Unit trips the household circuit breaker or GFCI when starting or during heating.

Safety first: Do not repeatedly reset a breaker that trips; this indicates a potentially dangerous fault.

• Try another outlet: Plug into a different properly rated outlet to rule out a weak breaker (do not use extension cords).
• Inspect cord: Check for cuts or crushed areas. Replace if damaged.
• Check for moisture: If the unit was recently washed or exposed to steam, let it dry unplugged for 24–48 hours.
• Internal inspection (advanced): With the unit unplugged, inspect heater and wiring for signs of arcing or contact with the metal chassis. Replace any shorted components or wiring.
• PCB replacement: If no external shorts are found, the main control PCB may have a shorted component and should be replaced.
