Washer shows F33, often related to pressure sensor or analog pressure switch

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty analog pressure sensor, blocked pressure hose, wiring fault to sensor, control board analog input failure

Safety first: Unplug the washer.

Clean pressure hose and chamber: As in F04, remove and clean the hose and its connection to the tub.
Check sensor connector: Ensure the multi-pin connector on the analog pressure sensor is secure and clean.

Persistent F33: Replace the analog pressure sensor. If the error remains, the main control board may be defective.
