Installation Guide

7. Fault Finding
Warning
Remove the fuse, pull out the plug, or switch off the power supply. Make sure that the power supply
cannot be accidentally switched on. All rotating parts must have stopped moving. The product must
only be serviced by trained service personnel.
a) Supply failure
b) Fuse blown. If new fuse blows at
once, either cable or motor is faulty
c) Impeller/grinder stuck. Thermal
switch tripped.
d) Pressure switch pipe blocked.
Reestablish the power supply.
Replace the fuse. Measure cable &
motor. If cable or motor is defective,
replace the defective parts.
Free the impeller/grinder, & wait
until the motor is cooled down &
the thermal switch has reset.
Remove the pressure switch &
clean the pipe.
3. Motor runs continuously or at
irregular intervals.
b) Water leaking back into tank
from discharge pipe.
c) Pressure switch defective.
Remove blockage.
c) Hydraulics or grinder blocked
Replace the pump housing (service
part).
Check and clean the hydraulics &
grinder.
Replace the carbon filter.
8. Water from shower or another
appliance connected to the lower
inlets drains off slowly. Backflow
from the lifting station.
a) Non-return flap in inlet stuck,
does not open or does not close
sufficiently.
Check the non-return flap.
b) Hydraulics or grinder
blocked.
Check and clean the hydraulics &
grinder.
Use a pipe with a larger diameter.
c) The start level has changed.
Check and clean the pressure switch
pipe.
d) Inlet pipe diameter is too
small.
1. Motor does not start when the
level in the tank reaches the start
level.
2. Motor hums but does not
operate.
a) Impeller/grinder stuck.
Free the impeller/grinder & check
that it can rotate freely.
b) Motor or capacitor defective.
Replace the motor or capacitor.
c) Control board defective. Replace the control board.
Check for leaking appliances. a) Water leaking from inlet into tank.
Check the non-return flap.
Replace the pressure switch unit.
4. Motor runs but does not
evacuate water.
a) Pump or tank blocked.
b) Air lock in pump or vent hole in
pump housing blocked.
Check operation of vent valve in the
tank. Check that the carbon filter is
not wet. Check that the vent hole in
the pump housing is not blocked.
c) Discharge port or pipe is blocked.
Remove blockage. Check the non-
return flap.
5. The lifting station evacuates
slowly.
a) Discharge pipe is too long or has
an excessive number of bends.
Increase discharge pipe size. Alter
pipework to reduce number of
bends. Change bends to soft bends.
b) The pump housing is leaky.
Fault Cause
Solution
6. Rattling noise from the lifting
station, but water is evacuated.
a) Foreign body hitting the impeller/
grinder.
Remove the foreign body.
7. Odor from the tank.
a) Carbon filter contaminated
