Cove Dishwasher Error Code 050123

Error code 050123 indicates a fatal IPM (Intelligent Power Module) over temperature error in the wash pump drive system. The IPM is part of the MCM (Motor Control Module) assembly and is responsible for controlling power to the wash pump motor. When the IPM overheats beyond a safe limit, it shuts down the drive system and logs this fault. The dishwasher will remain inoperable until the MCM assembly is replaced and the root cause of the overheating is addressed.

No, you should not attempt to run the dishwasher while this error is active. The fault is classified as fatal, which means the wash pump drive system has been disabled by the control module as a protective measure. Attempting to force the machine to run could cause further damage to the motor or electronics. Disconnect power to the unit until repairs are completed.

Repair costs will vary depending on parts and labor in your area. The MCM assembly for a Cove dishwasher is a higher-cost component, and total repair costs including parts and labor typically range from several hundred dollars to over five hundred dollars. If the wash pump motor is also found to be defective, that will add to the overall cost. Getting a diagnostic quote from an authorized Cove service technician before authorizing repairs is advisable.

The primary repair for this fault is replacing the MCM assembly, which involves working with high-voltage components inside the dishwasher. DIYers with experience in appliance repair and comfort working around electrical systems may be able to perform this replacement. However, because the fault is classified as fatal and involves motor control electronics, most homeowners should have a qualified technician handle the repair. Before replacing the MCM, it is also important to inspect the wash pump motor to rule out a secondary cause.

A simple power reset will not permanently clear this error code because it is a fatal fault tied to a hardware failure in the MCM assembly. Even if the code appears to clear after cycling power, the underlying thermal failure condition will cause it to return as soon as the dishwasher attempts to run the wash pump. A proper repair, specifically replacing the MCM assembly, is required for the fault to clear reliably.
