fix or replace worc 24cdi?

you can also do this job by removing the entire water section and the gas valve. takes best part of 2 hours to do it and it's not that easy but i've done it 3 times before when i wasn't able to remove the boiler from the wall.

For repair on any of the water valves CH flow/return or cold water isolation, the boiler has to come off the wall.
Drain completely.
Dismantle the flue (elbow), remove electrical connection, undo the prv connection, remove the three 10mm bolts on the bottom of the frame and two 10mm nuts at the top of the boiler, needs two of you (realistically) to lift it from its jig.
Replace leaking valve (cold water isolation valve means dismantling/re-assembling bottom jig), replace ALL o-rings to ALL valves and refit boiler in reverse order being very careful not to pinch or snag any of the new o-rings (use lots of silicon grease).

NIGHTMARE job!
Good luck! :o))
