Whirlpool Washer Error Code 220

Error code 220 on a Whirlpool washer indicates a Blower Motor Inverter Fault. The inverter board that controls the blower motor has detected a fault condition and reported it to the main control. This can be caused by incorrect supply voltage to the inverter board, a failed inverter board, or a faulty blower motor. The machine will not operate normally until the underlying issue is corrected.

You should not continue using the washer while error code 220 is active. The fault indicates the blower motor inverter board is not functioning correctly, and running the machine in this condition could worsen the damage to the inverter board or related components. Discontinue use until the fault has been properly diagnosed and repaired.

Resetting the washer by unplugging it for a few minutes may temporarily clear the code, but if the underlying fault condition still exists, code 220 will return once the machine attempts to run the blower motor. A reset alone does not fix the root cause. Proper diagnosis of the supply voltage at CN8, the inverter board, and the blower motor is necessary to permanently resolve the fault.

Some causes of error 220 can be addressed by a knowledgeable DIYer, such as checking the outlet voltage, inspecting the CN8 connector for loose or corroded pins, and examining the wiring harness. However, diagnosing components like the inverter board and blower motor requires a multimeter and familiarity with AC voltage testing. Replacing the inverter board or blower motor is a moderate-to-advanced repair that involves working near line voltage components.

Repair costs depend on what component has failed. If only wiring or a connector needs attention, costs could be minimal. Replacing a blower motor inverter board typically runs between $150 and $400 depending on the part and labor rates in your area. Replacing a blower motor can add additional parts and labor costs to that range.
