how can i fix my worcester bosch gas boiler?
The reset button is flashing red every second and the blue light every 2 seconds?

We have a manuel stating dt20 programmer for greenstar 1 and greenstar si models but it does not give any help on this problem?

We are not even sure of the actual models name?

No heating or hot water, very bad indeed, please help!
