TROUBLE DIAGNOSIS
Will Not Start
• Plugtheunitintothewalloutlet.Checkforpropervoltage.
• Checkfuseorresetcircuitbreaker.
• PushanykeytoturnonthewasherandpresstheStart/Pausekeytorunthewasher.
• ClosedoorandpushtheStart/Pausekeytorunthewasher.
• Checkifwasherisinapause,soakorsudsprocess.Waitbrieyanditmaystart.(Ifthewasherisinsuds
period,Sudswilllightupinsteadofremainingtime.)
• Checkforrestricteddrainsystem.(Ifthereiselectricalproblemindrainsystem,“NODraining”errorwilloccur
after15minutes.)
• CheckWaterSupply.
• Checkthelineorwatervalvescreenlter.
• CheckifPCBconnectorsareassembledLCD/LEDproperly.
• CheckifCN6terminalsonPCBareingoodcondition.(RefertoPCBConnectorCheck.)
• ReplacePCB.
Leaking
• Makesureinlethoseconnectionsarenotleaking.Checkforrubbergasketdamageduetoovertightening.
• Checkstandpipeforleak.Wrapadryragaroundthestandpipeopening.
Ifragbecomeswet,leakisfaultofhomeplumbing.
Besurethestandpipeiscapableofacceptingtheowofwaterfromthewasher.
• Makesureendofdrainhoseiscorrectlyinsertedandsecuredtodrainstandpipe.
• Checkinternalhoseconnections(ll,drainsystems,dispenserhoses&clamps).
• Checkrubberboot.Remove,repositionandreinstall,ifnecessary.
• Checkforpossiblekinkeddispensertooutertubhose.Hotwaterpressurizationmayforcedooropen.
No Tumble
• Startnormalcyclewithanemptymachineandallowalltochecktumble.
• PerformQuickSpinTest.(Beforetest,makesurethatthetumblerisempty.)
• CheckforlooseconnectionsatMachineControlBoard,PressureSwitch,Motor,TachHarnessandMotor
