5) Water fills continuously of intermittently
Where, what & how to check?
Result of Check
Possible Cause
How to repair & settle
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.
Drain hose laying
down.
Water leaks from a
part.
It doesn’t rotate.
Blocked.
Water fills.
Wrong installation.
Defect of the part.
Water pressure is not
sensed.
Air hole blocked.
Defect of the inlet valve.
Short circuit of the
triac of the
controller.
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.
4) Water doesn’t come into the wash tub.
Where, what & how to check?
Result of Check
Possible Cause
How to repair & settle
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.
PE Error displayed.
Less then 26.2 kHz
Connector is taken off, or
lead or coil is open.
Defect of the Ball Pressure
Sensor (Pressure Switch)
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.
