The boiler at the van here has started acting up
today.....sometimes when you turn the hot water off the flame
stays on and you can hear it boiling the now static water with
all sorts of boiling and gurgling and rattling
noises......must be the flow sensor not turning the boiler
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:
Â*Â* https://ibb.co/gMBrbsC

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?
