    Linea 28 keeps going to combustion mode error CO

    I haven’t tried that though i am pretty sure it was not in contact with the push button. I have removed the small plastic cover from it to check overnight.

    Linea 28 keeps going to combustion mode error CO

    I have for the first repair but I have bet for the rest. There is another guy coming and he thinks it’s a diverter valve issue and thinks the leak might have damaged the control knob PCB as well. As you rightly said about the “faith being lost” I just need to be sure by getting some information...

    Linea 28 keeps going to combustion mode error CO

    I forgot to mention there was a slight leak after he installed the DHW heat exchanger which was coming from behind the diverted valve, he fixed it after the leak was identified (almost after 30 mins). Could that have damaged the diverted valve and main circuit board again?

    Linea 28 keeps going to combustion mode error CO

    thanks for your kind reply, the original problem was no power to the boiler and the guy suggested the main circuit board had fried and he installed a new one, then no hot water and CH worked fine. Hot water only worked if I twisted the knob for the hot water temperature very slightly and it...

    Linea 28 keeps going to combustion mode error CO

    Sorry for being out of it. The hot water is not working well and the radiators are getting very hot even with the switch turned to hot water only. I have to turn the heating off from the thermostat to stop that from happening or turn the boiler off altogether. when I switch on only hot water...

    Linea 28 keeps going to combustion mode error CO

    So to put the things in order of repair/replacement 1. Main circuit board (everything worked fine after that but the water wasn’t getting very hot and the boiler was cutting out @39 degrees for hot water which then prompted him to change the plate heat exchanger). 2. Domestic hot water heat...

    Linea 28 keeps going to combustion mode error CO

    Thanks for your reply, he did reopen the PCB to see the control knob(I am assuming it’s the black one that sits behind the white cap that can be screwed off). Or is it something else that I should tell him? He pressed the black knob once with a screwdriver and the CO shows up on the screen...

    Linea 28 keeps going to combustion mode error CO

    I have a problem with my linea 28, the engineer just replaced the Domestic hot water heat exchanger and the Main PCB (old one was fried). The PCB was changed first and then it was intermittent cold and hot water, he suggested the domestic hot water heat exchanger be replaced which he did...
