1. Disconnect power.
2. Remove the water inlet hose. (Note : Be careful of remain water drop.)
3. Remove the left baseboard and middle rear crosspiece.
4. Disconnect the 2 terminal
lugs from the inlet valve.
5. Push the valve from the
lower rear crosspiece to take
it off.
6. Remove the clamp and
disconnect the inlet hose (to
air breaker) from the water
valve.
7. Reverse the above
procedure to install.
1.Open the control panel and take out the PCB;
2.Unplug the CON3 and P4 wires , then use the
multi-meter
shelf to measure resistance
between the blue wire (EV1) and white wire (IS),
the normal resistance is about 3.4K
to 4.3 K .
3. I f 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.
