Hi, I have an AEG detailed below, I’m getting an EH0 error not EHO -I think to do with incoming voltage? Seems odd. Anyway, the drier can run fine once, then fail half way though the next load i.e. hot for some time. I can run the synthetics cycle probably twice before it gives the same error. Once cooled down, maybe 2 hrs I can run with no error. PCB inspection shown no dry or cracked joints. I’ve cleaned the filer as usual, washed out the condenser plates and reached in to remove all extra hard fluff at back. Also removed and cleaned the moisture sensor electrodes and behind them then the hell of it.
What do I do next!?
Thanks.
Mod T65270AC
Prod 916096752 Typ01
Type TC09H65HW
The PCB module case has 916096752(01)there are a whole range of Eh faults all you are getting is the user code . to get the accurate code you would have to put the machine in service mode
one of the codes is EHD ( part of the EH0 range of codes ) this code detects current leakage. Is it possible you have a seal gone that’s allowing moist air into the case ?
Dave
Well I finally worked out the diagnostic mode. Turn to C1 with delay+pause for 5s. Anyway, C10 holds the errors I think and it reported EHE and then I cleared it to E00 by pressing delay. Which seal might have gone?
Thanks.OK, I found the ENV06 service manual that covers my machine (I think -how do I check?). https://www.4mcculloch.co.uk/images/mediator/553/599709900.pdf
Anyway EHE = Incongruence between the safety relay (main board) and safety “sensing” circuit. Test to be performed… Replace the main board and restart the diagnostic cycle to check for further alarms.
So that’s no real help.problem is we don’t know what they mean by safety relay
all they are saying it the safety relay and sensing circuits do not agree ie safety relay is closed but sense circuit think its supposed to be open or vice versacould be as simple as a stuck relay on the board
Dave
OK, so I really need the right manual to find where the safety relays are. 1 on the main PCB and maybe 1 on the front control panel? There’s a Dutch guy who repairs the PCB for this error for 60 EUR. That’s less than half the cost of a new board form AEG/Electrolux but a heck of a lot for a small relay -but he knows which of the four to change!
I had a recent fault with my AEG 61275AC dryer ~2 years old. It displayed error EH0 intermittently (and then the drum stopped) and the fault became more and more frequent. The fault seemed to sometimes come and go when moving the machine, so appeared like a loose connection. Eventually I traced the fault down to hairline cracks in the soldering of a relay very close to the mains inlet on the controller PCBA. I believe this relay is the “safety relay” referred to error code descriptions. I resoldered all six connections to this relay and fault was immediately resolved. So it seems as if ~2 years of operation had caused the hairline solder cracks, and nearly resulted in scrapping the machine. I would suggest always checking the PCBA for soldering problems when there are intermittent error codes; you need a magnifying glass to have a good look. Hope this may help anyone with similar problems.
Good luck. I hope it lasts. I had touched up some poor looking joints previously but don’t think I worked properly… The issue with intermittent faults.
I got a technician out to help and they replaced the main PCB then running an earth leakage test before signing off the job found it surprisingly high. Next they changed the heater element and it was either that or remaking all the connections that finally fixed the machine. Not as conclusive as I was hoping in terms of identifying the cause but I’m back up and running nicely.ewan_mcbellbasher wrote:I had a recent fault with my AEG 61275AC dryer ~2 years old.

I’m trying to troubleshoot this exact problem. Was the hairline crack on the power board PCB (on the side, near the rear of the machine) or the controller board on the front?
If it is the power board PCB, would you be able to identify the “safety relay” on the board (see image)?
good evening I have the same problem and according to your suggestion I resoldered all the relays and now is working fine again thank you…..sorry for my bad english
same pcb as above but electroluxI did look at the PCB using a cell phone camera on full magnification and noticed hairline cracks in the soldering of one of the relays. After resoldering, the dryer functions perfectly (used 4-5 times per week for over a month after repair).
Hi Sigudur, can you help identifying those relays please. Sitting with the exact same board and issue.
Hi Steyn, it was the horizontal Omron chip on the right edge of the board in the image above, between the two sockets. It has six pins on the back and I noticed hairline cracks in all solders. They were not obvious. I could only see them with some magnification and the chip was not loose or anything. I resoldered all six of the pins to be sure and the dryer is still going strong.
