Whirlpool dishwashers flag faults with an F# code on most models, or an F#E# pair on newer control boards. This page lists every Whirlpool dishwasher error code documented on DiagnosFix, each linking to a full breakdown of likely causes, first checks, and what to avoid. If you’d rather start from the symptom instead of the code, our dishwasher troubleshooting hub covers issues beyond error codes, and our dishwasher repair cost guide helps you weigh repairing against replacing once you know what’s wrong.
A code varies by model: the same code can have a different meaning depending on the brand and model. Always check your appliance’s manual before acting.

Some Whirlpool dishwasher control boards use an extra digit or a slightly different format than what’s listed here. If the exact code you’re seeing isn’t above, check your owner’s manual for the model-specific list before assuming a part has failed.
