• Air leaks in pressure sensor hose
• Defective PCB
• Low frequency from pressure sensor
• Defective PCB
• Impurities in air trip inlet
• Defect in pressure sensor (Defective oscillating condenser)
• Impurities in air trip inlet
• Defective PCB
• Water supply
continues despite
the high water
level.
• Display of "E9"

Water continues
to be supplied
although the
inlet valve is
functioning well.
Defect in the bellows of
water level sensor
Check the frequency Exchange the water
level sensor
"E2"
Defect in pressure sensor
hoses
Check the frequency Exchange the hose "E2"
Inspect any openings Exchange the hose "E2"
Blockages in pressure
sensor hoses
Inspect with naked eyes Remove impurities "E2"
Occurrence
of "E9"
The water level
sensor transmits
the frequency of
15KHz or lower
or 30KHz or
higher.
Disconnected connector Inspect the connection of
connector with naked eyes
Re-insert "E9"
Defect in water level
sensor
Check the frequency Exchange the water
