SOLUTIONS
1) Check the presence of voltage in the power supply grid
2) Activate the circuit breaker again. If this trips again, contact
a qualified electrician
3) Disassemble the hydraulic part and control if the rotor turns
correctly
4) Control the operation by manually raising the float. In case
of breakdown, change it.
