- Check electrical connections: fuse, circuit breaker, main switch or ground
connection.
- Check the supply voltage.
- Check the electrical cable for bending.
- Check diaphragm assembly (seized or locked or frozen)
- Check that the pump is not clogged with debris and that there is water
coming in.
- Check the condition of the inlet hose (clogged, bent, etc.).
- Check the supply voltage.
- Remove debris from pump inlet/outlet valves or from inflated/dry valves.
- Check for cracks in the pump body.
- Check the diameter of the pipe: a valve that is too closed or a pipe that is too
small can restrict the pumping.
- Caused by vibrating pipes.
- Caused by too little water entering (clogged strainer, bent pipe, restrictive
valves).
- Check that the pump is not connected directly to a rigid pipe.
- Check that the pump is mounted on a flat surface.
- Check that there is no air in the pipework.
- Check that all screws are tight.
- Check that the pump diaphragm is not punctured.
The list below shows some possible malfunctions
of the device, possible causes and tips on their

eliminate any of these malfunctions, please contact
the customer service department or your point of
sales. Any repair beyond the scope specified below
must only be performed by qualified staff. Please
bear in mind that all warranty claims will become
void in the case of damage caused by inappropriate
