Cove Dishwasher Error Code 800179

Error code 800179 means the dishwasher control board has detected that the drain pump is disconnected or not responding to commands. The control system sends a signal to activate the drain pump and either receives no response or detects an open circuit. The dishwasher halts the cycle until the issue is resolved to prevent water overflow or further damage.

A reset may temporarily clear the error code and allow the dishwasher to restart, but if the underlying fault with the drain pump or its wiring is still present, the code will return as soon as the control board attempts to activate the pump again. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for diagnosing and correcting the root cause.

Repair costs vary depending on the root cause. If the issue is only a loose connector or debris in the pump, the cost may be limited to a service call fee, typically in the range of $75 to $150. A drain pump replacement, including parts and labor, generally falls in the range of $150 to $350. Control board replacement is the most expensive scenario and can range from $250 to $500 or more depending on parts availability and labor rates in your area.

Some causes of this error, such as a loose harness connector or a jammed impeller, can be addressed by a confident DIYer comfortable working around appliance wiring. However, replacing the drain pump or diagnosing a control board fault typically requires disassembling the dishwasher and using a multimeter to test components, which may be better suited to a qualified technician. If you are not comfortable working around electrical components, scheduling a service call is the safer option.

Running the dishwasher with an unresponsive drain pump is not recommended. If the pump cannot expel wastewater at the correct points in the cycle, water may back up into the tub or leak, potentially causing water damage to the surrounding cabinetry or flooring. The dishwasher should remain out of service until the drain pump issue is resolved.
