H13 is the code to indicate the appliance is due to be serviced, it does not affect the operation of the boiler and so it is recommended to retest the appliance once the reminder has been reset as it may have an additional fault.
Service history should also be checked and appliance serviced per Adapt / TOPs as required.
To reset the service reminder:
Hold down the spanner and OK buttons until "menu 1" is displayed.
Press the up arrow so "menu 2" is displayed and press the ok button.
Press the up arrow until 2.5F is displayed.
Press OK and then adjust the setting to the appropriate time until the next service (12 = 12 months), press OK again and a tick should be displayed to indicate the setting has been changed. Setting it to 0 will disable the reminder.
To return to the main display press the spanner button twice.
