Worcester Greenstar boiler: EA error code
Discussion
Our WB Greenstar Compact is just over a year old and was serviced around two months ago. Before that its been faultless, as you might expect.
Since the service we've been getting EA 227 error with increasing frequency. The installer came to check things and determined the gas regulator on the meter was faulty. This was replaced and everything has been fine for the last month.
Unfortunately, the error is back today which coincidentally is a cold, wet, blustery day which seems to fit the pattern.
I suppose a call to Worcester is the next step.

I have a Worcester 25 CDi and have the same "EA" issue every autumn, boiler fails with an EA error code sometime is fires up and works with a couple or resets but other times not. I have tried turning the boiler of for a few hours and that sometimes works.
I have had loads of different so called specialist look at the boiler and loads of parts replaced but it is the same every year, as soon as the weather turns damp or foggy or very humid it does its EA trick again.
This morning the house is cold and i have done about 20 resets and this piece of rubbish will not work.
Surly Worcester must know what the problem is, think i am going to call them to see if i can get a fixed price call out and repair.
Very frustrated and cold.

Fixed price out of warranty visit? Be prepared to remortgage if you want a Worcester employee! You would be better to look at their accredited list of install and service engineers - if you're a CF, SA or NP postcode, you might even find me.I have had loads of different so called specialist look at the boiler and loads of parts replaced but it is the same every year, as soon as the weather turns damp or foggy or very humid it does its EA trick again.

Thank you for your post, unfortunately in "DA" postcode but getting to a point when i would pay a lot to get it fix but not to have someone come around and throw parts at it. I need someone who actually knows what the root cause is and fix that.
My boiler has had all the parts listed in this thread but still mucks about every autumn.

PM me your serial number and GC number (to determine age), I know a good engineer based in Sidcup who is on ze list also.My boiler has had all the parts listed in this thread but still mucks about every autumn.
We're now getting ea 227 every morning. It also now needs a couple of resets before it behaves.
We had our mid-December call out from WB moved forward to today, but unfortunately they arrived when my wife was out on the school run, although the notes on file had this down as a time to avoid. They also only telephoned 8 minutes before arriving (we were told 30 minutes notice is given) and they only waited 4 minutes before sodding off. At the time one of their customer support representatives was trying to contact the engineer but he wouldn't answer his phone and later claimed to be too far away to return - the cctv shows otherwise!
Anyway, we're now booked in for next Tuesday which is the new slot they have for us!
Not hugely impressed seeing as I bought WB based on reliability and support quality.

I found this great forum when I googled " why does my Worcester Bosch boiler sometimes fail to ignite with an EA227 error code ". I have had the boiler nearly 3 years now and this summer / Autumn it started doing this. I have had WB round but the problem is still occurring from time to time. I get the impression from this that no one really knows why this happens, though you would have thought WB would know. It's not every time I use it but I'm pleased in a way it's not just me. It seems even if parts are replaced it still doesn't fix it so we may just have to live with it ( or get another boiler! )
Just to update, WB replaced everything they thought might be causing the issue (I don't have a list but it was five parts - ignition switch, regulator, some flap, etc). It's been fine since.
Friendly engineer, who called the night before to give us a time and turned up when he said he would.

Hi all,
First of all sorry for my bad english.
I've been suffering the EA issue for the last weeks with my Cerapur Comfort ZWBC25-2C 23S3700 ( Worcester Greenstar name for east Europe market )
The boiler is 5 years old, an never has been revised. The error appears almost allways when heating is on, and rarely with hot water only. EA error disapears when reset but last week it occurs every 5/10 minutes.
I've clean the siphon that was almost clean and revised smoke tube. In my house temperature rarely goes bellow 0ºC and siphon never freezes.
When a technical arrives after only 5 minues and 30€ of job his diagnostics is bad gas regulator (250€) or bad moterboard (300€) costs, only pieces. Could be one of them, two or other thing. Zero guarantee if fail when any of this elements are replaced.
With this info and the great quality of technical service y decided disassemble fan, burner electrodes, and anything item possible. Burner electrodes are almost clean with a little rust in. I clean with a very thin sandpaper.
When I put the fan in his place I can observe that rubber tube that joins gas valve and fan is old, dry and with some big cracks on it. I glued the cracks and covered the entire tube with sealant tape for test it.
After one complete day it works perfectly with not a single fail and burner at hight power.
It's an issue easy to test before start changing any other more expensive piece. New original replacement cost is only 12€.
I hope this info could help someone.

Ok guys! I've only registered on this forum because I have struggled with this problem too long and even had a technician come and not be able to solve this problem!
Worcester Bosch 30CDi Classic System
I think I have, so bare with me while I talk about the symptoms I faced.
The boiler in the winter months would not fire up and show me the dreaded EA code, usually I found this happened on days colder than +7C, it would happen most of the time when the boiler sat idle over night and then in the morning I would wake up to a frozen cold house, shivering in the utility room trying to reset it while I swore.
Sometimes it would reset after one reset, sometimes it would take an hour. The main thing I noticed with all this was the colder it was, the more chance of it tripping especially if the boiler cooled off for too long. I also found it was harder to reset in colder temperature.
When the technician came and serviced it he said he saw the fault but couldn't reproduce it that day, checked everything and all seemed OK.
I have a pressurised water system in the house and I had a fault with that, the pressure vessel on that had 0 bar pressure, so i closed the valve and ran all the hot water from the tank, once it was all out i read the pressure of 0 bar on my bike pump and pumped it up to 3bar to equal my cold water pressure! that was solved.....now....
I thought maybe i should check the vessel in my boiler, when I emptied the system pressure from one of my radiators, surprise surprise!
Expansion vessel pressure = 0 bar
I pumped it up to 1.2bar = to what we want in the system, closed the valve and radiator. Topped up the system up to 1.5bar water pressure and it fired up instantly!
If you have the same problems as me, follow those steps and I'm sure you will resolve the EA $£%@£^ code!
1. Power off Boiler and controls
2. Find the lowest radiator and bleed it until boiler pressure shows 0
3. take off the front of the boiler, 2 screws front bottom and one push clip on top, pull it off towards you.
4. Expansion vessel is top left, burgundy colour with a car tyre valve
5. Connect Bike pump or hand pump and pump up to show 1.2 bar on your bike pump.
6. close radiator bleed, disconnect bike pump and put valve cover back on
7. Top up system pressure using water up to 1.5bar + -
8. Turn on boiler, turn on control for heat and watch her fire up!
9. Put cover of boiler back on.
Please only do this if you feel comfortable with working on something so complicated.
Hope this helps someone!

It's highly unlikely that a flat expansion vessel will cause the EA fault code. Also worth noting that removing the case on a Worcester Greenstar is classed as 'gas work' and shouldn't be carried out by a non competent person. Not that there is much damage you can do, just worth mentioning.Worcester Bosch 30CDi Classic System

I attended a Worcester HE Combi today, which has the same heat exchanger and similar burner set up as the CDI Greenstar. It was locked out on an EA fault code, it fired up straight away and ran fine. I performed a flue gas analysis on it just out of interest. Factory settings are supposed to be 8.8% CO2 on minimum rate and 9.2% CO2 on max.
Max was 9.6% and min was 11.0%! After adjusting the max setting, the minimum setting was erratic and fluctuating between 6 and 11%, it took a bit of adjustment, but finally got it down to the correct level. I've a feeling the gas valve was so out of adjustment that it was locking out on minimum rate. Which would tie into why a lot of people see this fault after the heating has been on for a while.
It's worth asking your 'engineer' to check the flue gas readings on minimum just to rule it out.
There is also a growing trend for the gasket between the electrode plate and heat exchanger to fail and cause heat damage to the boiler on the CDIs, ask him/her to give it a once over. It can do quite a bit of damage if left unnoticed.
Hi Guys, just woke up to a cold house, EA code, I pressed the reset button and it fired and went into its cycle. After around 15 mins it coded again,and will not restart, after some research it says that the condensation trap can get blocked, I’ve disconnected it from the waste and blew back up through it, I felt something suddenly unblock and water came rushing back out, boiler is now up and running after it’s completed it’s cycle. Clearly it needs a proper dismantle and clear out, but it seems to be my problem. Worth a try for free!

I experienced the EA 227 issue during the recent big freeze. Following some earlier comments I went outside and checked the condensation outflow (the pipe which takes condensation dripping out of the bottom of the boiler) and found the end was frozen. I think this caused the water to back up into the boiler where there's a safety check to ensure the condensation is getting removed correctly.
Looking into the bottom of the boiler I could see a small transparent plastic tank on the left hand side which has a small cap/plug at the bottom. Removing (or at least opening it a bit) allowed the built up water to drain from the mini tank and the boiler then started up after resetting or turning off then on.
I then left the cap slightly off to allow the condensation to continue coming out as the boiler was running. I'll put some lagging on the condensation outflow to hopefully stop this freezing again.
Hopefully someone else finds this helpful in the freezing weather

PH to the rescue! I came home tonight to a cold house, and had this code, so removed the cap on the bottom of the tank and let about 2 litres of water out, now the boiler is running fine.Looking into the bottom of the boiler I could see a small transparent plastic tank on the left hand side which has a small cap/plug at the bottom.

My boiler is in the loft and the condensation waste pipe goes though the wall into the top of the soil pipe which is about 18 foot in the air, so gets a bit of wind chill. I`ll go up into the loft and drain it again in a bit.
Thanks for passing on this info, and have a virtual pint.
Long running saga with EA 227 on a 3 year old Worcester 32CDi.
Recurrent episodes for past 2 months. Have had two visits by Worcester engineers who have done their best:
1. cleaned the condensate trap
2. replaced ignition leads
3. replaced gas valve
4, replaced transformer.
There are three odd things that we've noticed:
1. The EA 227 usually triggers at night, after the CH has been on for a while, and a lot of Hot Water used for washing up dishes, and Showers.
2. Immediate Reset is usually unsuccessful, but after leaving for an hour, a partial trigger is possible with the boiler active, lots of noisy rumbling and gurgling for 30 mins. However, boiler can only manage 50 C and is not able to reach target temperature of 64C. It then goes to EA 227 again after about 30 mins.
3. Reset, and then leave the boiler alone overnight for 8 hours (without calling for CH or HW). The programmer is often then able to get the CH working in the morning.
Can't help but think that something accumulates with heavy use in the evenings that triggers EA 227. Is it plausible that the overnight rest then allows whatever it is to drain off?

Hi All
I have a Greenstar 37CDI five years old (And the dreaded EA for 8 months)
Had it serviced, still there
Seems to happen more first thing in the morning but does do it in the day as well, heating off no water being used just wake up to EA. Not connected with weather as it has been doing it since the snow to the heatwave we have now.
In the morning it takes many resets to work, left until mid morning only one reset and it works. We also have the long vibrating noise going more high pitched until it stops usually about 8 to 10 seconds. This is also intermittent but mainly 5 in the morning ish.
Not sure if these two issue are related.
Not sure where to go now call WB out at £350 or stick with normal plumber engineers, although they have not seen it error code could not find an issue when servicing it.
One engineer in passing said a pressure reducer might help, not sure if that is for the water or Gas though.
Any help would be appreciated.

Hi All, I have the Worcester 36cdi compact. I had it on trial before it physically launched so once the final model came out Worcester themselves replaced it for the final production version.
A few years after it wouldn't light properly. Worcester came out and replaced the electrodes under warranty. Apparently they are slightly less chunky than the standard boiler and because they are orientated sideways gravity had warped them slightly out of optimal position. He showed me them and it was visually noticeable.
He replaced it and it worked perfectly. The chap from Worcester said his Dad was one of the chief engineers so he was going to report this design issue to him.
Anyway, it's started not firing again (error 227) so I'm wondering whether to buy the replacement part and get a gas safe engineer to replace it.
Anyone know if this is now a known fault with this boiler?
Cheers
Nick
