Dealing with a boiler fault can be a frustrating experience, especially when you’re left scratching your head over what the dreaded A22 error code on your Worcester boiler means. But fear not! In this guide, we will walk you through some quick and easy steps to troubleshoot and fix the A22 fault on your boiler, so you can get back to enjoying a warm and cozy home in no time.

Troubleshooting the Dreaded A22 Fault on Your Worcester Boiler

If your Worcester boiler is displaying the A22 error code, the first thing to do is check the pressure gauge. Low water pressure is often the culprit behind this fault, so ensure that the pressure is between 1 and 1.5 bar. If the pressure is too low, you can easily top it up by using the filling loop on your boiler. Simply open the valves and watch the pressure gauge rise to the correct level. Once the pressure is back to normal, reset the boiler and see if the A22 fault has been resolved.

Another common reason for the A22 fault on Worcester boilers is a faulty pump. To check if the pump is the issue, you can listen for any unusual noises coming from the boiler or feel the pump to see if it’s hot to the touch. If the pump is indeed faulty, it may need to be replaced by a professional. However, before calling in the experts, you can try resetting the pump by turning off the power to the boiler for a few minutes and then turning it back on. This simple step might just do the trick and clear the A22 error code.

If the A22 fault persists even after checking the water pressure and pump, it could be due to a more serious issue with the boiler’s electronics or sensors. In this case, it’s best to contact a qualified heating engineer who can diagnose the problem and make any necessary repairs. Trying to fix complex electrical faults on your own can be dangerous and may void your boiler’s warranty, so it’s always best to leave it to the professionals.
