heads up. it was plate heat exchanger. symptoms sounded like expansion vessel . live and learn

Ive isolated heat exchanger .it has a valve just before exchanger on water inlet . Had heating on for 2 hours and its steady at 1.2 bar .I think its heat exchanger ! live and learn . Thanks for all the replies

Hi charged to 1bar before fitting. i wonder if it could be heat exchanger ?

Hi yes did that this morning

Hi all odd one here. Firebird enviromax boiler . was gaining pressure up tp 3 bar . to point where safety valve was opening. Fitted new expansion vessel 12 litre same as original. Still happening . dropped pressure back to 1bar via safety valve still keeps rising Thought maybe...

I replaced cont box then it went to purge mode. so cont box was def faulty.(my old one did nothing) i then disconnected my original pc and it fired then locked out indicating bad pc. went and got a,new one but bought digital one by mistake. have analogue one coming tomorrow from amazon...

there are 2 photo cells the old one is anologue. it goes with rdb cont box with red reset button (mine) the later box uses a digital pc . looks identical but doesnt work with older box. the new box has a clear reset button .

thanks all . school boy error. new pc is digital. my old one is analogue! new one coming tomorrow. watch this space. going to have to be a cold shower today .3 days is enough !!

well kind of making progress! fitted new box . just purges constantly no spark or flame . pulled photo cell . fires then cuts out . so looks like maybe the old control box took out the photo cell maybe ? . anyway went and collected a photocell from local shop looks the same but fires then...

replaced cap. still dead! waiting for new control box to arrive

ive got a,new cap coming as its definitely ou of spec. we shall see. cheers guys

ive just switched it on with pc disconnected still dead :(

Hi it doesnt even attempt to fire its totally dead . is it still valid to to the photo cell test .

correction! just realised my fluke meter has a capacitance setting! its reading 2.7uf. it should be 4.5. would that cause motor to not run ?

thanks again. ive checked cap with my digital meter. not as good as using a needle type .but seems to be checking out ok .
