Cove Dishwasher Error Code 600149

Error code 600149 means the diverter valve motor (MOT2) is taking too long to complete its rotational cycles during a wash cycle, a condition called excessive lap time. The most common documented cause is a motor with the wrong frequency rating being installed, such as a 50-Hz motor in a 60-Hz unit or the reverse. This error does not trigger during calibration sequences, only during normal operation. A technician should inspect the motor's frequency rating and compare it to the dishwasher's power supply specification.

It is not recommended to continue running the dishwasher while this error is active. The diverter valve controls water distribution to the spray zones, so a malfunctioning motor can result in poor wash performance or incomplete cycles. Continuing to run the unit with a frequency-mismatched motor can also cause additional wear on electrical components over time.

Repair costs vary depending on the cause. If the fix involves clearing a mechanical obstruction or reseating a wiring connection, costs may be limited to a service call fee, typically in the range of $75 to $150. If the diverter valve motor needs to be replaced due to a frequency mismatch or failure, parts and labor combined can range from $150 to $400 or more depending on your location and the technician's rates.

Basic checks such as inspecting for debris in the diverter valve or verifying wiring connections can be performed by a knowledgeable DIYer after disconnecting power to the unit. However, if the cause is a frequency-mismatched motor, the repair requires sourcing and installing the correct MOT2 motor, which involves working with internal components and electrical connections. Most homeowners will find this repair is best handled by a qualified appliance technician.

Disconnecting power to the unit is the recommended first diagnostic step, but simply resetting the dishwasher will not resolve the underlying cause of error 600149. If the diverter valve motor has the wrong frequency rating or is faulty, the error will return once the unit runs another wash cycle. The root cause must be identified and corrected before the fault will stay cleared.
