Worcester R25 sloshing water noise and EA code

[Scott.Devereux]

Hi all

I'm new to this sith so please bear with me and apoligises in advance if i mess things up!
I have a Worcester R25 boiler. which has been getting noiser over the last few days and now all I get is an EA error code. There is gas supply. The strange thing is, just before the ignition cycle, when the fan starts, it sounds as though the fan is mixing water! (a bit like a washing machine). then the unit tries to ignite. Previously it was igniting; then it would burn for a short period of time before vibrating/resonating loudly before blowing itself out. Now it doesnt ignite at all.
Does anyone have any Ideas?

Thanks in advance

Scott

check water preasure on gauge refill if necessary

check the condense trap or pipework isnt blocked

sounds like air in the boiler, check the auto air vent cap is loose and the system pressure is around 1 bar when cold
check pump for air loosen the center screw

Check condense isnt blocked or frozen
