7.2 Electronic issues and their solution
• Pressing the start button the system starts but goes into alarm after about 20-25 seconds.
Check if the watermaker is in hydraulic block (pressure indicated by the pressure gauge above 9-10 bar and
pump start/stop continuously). In this case, carry out the reset procedure indicated in the manual and restart
the system.
• If the system still does not start (it goes on the block after about 20 seconds), activate the system
manually by inserting the bypass.
• If the system works correctly (normal pressure/normal output) it could be just a probe issue. In this
case disconnect the 2 cables of the pressure switch from the PCB of the controller, then connect
the 2 cables to a meter in ohm position. The pressure switch must give, under normal conditions,
a closing signal followed by an opening signal, every 3-4 seconds. If the signal is always open or
always closed, the pressure switch must be replaced
