Check/Action Remedy
The motor is broken.
The motor capacitor
is broken.
9
The driving belt
or driving wheel is
broken.
Check if the motor starts.•
Check the wiring and con-•
nections between motor
and PCB, motor and motor
capacitor.
Check if the motor is ener-•
gized but not running. The
motor makes a humming
sound.
Make sure that the pump is •
not blocked by trying to turn
it by hand.
If the motor starts, remove •
the cover and check the
status of the driving belt.
Change the PCB. If this does not solve the
problem, put the old PCB back and then,
replace the motor.
Change motor capacitor. If this does not solve
the problem, test changing the PCB.
If the pump is blocked and cannot be turned
by hand - change the pump.
Replace the defective driving belt or driving
wheel.
Filter I, stop or warn-
Alarm, water leak/
condensation on the
base plate under the
lters.
10
Alarm, too low pres-
sure. (General.)
11
Low pressure
warning.
Low pressure
stop.
Check for water on the base •
plate. Wipe away the water
and restart.
Remove the top of the water •
purier.
Restart the water purier. •
Let it to produce water to
determine the position of the
leakage.
If water is detected, check:
that the lter containers are tightened, x
for water on top of the lter lids, and x
the connections to the lid. x
If water leaks from the lter container/lter
lid, change the o-ring. If this does not solve the
problem, replace the container or the lter lid.
Change the leaking component.
If the product is restarted with an open valve
and it does not produce any water - or - if
the lter I warning diode was not lit prior to
emergency break, the cause might be a valve
problem or an erroneously calibrated inlet
pressure sensor. Otherwise, this problem is
most likely due to a too low feed pressure and
high pressure drop in lters.
