Error codes on Worcester Bosch Greenstar boiler

[itm2]

Our WB boiler displayed an error code of "EA" this evening, with the reset button glowing. When I pressed the reset button it restarted, and the display starting counting up from number 19 to 67. The number 67 is now permanently on the display.
Does anyone know what this indicates??
(it was installed about 5 years ago)

The number is its current running temperature and nothing to worry about.

EA is a flame detection problem and if it comes back you will need an engineer's visit.

Thanks. What types of things might cause a flame detection problem?

Lack of adequate servicing is the main cause, but there are a fair few others that will require an RGI to sort out. None are DIY.
