the primary flow switch and micro switches are a common point of failure if both circuits are not working
does the boiler fire up and run straight away and then cut out or does it take a while to spring into life

The hot water starts straight away usually then cuts out
Checked both micro switchs with a meter and they work OK both flow switches seem to move to actuate the microswitches - this is on first fire up after switching off - then after the first cut out it gets erratic and sometimes the pump primary flow switch does not move so the boiler ignors the demand from CH or DHW
Mind you - you may have a point......... The only diaphram that I have not replaced is the primary flow one - maybe that leaking - that would shut the CH & DHW down too...... Will get a new one tomorrow ........ hope its not the £32.00 I paid for the last one...... must be a cheaper alternative - does Baxi or one of the others use the same diaphram?
Thanks for that

Alas, they are not; in fact, they are a lot closer to the bottom, than to the top.
When was the boiler installed?
Can you contact the installer?
Boiler installed in 2002 - think he has retired
Decided on Halstead as they have a good spec and the system seemed simple - it ran OK for a few years - looking at this andother baord seems none of the domestic boilser are reliable?
Might not be the best boiler on the market, but at 7 years old, it should still have a few years left.
Best thing to do is clean the system properly. Plenty of info on the forum on how to flush a system, start with faq

Hope it will last a bit longer
Have tried everything to get the system clean - last year I bottomed the lot! took all the radiators off one at a time and flushed them out with everything I could get, even the power washer (boy that shifted some stuff) and Halstead recommended a rubber mallet banging the rad at the same time
Put them all back - then put in sludge cleaner for a week - then drained again and put in the preventer stuff
When I drained it this time it came out clear - the only other thing I can think of to clean the system is the power flush I keep hearing about - looked on the FAQ and it does not say how to do it (assume you put a water pump onto an upstairs rad and blow everything through - is that correct? if so will buy a pump
Thanks for your suggestion - corrosion seems to be the main problem in any heating system.... what about fitting a filter? or some device to get rid of the limescale?

Anybody any more ideas
What about the thermistors?
Understand you can test them
room temperature 10-12 kohms
heated up 3-4 kohms
Will this give me a reliable test?
What do the thermistors do?
Help appreciated - thanks
