The boiler at the van here has started acting up

water with all sorts of boiling and gurgling and rattling

flame off.....The problem is intermittant but a pain to
listen to and I am sure it is not doing the boiler any
good....any ideas? .....before I get a man in

Given you don't seem able to lookup up its flow switch
assembly you will definitely need to get someone in to
replace this or diagnose the problem.

so...where is it?


If you can't recognise it then definitely get a man in.

going to....

The part is most likely:

nah that is some kind of temperature sensor clamped around the pipe

Assuming you are taking a photo from below?

Â*Â*https://www.plumbase.co.uk/flow-swit...000043-3529181


that will be it but I cant find it........

As another poster has said I would check using a meter before
replacing.

I would if I could find it.....

oh wait... the thing on the right of the photo...yes that will be
it.....

just been back down because the gas safe man couldn't come until
next week...took the valve off ...dead easy just got a exact
replacement for £41 at heat spares Govan... fitting it
tomorrow.....wish me luck

Have you inspected the unit? Does it use a rotating vane to check
for water flow?

Or is flow sensed by pressure difference in which case there will be
2 holes either side. One could be blocked.

they seem to have a bit of plastic inside which is hinged and I
assume makes a contact to turn on the flame when the water is flowing
and breaks when the flow stops.....there are four screws on the unit
so I will take the old one apart tomorrow ...

If it now moves freely then refit it and it may well work trouble free
for a few more years.

Why can't you test the contacts with a multimeter? You do have one?


It's old it has failed It was Friday I had two hours to get from Girvin
to Govan to get a new one I bought a new identical one it was only £40
I'm going to fit the new one today why fart about....yes i have loads of
multi meters I even have an AVO ......not that interested in why it
failed I'm only interested in getting the boiler to work again sorry to
disappoint you.....
that is it fixed....video to follow of the great jubilation in the van
here now we have hot water again and not just steam coming out of the
taps........tee hee
