Fault
The pump does not start
up, or stops suddenly
during operation
The pumping capacity
decreases
The delivery rate is too
low
Quick-Connect cannot
be opened or closed
The pump runs although
the level sensor has no
contact with the water

Subject to technical modifications.
Cause
The power supply is disconnected.
The thermal protection switch has
switched off the pump because of over-
heating.
Dirt particles block the suction area.
The level sensor stops the pump.
The level sensor does not react because
it is soiled.
The suction area is clogged.
The maximum delivery head is exceed-
ed.
The hose diameter and the hose length
have been selected incorrectly.
The push-fit system is dirty.
The level sensor does not react because
it is soiled.
The switch is set to Manual mode (MAN). 1. Set the switch ´to Automatic mode (AUTO).
The level sensor is dirty.

Rectification
1. Check the fuses and the electrical connec-
tions.
1. Pull the mains plug out of the socket.
2. Allow the pump to cool down.
3. Remove any dirt particles in the suction ar-
ea.
4. Clean the suction area.
5. Prevent the pump from running dry.
1. Pull the mains plug out of the socket.
2. Clean the suction area.
1. Check the position of the level sensor and
correct if necessary.
Note
The pump stops 15 s after the level sensor no
longer has contact with the water.
1. Clean the level sensor.
1. Pull the mains plug out of the socket.
2. Clean the suction area.
1. Observe the maximum delivery head, see
chapter Technical data.
2. If necessary, select a greater hose diame-
ter or a shorter hose length, see chapter
Optimising the flow rate.
1. Remove the clip.
2. Clean the clip.
3. Install the clip.
1. Clean the level sensor.
1. Clean the level sensor.
Optimising the flow rate
The flow rate is further increased:
● The lifting height is reduced.
● The diameter of the hose used is increased.
● The length of the hose used is decreased.
● The smaller the pressure loss caused by the con-
nected up accessories.
