A customer of mine has a P2 Outdoor with 2 internal dosing pumps programmed to dose upon low pH and low conductivity. They are plugged into the P1 and P2 plugs inside the box. They no longer turn on when ph or conductivity is low and they do not turn on when the manual override buttons on the front are pushed even though the power indicator lights do turn on. I had the customer plug a new pump into the P3 plug and push the manual override and it does not work either. Is there any quick fix for this or will unit need to be replaced? Seems like a motherboard issue. Unit was installed in October.
