Problems 

               Possible causes

                       Solution

 pump does not stop

  1. Water leakage higher than 1.2l/min at some point.

  2. Manual start switch (RESET) is blocked.

  3. Breakdown on the electronic board.

  4. Incorrect electric connection on electronic board.

  1. check the system, the tap, etc

  2. Press it for several times. Consult your dealer if the problem persists.

  3. proceed to its substitution

  4. check the connection (line and motor)

 pump does not start 

  1. Not enough water supplies, the security system have been activated and LED (Failure) is on. 

  2. Pump is blocked: LED (Failure) is on and the security system is activated. When we act on the manual start switch (Reset) the LED (ON) is activated but the pump doesn't work.

  3. Failure in the electronic circuit 

  4. No electrical supply 

  5. Not enough pump pressure

  6. air in the pump aspiration

  1. Check the water supply and restart the pump through the reset switch (Reset).

  2. Consult your dealer.

  3. Switch off power supply, wait a few seconds and turn it on again. If the pump doesn't start immediately then replace the circuit.

  4. Check the proper electric feeding. The tension LED (POWER) should be on.

  5. The security system has been activated and the corresponding LED (Failure) is on. Check that the pump pressure is 0.8bar higher than the starting pressure of the controller.

  6. The pressure gauge will indicate a pressure lower than the nominal or constant oscillations. The security system will act by stopping the pump and the LED (Failure) will be on.

 the pump starts and stops repeatedly

 Small leakage in some point of the installation

 Verify possible tap of tank leakages and repair them.
