Hi , unfortunately i think the boler module is faulty , if you remove it, do you have the link that came with the boiler. This would allow you to have the heating on maually at least
Customer: replied 1 year ago.
Not sure what y mean by link,does this mean i have got to get new reciever
Customer: replied 1 year ago.
Had a plumber install the boiler is there a place on the boiler where he could have left it(the link)
Expert:  Plumberpro replied 1 year ago.
Hi, yes it would mean new boiler module. The link may have been left with the instructions . But you can remove the module from the boiler, and put a link wire from ls to lr to get temporary heating

Removed the module the lead cable attached to the module, unpluged form main board but there are no markings where the pin connected to the board cannot see ls or lr anywhere best leave alone and get new module.
Expert:  Plumberpro replied 1 year ago.
Hi, its the main wiring board . Look where the power cable goes. In there will be the switch live connections . They should be marked ls and lr , live send and live return . Put a link between these two and if the boiler is working ok the heating will come on
