1 WaterLevel 0C/1C
-Inletvalvefailure
-Thecomputerboardisfaulty(theSCRofthewaterinletvalve
isshort-circuited)
-Waterlevelsensorfailure(lessthan20KHzormorethan
50KHzbeyondthenormalrange)
-Theterminalofthewaterlevelsensorisnotpluggedinorthe
wiringharnessisfaulty.
•Replacethewaterinletvalve
