How to Fix
- 1
Check wiring connections between the washing motor and the main PCB (connector RD3). Reconnect if disconnected.
- 2
Check whether the washing motor impeller is locked (foreign object or debris). If locked, replace the pump casing assembly.
- 3
Measure washing motor resistance at connector RD3 (Pin1~Pin2, Pin2~Pin3, Pin3~Pin1 individually): nominal is 22.5-24.9 ohm at 20°C. Replace the pump casing assembly if out of range.
- 4
After pulling out the RD3 connector, check whether the resistance between any pin pair reads 0-5 ohm (short). If shorted, replace the pump casing assembly.
- 5
If motor resistance is correct and connections are good, replace the main PCB assembly.
