Is a burning smell from a Sub-Zero dishwasher an emergency?
Treat it as urgent. Turn it off and unplug it or switch off its breaker, and do not use it again until the cause is found. If you see smoke or flames, or smell gas, get everyone out and call 911.
Symptoms & causes
A burning smell emanating from your Sub-Zero dishwasher often indicates a serious underlying issue, ranging from melting plastic items to electrical component failure. This acrid odor might be accompanied by smoke, unusual noises like grinding or buzzing, or a complete lack of power to the appliance. Root causes typically include an overheating wash motor, a shorted heating element, or damaged electrical wiring insulation.
Tools & parts
A reliable multimeter, such as a Fluke 117, is essential for checking electrical issues like continuity and resistance in components. A comprehensive screwdriver set (e.g., Klein Tools 11-in-1) will be needed to access various panels and components. You might also need specific replacement parts like a new Sub-Zero wash motor, a heating element, or a wiring harness if a component is found to be faulty.
Safety first
Immediately shut off the power to the dishwasher at your home's main electrical circuit breaker to prevent further damage or fire. If accessible, unplug the appliance from its wall outlet as an additional safety measure. Always be cautious of potential electrical shock hazards, burns from hot components, and the risk of fire when investigating a burning smell.
When to call a pro
You should call a professional technician if the burning smell persists after you've performed basic checks and eliminated obvious causes like melted plastic. A professional is also necessary if you observe visible smoke, sparks, or if complex electrical tests involving the main control board or motor windings are required. Any situation where you are uncomfortable working with high voltage or cannot confidently identify the source of the burning smell warrants expert intervention.
Questions people ask
What causes a burning smell in a Sub-Zero dishwasher?
Common causes include a failing wash motor, a shorted heating element, or melted plastic from a foreign object that has fallen onto the element. Electrical wiring insulation can also burn if there's an overload or short circuit within the appliance.
Is it safe to continue using my Sub-Zero dishwasher if it smells like burning?
No, it is extremely unsafe to continue using your dishwasher if it smells like burning. Immediately discontinue use, unplug the appliance, and turn off the circuit breaker to prevent potential fire or further damage to your home and appliance.
How can I identify if it's an electrical burning smell versus plastic?
Electrical burning often has a sharp, acrid odor similar to ozone or burnt rubber, while melting plastic usually smells sweeter and more distinctively like burnt plastic. Inspect for visible charring or melted components, which can help pinpoint the source.
