I believe there is some kind of a small clutch that fits on the 5mm dia splines that engages when its pulled outwards....and this has come off and fell inside the pump. just guessing.

It's a "Circulating Pumps Ltd CP61" used to be "Myson"

I'm fitting a new pump head on to my Potterton 80 combi... But I'm a bit concerned about the Pump starter Knob I unscrewed it like the the manual says and pulled it out to engage the spindle but to my supprise it came out of the head all the way and I ended up with it in my hand and I noticed...

I presume that to fit the new pump head, I will have to drain the CH system first..We've enough flooding out side the house at the moment and I don't want it inside as well....and will a CP53 Head fit direct to a CP61 pump..or will I have to replace the whole unit???.

Seems to work ok on hot water...In fact it's hotter than normal...Tried that part number on Google and E-bay and came up zero...I'll try and find a potterton parts supplier on monday.

Brilliant deduction it was the pump...Hoooray. I didn't check it before cos iwas only using it for domestic supply......It's a Myson Compact CP61..What is the best replacement part if I cant find one like it....And question can I still us the domestic supply with the pump disconnected?.

Well I disconected the Gas Valve Solenoid..But it blew the fuse again...I've read somewhere on the Forum that a suppressor capacitor on the Spark Generator could cause this but I'm not sure if it was the same model boiler they were talking about.

Just in case it was a solenoid..I swapped boards for a new spare one that I had...but the fault was still the same so I suspect its something not on the main board...I was wondering about the other board at the back with the spark generator gubbins ..Could there be anything that could have...

Hi and thanks for for quick response..The fused mains switch is a 3 amp ...It works just as you'd expect it to, right up to the point where it should ignite and the green light goes on and on the ignition click the 2A blows...The fan sounds as if it works ok.

My Potterton 80 has gone on the blink again..This time its blowing the 2 Amp fuse on the PCB..it appears to blow on the ignition sequence as the Domestic supply is turned on. any ideas on how to test for the fault.

Thanks lads..the jobs done ..the wife an kids are happy..I couldn't have done it without your help and support ..Power Station boilers are more in my line..so if you need any help with your local Power station boiler let me know.

Iv'e just checked it out with the fault finding chart and it seems to be working ok now..all I need to do is get the the water temp up a bit..how is this done?..You see i'm an electrical/mechanical engineer not a plumber.

Re Potterton Combi 80. When the C.H. is off I can't get any Domestic hot water..so I leave it on all the time and turn the thermostat down to zero, and it works fine..whats the problem?..I think it might have something to do with the diverter valve...advice please??.

Hi Chris ..What sort of price ?...Would an Honest guy like you charge for such an item.

I found the manual went through the troubleshooting chart and found the pcb was the fault so I removed it and just as you said it had burned out at the top left hand corner..I managed to resolder and all is now well and everything is up and running. do you know what causes this problem is it a...
