    Question Error E50 AEG Lavatherm 56740 - How to enter service mode to diagnose further?

    Model Number: 56740
    Brand: other
    Age: 6-10 years

    This has started to happen intermittently. My dryer drum will turn for a couple minutes and then sound like it's struggling to turn the drum. It will eventually stop, display error code E50 and then beep twice every 10 seconds or so. From my search of the internet it sounds as if this is motor related either the physical motor or on the motor section of the PCB.

    Is there a diagnostic mode for this machine that might allow me to further refine where the problem is?

    Thanks.

    I've never heard of that brand. Maybe jeff1 has. Jeff lives and has an appliance shop in Canada, he may know. You can go to Jeff's forum section here: http://www.applianceaid.com/qanda.html

    AEG isn't a Canadian brand either, but it's pretty big in Europe though. The previous owner of my condo liked his expensive European appliances which is good for me for general usage, but it kinda sucks when I have to do repairs. We have one AEG parts supplier here in Canada but their prices are four or five times what I'd pay for a part from Europe even with shipping!

    I'll try Jeff and see if he can help me, though I suspect our smaller market up here might make info even more scarce.

    Viking and Thermador are like that. This might be helpful; All major appliances regardless of brand come with a tech sheet and wiring diagram. The tech sheet has the steps to enter service mode and a list of error codes. It's usually found in an envelope taped to one of the inside panels or in the console. If the machine has had service work done on it before, there's always the chance the last tech took it home with him but most techs are courteous enough to put it back.

    Even though I haven't heard of that brand all dryers basically work the same way. It does sound like a motor issue with your dryer but it's also possible something is keeping it from turning like rollers or glides. Most of the dryer motors I've replaced have the RPM and Amperage rating stamped on the motor label. Check the current draw on the motor. If it's higher than what the rating is, it's bad. It can also be something as simple as cleaning out the motor or lint filter housing.

    I think your starting point should be to take it apart and check for something obvious like a frozen idler pulley or roller. See if the motor shaft turns free with the belt off. Keep in mind there are no parts in a dryer that need lubrication. Do not use any lubricants on the dryer. Steel wool or soap and water for any stuck parts.
