- Has your Vaillant boiler stopped working and the display now say "F28 or F29 F54"
In this video I show you how to diagnose the boiler.
Also what might be causing the problem.
This video is aimed to gas engineers and trainee engineers under direct supervision.
Hello mate, had this exact same fault sequence. Changed the gas valve & all good for a couple of months, then started throwing the same faults again but managed to clear it and all good at the mo. 🤞. Seems to be common problem on these... Pcb next or scrapping tbh 😂
I would say buy a refurbished PCB from eBay and change it if it gives you the fault again. These are very reliable boilers so worth keeping tbh.
Probably the most comprehensive explanation I gave come across as you deal with both gas and electric issues...well done.
Keep up the standard
This fault was due to the gas valve and is a known design fault on the vaillants pros and plus which was kept quiet for many years.
