Whirlpool Dishwasher Error Codes — Complete Error Code Diagnosis Guide

Eleven Whirlpool dishwasher guides are collected here, including one that is not a code at all: a page on lights flashing or blinking, which is how portable models report trouble without a display. F6E1 and F6E4 are the inlet valve and the flow meter, F8E1 a slow drain and F8E4 the drain pump. F7E1 is water not heating in time, F3E1 the combined thermistor and optical water sensor, F9E1 the diverter motor that switches spray-arm feeds, FAE1 the detergent dispenser, F2E1 a stuck button, and F1E1 the door-mounted control board.

Two of these guides are about parts that only exist because the machine tries to be clever, and they are worth knowing before ordering: the optical water-clarity sensor in F3E1 fouls with food film and reads like a dead part, and the diverter in F9E1 jams on a single food particle. Both are cleaning jobs before they are purchases. FAE1 is usually caked detergent rather than a failed wax motor, and F8E1 starts at the filter rather than the pump.

F1E1 explains a hazard particular to this design: the control board lives in the door, where steam intrusion corrodes it, so a machine that has been drying with the door shut has been aging its own electronics. Line voltage runs into that door on a wet cabinet, which makes the breaker the first move. Nothing here is gas or sealed-system work.
