KitchenAid Dishwasher: smoking from hole in door
What is this symptom?
If your KitchenAid dishwasher is smoking from a hole in the door, it's crucial to address this issue immediately. This alarming symptom typically occurs during the drying cycle, releasing smoke and an acrid odor. Common causes include melted plastic on the heating element or accumulated residue burning. Ignoring this could lead to more severe damage or safety hazards.
Important Tips for KitchenAid Models
- Community reports note possible control board connector melting/smoking in older KitchenAid models; visible blackening around connectors.
Possible Causes
Non‑dishwasher‑safe plastic or foreign object melted on heating element
How to Identify: Burning plastic odor, melted plastic residue visible near the bottom heating element after opening door; smoke appears during drying when element is active.
Part: Heating element / melted plastic debris
Accumulated food residue or debris burning on heating element
How to Identify: Smoke without obvious melted plastic; may coincide with long neglected interior cleaning; dark residue near element.
Part: Heating element / interior surfaces
Electrical component overheating / short circuit (rare KitchenAid specific potentially control area)
How to Identify: Smoke appears with acrid burning smell from upper control area rather than bottom; possible scorching or melting on PCB/connectors.
Part: Control board or wiring
DIY Solutions
Remove melted plastic and debris from heating area
- Ensure dishwasher is turned off and power is disconnected (breaker off).
- Let interior cool completely before opening the door.
- Inspect bottom interior around heating element for melted plastic or debris.
- Using a plastic scraper/wooden spatula, gently remove plastic or residues from around the element.
- Vacuum or wipe away loose debris, then run a short empty cleaning cycle to clear any remaining particles.
Check and clean interior debris and rack positioning
- Open dishwasher after it is cooled and disconnect power.
- Remove racks if needed to examine for stuck items near heating coil.
- Clean interior and ensure no plastic items are misplaced on bottom rack.
- Load items so plastics are on upper racks away from heat source.
