Hi All,
Back in June our tumble dyer (model code 91609270400) started stopping mid-program with the door opening and E50 flashing in the display. It was an intermittent problem. My wife cleaned out the filters and condenser and after a while it seemd OK, but has started up again.Based on this forum and other searches I found out that this is an Electrolux machine with an EDR2000 panel and the code E50 is just a user code. The detailed error code is E51 which means motor triac or motor circuit I believe.
I already changed the motor capacitor as that was a cheap simple job, but didn’t help. I have now removed the panel and replaced the Triac with a new one from RS components.
I thought all would be well, but it’s still doing the same fault. I am therefore thinking either there is still a problem on the main board, or something wrong with the motor.
The board is about £136 to replace and the motor about £150. I am wondering if it’s worth replacing the board or not – basically I don’t want to do both parts as might as well get a new machine.
I am wondering what can really go wrong with the motor and so thinking it’s probably not that, but is the main board.
However, I would like some advice – is it possible the fault is indeed with the motor. Is there anything else I can check to establish which part is faulty ?
Thanks a lot for any advice.
Re: JLTDC05 intermittent fault E51
I’m sure the triac you replaced was intact was it? When they fail they overheat and blow their top. Therefore I doubt that was the problem TBH. What could be your problem is the thermal trip within the motor windings? That would also give the same error code. The only way to confirm that theory is to immediately check the motor windings at the point it fails.
HTH?

Hi Martin,
Thanks for reply. Yes, it looked quite intact as you say.As I write now, it’s been running happily for the past 2.5 hrs so it’s quite puzzling.
If I understand what you’re saying about the motor it’s that there is a thermal cut out which might trip and then reset when it cools. The motor resistance would be infinite whilst the cut out was tripped?
Will be hard to measure that I guess.
Not sure how likely that would be though as when the fault occurs, it will go again immediately just by turning the selector off and on again. So unless the thermal trip is only happening for a really short time I’m not sure.
thanks for help anyway !

Thought so.

Very!

Infinite yes.

We can now rule out the motor’s thermal trip then now. 🙁
Intermittent faults like this almost impossible to diagnose. Error codes also are spurious in nature and act only as a possible guide as to the fault. I can only suggest your next move would be to check all the terminal connections to the main circuit board. Clean the PCB tracks and squeeze the crimped connectors a little to ensure a tight contact.
HTH? 😀
Re: JLTDC05 intermittent fault E51
OK thanks again.
Just watched it now and it stopped in front of me. The drum had been turning one way then didn’t turn the other way, paused a bit and then started flashing E50 (but bizarrely not opening the door) so I am not thinking maybe it is the capacitor after all. The one I replaced it with was a 8uf from Maplin, but perhaps it’s a bit duff.
Re: JLTDC05 intermittent fault E51
I couldn’t rule the capacitor out from here. Though when the motor starts to turn there should be no delay, no hum, no hesitation coming from it at all. Especially the pause between alternate rotations as if the delay is too long then the E51 error will show. The reason being that all the while the motor stops the heater is still operating. The motor incorporates the fan and any pause would then cause the heater to overheat due to the fan not working. If you catch my drift? 😉
Re: JLTDC05 intermittent fault E51
A bit more information –
I ran the test programs and the drum turns fine on the setting 4 – ie anticlockwise rotation, but on 3 it just makes a clunk as if it is starting to turn but doesn’t and then repeats this every second or so.
Would this suggest more the motor or PCB ?
Could I swap the wires to the motor to check if this reverses the behaviour (i.e. works on program 3 but not on 4) ?
Re: JLTDC05 intermittent fault E51
Fearing the worst, I have also been looking at new dryer options. Ours gets a lot of use, probably average 1.7 loads per day 😯 . I was thinking a heat pump dryer might pay for itself fairly quickly, but not sure how reliable they are as there is another thing to go wrong with them (thinking of air con topups on cars, etc).
However, just seen John Lewis have a “Black Friday” special today only with £150 off their JLTDH17 model. This makes it £450 for an 8Kg heat pump dryer. I’m thinking maybe this is too good a deal to ignore, especially if I’m looking at £150 for a motor or PCB to keep the current one going.
I guess this is another Electrolux model underneath. £60 to top up the warranty to 5 years. The more I think about it the more I’m talking myself into it rather than spend rest of today kneeling beside the existing one scratching my head 😀
Re: JLTDC05 intermittent fault E51
Sounds like the PCB is the culprit. If you buy a heat pump dryer be sure and get a 5 year guarantee as there’s lots to go wrong inside.
Re: JLTDC05 intermittent fault E51
Yes, I think so. When I removed the existing Triac I damaged the board a bit as it lifted up the pad that the Triac gate leg sat on.
I tried to repair this with silver conductive paint, but wasn’t sure exactly where it was supposed to connect to so I might have messed things up.Anyway, have ordered the JL dryer with a 5 year warranty.
Thanks for your help and advice Martin.
