Mend Grundfos 15-50 Central Heating Pump

grundfos selectric 15-50?

Central heating working ok but hot water only luke warm.
Large screw ! in center of pump is pointing to '130' on face.Is this correct ?
System has been running for 3 yrs with annual service.
Is it a faulty change over unit / pump or the control unit ?
Any ideas before I call my heating engineer with his hammer!

Hi Brian
Thanks for the info.It seems to be the Mid Point Actuator playing up and that will have to wait until the weather warms up so that I can drain the system,at least the central heating is OK.

Hi, the large screw is just an outer one, it closes off the access to the end of the pump shaft, makes no odds where the slot is as long as its not weeping. Your problem could be a sticking valve.They do have manual over-rides on them so you could open it manually.
