Hi all, in case anyone was having similar issues, it’s been sorted. Was the PCB, replaced and all is working fine

Are you local to birmingham, I’ll pay you to come down and sort it?

Hi, I have changed the water pressure sensor the f75 code has gone but the boiler is in this weird loop of going on and off. No codes present.

hi I am not a gas safe engineer, I have already wasted money on 3 call-outs with people giving me different opinions on why it’s not working. I am not willing to spend anymore money. I have a family who I’ve had to move into their grandmothers because it’s just too cold to stay here and I’ve...

Is that when you turn the water temperature knob all the way anti clockwise and then back to desire temp so the green light goes off. Tried this? Still doing the same thing

Hi guys, So yesterday morning I woke up to a f75 error code on my 2006 vaillant boiler ecotec pro 28. After some research I decided to replace the water pressure sensor as the cheapest place to start. So in doing so, I isolated and drained the boiler, fitting new sensors, repressurised the...

Update.. so I turned every radiator on in the house (7 of them) and now the radiator is quite hot at the top to the point it’s giving off heat and Luke warm at the bottom. So the troubled radiator only gets hot if all of the radiators are on, but if I switch off the kitchen, downstairs toilet...

Possibly, you might be right however the water exiting the valves on the pipes have the same pressure as if I were to use the hose pipe in the garden from the mains so if there was obstruction in the pipes I would see a reduction in the pressure of the flow even if by a little no?

Hi wayners, thanks for the reply, could it still be a blocked pipe when I opened both return and flow valves whilst radiator off the wall and had the fill valve open so water could gush out into a bucket? I mean it wouldn’t be impossible to replace the pipes but it would mean having to take up...

Right guys I am quite literally stumped with a constant confused look on my face. So did what I needed to do as advised in my previous thread about flushing the system found here: https://www.diynot.com/diy/threads/flushing-the-central-heating-system.635022/page-2 So after taking the rad in...

Perfect I shall do this. Also do I need to isolate the boiler from the system before I do this?

I see, I will take the rad off the wall again and open the return valve. Should I keep the fill open under the boiler whilst I do this so water continuously comes out the opened return valve?

the radiator in question is in a room on top of the kitchen where the boiler is so the pipework from the boiler to this radiator is probably less than 4m

Sorry I’m not quite sure what you mean by this?

When I took the radiator outside and hosed it… clear water was coming out from the other side

Hi yes, when I removed the rad I opened the return and water shot into a bucket at a pretty decent pressure it only lasted 10 seconds as I’m guessing the pressure in the system dropped rapidly but there was murky water coming out, wasn’t thick and sludgy just dark in colour

Thanks for the reply. The radiators in my system are around 3 years old, even the pipework is around the same age. Can I use my method in question to clean the return and flow pipes only whilst closing off all radiator valves? The problem is I don’t have a magnetic filter on my boiler so im...

Hi guys, New here so nice to meet you all. So to get straight into it I’ve stumbled upon a little issue. I decided to test run my central heating in prep for the winter to come but noticed 1 of my radiators doesn’t seem to be getting hot. Well, it gets warm to the touch but only around the top...
