Cove Dishwasher Error Code 600151

Error code 600151 means the dishwasher's diverter valve has been detected in a position that the control board does not expect as the home position. The diverter valve routes water to different spray zones during the wash cycle, and this code indicates that the valve's reported position does not match the required reference point. The appliance stops operation to prevent incorrect water distribution or potential damage.

No, you should not continue running the dishwasher when this code is active. The diverter valve controls where water flows during a cycle, and operating the machine with a valve fault could result in poor cleaning performance or improper water routing. Disconnect power and have the unit diagnosed before running another cycle.

A power reset may temporarily clear the code if the fault was caused by a one-time signal glitch, but it will almost certainly return if there is an underlying hardware problem with the diverter valve, its sensor, or the wiring. Simply resetting the unit without diagnosing and correcting the root cause is not a reliable fix. A proper inspection of the diverter valve system is needed to resolve the fault permanently.

Some steps are manageable for a knowledgeable DIYer, such as inspecting the wiring harness for loose or corroded connectors and checking for physical obstructions around the diverter valve after disconnecting power. However, testing the valve motor and position sensor requires a multimeter and familiarity with appliance electrical systems. Replacing the diverter valve assembly is also a moderately advanced repair, so many homeowners prefer to have a qualified technician handle it.

Repair costs vary depending on what component has failed. If only a wiring connection needs to be reseated or repaired, costs may be limited to a service call fee, typically in the range of $75 to $150. If the diverter valve assembly requires replacement, parts and labor combined could range from $200 to $500 or more depending on your location and the technician's rates.
