Your boiler is simply displaying its current water pressure rather than indicating a fault.

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

Water pressure in bar.

DIY fix possible

Check the pressure gauge on the front display against the manufacturer's recommended range (usually 1.0 to 1.5 bar).If the pressure is within the green zone, no action is required.If it is outside the recommended range, use the external filling loop to adjust the water pressure accordingly.
