Is it an emergency?
Is a burning smell from a Thermador 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 from your Thermador dishwasher, often described as electrical, rubber, or plastic, indicates a serious internal issue. This odor typically points to an overheating electrical component such as the wash motor, heating element, or a shorted wire. Root causes can include a failing motor drawing too much current, a faulty heating element, or foreign objects melting on hot surfaces.
Tools & parts
A reliable multimeter is crucial for testing continuity and resistance of electrical components like the heating element or motor. A basic set of screwdrivers (Phillips, Torx) will be needed to access the dishwasher's internal panels and components. You might need replacement parts such as a new Thermador heating element or a wash motor if tests confirm their failure.
Safety first
Immediately shut off power to the Thermador dishwasher at your home's main electrical breaker to prevent further damage or fire. Also, turn off the water supply valve to the dishwasher to avoid any potential leaks or water damage during inspection. Always exercise extreme caution when dealing with electrical appliances, as live wires can cause severe shock or burns even after the initial power cut if not properly verified.
When to call a pro
You should call a professional technician if the burning smell persists after basic troubleshooting or if you identify complex electrical issues beyond your comfort level. Specific failure modes like a burnt-out main control board or a seized wash motor requiring specialized tools and expertise warrant professional intervention. Attempting repairs on high-voltage components without proper knowledge can lead to further damage, personal injury, or even a fire hazard.
Questions people ask
Why does my Thermador dishwasher smell like burning plastic?
This often indicates an issue with the heating element or a plastic component touching it. Check for melted plastic items that may have fallen onto the element or a failing heating element itself. Ensure no plastic dishware has come into direct contact with the element during the drying cycle.
Can a burning smell from my Thermador dishwasher be dangerous?
Yes, a burning smell is a serious warning sign and can indicate an electrical short, overheating component, or even a potential fire hazard. Immediately disconnect power to the appliance at the circuit breaker to prevent any further risks. Do not operate the dishwasher until the source of the smell is identified and resolved.
What Thermador components commonly cause a burning smell?
Common culprits include the wash motor, heating element, or wiring harnesses that have shorted or overheated due to a fault. Debris caught in the motor or pump assembly can also cause friction and excessive heat, leading to a burning odor. Inspect these areas thoroughly after ensuring the power is off.
