My Worcester Greenstar burner goes out after a few seconds

Customer Question

My Worcester Greenstar burner goes out after a few seconds when firing up from cold. Error code EA flashes on, indicating burner not lit. It will fire up again if error button pressed but will shut down and show error code again. Each time this is done the temperature gauge rises a few degrees. After about 3 or 4 cycles the burner will stay lit and boiler will function normally and that seems to be when the temperature reaches about 30C. I have replaced the pump to rule that out. Boiler had been functioning well for years before this problem. I can 'coax' the boiler to work every morning and have done so for seven days in a row now. There must be a fault but I can't figure out what.

Hi Good morning,
when the unit is on, how does it sound before it fails, also any excess smoke?
Also do you have to reset the control to get it back on?
Thank you

Good morning. There is a sound of the burner declining in intensity.There is no knocking.No excess smoke.

Expert:  Michael replied 3 years ago.
Hi Max, thank you for that information.
this is a likely a bad nozzle or regulator. Whats happening is that its clogged or restricted and eventually it will go into shut down because the sensor sees that the flame isn't normal.
The best way to handle this is with a service technician doing a professional cleaning, that will solve the problem;-)

I could do this, and have the manual telling me what to do. I wonder if I should get a heating engineer in though to test the exhaust gases and all that stuff that's described in the manual. Or should I give a good clean out. and see what happens.

Expert:  Michael replied 3 years ago.
Hi Max Thanks, I would get a tech because as you say you need to know if the exhaust is venting properly. Also if the unit hasn't had a professional cleaning in 2 years or more its a good bet it needs one;-)
But I will be here for you.
Please rate kindly so I can set free follow ups for you in case I can help further.
Thank you Max.
