The Platinum Combi manual groups these two together: either one means the primary water or the flue system has overheated and the boiler has shut down. Low system pressure can starve the boiler of water, so that's the one thing worth checking yourself.

Safety first: never take the casing off a gas boiler. If you smell gas, open windows, don't use light switches, turn the gas off at the meter if you can and call your gas emergency number from outside. A carbon monoxide alarm going off means the same: switch the boiler off, get fresh air and call.

How to fix Baxi E110 / E130

  1. Check the pressure

    If the gauge is under 1 bar, top up following your user guide before trying anything else.

  2. Let it cool, then reset

    Give the boiler time to cool, then turn the selector to the reset position and hold it for at least 5 seconds.

When to call a technician

If the boiler won't relight or the code returns, contact your installer or a Gas Safe engineer and stop resetting it. Any smell of fumes indoors or a carbon monoxide alarm means switching off, opening windows and getting everyone outside.
