i too am having daily visits from british gas my boiler a worcester RD 350 also keeps going into EA mode, it works fine for up to 24hours and the goes into this code reset it and its ok for a while before it does it again , temperture way above freezing so not frozen pipes . they have drained and cleaned it out reset the co2 emissions gas pressure seems within limits i'm beginning to feel that they are doing everything not to have to change parts can anyone give me any idea what the next step should be as i will kick up a fuss if they try and buff me off again not a problem with the call outs as i have homecare but its a real pain having to keep trying to get time off of work .

it gets worse after todays british gas visit it sounds like its rumbling and shuddering it goes through a couple of cycles alternating between the temperture going up to 40 then back down and it keeps showing p1 p2 p3 p5 p1 then the temperture rises again and it alternates through this cycle again and then dies with ea code flashing have turned it off am now so fed up with it all , got the gas men booked for thursday morning at the rate were going it may obsolete before i get it fixed but thanks for you suggestion have left details of worcester bosch technical help line number for them , think its time to start stamping my feet this is getting silly how many visits should it take to sort out a boiler
