    Hi All, new member here.
    I have a Wilo Gold RS50 pump fitted to a solar thermal system. I suspect the capacitor is faulty and wish to replace it. However, I cannot see the method to disconnect one of the capacitor leads (sited between the L & N connections). It is very tight and I don't want to damage the connection such that I cannot install the new one.
    The other capacitor lead is held in with a clip and is easy to remove.
    Any advice appreciated.

    Caps are easy come by Town. So long as the same capacitance (Farads) and type is chosen it'll work.

    Cheers guys. I can't think why they would solder one side in but not the other?? It looks just like it's pushed in but I don't want to yank on it too hard and potentially damage the connection. Unfortunately the orientation of the pump makes it difficult to access too. I would swap the pump but the main complication is that the system is pressurised and full of glycol. I was hoping a new capacitor would be an easy/cheap fix...

    Because they may prefer to sell you the full pump , maybe .

    I will try but it's difficult to get the phone behind the pump. You can't really see anything much - just the wire disappearing into a hole...

    No. Sorry Shaun. Use Wago blocks as both safer & reusable as cannot be overtightened.

    I did wonder about that. I reckon there is just about enough room.

    You can buy smaller caps of same rating, they just cost £1 more ;)
