• Anerroroccursifanincorrectwaterlevel
sensorisused.Makesuretocheckthe materialcode.(Abnormaloperation)
• Ifthewaterlevelsensorisfaulty,replaceit. • Iftheerrorpersistsdespitetakingtheaction
above,replacethePBA.

- Checkthevoltagewhenthe
powerison.
► UNIVERSALMOTOR ChecktheResistanceofNos.1 and4ofthewirepinontheside oftheTACHOSENSOR. - Resistance:Approximately
40to45Ω(Normal)
► THREEPHASEMOTOR MeasuretheResistanceofNos. 2and3ofthewirepinonthe sideoftheHALLSENSOR. - Therevolutionofthedrum
