Troubleshooting the A03 Fault on Your Vokera Boiler

Another common cause of the A03 fault on Vokera boilers is a faulty pump or circulation issue. If you’ve checked the water pressure and the fault persists, it may be worth checking the pump for any blockages or signs of damage. You can also try bleeding your radiators to ensure that there are no airlocks causing circulation problems. Taking these simple steps can often rectify the A03 fault and get your boiler back to its reliable self in no time.

If all else fails and the A03 fault on your Vokera boiler persists, it’s always best to seek help from a qualified heating engineer. They will have the expertise and tools needed to diagnose and fix the issue quickly and efficiently.
