Drain Pump Theory of parts -

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.
1. Drain off the water in the dishwasher,
and disconnect the power supply
(Note : Make sure to remove remained
water in the dishwasher. If not, wet the
floor.)
2. Remove four screws on bottom, and
then remove bottom board.
3. Label and disconnect the two terminal
lugs from the drain pump.
4. Remove screws securing the drain pump
to sump, then remove drain pump.
5. Reverse the above procedure to install.

Access drain pump
Inspect drain pump
Check the electric part
1.Open the control panel and take out the PCB;
2.Unplug the CON4 and P4 wires, then use the multi-
meter
shelf to measure the red wire (PS) and white wire
(IS), the normal resistance is about 150 to 220 .
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.
