4) Water doesn't come into the wash tub.
Where, what & how to check?
Ball Pressure Sensor
(Pressure Switch)
1. Is there PE error on the display which
means Ball Pressure Senosr (Pressure
Switch) error
2. Check frequency of the Ball Pressure
Sensor(Pressure Switch) without load if
wash is proceeding without filling.
Controller
1. Defect of controller is highly possible if
inlet valve and Ball Pressure Sensor
have no defects in the above.
5) Water fills continuously of intermittently
Where, what & how to check?
Wrong Installation/Leakage
1. Check whether the drain hose is laying
down on the floor.
2. Check where water leaks.
Ball Pressure Sensor
(Pressure Switch)
1. Check the pulsator is rotating when
water fills continuously.
2. If there is no defect in the Ball Pressure
Sensor(Pressure Switch), check
whether the air hole of the outer tub is
blocked.
Inlet Valve
1. Does water fills even though it is not
energized (power is off)?
Controller
1. Does water fill immediately after the
power switch turns on before pushing
the START/PAUSE button.
Result of Check
PE Error displayed.
Connector is taken off, or
lead or coil is open.
Defect of the Ball Pressure
Sensor (Pressure Switch)

Possible Cause
Reconnect the connector or
change leads. Change the
Ball Pressure Sensor
(Pressure Switch) if coil is
open.
Change the Ball Pressure
Sensor (Pressure Switch).
Change the controller.
Possible Cause
The drain hose should be
hung on the stand-pipe or
the tub.
Change the part.
Repair it.
Check the tube of the Ball
Pressure Sensor (Pressure
Switch), it is bent or blocked,
repair that.
Repair the blocked hole.
Change the inlet valve.
Change the controller.
