Whirlpool Dishwasher Error Code FCE0

FCE0 means the Electronic Control Module (ECM) and the main control board have lost communication with each other. This fault is triggered when the communication bus between these two components carries no valid signal. Common causes include loose wiring at the ECM, a faulty connection on the ECM power supply lines, or a damaged communication harness. The dishwasher will not run until the fault is resolved.

No, the dishwasher should not be operated while FCE0 is active. The fault indicates the control system cannot properly coordinate functions between the ECM and the main board. Running the unit in this state could result in unpredictable behavior or incomplete cycle execution. Resolve the fault before returning the appliance to service.

If the fix is simply reseating a loose connector, the cost is minimal and may only involve a service call fee, typically in the range of $75 to $150. If the ECM or main control board requires replacement, parts alone can range from $100 to $350 or more depending on the specific model, with additional labor costs on top. Getting a diagnosis before committing to a repair is the best way to understand the total cost.

In many cases, yes. Start by unplugging the dishwasher, then locate the ECM and firmly reseat all wire connectors, paying close attention to the L1 and neutral power connections. Remove the ECM cover, restore power, and check whether diagnostic LEDs D30, D31, and D32 are lit or flashing as expected. If the error clears after reseating connections, no parts replacement is needed, but if LEDs remain off or the fault returns, further diagnosis or a replacement board may be required.

A power reset may temporarily clear the code, but it will return if the underlying connection or component issue has not been addressed. Because FCE0 is tied to an active hardware communication failure, simply resetting the unit does not fix a loose connector, damaged wiring harness, or failed board. A proper inspection of the ECM connections and wiring is necessary for a lasting repair.
