6 Reasons Why Your Dishwasher Has A Burning Smell
If you have just bought a new dishwasher and you smell burnt odor in dishwasher, then there is nothing to worry about. The new dishwasher usually comes wrapped in a plastic sheet to prevent any damage during shipping. So if you do not remove the plastic sheets it can lead to the melting of plastic when it is switched on.
In this case, you can eliminate burning smell in dishwasher by removing the melted plastic residues around the heating element. After that, you will experience that the burning odor in dishwasher will eventually fade away after continuous usage.
Heating Element and Melted Plastic
If your dishwasher is not new you may wonder why your dishwasher has a burning smell. Then you must check if the heating element is in direct contact with a plastic utensil. Most of the time during the drying cycle, the heating elements come in contact with plastic utensils and the plastic eventually starts melting down.
The best way of fixing smelly dishwasher is to switch off the dishwasher and let the heating element cool down. After that remove the plastic residue that is causing the burning odor. This is one of the most common causes why your dishwasher has a burning smell.
However, if there is no plastic piece near the heating element then the burning smell indicates the failure of the heating element. This is your indication to call a technician so that he can fix your heating element or replace it with a new one.
Faulty Power Cord
When the burning smell is not coming due to the heating element then 80% of the time it is due to wiring issues or loose connections. When your dishwasher power cord is plugged loosely into the wall socket it gives off sparks. This spark can cause the burning of the heat insulation, which is why you smell burnt odor in dishwasher.
It’s not actually the dishwasher that is faulty but the power cord is the reason why your dishwasher has a burning smell. For troubleshooting burning smell, remove the plug and smell it. If there is any melted insulation then replace the power cord with a new one. However, if you don’t have the skills to do it by yourself, make sure to call a technician for support.

Nonetheless, the location of each component differs depending on the model of the dishwasher. So you should read the user’s manual before doing the inspection.
