How to Enter Diagnostic Mode on a KitchenAid Dishwasher

KitchenAid dishwashers are Whirlpool-platform machines: blink-coded faults and the 1-2-3 service-mode entry apply.

Step-by-Step: KitchenAid Dishwasher Diagnostics

1
Read codes as blink pairs (most KitchenAid models flash the Clean/Complete LED: first number, pause, second number — e.g. 7-1 heater).
2
Enter service diagnostics: press any three buttons (not Start/Cancel) 1-2-3, 1-2-3, 1-2-3 within ~8 seconds; all LEDs light and the test cycle steps through each component.
3
7-1 (heater) stops the dry cycle: the heater is metered for continuity at the sump, accessible from below with the unit pulled.
4
The tech sheet pouch behind the kick plate maps all blink pairs for your control.

💡 Good to know: Premium badge, Whirlpool internals — parts and procedures interchange with Whirlpool/Maytag equivalents.

How do I read error codes on a KitchenAid dishwasher? +

Watch the Clean/Complete LED blink pattern: first digit, pause, second digit, long pause, repeat. 7 blinks–pause–1 blink = 7-1, the heater fault.
