Cove Dishwasher Error Code 050103

Error code 050103 indicates a hardware fault in the Analog-to-Digital Converter (ADC) circuit within the wash pump drive system. This ADC is part of the Motor Control Module (MCM) assembly and is responsible for converting analog motor feedback signals into usable digital data. When the ADC hardware fails, the dishwasher cannot properly control or monitor the wash pump, and the error is triggered. Replacement of the MCM assembly is required to resolve the fault.

It is not advisable to continue using the dishwasher with this error active. The fault indicates the MCM cannot reliably control the wash pump, which means the dishwasher may not complete cycles correctly or may shut down mid-cycle. Running the unit in this state could also place additional stress on other components.

Repair costs will vary depending on parts pricing and labor rates in your area. The primary cost is the MCM assembly itself, which is a specialized control board component, plus any applicable labor charges if a technician performs the replacement. As a general range, expect total repair costs to fall somewhere between $200 and $600 depending on part availability and service rates in your region.

Resolving this error requires replacing the MCM assembly, which involves working with the dishwasher's internal electronics and electrical connections. Knowledgeable DIYers with experience in appliance repair may be able to perform the swap, but the job does require proper precautions including disconnecting power before beginning. If you are not comfortable working with appliance control boards and wiring harnesses, a qualified technician is recommended.

A reset is unlikely to permanently clear error 050103 because the fault is rooted in a hardware failure inside the MCM assembly. Even if a reset temporarily clears the displayed code, the underlying ADC circuit fault remains, and the error will return once the dishwasher attempts to run the wash pump drive system. The MCM assembly must be replaced to resolve the issue.
