Sorry for the delay in replying DavecUK I had to go away for a while to visit my Dad.
I got the package from ACS, thank you very much Paolo, and it was the solenoid coil rather than the entire solenoid - as you describe it DavecUK.
It was easy to remove and replace, the most difficult thing was disconnecting the wires with long-nose pliers, once done it worked without any problems and my morning coffee is, once again, flowing. I so missed it 😄
Thank you all for your help.
