I have a sureflo pump with digistream controller, today whilst working the controller and pump just turned off for no reason. Then when i went to turn it back on it wouldnt turn on i waited about 20 minutes then it turned on. started cleaning a gain and when i detatched the wfp and it was reading dead end it turned off again same thing but had to wait 30 mins before it would come back on, then same thing happened twice more and i'd had enough for the day. its a new battery all the connections seem to be fine and the pump and controller seem to work fine when on. This keeps happening when the system comes up with a dead end but usually a dead end is fine for example its dead ended when i go from the front to the back of the house etc and no issues in the past with doing that. On one occasion today as i was walking back to van it was flashing the warning pressure switch but again no issues with that in the past. Can anyone shed any light on this situation its driving me insane there doesnt seem to be much of a pattern to it so i can't work out where the issue is.
