Hi, I have been trying to re-connect my 3 pump Gen 1 doser - it has not been used for a while.. However with no luck as the Comms light fails to light, even when using the cable that is currently connected to the Powerbar (non-pab) to reprogram. Additionaly none of the pumps will run on manual when pressing the red buttons. (the power light comes on ok )

Taking a look inside the unit I would guess the issue is with the front panel/CCB as there are some signs of very minor water ingress! Are spare parts available?
