Part: Control panel / software mode

Heating element failure or bad thermostat/temperature sensor

How to Identify: Steamer powers on but does not heat; continuity test with multimeter shows open circuit in element or sensor.

Part: Heating element, thermostat, temperature sensor

Mineral buildup or scale reducing heat transfer

How to Identify: Cloudy white scale on heating surfaces; long-term hard water use; reduced steam output without complete failure.

Part: Heating chamber around element

Insufficient water in steamer basin

How to Identify: Water level below minimum required line; unit will not heat or may beep without heating.

Part: Water reservoir / basin
