Whirlpool Washer Error Code 33

Error code 33 on a Whirlpool washer means the drive motor inverter board has reported a fault. The inverter board controls motor speed and torque during spin and agitation cycles. When it detects an abnormal condition such as overcurrent or overtemperature, it triggers this code and may halt the cycle to prevent further damage.

A power reset may temporarily clear the display, but code 33 will return if the underlying fault in the inverter board or drive motor has not been resolved. Resetting without completing the diagnostic process can mask the problem and delay proper repair. Service mode test 11 should be completed to properly identify the faulty component.

Repair costs depend on which component has failed. A replacement drive motor inverter board typically costs between $80 and $200 for the part, while a drive motor can range from $100 to $300. Adding professional labor, total repair costs generally fall between $150 and $500 depending on the diagnosis, local labor rates, and parts availability.

Diagnosing code 33 requires running service mode test 11, the Spin Test, which involves entering a specific diagnostic mode on the washer. Technicians with experience testing motor windings and inspecting inverter board connections may be able to handle this repair, but the process involves working near line voltage components. If you are not comfortable with appliance electronics, professional service is recommended.

It is not advisable to continue using the washer when code 33 is active. The fault indicates the motor drive system is not operating correctly, and running further cycles could cause additional damage to the inverter board or drive motor. The washer should remain out of service until the fault is properly diagnosed and repaired.
