Observation:
Fault codes A21 - A28 / A61 - A64 refer to faults with Worcester external
comfort or sense controls fitted to the appliance EMS.
Most common problems can be resolved by checking the batteries and resetting the wireless signal.
Refer to the manual for specific instructions for each type of control.
(Manuals are available on Worcester website under "Boiler Controls")
Does replacing the batteries and / or resetting the wireless signal clear the fault code?
Note:
If no controls are fitted to the appliance EMS connections then select "no controls fitted" below.
