Here's my headache for anyone that can help...
Fitted new Shurflo pump. All wired correct. The first time I tested it no problems but I had to fix leak at DI, all done so re tested but no water coming through so I disconnect the DI but still no water, so I cranked pump up which motor was running fine, still no water and then pump stopped and was flashing 'p'. instructions say p means max pressure reached but nothing more, no troubleshooting on how to fix.
