Worchester Bosch E9 Error - It's not the boiler !

[vern]

I hate to admit I am wrong, but Vern I reckon you were right about the boiler as well. Obviuos when you think about that one
So do I assume the hot water setting has no effect on my boiler, or should I set this the same?

Thanks

Yes pal, 1A is the only KW power setting as yours is not a combi, altering 1B will do nothing, as the code plug on the mother board stops this for obvious reasons

Does 1b alter the output if you had the diverter valve kit fitted do you know vern.

Cant fit div valve on 40 CDi Roger as conventional only, you can on 30 cdi system though............

Ahh ok, don't tend to use them so was unsure.

E9 error, I would be considering changing the heat cell mate. The primary flow sensor should cut the boiler out we'll before the overheat stat cuts in.

if you have surface thermometer or temp robe on your gas analyser tape or hold it onto the heat cell where the overheat stat is. If your getting a reading of 100 degree plus but the temp is displaying lower than 80 degrees on the boiler chances are its the heat cell.

Gas analyser?!?

 

[MR RIGSBY]

Gas analyser?!?

Yes, ie your flue gas analyser, Kane/telegan etc.

Most can measure surface temperature

 

[Howsie]

Most DIY'es don't have one though

There are two overheat stats, flue and Heat Exchanger. Exactly where would you take the reading?
I'll be using infrared thermometer.

unfortunately thats where the advice stops.

this forum will not tollerate any advice to d..i..y boiler repairs!.

otherwise this thread/members will be removed unless in the private gas section, please stick to the rules of the forum.

thank you,
