Your boiler has temporarily paused because it detected a measurement that was slightly outside its normal limits, and it will try to restart itself automatically once everything settles down.

Monitor it

This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.

Technical description

DIY fix possible

Wait for 10-15 minutes to see if the boiler resets and restarts itselfCheck that your radiators are bled and there is no air in the systemEnsure your boiler pressure is topped up to between 1 and 1.5 bar
