suprima 60 banging pipes

[sean taylor]

Help please. I have a Suprima 60 which worked fine for several yers. Suddenly I it is heating the upstairs radiators piping hot but downstairs it either hets the radiators for a few minutes and then stops providing them with heat or just doesn't het them at all, while upstairs is fine!
Occasionally I will also get very loud banging around all the pipes.
I have tried bleeding the radiators but there is no air trapped that I can find.
Could this be the pump, PCB or somehow a blockage in the pipes?
Please help 'cos Im sat freezing in my living room while the family sits upstairs. Money is a problem so I need to keep the costs down to parts only if possible.

Your help would be very much appreciated. Thanks.

Its not a boiler problem its a circulation difficulty.

The pump might be a little weak, the system might be a little sludged up or the rads might need balancing.

Try turning down the hottest rads and see what the others do.

Check for 230V at the pump. If it is there then replace the pump.

If 230V is not present check the pcb as this controls the pump.
