In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
Smoke or flames: get everyone out and call 911.
No gas smell, smoke or flames? Turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.

Symptoms & causes
A burning smell from your Whirlpool water heater often indicates an electrical issue or overheating of internal components. This could be due to a faulty heating element, loose wiring connections, or a failing thermostat causing the element to run continuously. Dust accumulation on electrical components or a motor (if it's a heat pump model) can also burn off, producing a similar odor.
Tools & parts
You will need a multimeter to test for continuity and voltage on electrical components like heating elements and thermostats. A screwdriver set is essential for accessing panels and tightening terminals, along with a wire brush for cleaning connections. Replacement parts like a new Whirlpool heating element or a thermostat might be necessary if components are found to be faulty.
Safety first
Always shut off the power to the water heater at the circuit breaker before performing any inspection or repair to prevent severe electrical shock. Turn off the cold water supply valve to the unit to prevent water flow and potential leaks during component replacement or draining. Be aware of hot water and steam, and wear appropriate personal protective equipment like insulated gloves and safety glasses to avoid burns.
When to call a pro
If the burning smell persists after basic troubleshooting and component checks, or if you observe charred wiring or melted insulation, it's time to call a professional technician. A technician should also be consulted if the pressure relief valve is actively discharging hot water or steam, indicating dangerously high internal pressure within the tank. Any signs of a leaking tank or a gas leak (for gas models) absolutely require immediate professional intervention due to severe safety risks.
Questions people ask
Why does my Whirlpool electric water heater smell like burning plastic?
A burning plastic smell often points to overheating electrical insulation or a melting wire within the unit. This can be caused by loose connections creating excessive resistance or a faulty heating element drawing too much current.
Can dust cause a burning smell from my water heater?
Yes, dust and debris accumulating on heating elements or electrical contacts can burn off when the unit operates, producing a burning odor. Regular cleaning of the accessible exterior and vents can help prevent this issue.
Is a burning smell from my Whirlpool water heater always serious?
While sometimes it's just dust burning off, a persistent or strong burning smell is always serious and indicates an electrical fault or overheating. It should be investigated immediately to prevent potential fire hazards or further damage to the appliance.
