6.- POSSIBLE PROBLEMS, CAUSES AND SOLUTIONS
Possible fault
The pump does not start up and
the general switch is activated.
The electric pump starts up but
the thermal circuit breaker
activates immediately or the fuses
blow.
The electric pump starts up too
frequently.
The pump start up the first time
and stops after 10", showing a
fault.
The pressure or flow are
insufficient.
The tank fills up very slowly.
The installation general circuit
breaker activates.
The installation differential circuit
breaker activates. ("Short
circuits")
If the problem persists, or the solution is not found in the table, consult the specific pump information or refer to an
official technical service.
Cause
Failure of electrical supply.
The thermal circuit breaker for the pump
has been triggered.
Fuses blown or thermal magnetic circuit
breakers triggered.
The tank is empty.
Motor overload.
Supply cable damaged.
Thermal circuit breaker or fuses not
adequate for the motor current.
Supply voltage not between the motor
limits.
Loss of water in the retention valve
incorporated in the equipment.
Water loss in the installation.
Empty tank.
Leaks in the intake pipes.
There are air pockets in the installation.
Total pressure valve allowance greater
than that provided for.
Forgetting to prime the pump.
Intake filter is obstructed.
Short circuit
Leak to earthing.
Restore the supply.
Wait until the pump motor cools down. If the
error persists consult the technical service.
Check that the pump is well ventilated.
Change fuses or close thermal magnetic circuit
breakers and check the pump consumption with
the nominal value of the circuit-breakers.
Check the water intake valve
Check the working conditions of the electric
pump and replace the thermal circuit breaker.
Repair the supply cable.
Check and if necessary replace the
components.
Check the supply voltage of the motor and on
the electrical supply circuit.
Check that there isn't any debris that impedes
correct closure of the valve.
Check the installation to find the faults. Repair
or replace the components.
If it is not possible to fix the faults, install a
hydrosphere as per chapter 3.1.2.
Check the water intake valve
Check the pipes.
Turn on various taps and push the reset button
and wait until all the air exits the installation.
Check the pressure valve allowance and the
loss of pressure.
Fill the pump body with water.
Clean the filter.
Check the connection cables.
Check the state of the installation in the electric
pump and in the cables.
