What 600149 means on a Cove dishwasher

Error code 600149 on a Cove dishwasher indicates that the diverter valve motor (designated MOT2) has exceeded its acceptable lap time during normal operation. The diverter valve is responsible for directing wash water to different spray zones within the dishwasher, and its motor must complete full rotational cycles within a precise time window. When the control detects that the motor is taking too long to complete these cycles, it flags an excessive lap time fault. This error does not apply during calibration sequences, only during active wash operations.

The primary and most specific cause of this error is a frequency mismatch between the installed diverter valve motor and the electrical supply. Cove dishwashers are built for either 50-Hz or 60-Hz power grids, and the diverter valve motor MOT2 must match the unit's rated frequency. A 50-Hz motor installed in a 60-Hz unit, or a 60-Hz motor in a 50-Hz unit, will spin at the wrong speed, causing the lap time to fall outside the acceptable range and triggering this code.

Because the root cause is most often a hardware mismatch from a prior service visit or incorrect parts installation, resolving this fault typically requires verifying the motor's frequency rating against the dishwasher's power supply specification. The first step before any inspection is to disconnect power to the unit to prevent electrical hazard and to allow the control board to reset before further diagnosis.

Common causes of 600149

  1. 01

    Wrong motor frequency installed

    Part replacement

    A 50-Hz diverter valve motor (MOT2) was installed in a 60-Hz unit, or vice versa. This is the primary documented cause and results in the motor spinning at the incorrect speed, producing excessive lap times.

  2. 02

    Incorrect replacement part ordered

    Part replacement

    During a prior service, a diverter valve motor with the wrong frequency rating may have been sourced and installed. Checking the motor's frequency marking against the dishwasher's rated supply frequency will confirm this.

  3. 03

    Failing diverter valve motor

    Part replacement

    A motor that is wearing out mechanically may struggle to complete rotational cycles within the required time, even if it is the correct frequency rating. Signs include unusual noise from the diverter assembly during wash cycles.

  4. 04

    Mechanical obstruction in the diverter valve

    Wiring / connection

    Debris or scale buildup inside the diverter valve housing can add resistance to the motor's rotation, slowing lap times beyond acceptable limits. Inspect the valve for blockages or binding.

  5. 05

    Wiring or connection issue to MOT2

    Wiring / connection

    Loose, corroded, or damaged wiring connections to the diverter valve motor can cause intermittent or reduced power delivery, affecting motor speed and triggering the lap time fault.

Frequently asked questions about 600149

What does 600149 mean on a Cove dishwasher?
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.
Can I fix error code 600149 myself?
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.
Is it safe to keep using my Cove dishwasher with error code 600149?
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.
Will resetting my Cove dishwasher clear error code 600149?
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.
How much does it cost to repair error code 600149 on a Cove dishwasher?
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.
