The appliance has 5 types of fault / information code.
Operating - these codes are displayed in the information option and show normal operation codes as listed in the fault / information code table - these are not an error or fault.
Blocking - these codes are displayed and sometimes temporarily prevent the boiler from operation but auto reset when the condition clears. Sometimes the boiler will appear to operate still but performance may be reduced.
Locking - these fault codes are more serious and require the appliance to be reset by the customer or engineer, the appliance will not operate until reset and sometimes these codes will be remembered even after a power off and then power on again.
Maintenance - these codes do not prevent operation but may reduce the appliances performance and energy efficiency.
Information - these codes do not display automatically they will sometimes display when the service/installer mode is initially activated but may need to be searched for by selecting "current fault" from the information menu, these do not prevent operation but may reduce the appliances performance and energy efficiency.
