How to use WashyDish

In the search field, describe what you need in one sentence. An AI model turns your sentence into the comparison's filters. You see those filters and can remove any of them. The AI writes no answer; it only handles searches about the product.

Examples of sentences the existing filters can handle:

• “A quiet dishwasher for a small kitchen.”
• “An ENERGY STAR model that uses little water.”
• “A compact dishwasher for a countertop.”
• “A standard model with room for a large household.”
• “A dishwasher that fits under my counter.”

If a sentence points to something the filters do not cover, remove the filters you do not want and continue with the list.

The quiz has 4 questions. The models that match at least half of your answers are kept and ranked from best to least match. Use it when you have no precise sentence in mind and want a shorter list to start from.

Every filter has a “?” that explains what it does. Open it before you use the filter if the label is not clear. The filters and the sort are written into the page address, so you can share the exact view with someone else by copying the address.

The sort works together with the filters and is also written into the page address. A shared address therefore opens the same filtered and sorted list for the person you send it to.

Put up to 4 models side by side. The best figure in each row is highlighted. The comparison can be shared with a link, so the other person sees the same models and the same highlighted rows.

Every product card has a heart. The list of favorites stays in your browser; we never receive it. Use it to keep a few models at hand while you move between filters and the comparison.

Open a model to see its detail panel. It shows the price with the date it was collected, and a model without a price is out of stock. Prices come from the product pages on Amazon.com and are updated every 7 days.

Where official data exists, the panel shows the certified annual energy use in kWh, the water used per cycle in gallons, the number of place settings and the product class (standard or compact). For ENERGY STAR models it also shows the certification, the percentage below the federal minimum and the official width and depth. This data comes from the U.S. Department of Energy's Compliance Certification Database and ENERGY STAR (U.S. EPA); the database is at regulations.doe.gov/certification-data.

Where no register lists a model, the panel shows what the Amazon.com listing gives, marked as such. No U.S. register gives an energy class or a noise level.

The panel also shows the cost over 10 years: today's purchase price plus annual energy use times $0.1816 per kWh times 10, at a constant rate. The tariff comes from the U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.A (average residential price, U.S. total, August 2026).

To check whether a model fits, enter the height, width and depth available in inches. The site keeps the models whose dimensions fit inside and shows the margin left. The dimensions are the official width and depth for ENERGY STAR models and the ones on the Amazon.com listing otherwise. The clearance needed for the door, the hoses and the power cord is given in each model's manual.

A model can carry at most one badge, computed within its category: most popular (most customer reviews) or top rated (best rating among the models with at least 100 customer reviews). Hover over the badge to see the rule.

Links to Amazon are affiliate links: we earn a commission on a purchase, at no extra cost to you. No manufacturer pays to be listed or ranked higher. A model enters the comparison when it reaches the minimum rating of 3.5/5 and the minimum of 5 customer reviews on Amazon; stock is not a criterion.
