Whirlpool Dishwasher Error Code 8-5

Error code 8-5 on a Whirlpool dishwasher indicates an electrical problem in the drain motor circuit. The fault can be either a loose connection somewhere in the wiring between the control board and the drain motor, or an open winding inside the drain motor itself. Either condition prevents the motor from operating correctly, which can cause the dishwasher to stop draining.

It is not recommended to continue running the dishwasher while code 8-5 is active. A non-functional drain motor means water may not be evacuated from the tub, which can lead to standing water, potential leaks, and additional strain on other components. Disconnect power and address the fault before resuming use.

Resetting the dishwasher by disconnecting power for a few minutes may temporarily clear the code, but the error will return if the underlying electrical fault is not repaired. Code 8-5 reflects an actual fault condition in the drain motor circuit, so a reset alone is not a fix. The wiring connections and motor winding resistance need to be inspected and corrected before the code will stay clear.

Some causes of code 8-5 are within reach of a knowledgeable DIYer. After disconnecting power, you can inspect and reseat wiring connectors in the drain motor circuit and check for visible wiring damage. Testing the drain motor winding resistance with a multimeter is also a straightforward step. However, if the motor winding is open or the control board has failed, those components will need to be replaced, which may require a technician depending on your comfort level.

Repair costs vary depending on the root cause. If only a connector needs reseating, there may be no parts cost at all, though a service call from a technician can run anywhere from $75 to $150 or more. If the drain motor requires replacement, parts typically range from $50 to $150, with total repair costs including labor often falling between $150 and $300. A failed control board will generally push costs toward the higher end of that range.
