Cove Dishwasher Error Code 050135

Error code 050135 on a Cove dishwasher indicates a fatal wash pump drive system fault caused by an I2T overcurrent shunt error. The Machine Control Module (MCM) monitors current draw through a shunt resistor in the wash pump motor circuit. I2T protection is a thermal modeling calculation that measures current squared multiplied by time, used to detect sustained overcurrent conditions that could cause motor or drive component damage. When the MCM detects excessive current during motor speed ramping across 10 consecutive startup attempts, it triggers this fatal error and locks out further operation to prevent damage.

This fault points specifically to the wash pump drive circuit, which is responsible for spinning the wash impeller and circulating water through the spray arms. The overcurrent condition during speed ramping suggests the motor or its drive electronics are encountering abnormal electrical resistance or a mechanical load that forces the motor to draw more current than the control parameters allow. Fatal classification means the dishwasher will not resume normal operation through a simple reset cycle, as the MCM has logged a persistent failure pattern across multiple startup attempts.

Common sources of this fault include damaged or pinched wiring in the wash pump motor harness, a failing wash pump motor with degraded windings, a seized or partially obstructed pump impeller, or a failed motor control drive board. Because the fault occurs during speed ramping rather than at full operating speed, the problem often lies in the electrical path or motor condition rather than a transient mechanical jam. Harness inspection is the appropriate starting point, as wiring faults are among the most frequent triggers for shunt-detected overcurrent errors.
