The list below shows some possible malfunctions of the device, possible causes and tips on their elimination. All
the measures referred to may only be carried out with the pump being separated from the electrical mains. If you
yourself feel unable to eliminate any of these malfunctions, please contact the customer service department or
your point of sales. Any repair beyond the scope speci ed below must only be performed by quali ed sta .
Please bear in mind that all warranty claims will become void in the case of damage caused by inappropriate
repair attempts, and that we decline any liability for any ensuing damage.
1. The pump is not discharging
any liquid, the motor is not
running.
