I have the halsteds finest gold combie boiler,with hot water problems?

My halstead finest gold is not giving my any hot water, it only comes out luke warm, I have had a new p.c.b board fitted, a micro switch, and also something called a thermistor,but all of this has failed, has anybody had the same problem, and if so how did you reslove it.please!!

done
take out the venturi its attached to the clear pvc pipes from the air proving switch at the top of the boiler, it will have a small amount of calcification on it, clean/scrape this off and replace, it worked for me ??

The answer to my problem was the diverter valve diaphram, it may well pay you to try his before you go through the whole of the parts list like I have

Yes if fact the more you turn the hot tap on the colder it get`s
