What to do if my IDEAL ESPRIT 2 24 Boiler display shows ‘HHHHH:::::AAAAA ’ (flashing)?
- MMichael FisherJul 30, 2025
If your IDEAL Boiler displays ‘HHHHH:::::AAAAA ’ (flashing) and isn't working for central heating or hot water, first check that the pressure gauge on the boiler shows at least 1 bar. If it doesn't, repressurize it to 1 bar using the filling loop. After doing so, turn off the tap on the filling loop, then switch the boiler off and back on to reset it. If you can't do this, or the pressure continues to drop, contact your installer. Also, check if all radiators have thermostatic radiator valves fitted; if they do, contact your installer.
