Possible Causes

Faulty drain pump drive circuit, wiring issue to pump, defective pressure sensor, control board fault

Safety first: Unplug the washer before servicing.

Step-by-step:

Check pump: Verify the drain pump runs during drain. If not, test for voltage at the pump during drain (requires live testing—only if qualified).
Inspect wiring: Check harness from control to pump and pressure sensor.
Test pressure sensor: Verify readings per tech sheet.

When to call a technician: F33 often indicates a control-level issue; professional diagnosis is usually required.
