Yeah. Chuck it out and go find a well cared for 30 year old plain and simple boiler that isn't packed out with unreliable tech s**te like all the modern ones are plagued with. HTH.
Agreed. But don't forget you will have to add a DHW storage tank.

Quite possibly the domestic hot water heat exchanger is fouled up with limescale, or, the worst case, the main heat exchanger is fouled up with iron oxide. The best case scenario is a temperature sensor not working correctly,
But my money would be on one of the heat exchangers needing cleaning/replacing.
The flow sensing mechanism may also have a problem if the boiler is not sensing and lighting when required.
