KitchenAid dishwashers are the reason this page exists — they are the most common machine in the county wearing this badge, and they report faults two ways depending on age. Newer models show an F-and-E code on the display. Older ones blink the clean light in a pattern, and that pattern is a code even though it does not look like one. Counting it properly is the difference between us arriving with the right part and arriving to look.
Codes are not standardised between manufacturers, and they move between model years within one. Everything below is what these codes mean on the series named beside them — if your model is older or newer, treat this as a strong hint rather than a verdict, and send us a photo of the model plate when you book. That plate settles it, and it takes ten seconds.
On models with a display, the code appears when the cycle aborts. On models without, watch the clean light: it flashes in groups separated by a pause, and the number of flashes in the first and second group is the code. Count both and tell us, or film ten seconds of it on your phone — that is genuinely as useful as the number.
