SOLUTIONS
Remove it and take it to an Official Technical
Service centre
Clean or replace with new one
Check that the voltage is the same as that shown
on the specifications plate
Adjust the suction height
Replace fuse or thermal relay
Remove the pump and go to an Official Technical
Service centre
Submerge the suction pipe properly
Fill the pump body with water
Ensure good ventilation
Ensure that connectors and seals are leaktight
Check programming
Find the reason for the loss of water
Open the valve or tap
Wait till the level is restored and press reset
Ambient relative humidity, max.: ............... 95%
Motor class I.
