The boiler in my S26 seems to be well and truly over-filling. Can someone please advise what the correct level should be?

On our machine, the problem was quite intermittant and seemed to be temperature related, i.e. when it was hot the fault would occur more frequently. The fill solenoid would click on and off but sometimes it would not flick off before reaching the anti-vac and it also sprayed out the safety valve and sent the pressure guage to about 3 bar (mains water pressure here). I also cleaned the level probe and checked all the wiring connections. I did find the earth point brass bolt was rusted, but after replacing this the problem was still there. Finally I have removed the electronic auto fill box (i believe this is the GICAR you are referring to) and found that the 5A relay had contacts that were fried. On our machine the relay (inside the GICAR black casing) has a clear casing and you could clearly see the charred contacts and plastic surrounds. Obviously underrated for the job. This relay switches the water fill solenoid on and off and is a prime suspect in the fault. I am currently waiting for a new relay to arrive and with some help from an electronics expert here we will replace it and let you know if that solves the problem. Sorry to post before we know for sure that the problem is solved, but the coincidence in our faulty machines is pretty interesting i think!
