Cove Dishwasher Error Code 050136

Error code 050136 indicates that the Motor Control Module detected a peak wash pump current exceeding 800 mA, triggering an I2T overcurrent fault in the wash pump drive system. This is classified as a non-fatal error, meaning the appliance may continue to function while the condition is present. The fault points to a problem with the wash pump, its wiring harness, or the motor itself. Diagnosis should start with a physical inspection of the pump motor harness.

Because this error is non-fatal, the dishwasher may keep running, but ignoring it is not recommended. A pump motor drawing excess current can overheat over time, potentially damaging the motor, the Motor Control Module, or associated wiring. Addressing the root cause promptly helps prevent a minor fault from becoming a more expensive repair.

Repair costs depend on the root cause. Clearing a blocked impeller involves no parts cost and minimal labor. Replacing the wash pump motor typically runs in the range of $150 to $400 including parts and labor, depending on service rates in your area. If the Motor Control Module requires replacement, costs can be higher due to the part price. Getting a diagnostic inspection first will help identify the least expensive path to resolution.

Some causes of this error are DIY-friendly, such as clearing a blocked pump impeller or reseating a loose harness connector. However, replacing the wash pump motor or Motor Control Module requires disassembly of the dishwasher and comfort working with electrical components. If you are not confident working around appliance wiring, it is safer to contact a qualified technician.

A reset may temporarily clear the error, but the code will return if the underlying cause has not been corrected. Because the MCM monitors pump current continuously during operation, any condition that keeps current above 800 mA will retrigger the fault. A reset is useful for confirming whether the fault is intermittent, but it is not a substitute for diagnosis and repair.
