Troubleshooting your Worcester Bosch boiler A21 fault

If you’re seeing the A21 fault on your Worcester Bosch boiler, the first thing you should do is check the water pressure. Low water pressure is a common cause of the A21 fault, so ensure that the pressure gauge is showing at least 1 bar. If the pressure is too low, you can try topping it up yourself by following the instructions in your boiler’s manual. If that doesn’t help, you may need to call a professional to investigate further.

Another common reason for the A21 fault is a faulty sensor. If you suspect this may be the issue, you can try resetting the boiler by turning it off and on again. This simple solution can sometimes reset the sensor and clear the fault. If the fault persists, you may need to contact a qualified engineer to replace the sensor.

If all else fails, the problem may lie with the PCB (printed circuit board) in your boiler. The PCB controls the various functions of the boiler, and if it is faulty, it can cause the A21 fault to appear. In this case, it’s best to leave the repairs to a professional engineer who can diagnose the issue and replace the faulty PCB if necessary.
