Help with worcester 28i junior boiler

[ken b]

Hi new to the forum and have been well impressed with what I have seen so far
Worcester 28i junior boiler

have a couple of problems with this boiler.
1. Keeps losing pressure, repressurise and within 24 hrs the pressure drops to virtually zero, have checked for leaks none found anybody any ideas?
2. The timer has decided not to work, will not come on using the timer, works when you switch to constant, anybody any ideas?


thanks in advance

you could have a deflated expansion. Shouldn't cost much to get someone qualified in.

can only be one of two things. one obvious and one as above.

As long as its the only issue Ken you're looking at 1hr max. However when this fault occurs it usually takes out the relief valve (pipe dripping outside) Put your details up on here and you can PM any one interested and check them out before you give them the go-ahead

As DuncanM mentions it maybe something else entirely. If that something else is the main heat exchanger then you're looking at big bucks to repair...!!! Pay for someone to take a look and pray it's something simple is my advice
