5.3.4. Inspect inlet valve
5.3.4.1. Check 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 resistance between the
blue wire (EV1) and the blue wire (ACN), the normal resistance is about 3.4K
Ω
to 4.4K
Ω
.
3. If the measured resistance is not correct, it means the valve coil is broken or the 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 valve.
4. If the resistance is OK, we need to inspect the valve body.
5.3.4.2. Check machine part
1. If the electric part is OK, we need to check the machine part.
2. Check the valve filter. if the valve filter is blocked, we need clear the residues.
3. If the valve filter is clear and the valve can’t inlet water, check whether valve can act or not. If it isn’t, we need replace the
valve.
4. If the water is continue entering, we need replace the valve.
