All the surface mount components look intact. Looks perhaps like one wire completely missing? as well as several damaged.
Interesting how repairable it might be considered to be, and who would want to attempt that. Need a quick way to tell if the circuit boards might be damaged before spending too long on it. I'm totally non qualified but I'd want to check the chassis earth all present and correct just as a first step. So interesting to me as a rank amateur (I wouldn't go near a boiler or gas) how much electrical training a gas engineer gets (and acquires).
Yes correct guys had a furry visitor no evidence of him other than the chewing and poop 🤣🤣 PCB is shorted out black and scorched on the back £207 for a board no choice but to go for it .
Yes bud do it every year pictures are from a 2019 full strip down clean and service gets done like that every 3 years , and a interim clean and check in between , was booked to remove old shower doors and fit new ones there yesterday when I got the call "I've no hot water"a new PCB is on order and few wiring repairs and 🤞 hope she comes back to life 😉
Nice to see someone who can actually be bothered to treat an old boiler with some respect rather than just give it short shrift because it's old anyway.
0.0001 is the flue gas co/co2 ratio it tells us how well the boiler is burning, the lower the reading the better the combustion, less carbon monoxide is produced and put into the atmosphere 6ppm is very low for a old boiler and goes to show what can be achieved . Kop
