hi guys, new to this but been reading a lot today to find a solution, no joy so here goes, had a late shower last night, heating and water all ok, woke to a cold house this morning, nothing worked, on taking a look the water pressure was below 1, so on searching found it needed to be higher, did that and lights and all came back on, but when i run the water and heating it stayed cold, and a red light indicated something with the temperature, the model is whitestar 29t, year 2005,its a landlord house and he aint answering his phone and i have a young child who is freezing, i have seen many replies to others about resetting, but cannot find a reset button, have switched off at mains and on again, still nothing, sorry to be so long but wanted to cover as much as possible, all help greatly appreciated
