temperature models, which use hot water to sanitize, and low-temperature models, which use chemical sanitizers. The key is to match the machine's capabilities to your dishwashing volume and space constraints. For a comprehensive look at how these different types fit into various restaurant operations, our Commercial Dishwasher Restaurant Guide offers detailed insights.

Undercounter Dishwashers

Perfect for operations with limited space, undercounter dishwashers are compact but powerful. They slide neatly beneath a standard counter, making them ideal for small restaurants, bars, and coffee shops. Despite their size, these machines are fast, with wash cycles of just 2 to 4 minutes. With a typical capacity of 20 to 40 racks per hour, they can easily keep up with the demands of a smaller establishment. If you're considering if this model is right for you, our Under Counter Dish Washer guide provides more detail.

Use undercounters when:

• Your footprint is tight and you need to leverage under-bar or back-of-house space.
• You want quick cycle times for glassware and small-ware.
• Your peak rack demand stays below roughly 40 per hour.

Door-Type / Pass-Through Dishwashers

Door-type dishwashers are the workhorses of medium-sized operations, handling 30 to 80 racks per hour. Their pass-through design creates an ergonomic workflow: a rack of dirty dishes slides in from one side, and clean dishes emerge from the other. This setup, often complemented by dish tables for sorting and drying, minimizes strain and maximizes productivity. The fast cycle times ensure a steady supply of clean dishes during peak hours, making this a popular choice for busy restaurants that need a balance of capacity and efficiency.

Choose a door-type when:

• You need higher throughput than an undercounter can deliver but don’t require a conveyor.
• You want a flexible layout with scrap, wash, and clean tables to streamline flow.
• You have staffing to manage racks efficiently through lunch and dinner rushes.

Conveyor Dishwashers

For high-volume establishments like large restaurants, cafeterias, and hospitals, conveyor dishwashers are the ultimate solution. These heavy-duty machines are built for continuous washing and maximum throughput. Instead of manually loading racks, a conveyor system automatically pulls dishes through multiple washing and rinsing zones. This automation eliminates bottlenecks and ensures a constant flow of clean ware. Available in both rack and rackless models, a used conveyor dishwasher delivers industrial-strength washing power at a significantly reduced cost. Contact us to discuss if a conveyor system is the right fit for your volume.

Consider a conveyor when:

• Your peak demand consistently exceeds 100 racks per hour.
• You want to minimize labor touchpoints and keep a constant flow.
• You have the utilities, space, and staff to support loading/unloading zones.

Glasswashers

Glasswashers are specialized undercounter units tuned for bars and tasting rooms where spotless, lipstick-free glassware matters. They feature custom racks, gentle cycles, and specific spray patterns designed to protect delicate stems while ensuring clarity that showcases beverages. A used glasswasher can be a targeted, affordable upgrade for bar programs that struggle with haze or residue on glassware.

Pot and Pan Washers

These machines handle bulky cookware, sheet pans, and utensils that overwhelm standard racks. They typically provide larger chambers, stronger pumps, and robust wash arms to remove baked-on residues. If your operation produces a high volume of cookware, buying a used pot and pan washer can offload tedious scrubbing, rebalancing labor toward prep and service.

High-Temp vs. Low-Temp: Which Should You Choose?

• High-Temp Models: Use very hot water for sanitization, often with a booster heater. They avoid chemical sanitizers on the final rinse, which some operations prefer for taste/smell reasons. They may have higher energy draw but can simplify chemical management.
• Low-Temp Models: Use chemical sanitizers (like chlorine-based solutions) at lower rinse temperatures. They typically draw less energy but require ongoing chemical purchases and careful monitoring of concentrations.

Not sure which route to take? Consider your utility costs, chemical budgets, health department requirements, and staff training. If you want help matching a machine to your menu, volume, and floor plan, contact us for custom guidance.

Key Factors When Searching for Second Hand Commercial Dishwashers for Sale

Finding the right second hand commercial dishwashers for sale requires looking beyond the price tag. A smart purchase balances condition, brand reputation, and features to ensure long-term value. A well-maintained machine from a trusted brand will serve your kitchen far better than the cheapest option with a questionable history. Before you commit, we recommend reading our Buy Commercial Dishwashers Guide for detailed advice.

How to Assess the Condition and Remaining Lifespan

Think of yourself as a detective when inspecting a used dishwasher. A thorough evaluation can reveal its true condition and help you estimate its remaining lifespan. Here's a checklist:

• Visual Inspection: Check the exterior and interior for rust, corrosion, warping, and excessive dents. Pay close attention to seams and the bottom of the unit, as rust can indicate past leaks. Inspect the sump and tank corners, where standing water can accelerate corrosion.
• Internal Components: Examine the wash arms for cracks, wobble, or blocked nozzles. Look at heating elements and booster heaters for heavy scale buildup, which suggests hard water issues and poor maintenance. Confirm that spray jets are present and not mismatched.
• Seals and Gaskets: Ensure all door seals are supple and intact. Dried-out or cracked gaskets are a primary cause of leaks. Check inspection ports, curtains (on conveyors), and any sight glass features.
• Pumps and Motors: Run a test cycle if possible. Listen for unusual grinding or rattling from pumps, motors, and conveyors. Watch water pressure, verify even spray patterns, and confirm thorough draining.
• Controls and Safety Features: Verify that control panels, thermostats/thermistors, and interlocks operate as intended. Confirm that over-temp protections and door switches function properly.
• Utilities and Installation: Confirm electrical phase/voltage, water inlet size/pressure, and drain requirements match your site. Inspect cords, junction boxes, and plumbing for wear or unsafe modifications.
• Ask for Service Records: A documented maintenance history is a strong indicator of a well-cared-for machine. A lack of records should be a red flag. Prioritize units that have been descaled, had regular deliming, and received scheduled gasket replacements.

A refurbished unit from a reputable dealer like The Restaurant Warehouse has already undergone professional inspection and servicing, which significantly reduces your risk. For more tips, see our Restaurant Dishwasher Guide.

Top Brands to Look For in the Second-Hand Market

In the used market, brand reputation is a reliable predictor of durability. Look for manufacturers with a legacy of robust construction and consistent performance. Top-tier brands are respected for workhorse dependability and are popular because they are built to last, and parts and service are widely available, making them a safer investment.

Energy and Water Efficiency Considerations

The purchase price is only one part of the cost. Monthly utility bills are a major factor in the total cost of ownership. When evaluating a used machine, consider its water consumption per rack and energy draw in real-world conditions.

• Water Use: High-efficiency models often use significantly less water per rack than older units—savings that add up to thousands of gallons per year. Compare the unit's spec sheet against your operating hours and rack counts to estimate annual water savings.
• Energy Use: High-temp machines require energy to heat rinse water, while low-temp models rely on sanitizers. Either can be efficient if sized and maintained properly. Insulation, heat recovery, and idle modes also influence energy use.
• Chemicals and Scale: If you choose a low-temp unit, budget for chemical concentrates and test kits. For any machine, hard water increases scale and hurts efficiency; factor in deliming cycles and water treatment.

Not sure how to benchmark a candidate machine? Start with certified performance criteria. The ENERGY STAR program for commercial dishwashers provides baseline water-per-rack and energy-per-rack targets, then compare your used unit's data plate or manual to those standards. Even if an older model isn't certified, this gives you a practical yardstick for total cost of ownership.

Practical Sizing and Layout Tips

• Throughput: Estimate peak racks per hour during lunch/dinner rushes and choose a machine with 10-20% headroom.
• Workflow: Plan dirty-to-clean flow using scrap tables, pre-rinse locations, and adequate landing space for drying. Avoid cross-traffic with prep lines.
• Heat and Moisture: Ensure adequate ventilation and drainage to keep floors dry and prevent steam from creating uncomfortable work environments.
• Accessibility: Leave service clearances for technicians; crowded installs increase maintenance time and cost.
• Future Growth: If you plan to expand seating or add catering, consider machines that can scale—either by throughput or by adding a second unit.

Navigating the Risks: How to Buy Safely and Avoid Pitfalls

Buying second hand commercial dishwashers for sale involves some risk. A used dishwasher has a history of wear and tear, and warranties are often limited or non-existent. However, these risks are manageable with a smart and cautious approach. The secret is knowing where to buy, what to look for, and how to protect yourself. By doing your homework, you can find a reliable machine that offers incredible value.

For practical tips on keeping any warewashing machine running smoothly, our Washing Machine for Dishes Guide offers insights that apply to both new and used machines.

Understanding Warranties and Maintenance

The biggest concern for most buyers is the warranty. While an "as-is" purchase from a private seller comes with no guarantees, many reputable dealers who sell refurbished units offer their own protection. A typical 3 to 6-month parts and labor warranty is a strong sign that the seller stands behind their product. It means the machine has been professionally inspected, serviced, and tested. This warranty transforms a potential gamble into a calculated, low-risk investment.

Beyond the warranty, consider the availability of spare parts. Sticking with well-known, reputable brands is a practical choice because their parts are easy to source, minimizing potential downtime. We also recommend having a professional technician inspect any machine before you buy it from a private party or auction. The cost of an inspection is small compared to the potential cost of unforeseen repairs.

Create a maintenance plan before the machine arrives:

• Set deliming schedules based on water hardness and usage.
• Stock critical spares (gaskets, curtains, filters, jets) to avoid emergency downtime.
• Train staff on loading best practices, chemical checks (for low-temp), and basic troubleshooting.
• Schedule a post-installation check after the first week of operation to catch leaks, loose fittings, or incorrect settings early.

Finding Reputable Sources for Second Hand Commercial Dishwashers for Sale

Where you buy your used dishwasher is as important as what you buy. Prioritize sources that offer transparency, support, and quality assurance.

• Specialized Used Dishwasher Suppliers: These businesses build their reputations on selling reliable, inspected dishwashers. They have the expertise to vet machines properly and often provide warranties.
• Online Restaurant Supply Stores: Retailers like The Restaurant Warehouse curate their used inventory, offering detailed descriptions, customer support, and greater accountability than a private seller.
• Refurbished Unit Dealers: These specialists restore used machines to excellent working condition, replacing worn parts and conducting thorough testing. The premium you pay for a refurbished unit buys you peace of mind and reliability.
• Auctions and Private Sellers: These sources can offer the lowest prices but carry the highest risk. Dishwashers are almost always sold "as-is" with no warranty. This route is best for experienced buyers who can inspect the unit thoroughly and are prepared to handle any necessary repairs.

Always prioritize a dealer's reputation, customer reviews, and after-sales support over the lowest price. A trustworthy source can save you money and headaches in the long run. If you're ready to explore quality used dishwashers, reach out to us—we're here to help you make the right choice.

Receiving, Installation, and Risk Mitigation Checklist

• Delivery Readiness: Confirm door widths, pathway clearances, and water/electrical shutoffs are accessible before delivery day.
• Damage Inspection: Inspect freight immediately upon arrival. Note any visible damage on the bill of lading and take photos before signing.
• Utilities Match: Verify voltage/phase, water pressure/temperature, and drain configurations. Mismatches can cause immediate failures or safety hazards.
• Commissioning: Run test cycles with a technician present, confirming proper fill levels, temperatures (for high-temp), chemical concentrations (for low-temp), and leak-free operation.
• Documentation: File manuals, wiring diagrams, and service records in a single location; label the unit with water hardness and deliming schedule.
