Cove Dishwasher Error Code 050140

Error code 050140 indicates a fatal I2T overcurrent error in the wash pump drive system detected during steady-state operating speed. The Motor Control Module logged an overcurrent condition during normal running speed across 10 consecutive startup attempts, triggering a fatal shutdown. This points to a sustained electrical or mechanical problem with the wash pump motor, its wiring harness, or the impeller assembly.

Start by inspecting the wash pump motor harness for damaged wiring, corroded connectors, or pinched conductors. Next, check the pump impeller for blockages or debris that could be binding the motor. If the harness and impeller are clear, the pump motor itself likely needs to be tested for proper winding resistance and replaced if faulty. In cases where the pump and harness check out, the Motor Control Module may need to be evaluated by a qualified technician.

Repair costs vary depending on the root cause. Clearing a pump impeller blockage is typically a low-cost service call. Replacing a wash pump motor or harness generally falls in the range of $150 to $450 depending on parts and labor in your area. If the Motor Control Module requires replacement, costs can be significantly higher, often in the $300 to $700 range or more. A technician diagnosis is recommended before estimating the total repair cost.

A simple power reset is unlikely to permanently clear this code because the MCM records the fault across 10 continuous startup cycles, meaning the underlying problem is persistent rather than intermittent. Even if a reset allows the machine to restart temporarily, the fault will return as soon as the pump encounters the same overcurrent condition. The root cause must be diagnosed and repaired first.

No. Error code 050140 is classified as a fatal error, meaning the dishwasher has disabled itself to prevent further damage. Running a dishwasher with an unresolved overcurrent condition risks overheating the motor, damaging the Motor Control Module, or creating a potential electrical hazard. Do not attempt to bypass the error or force the unit to run until the underlying cause has been identified and corrected.
