Hi!

Why the domestic hot water doesn't heat up when it's only selected to do it, being the temperature of the heating output of 65º, and consequently the boiler turns off

Can anybody help me in this matter, pls?

Any ideas are welcome

Thanks

Bon dia.

That seems to be a slightly different model name than we have here in the UK however its probably pretty similar to an ordinary 242.

I dont really understand what you are asking but wonder if the diverter valve has failed?

Was thinking blocked dhw heat exchanger myself, but it's anyone's guess!
