leaking Washer on Ariston Microgenus MFFI27 Boiler

Postby Phredda1 » Tue Jun 19, 2018 1:39 pm

I have an Ariston Microgenus mffi27 boiler. The washer on the cold water inlet appears to have gone and the connection is leaking. I've looked at the installation and service manuals, and it appears that the washer fits between a flat surface on the inlet valve and the boiler ( diagram on page 7 of the installation manual), rather than being recessed like a tap connector. Is it possible to change the washer without removing the boiler from the wall?
Thanks in advance...Phredd.
