    Default KDTE104DSS0 KitchenAid Dishwasher Plastic burning smell

    Model Number: KDTE104DSS0
    Brand: KitchenAid
    Age: 1-5 years

    I walked downstairs two nights ago and the entire floor smelled like burning plastic. I quickly identified it was coming from the dishwasher. I checked that nothing had fallen onto the heater coil. Started to run it again, smelled plastic burning again and called a appliance repair company.

    The company's technician arrived and according to my wife some of the wires had caused plastic insulation to melt (pictures attached) . He stated that this was normal. Wires just happen to be melting. If they get destroyed they will fry the control panel. He was unable to explain why the wires were melting, stated that maybe over heating was causing the melting but that it wasn't a cause for concern. He said it was common and nothing to worry about unless it starts to emit smoke.

    This doesn't seem right to me, I don't think my house should smell of burning plastic when the dishwasher is running and it concerns me to have a dishwasher running that could start to smoke and possibly start a fire, especially as we often run it over night. I've attached some pictures as well.

    I would think that something is wrong and should get replaced...but not sure as this is beyond my area of expertise. Also, if there is something that could be fixed is it worth it. It's an expensive appliance but don't want to spend more to fix something that will just break again.

    Any help would be appreciated.

    The pictures are a bit too close. Which is OK but I can't tell where that location is . Is that inside the door panel?

    OK, Keep in mind I'm just looking at the pictures and pictures can sometimes be deceiving. The wires in your pictures don't look burned or melted. It looks like that's where the wires were touching the "black tarish" insulation. The inner door can get pretty hot during a wash cycle and heated dry cycle and the insulation can get a little soft and the brown spots on the wires is just the insulation.

    Current will produce heat and the more current, the more heat. Bad connections, loose connections, corrosion or worn out parts can cause an increase in current to a component. It can cause the wire insulation to melt and the heat can cause the wire strands to break down and burn in two. This usually always happens at the wire connectors on the components. It mostly happens to wires that carry a lot of current like the heating element or motor wires. The wires are sized larger to carry the current.

    The yellow wires in your pictures don't look like they carry much current (I don't know what they are connected to) and high current wouldn't cause a meltdown in the middle of the wire. What I see in the pics doesn't look like it would cause the "entire floor to smell like burning plastic".

    Most models will let you run the machine with the outer door off and there doesn't look like there's any bare spots on the wires so start a wash cycle and after the first drain cycle feel the wires with your hand to see if they are warm.
