Supplying water for washing/ pre-washing and bleach
Cause Diagnosis of Defect
Check for tap opening.
Check if resistance between water supply valve terminals is
within 4320~5280Ω.
Remove water supply hose and check for foreign substances in
filter.
-
Visually check connector connection status.
Check if resistance between water supply valve terminals is
within 4320~5280Ω.
Wiring short -> Conduction test
Refer to water level sensor defect check method.
Check for blocking of holes in pressure hose.
-
Floater restraint, loosening -> S/W not working
Check for leakage through the sides of water supply valve.
