Agora-Tec AT-house waterworks 5-1300-3DW, 5-stage centrifugal pump with max: 5.6 bar and max: 5400l / h and pressure switch with dry-run protection
The pump has run, only the pressure switch was not working. Had he himself screw and replace a cable (brown and green yellow). It was also at a terminal, the cable loose. But so far everything is going after that round. Just something must not be.
