Pump intermittent running

Unread postby Bigstew » Thu Sep 20, 2018 9:03 am

Bloody pump has packed up. Flipped the Bm over and disconnected the pump, all clean and dandy pump only works when you give it a twist to help it going, it then turns for a few seconds then stops. Press the button again then nothing, press the button again and it spins freely and the whole cycle repeats itself. I think its knackered unless anyone has any ideas or previous experience with this please. Its only 3 years old.

What controller?
If new, goes it suffer from condensation?
Use a multimeter on the output from bm to check voltage.
Maybe check resistance on pump? Not sure about pump.
Might need a new pump.

Which BM. Which pump?

Does it run without the impeller off?
