Dryer shows E14 and may shut down unexpectedly; sometimes associated with tripping the household breaker.

Safety first: Unplug the dryer immediately. Do not continue to use the appliance until the fault is identified and corrected, as there is a risk of electric shock.

• Inspect mains cable and plug: Check for cuts, crushed sections, or burn marks. Replace the mains cable if any damage is found.
• Check heater insulation: Remove the rear panel to access the heater. Look for signs of arcing, burn marks, or contact between the heater coil and the metal casing. Replace the heater assembly if damaged.
• Inspect suppression filter: Locate the mains interference filter (often near the entry point of the mains cable). Look for bulging, cracking, or burning. Replace if any damage is visible.
• Check for moisture: Ensure there are no water leaks inside the cabinet, particularly around the heater, pump, or condenser areas. Dry any moisture and correct the source of leaks.
• Insulation testing (advanced): A qualified technician can perform an insulation resistance test between live parts and earth to pinpoint leakage. If you are not equipped for this, seek professional service.
