- After ensuring clear drainage, plug in and restart the machine to see if the error clears.
Technician Only Diagnose and repair drain pump drive circuitry
- Isolate and test the drain pump motor and rotor for free movement and electrical continuity.
- Inspect wiring harness and connections between the control board and the drain pump/TRIAC circuit.
- Test or replace the TRIAC or related driver components on the control board if found faulty.
- Verify proper functionality of the drain sensing circuitry and replace components as needed.
Parts needed: Drain pump assembly, Control board (drain TRIAC/sensing circuit), Wiring harness/connectors
