SOLUTIONS
Disassemble it and take it to an Official Technical
Service
Clean the filter
Check geometric height and load losses
Make sure the mains frequency and voltage
correspond to what
characteristics plate.
Make sure the suction remains submerged
Check fuses and other protection devices
Disassemble it and take it to an Official Technical
Service
Work with an appropriate temperature
Revise the programming
Reset the control and find out why there is
insufficient water
Wait for the water level to be restored and press
the reset button
Repair the leak
Reset the thermal protector or wait until it cools down
Wait until the well level is restored
Check electrical cable
Revise the connection according to the diagram
provided
Open the valve
Repair the leak
