Dryer displays E17; often linked to overcurrent or short circuit detection in the motor or heater circuit.

Safety first: Unplug the dryer. Do not attempt to reset or bypass safety devices without finding the cause of the short.

• Visual inspection: Look for burnt smells, scorch marks, or melted insulation around the heater, motor, and wiring.
• Test heater to earth: With the heater disconnected, measure resistance between each heater terminal and the metal chassis. Any low resistance indicates a shorted element that must be replaced.
• Check motor windings: Measure resistance between motor terminals and between each terminal and earth. Replace the motor if a winding is shorted to chassis.
• Inspect harness routing: Ensure no wires are pinched or rubbed through where they pass through holes or along metal edges.
• PCB check: If all loads and wiring are sound, the fault may be in the PCB's power devices. Replace the board if necessary.
