got no heating or hotwater!!

[Billy Bob Bob]

no ignition taking place have you a multi meter and clear on basic electrics?

 

[no heating]

no multi meter sadly. has been running for a couple of hours but keeps going to flame failure then completely locks out. went thru the fault finding flow chart which mentioned the safety themostat which i reset (possibly!!) and it ran after that. now it's died again......

 

[Billy Bob Bob]

try resetting it again there could be a few possibiltys in regards to over heating could be pump weak,gas pressures to high or corrosion one thing you can try>take the filter out of the return(22mm pipe rh side) turn the isolation valve off theres a mesh filter in under the cap on the front of valve there which can block with crap,clean it re turn on iso and try the boiler,bear in mind the filter could be in the flow if the fitter cocked up valves try this report back

 

[no heating]

tried to take out the filter with all isolaters turned off and the system started draining!! is it safe/advisable to bypass the safety stat to test if thats the problem?

 

[Billy Bob Bob]

no dont bypass it could fracture a joint,this is a very good boiler(so dont be rail roaded into replacing it) you need to call a gsr or be quick and get the filter out to check it

 

[no heating]

gonna try the filter again, is it normal for the system to remain pressurised with all the isolaters shut??

 

[no heating]

got it out in the end and its clean. thanks for all your help gasman
