Re: BOSCH SGS09L12GB
Could be problem with pressure chamber/transfer hose too on this one as has metering tank on left hand side and does the usual 1min remaining thing and time altering as insufficiant water to operate diaphram on heater box 💡
Could be open circuit heater element too.
Never had to change a pcb on this one, is located in base at right side in front of heater terminals, nice reliable AKO one if my memory serves me correct??
I think i seen a link on here somewhere about the 1 min thing???
Good luck! 🙂
