Troubleshooting
DANGER
To avoid risks, all repairs and replacement of spare parts may only be carried out by authorized customer service
personnel.
First pull out the plug from the mains before carrying out any tasks on the machine.
Fault Cause Remedy
Pump runs but does
not transport
Air in the pump see chapter “Preparing the Appliance”
Air does not come out on the pressure
side
Open tap on pressure side
No water available. Check the water reservoir.
Pump does not run or
suddenly comes to a
standstill during oper-
ations
Power supply interrupted Check fuses and electrical connections
Thermal protection switch in the motor
has switched off the pump as it was over-
heated.
Pull out the mains plug, let the pump cool down,
clean the suction area, prevent dry running
Note
The cooling down time until the motor starts up
again can be up to 150 min.
Pump switches itself
off and back on
Thermal protection fuse has switched the
pump off to protect from overheating or
turned it back on after it has cooled off.
In order to prevent a repetition, the system should
be checked for leaks and sealed.
Motor starts up imme-
diately after switch off
Pressure is not retained in the system Check connections including sealings and control
the water outlet.
The smallest of leakages can affect the operation
adversely.
Air pressure in the storage boiler is too
low.
Fill storage boiler with 2.0 bar. See chapter “Main-
tenance”
Backflow valve does not close properly Check backflow valve on suction side.
Membrane in pressure tank is defective Replace membrane
Pump transports is re-
ducing or transported
quantity is too low
Suction filter or check valve (special ac-
cessories) contaminated
Clean suction filter or check valve (special acces-
sories)
The quantity transported by the pump de-
pends on the transport height and the
connected periphery
Keep max. flow height, see technical data. If nec-
essary, select a different hose diameter or hose
length.
Vibrating sound while
taking out water
Membrane in pressure tank vibrates Noise caused by operations and the noise can be
reduced by reducing the pressure in the air filling of
the storage tank.
