7.1 Service documentation
Service documentation is available at www.product-
selection.grundfos.com.
If you have any questions, please contact the
nearest Grundfos company or service workshop.
7.2 Maintenance
The lifting station does not require any special
maintenance, but we recommend that you check
operation and pipe connections at least once a year.
Change the carbon filter once a year.
See section 7.4 Service instructions.
7.3 Adjustment of run time
The default setting ensures proper operation in most
pipework. If the pipework is particularly long or short,
it may be necessary to adjust the run time.
For a guide to adjusting the run time, see
www.product-selection.grundfos.com.
7.4 Service instructions
Thanks to the product design, service is easy in case
of malfunction or blocked pump.
Digits in the following sections refer to the pictures in
the appendix at the end of this booklet.
Impeller/grinder stuck
1.1 Disconnect the power supply.
1.2 Unscrew the plug in the cover.
1.3 Insert a screwdriver (min. 110 mm) through the
plug hole and into the slot of the shaft end.
Turn the shaft right and left to free the impeller/
grinder from dirt.
1.4 Fit the plug, and switch on the power supply to
check if the impeller/grinder can rotate freely.
Operation by means of a power drill
2.1 If the product cannot be operated by electrical
power, disconnect the power supply and empty
the toilet and tank by means of a power drill.
Pressure switch pipe blocked
3.1 If the water level in the tank is above the motor
flange, disconnect the power supply and drain
the tank by means of the drain hose
(accessory).
3.2 Unscrew the cover.
3.3 Pull out the complete pressure switch.
3.4 Check and clean the pressure switch pipe.
Foreign body in tank
If the water level in the tank is above the motor
flange, disconnect the power supply and drain the
tank by means of the drain hose (accessory).
Unscrew the cover. See 3.2.
4.1 Remove the four screws of the motor flange.
4.2 Lift the motor flange to reduce the compression
of the O-ring. Insert a screwdriver into the notch
underneath the supply cable and press it down.
4.3 Lift out the complete motor-pump unit by the
handles.
4.4 Check and clean the tank and impeller/grinder.
Carbon filter
5. Replace the carbon filter once a year to ensure
sufficient filter function.
Warning
Before carrying out any service work,
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.
Note
The pressure switch unit can be removed
separately.
Caution
Make sure that the little tube in the top of
the pipe did not become blocked when you
cleaned the pipe!
Note
Lubricate the sealing area of the pressure
switch for easier fitting.
Note
Lift the unit vertically before tilting it!
Warning
Beware of the sharp edges on the grinder.
Wear protective gloves.
Note
Instead of using a carbon filter, Sololift can
also be vented through a venting pipe. In
this case a venting valve is needed.

9. Fault finding
See also section 7.4 Service instructions.
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.

trained service personnel.
Fault Cause Remedy
1. Motor does not start
when the level in the
tank reaches the start
level.
a) Supply failure. Reestablish the power supply.
b) Fuse blown.
If new fuse blows at once,
either cable or motor is faulty.
Replace the fuse.
Measure cable and motor. If cable or
motor is defective, replace the defective
parts.
c) Impeller/grinder stuck.
Thermal switch tripped.
Free the impeller/grinder, and wait until
the motor is cooled down and the
thermal switch has reset.
d) Pressure switch pipe blocked. Remove the pressure switch and clean
the pipe.
2. Motor hums but does
not operate.
a) Impeller/grinder stuck. Free the impeller/grinder and check that
it can rotate freely.
b) Motor or capacitor defective. Replace the motor or capacitor.
c) Control board defective. Replace the control board.
3. Motor runs
continuously or at
irregular intervals.
a) Water leaking from inlet into
tank.
Check for leaking appliances.
b) Water leaking back into tank
from discharge pipe.
Check the non-return flap.
c) Pressure switch defective. Replace the pressure switch unit.
4. Motor runs but does
not evacuate water.
a) Pump or tank blocked. Remove blockage.
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 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.
Change pipework to reduce number of
bends.
Change bends to soft bends.
b) The pump housing is leaky. Replace the pump housing
(service part).
c) Hydraulics or grinder blocked. Check and clean the hydraulics and
grinder.
6. Rattling noise from the
lifting station, but
water is evacuated.
a) Foreign body hitting the
impeller/grinder.
