Going by the diagram it says if the red light blinks you’ve got any issue with the boiler overheating check the over heat stat and replace if necessary.

Overheat stat has continuity???? I assume it’s a make and break stat ?

Update fault is with the pcb..... 3 year old water heater cost of the pcb £500........wtf

where did you get that price from

i get the feeling although you can still buy them that the heater may be obsolete searching on plumbase and wolesley there are no drawings for parts. lots of refubished boards out there though

Wolseley group ...... it can’t be obsolete only 3 years old, the aps is £165 overheat stat £65 and the temp sensors £35 all plus vat ....... absolutely shocking prices...... may have to go with a refurbished board.....
