A foreign object, such as a plastic utensil or food wrapper, may have fallen onto the heating element
If your dishwasher smells like burning plastic, it is crucial to address the issue promptly to prevent potential damage or safety risks. One possible reason for this smell is a foreign object, such as a plastic utensil or food wrapper, falling onto the heating element. Here are some steps you can take to address this issue:
Firstly, it is important to stop the dishwasher cycle and unplug the appliance to ensure safety. Once the dishwasher is cooled down, remove the bottom rack and thoroughly inspect the area near the heating element. Check for any foreign objects, such as plastic utensils, food wrappers, or other debris, that may have fallen onto the heating element. Remove any foreign objects you find.
It is crucial to handle this situation with care as the heating element can become extremely hot during the wash cycle. Make sure to wear protective gear, such as gloves, to avoid any burns or injuries. If plastic has melted onto the heating element, carefully remove as much of it as possible without using anything metallic to scrape it off. Plastic utensils or food wrappers can often fall between the cracks in the dishwashing racks and burn on the heating coil, causing the burning plastic smell.
In some cases, the smell of burning plastic may persist even after removing the foreign object. This could be due to plastic residue remaining on the heating coil or other components. To reduce the odor, you can spread vinegar on the floor of the dishwasher before turning it on. White vinegar is particularly effective in neutralizing dishwasher odors. Place two cups of vinegar in a dishwasher-safe bowl and put it on the bottom rack of your empty dishwasher, then run a cycle.
If the burning plastic smell continues, it is recommended to contact a qualified technician to inspect and repair the dishwasher. They will be able to diagnose the issue accurately and suggest appropriate solutions. It is important not to ignore the burning smell as it could indicate a more serious problem, such as an electrical malfunction or fire hazard.
