Defective valve
Check any leaks
from the sides of
inlet valve
1. Inspect the insertion of
PCB pin
2. Unavailable power or
water supply to inlet valve
terminal
1. Water supply starts
promptly when the power
is turned "ON".
supply continues even when
the power supply is cut off
1. Examine the operation/
water supply of inlet valve
2. Examine the drainage
through the drainage hose
3. Check any impurities in
valve housing
Inpsection Method
Check whether the inter-terminal
resistance of inlet valve is 4.3kΩ
Unplug the inlet hose and then check
the impurities
Check the malfunctions in valve
Check the connection of connector
with naked eyes
Check whether the inter-terminal
resistance of inlet valve is 4.3kΩ
Check any disconnections in wiring
-> Inspect circuit
