Inspect Drain Pump - Panasonic NP-6F2MUQNZ-NZ Service Manual

Inspect drain pump

5.4.4.
5.4.4.1. Check the electric part
1. Open the protecting box and take out the PCB.
2. With the door closed,unplug the CON3 and ACN wires, then use the multi-meter Ω shelf to measure the red wire (PS) and
blue wire (ACN), the normal resistance is about 150Ω to 190Ω.
3. If the measured resistance is not correct, it means the pump coil is broken or connector is loose. In this case, we should check
the connection first. If the problem hasn't been solved by re-connection, we should replace the drain pump.
4. If the resistance is OK, but it also can't work, maybe the magnetism is too weak, so we need to replace the drain pump.
5.4.4.2. Check the machine part
1. If the electric part is OK, we need to check the machine part.
2. Remove bottom board.
3. If the non-return valve is wrongly assembled, the tub will remain much water. We need to re-assemble the non-return valve.
4. If the drain pump is working, but no water drain out or just a little. We should check the drain hose or drain body.
