Cove Dishwasher Error Code 050104

Error code 050104 indicates a fatal IPM overcurrent shunt error in the wash pump drive system. The Intelligent Power Module detected current exceeding its safe threshold in the circuit that drives the wash pump motor and shut the system down. This is a protective fault designed to prevent damage to the motor and control electronics. The dishwasher will not resume normal operation until the fault is diagnosed and resolved.

No, the dishwasher should not be used while this fault is active. The code is classified as a fatal error, meaning the control system has already shut down the wash pump to protect against further damage. Attempting to force operation could damage the IPM, the pump motor, or associated wiring. Address the root cause before running another cycle.

Because 050104 is logged as a fatal error, a simple power reset is unlikely to permanently clear the fault if the underlying problem has not been fixed. The machine may restart temporarily, but the IPM will detect the overcurrent condition again as soon as the wash pump is called to run. The root cause, whether a blockage, a failed motor, or an electrical fault, must be corrected first for the error to clear and stay cleared.

The first step, checking for a blockage inside the wash pump, is something many homeowners can perform by accessing the pump area at the bottom of the dishwasher tub. If clearing a blockage resolves the fault, no parts are needed. However, if the issue involves a failed pump motor, damaged IPM, or wiring fault, those repairs typically require disassembly of the base panel and familiarity with electrical components, making a qualified technician the safer choice.

Repair costs vary depending on the root cause. If a simple blockage is the problem, there is no parts cost involved. Replacing a wash pump motor on a Cove dishwasher typically runs in the range of $150 to $400 including labor. If the IPM or control board requires replacement, costs can range from $250 to $600 or more depending on parts availability and service rates in your area.
