Cheer muggles. That’s fair enough. For info I took the new fan off this morning and refitted it, cleaned up all the electrical connections, unplugged and replugged all the connectors on the pcb, checked the flue was all clear and gave everything else a general clean and it’s working again. I’m...

Hi, I have a Potterton Suprima 50L which has had previous PCB issues but they were solved by resoldering the board and I haven’t had a lockout problem for >2 years. The bearings on the original fan went recently so I replaced the fan and the boiler was working fine. For about 48 hours. Now the...

Ianmcd, the removable part of the valve contains the motor only. The circuitry remains attached to the mechanical part of the valve so the only way I can see to completely eliminate this as the source of the problem would be to replace the whole valve

Thanks TCCHeating. I've already removed the head by pushing in the two plastic retainers on the side. This removes the motor and housing only. Since my original post, I've managed to get to the two microswitches by removing a plastic cover containing the circuitry (diode, microswitches...

I'm having problems with my central heating and suspect the 3 way valve. The valve is a Siemens MA V322C. The system provides hot water only unless I use the manual override on the valve. I've tested the grey and white wires feeding the valve and these behave as expected depending on the status...

I have been using an Ariston integrated dishwasher daily for the last 3 years without a problem, but last night it tripped the RCD. It must have been about 3/4 the way through the cycle and when it tripped there was a strong burning smell. I reset the RCD and turned the dishwasher back on and it...

Hi, I installed the new synchron motor last night and everything is now working. All didn't go smoothly though, since the cog on the new motor was only half the length of that on the original. This meant that it didn't engage properly with the ratchet on the valve unless I physically...

I already threw caution to the wind and tried turning the cog with the power on and off last night. With the power off it turns, albeit very slowly but when the power is on, it doesn't budge at all. I'm going to pick up a replacement motor at lunchtime and try it tonight. Will let you know...

I looked at the valve again last night. As well as the manual lever to open the valve, there is a switch that seems to trigger the pump and the boiler. When I hold both open, the central heating kicks in. So it does seem to point to the synchron motor. When there is power to this motor it...

Thanks, I already took the cover off the valve and the motor doesn't turn at all. When should the pump kick in, in relation to the valve operation? If the valve is set to CH or CH and HW, I would have expected the pump to be operating? Cheers, Andrew

Hi, I have a similar problem to a previous poster on this site, but with enough differences to make me need to post this. I have a system that consists of a boiler (potterton but still working), indirect cistern, single pump and 3 port valve ( Siemens MA-V322C). The HW is working fine but...
