I thought the Master Valve soleniod was faulty, so I replaced the whole thing. The problem still persists with some changes…
Operating on manual (all stations are ticked with “Activate Master”), I get stations 1 to 4 to work ok. Stations 5 to 10 DON’T althouigh you can hear the station soleniods openning with no water flow, so the master valve is not operating electrically. To double check this I manually opened the master valve and operated all stations in manual mode and they ALL worked.
So if I leave the master valve opened manually the program functions??????
Any ideas?????
Thanks.Andrew
