If I open first valve and run hot tap, the pipe goes warm which I believe isn't meant to happen (I do have a loft extension which I've noticed first pipe has a run off then goes up) And then ch light comes on as per pic Edit. After several minutes light has gone off but can still hear boiler...

This thermistor is to the right though? Apologies, I'll blame lack of sleep due to a newborn

Is it this red one on the right with green wiring? Thx!

Ok thx will check that out. If I isolate the heater flow (1st pipe under boiler) issue still persists. If I isolate return flow (last pipe under boiler) the problem seems to go away but obviously no heat to rads. Was just trying to isolate issue. Would that add up to the frost stat thing...

Hello all I've searched the forum for similar but now a bit stuck. My baxi duo tec randomly started turning on the heating over the last few weeks. I've cleaned the heat exchanger and replaced diverter valve and motor and still the same. When I done all this I turned boiler back on and left...

Hi guys So my duo tec boiler is slowly dropping pressure Checked the rads etc for leaks. I've noticed if I turn the red spindle on the prv inside the boiler there seems to be some water escaping between the nuts. I've tried to tighten these up but it makes no difference and still leaks I...

update it was lower bottom element tripping rcd. replaced and is fine but one question when I went to replace the element that goes around the fan there are 3 wires coming from the back. the photo I took only had 2 wires connected to the element so this must have popped of when removing as...

right so still baffled with this disconnected fan and element was already disconnected and still tripped. changed thermal cut off and still tripped changed thermostat from top oven and still tripped a wire goes from bottom thermostat into thermal cut off. then another wire from thermal cut...

thanks will try top oven works fine though so assumed the fault doesn' lay there but worth a try

yes you can access it from inside the oven and goes round the fan I tried with no circular element attached and it still trips When changing temp dial

thanks but this is what I already replaced originally. I've even left the element out and disonnected and it still trips

hmm interesting ok will take another look tonight if i can and see if i can find it. why did it not trip though if i ran the thermostat to the other thermal cut out? or does the bottom thermal cut out connect to this other element you are suggesting. thanks again. edit: sorry which fan...

Thanks thats what i thought otherwise the fan etc at bottom wouldnt work. yes i replaced main oven element and made no difference or do you mean another element? i can see an element at the top of the main oven which i presume is the grill. but even when i dont choose this on the selector...

so I wired the bottom thermostat dial to the top oven thermo cut out as I know top oven works. this didn't trip the electrics and i could turn heat up but as element isnt installed I can't verify it would heat but it didn't trip. only left it on for a few minutes to test. I am going to swap...

hi all need a bit of help! i have a neff oven that has been working fine for 3 years. top oven all works fine. bottom oven I can choose from fan grill etc with the dial but as soon as I change temp from 0 within a few seconds it trips the rcd. I bought a new bottom element and still same...

Thanks, the shower cubicle is On this wall but in the corner and piping is on the other wall so by logic not sure if the shower piping will reach to where the issue is but you never know. Was your wall mark wet / get larger in size?

Thanks for your reply. This wall is not externally facing, its between the en-suite and the bedroom. Sorry should have stated that. a colleague of mine suggested it could be condenstation build up around the radiator pipe from the cold weather when i was on holiday and the heating wasnt on...

Hi all not sure if this is the right subforum to post. i have a loft conversion with en-suite. been fine for years. went on holiday the other week and came back and saw a few inches on the wall the paint had slightly bubbled. i rubbed it and the paint came away, and looked slightly brown...
