Hi

Bought my place two years ago and I'm not sure how old the Vaillant
242E/284E is. At any rate, one year ago had a problem with the valve
that let's out excess pressure. That cost over £100 in London in
workman charges alone - and he didn't even replace the valve, it just
worked again after fiddling with it.

Now, this weekend, the boiler has just stopped working - it turns on
for a few seconds, fires up, then makes an awful screeching noise,
turns off while it's making the screeching noise, and then a few
minutes lates, stops screeching, fires up for a few seconds, and the
cycle repeats. I've tried it a few times now, same thing

I'm thinking now of getting a Worcester-Bosch 30CDi which is apparently
a little more than I need, but for £50 extra, I'd rather have it. My
reasoning for a new boiler a

1) I'm not a handy man, so can't fix these things myself. With a new
installation I can get it insured.

2) The newer boilers have this 'instant hot' thing which I like the
sound of.

3) When the man came round to fix the current boiler last time, I got
the feeling the parts weren't that easy to come by.

4) A plumber from my current builders has offered to install it for
free.

Any suggestions/recommendations? Obviously looking to move very quickly
on this, as it's rather cold!

Sounds a bit like the pump is jamming. First of all if its a sealed
system,check your water pressure guage and top it up if necessary to
about 1 Bar cold temperature. If the water pressure is ok then see if
you can access the pump and if it has a large chrome slotted cap on
the front of it (usually Grundfos make,plum coloured or similar) take
the cap off,use a small screwdriver to manually operate the pupm
impeller to free it/check rotation. Spares for Vaillant shouldnt be a
problem.

I would think the pump ..no circulation ..over heats .. cuts out ..
cools re-lights .. and so on .. pump change is quite easey .. just make
sure to bleed all the air out after or it wont run ... or you could
try bleeding it first .. may be just air locked ? i think you should
get water out of the pump when you remove the screw bung on the read of
the pump . may be just silted up

This boiler ought to be fixable - whilst (IMHO) it is not Vaillant's best
offering it's still above many of the cheaper models.


1) I'm not a handy man, so can't fix these things myself.

This is uk.d-i-y however knowning when to get help (which varies from job
to job and person to person is p-art of the suject.


With a new
installation I can get it insured.

This boiler is not old enough for BG and others to stop supporting yet.

2) The newer boilers have this 'instant hot' thing which I like the
sound of.
That feature helps a little but the layout and size of the house is more
significant.


3) When the man came round to fix the current boiler last time, I got
the feeling the parts weren't that easy to come by.

Completely untrue. Furthermore the pressure relief valve is a generic
part.


4) A plumber from my current builders has offered to install it for
free.

What exactly is going to be installed at no extra charge?

Check system pressure and pump. Probably all it needs.
