SOLUTIONS
Check fuses and other protection devices
Check that the pump is completely submerged
Check that the voltage is the same as indicated
on the name plate
Reset the thermal protection or wait for it to cool
Connect this line to the outlet of the pump
Install the gate valve on the outlet to reduce the
flow of the pump
Clean intake filter
Wait for the well to recover
Install the valve in the opposite direction
Contact an Official Repair Center
See wiring diagram
Replace the line with a new one
Check the power cable
