W
rong Installation/Leakage
1. Check whether the drain hose is
laying down on the floor.
(For pump model)
2. Check where water leaks.
Pressure Switch
1. Check the pulsator is rotating when
water fills continuously.
2. If there is no defect in the pressure
swith, 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.
Ball Pressure Sensor
(WF-T652A, T452A, 402)
1. Check the pulsator is rotating when
water fills continuously.
2. If there is no defect in the Ball
Pressure Sensor , check whether
the air hole of the outer tub is
blocked.
Drain hose

Water leaks
from a part.
It doesn’t

Blocked.
Water fills.
It doesn’t
rotate.
Blocked.
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.
Water pressure is
not sensed.
Air hole blocked.
The drain hose
should be hung on the
stand-pipe or the tub.
Change the part.
Repair it.
Check the tube of the
pressure swith,if it is bent
or blocked, repair that.
Repair the blocked hole.
Change the inlet valve.
Change the controller.
Check the tube of the Ball
Pressure Sensor, it is bent
or blocked, repair that.
Repair the blocked hole.
12-4. Water doesn’t come into the wash bowl.
Where, what & how to check? Result of Check Possible Cause How to repair & settle
Pressure Switch
1. Is there PE error on the display
which means pressure switch error
2. Check frequency of the pressure
switch without load if wash is
proceeding without filling.
Controller
1. Defect of controller is highly possible
if inlet valve and pressure switch have
no defects in the above.
Reconnect the connector
or change leads. Change
the pressure switch if coil
is open.
Change the pressure
switch.
Change the controller.
PE Error
displayed.
Less then
26.2kHz
Connector is taken
off, or lead or coil is
open.
Defect of the
pressure switch.
