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.

Is it an emergency?
Is a burning smell from a Haier water heater an emergency?
Treat it as urgent. Turn it off and 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 Haier water heater typically indicates an electrical issue or organic material burning on a hot surface. Common symptoms include a distinct acrid odor, sometimes accompanied by a tripping circuit breaker or visible smoke from the unit. The root causes often involve overheating electrical components like wiring insulation, a faulty thermostat, or dust and debris accumulating on the heating elements and igniting.
Tools & parts
You will need a multimeter to test electrical components. A basic screwdriver set is essential for accessing internal panels. A wire brush or compressed air can be useful for cleaning dust and debris from heating elements.
Safety first
Immediately shut off the power to your Haier water heater at the main electrical panel's circuit breaker to prevent electrical shock and fire hazards. Close the cold water inlet valve to the water heater to prevent water flow and potential scalding if components are removed. Never attempt to track down or repair a burning smell without first confirming both electrical power and water supply are completely shut off to the unit.
When to call a pro
A persistent burning smell after cleaning, or if the circuit breaker repeatedly trips, indicates a severe electrical fault requiring professional attention. Specific failure modes like a shorted heating element causing excessive current draw or a complete failure of the main control board necessitate expert testing and replacement. If you detect melted wiring insulation, a burning smell from the main control panel, or are uncomfortable working with high voltage, contact a certified Haier appliance technician.
Questions people ask
Why does my Haier electric water heater smell like burning plastic?
This often indicates overheating electrical components such as wiring insulation, the thermostat, or the heating element terminals. It could also be dust or debris burning on a hot surface, but plastic smell usually points to electrical issues.
Can I continue to use my Haier water heater if it smells like burning?
Absolutely not; a burning smell is a serious warning sign of potential electrical fire or component failure. Immediately shut off power to the unit at the breaker and do not restore it until the issue is identified and repaired.
What's the difference between a burning dust smell and a burning electrical smell?
Burning dust often smells like something is scorching, similar to a dusty heater turning on for the first time, and usually dissipates quickly. A burning electrical smell is sharper, more acrid, and often persistent, indicating melting plastic or insulation.
