4. Clean the pre-filter (see chapter Cleaning the pre-
filter).
5. Flush dirt residues at the base of the filling nozzle
out through the filling hole.
6. Switch on the pump.
The flow is too small, the dry run fuse has switched off
the pump.
1. Check that sufficient water is present in the suction
container (e.g. water tank).
2. Open the water tap further.
The flow rate increases.
Suction problem due to a leak or a connected water tap.
The pump does not end the suction mode.
1. Open the water tap.
2. Check the system for leaks.
Install a pressure equalization container if the leaks
cannot be eliminated (see chapter Accessories and
spare parts).
The pump stops in Automatic mode, the "Pressure
side error" LED lights up
The pump switches frequently on and off due to leaks.
1. Check the pressure side for leaks (e.g. dripping wa-
ter tap).
Install a pressure equalization container if the leaks
cannot be eliminated (see chapter Accessories and
spare parts).
2. Switch on the pump.
The pressure is too low after switching off the pump.
The device starts again immediately and switches fre-
quently on and off.
1. Increase the pressure at the pressure side.
 For garden applications, use a garden hose with
minimum length of 5 m when the diameter is ¾"
or 15 m when the diameter is ½".
 With a permanent installation, install a pressure
equalization hose or pressure equalization con-
tainer (see chapter Accessories and spare
parts).

2. Switch on the pump.
The pump stops in Manual mode, the "Pressure
side error" LED lights up
The pump runs for at least 4 minutes, although the pres-
sure side outlet (e.g. water tap) is closed. The overheat
protection switches off the device.
1. Pull the mains plug out of the socket.
2. Open the water dispenser connected to the pres-
sure side.
The device is depressurised.
3. Switch on the pump.
The pump capacity drops or is too low.
Dirt particles block the suction area.
1. Pull the mains plug out of the socket.
2. Clean the suction area.
The pre-filter is soiled.
1. Pull the mains plug out of the socket.
2. Allow the pump to cool down.
3. Clean the suction area.
4. Clean the pre-filter (see chapter Cleaning the pre-
filter).
5. Flush dirt residues at the base of the filling nozzle
out through the filling hole.
6. Switch on the pump.
The suction side is leaking.
1. Check the suction side for leaks.
The maximum lifting height is exceeded or the flow rate
is not optimised.
1. Observe the maximum lifting height (see chapter ).
2. If necessary, select a different hose diameter or a
different hose length (see chapter Optimising the
flow rate).
The pressure side outlet is restricted.
1. Fully open the valve or ball tap.
The pressure side hose is kinked.
1. Eliminate the kink points in the hose.
