Whirlpool Washer Error Code 335

Error code 335 means the compressor motor inverter board has detected and reported a fault. The inverter board controls the compressor motor, and this code signals that something has disrupted its normal operation. The first diagnostic step is checking that the board is receiving the correct supply voltage of 102VAC to 132VAC at connector CN8. If voltage is within range and the fault persists, the inverter board or compressor motor itself may need further inspection.

You should not continue operating the washer while error code 335 is active. The fault indicates a problem with the compressor motor inverter board, and running the machine under this condition could cause further damage to the board or related components. Disconnect power to the unit until the fault has been properly diagnosed and resolved.

Performing a reset by disconnecting power for several minutes may temporarily clear error code 335 from the display. However, if the underlying issue with the inverter board supply voltage, wiring, or the board itself has not been corrected, the code will return once the washer attempts to operate again. A reset is useful for confirming whether the fault is persistent, but it does not substitute for proper diagnosis and repair.

Some causes of error code 335 can be addressed by a knowledgeable DIYer, such as inspecting and reseating wiring connections at the CN8 connector or clearing lint buildup around the inverter board. However, diagnosing and replacing the inverter board or compressor motor involves working with AC voltages and requires proper safety precautions and equipment. If you are not comfortable working with live voltage measurements, it is best to contact a qualified technician.

Repair costs for error code 335 vary depending on the root cause. If the issue is a wiring connection or a loose harness, costs may be minimal, covering only labor if a technician is involved. If the compressor motor inverter board requires replacement, parts and labor combined could range from roughly $150 to $400 or more depending on the specific model and local labor rates. A compressor motor replacement would be at the higher end of the cost spectrum.
