√ Ifnotinsertedintothebracket-heater,ittouchesthedrumandcausesnoiseandelectricleakage.
AFTER SERVICING
• Checkthewiring.
√ Ensurethatnowiretouchesarotatingpartorasharpenedpartoftheelectricalharness.
• Checkforanywaterleakage.
√ Performatestrunforthewashingmachineusingthestandardcourseandcheckwhetherthereisanywater
leakagethroughtheoorsectionorthepipes.
• Donotallowconsumerstorepairorserviceanypartofthewashingmachine
themselves.
√ Thismayresultinpersonalinjuryandshortentheproductlifetime.
• Ifitseemsthatgroundingisneededduetowaterormoisture,makesuretorun
groundingwires.
(Checkthegroundingofthepoweroutlet,andadditionallygroundittoametallicwater
pipe.)
√ Failingtodosomayresultinelectricshockduetoelectricleakage.
 [Runningagroundingwire]

Features Description
Bubble Wash ●BubbleCushion
-EcoBubbletechnologyactivatesthedetergentmuchearlierandfasterinthewash
cyclebyuseofaBubbleGenerator,rapidlymixingasmallamountofwaterwithair
anddetergent(workswithpowder,tabsorliquiddetergents).Thiscreatesafoam
cushioninthedrumaheadofintroducingthemainwaterintake.
●Superenergysaving
-thedetergentinfusedbubblespenetratethefabricsmuchfasterandefcientlythan
foraconventionalwashsystem,deliveringacleanerwashperformanceespeciallyfor
coldertemperaturecycles.Thelowerthewatertemperatureofthecycle,thegreater
