Hi guys,

Didn't work over Xmas and went to start work this week and the controller was flashing ps which I've since found out is the pressure switch. Everything seems to be in order no air locks etc..

Is it just a case of replacing the switch? It's only a year old pump

Thanks!

 try gently tapping the pressure switch.

HI the controller is showing the pump pressure switch has activated.
This may be due to a pressure build up in the system or a loose electrical connection. The Controller carries out a test to ensure the pump is in circuit. A faulty connector, damaged cable or even loose connection to the battery terminal or connector could be the cause of the issue.
