Is it the boiler circuit side of the plate that clogs or the DHW?

Thanks. Yes it flashes just for a second nothing more as is it shuts down, then the 70 light stops flashing and the ignition sequence starts and the boiler fires up. Then as the temperature of the DHW rises, it reaches a certain point and it shuts off/restarts again

My guess is that it would go open circuit momentarily when it gets to a certain temperature, causing the boiler to think it's overheated and shut down for a second. Have I got that right?

Hi all, Wondering if someone can help... DHW on my ageing baxi 105e (not HE) is cycling. Gets nice and hot, then after a few minutes the temp lights go out, the 70 degree fault light flashes once indicating a DHW temperature fault, the pump and burner (if it's lit at that particular time)...

Ok. I'll see how it looks when I'm up to my ears in bits. Thanks. I'll report back.

Thanks gas112. Im thinking it's the diverter valve. I've isolated the Ch flow and ran the hot tap. The tap runs hotter and the boiler cct doesn't doesn't overheat and shut down so there's decent flow through the plate. It's soft water here. We don't have lime scale at all.

Ahh right. I see thanks. Is the water Venturi in the brass assembly on the right near the prv? That failing would cause the symptom of the Ch flow getting hot when running the bath? If that's the one I'm thinking of, I just need to isolate the supply do I? Shuttle. Now I know what it's...

Thanks Ian. I don't want to change the bypass valve really (although the kit comes with a new one including the brass housing) but to get to the rear most plunger and spring I need to remove the bypass brass section. To remove that I need remove the copper bypass pipe that is held in with the...

Thanks guys. I'm a bit confused now.... The way I see it I need to remove the bypass valve to replace one of the valve plungers. The bypass valve is on the back of the unit and so the whole lot has to come out doesn't it? I though there were two plungers that act upon each other. One comes out...

Also just thought of another question whilst waiting for kit to arrive. What's the best way of disconnecting removing the valve? I know I have to undo the pipe from the main heat exchanger on the right, the Ch flow pipe underneath and the sensing pipes. Also the clip in bypass pipe had to come...

Hi folks. I'm after some advice if possible. My baxi 105e seems to have a sticking diverter valve. C/h flow pipe is getting hot when running DHW. I've ordered the kit to refurb the valve and know I have to drain the boiler before I remove said valve..... I also know I will have to isolate the...

Pressure seems ok. Flow could be better. Ok with one outlet open but open a second and it drops noticably.

Thanks denso

Hi all Considering replacing my lead service pipe which runs from street stoptap down side of house underground and enters up through kitchen floor under the sink at the rear of house where it splits after the stop cock to the kitchen tap nearest and up the wall into the bathroom upstairs...

Much obliged.
