Dryer shows E18 and may stop with a beeping alarm; often related to overcurrent or short circuit detection.

Safety first: Unplug the dryer and do not reset the breaker repeatedly without finding the cause. Risk of fire or electric shock.

• Visual inspection: Remove rear and side panels to inspect wiring for burn marks, melted insulation, or loose connections.
• Test heater to ground: Disconnect the heating element and measure resistance between each terminal and the metal chassis. Any continuity indicates a shorted element that must be replaced.
• Check motor windings: Disconnect the motor and measure winding resistance. Very low resistance or continuity to ground suggests a shorted motor.
• Inspect harness: Follow the main harness from the power entry to the heater and motor. Repair or replace any damaged sections.
• PCB power section: If all loads test good, the power supply on the main PCB may be faulty. Board replacement is recommended and should be done by a professional.
