9. TROUBLESHOOTING
Before doing any troubleshooting on the appliance, it is necessary to disconnect any supply for at least 5 minutes.
Be sure that the main supply cannot be accidentally turned on.
(General issues)
PROBLEM
PROBABLE CAUSES
POSSIBLE REMEDIES
The pump does
not stop
Water loose greater than 1l/min through
the tube.
Check the closure of the valves involved.
Manual button of starting (RESET)
blocked.
Act on the button many times, in case of
anomaly persistence, contact the technical
service.
Failure in the electronic card.
Replace the circuit board.
The pump does
not start
No electrical supply.
Check the proper electric feeding. The voltage
LED (POWER ) should be on.
Not enough water supply, the security
system has been activated and the LED
(FAILURE ) is on.
Check the water supply and reset the pump
through the reset switch (RESET ).
Pump is blocked: LED (FAILURE ) is on,
the security system is activated.
When you act on the manual start switch
(RESET ) the LED (ON) is activated but the
pump does not work: contact your dealer.
Failure in the electronic card.
Replace the circuit board.
Not enough pump pressure: the security
system has been activated and the
corresponding LED (FAILURE ) is on.
Make sure that the pump pressure is higher
than the starting IDROMAT pressure and that
the highest point of the plant is lower than the
value reported on the technical table.
Air in the pump suction: the pressure
gauge will indicate a pressure lower than
the nominal one or constant oscillations.
The security system will act by stopping the
pump, the LED (FAILURE) will be on.
The pump
starts and stops
repeatedly
Small leakage in some point of the
installation.
Check if there is a leakage from the tap or
water closet, and fix them. If the system does
not reach the restarting pressure, the FAILURE
led flashes.
Subject to modification.
