Vaillant Eco Tec Pro 28 fault.

[RayW]

Over the last couple of weeks my boiler has started to throw the occasional S.54 and F.64 codes. I know when its happened because the hot taps run cold.
The whole system is 8 years old and has been serviced every other year.
Normal service is resumed by pressing the reset button.
The question is 1. do nothing but keep pressing reset. 2..call Vaillant for £285 fixed price repair. 3... try to find local (NR30) Vaillant expert for repair.
Advice welcome.

Just googled your fault codes.
Don't go for the fixed price repair.
Doesn't seem to be an expensive, major or terribly involved repair.
Find someone local

Use someone local if they can attend and get the parts.
