Got a Baxi 80 E Combi, Central Heating is perfect but NO hot water. The Hot Water neon does not illuminate whatever mode i put the Boiler in.
Any Ieas ? Ive been told it may be the PCB but people sometimes tell you these things to 'Bump the Price up'
Hope someone can assist,

it is the hot water dif valve and you can check by releasing the clip that holds the micro switch in place you will see a pin that is meant to move out when the hot water is in flow about quater inch you will find yours may just move about 2 mm so pin does not hit micro switch easy job good luck
thanks john

Will keep looking anyway, see what i can find.

Let me know if you find anything in the meantime
