Just text, please

Please could you take a photo of the indicator lights on the control panel, and attach it here.  Then, turn the selector switch to the RESET position, and then back to where it was before.

Sorted it out myself in the end

Presumably you sorted it out by resetting the boiler.

If the pressure drops again, a common cause is a partially open PRV, and often the cause of that is loss of pressure from the expansion vessel, so if you haven't had the boiler serviced recently it might be good to arrange that.
