Cove Dishwasher Error Code 050139

Error code 050139 means the Motor Control Module detected that the wash pump motor temperature exceeded 140°F during two consecutive measurement trials, triggering a fatal overtemperature shutdown. The dishwasher stops operation to protect the motor from permanent damage. This is not a minor warning and requires hands-on diagnosis before the unit can be safely returned to service.

No. Error 050139 is classified as a fatal fault, and the dishwasher is designed to stop operation when it occurs. Attempting to force the unit to run with an overheating motor risks burning out the motor windings, damaging surrounding components, or creating an electrical hazard. Do not use the dishwasher until the root cause has been identified and corrected.

Repair costs vary significantly depending on the root cause. Clearing a clogged filter or removing a pump obstruction costs little to nothing if done yourself. Replacing a wash pump motor on a Cove dishwasher typically runs anywhere from $200 to $500 or more in parts and labor, depending on your location and service provider. If the Motor Control Module requires replacement, costs can be higher. Getting a diagnostic visit from a certified technician is the best way to get an accurate estimate for your specific situation.

Some steps, such as clearing a blocked filter, removing a pump impeller obstruction, or inspecting the motor harness for obvious damage, can be performed by a confident DIYer. However, testing motor winding resistance, diagnosing MCM faults, or replacing the wash pump motor typically requires proper tools and familiarity with appliance electrical systems. If you are not comfortable working with appliance wiring or internal components, a qualified technician is the safer option.

Because 050139 is a fatal error, a simple power cycle or reset is unlikely to clear the code permanently. The MCM requires the measured motor temperature to return to a safe range across two measurement trials before it will consider the fault resolved. If the underlying cause, such as a failing motor or blocked impeller, has not been corrected, the error will return as soon as the unit attempts to run.
