Appliance Diagnostic Tool

Pick your appliance and what it is doing. The questions change based on your answers, and the result ranks the likely causes rather than guessing at one.

Step 1 of 3

What are you troubleshooting?

How this works

Every question asks about something you can observe without tools and without opening the appliance: which rack came out dirty, whether the pump hums, where the water appears, what still lights up. Those answers lead down different branches, so two people with the same complaint can reach quite different results.

There are 33 symptoms covered across five appliance types. Each one ends with ranked causes, the checks that are safe to carry out yourself, and a clear point at which to stop and call someone.

What it deliberately does not do

It does not give you a percentage or name a single failed part. Nothing here can measure anything inside your machine, so a confident number would be invented. The ranking says which explanations fit your answers best, which is a genuinely different claim.

It will also stop rather than continue where that is the right answer. A gas smell, an electrical burning smell, visible charring or a breaker that keeps tripping all end the flow with what to do instead, and no do-it-yourself steps at all.

Nothing you enter is stored or sent anywhere. The answers live in the page while you use it and are gone when you reload.
