If it is an Alpha boiler, it will most likely be low pressure. If the pressure keeps dropping when heating is on then the boiler will require a diagnostics to be carried out by a gas safe engineer.

You need an engineer to diagnose the underlying fault on your boiler. This code usually means the boiler is over heating. Let me know if you would like me to attend.

An E10 error on a boiler indicates low system water pressure. To fix this, you need to repressurize the system by using the filling loop to add water, aiming for a pressure between (1) and (1.5) bar. If the problem persists after repressurizing, there may be a leak or a fault with the pump, and you should contact a qualified engineer

You need to top up the pressure of the boiler via the filling loop.
