hi all
newbie here so please forgive any faux pas on my part
had the above boiler fitted 3 years ago and have had a trouble free time till now ,had it serviced every year and occasionally filled it up via the filling loop when rads have been removed for decorating etc etc.

anyway on thursday i noticed the house was rather cold so went to turn the heating on ,and although the boiler would light up it would quickly shut down with the "shutdown due to insufficient water circulation" L.E.D. on
the strange thing is it will still heat up enough water for the tank built into the boiler,but the central heating is stone cold

had the engineer who fitted it round and he checked a few things,the timer was haywire and not programmable so he removed as per book,he checked the pump and the pump is fine
and he checked some of the currents and they are fine ,so his opinion is that it could be the "motor 3-way valve"
but,big but
he mainly works on baxis and pottertons so he told me to try and find someone familiar with these boilers and ask if this is a normal kind of fault on this model,before we replace the part?

also if anyone knows where i can buy ariston spare parts i would be very grateful,whenever i find i site it goes on to fridges and washing machines

many thanks in advance with any other possible suggestions, i moderate on a different building site and to date have answered over 2000 building queries ,so hopefully someone can bail me out now

thanks tony

I dont think much of your installer, thats all he probably can do!

Checking the operation of a diverter valve actuator is so basic !!!

Spares are available from a Wolsey Parts Center.

I always view unpaid moderators as people who like to fuel their power complex, a bit like traffic wardens, but at least they are paid a little. Whats your reason?

i asked for consideration as a newbie,so judging by your omnipotent tone i said something wrong

thanks for the wolsey tip

what i was trying to ask is this a common fault?

oh and my reason for unpaid moderation is that i find it interesting
i see you help quite a lot of people here agile,i'm sure you, the same as I , find it a way of unwinding after a hard day at work.

because i was a regular replier at the site i moderate on, the host asked me to moderate which only involves removing spam.

regards tony

I suspect that you are helping people with replies with the moderation being a minor issue. The problem is that a few people deal with it in another way!

A year or two ago some moderators on this site were deleting and editing about 30 posts every day. Luckily the Owner has realised that it works much better with minimal intervention and I would say that the site is WAY better now with virtually no abusive postings at all, without external influence there is a kind of self control.

I treat diagnosing boiler faults on a forum like a crossword, incomplete and cryptic clues, but its nice to get the right answer without much real information. Its also relaxing late in the evening.

I cannot answer your question about a fault being common because there is no defination and in any case its irrelevant to you. Your concern is solely whats wrong with your boiler and how to sort it out.

We often see the same faults on certain models but if its only one in 100 boilers or less then its hardly common statistically.

Most boilers fail with a real fault every 2-3 years after five years. That excludes sludge which is the installers fault and not the boilers!

yes
maybe it came across wrong,we dont moderate any posts for triviality or even off topic just porn and spam frees up the owners time
anyway cheers will try wolsey for the parts
thanks

Ive never played with one of these.

Generally speaking then cos I can't be asred digging out the manual:-

Looking for something that impedes the flow!

Dig out your manual and look for a filter in the circuit. Often found on the return. Perhaps it is blocked
Your diverter valve could indeed be the issue. I would be checking out the current going to it and figure out what gets hot and stays cold in operation.
Check out whether there is a bypass. If its internal or external and that it is functioning correctly and situated correctly if external.

Now how does it know that the flow has been impeded?
I would be checking the function of a flow switch of some description that operates or should operate when the pump is running.
I think I will play my joker on that one.

PS FWIW. I'm here to excercise my brain cell and for the sake of the cold and unwashed. Not interested in the money but its nice when I get it right and people send me dark chocolate.
