Worcester Bosch Greenstar CDI Conventional - EA error message

Any help will be greatly appreciated although the outcome will likely be calling a Gas Safe chap in.

The EA error message has come on and the boiler has switched off. I have tried holding the reset button in for five seconds and then the boiler fires up, but after a couple of minutes it switches off and the EA error message comes up again.

Any other likely simple fixes for us to try?

Could be a number of things, but I would need to be in front of the boiler to see what is happening.
My bet is flame sensor, but you'll need a GS bod to install it.
