Dryer does not heat, F05 displayed, drum turns normally but clothes stay cold

Safety first: Disconnect mains power before accessing the rear panel or heater assembly.

Steps to check:

• Confirm no heat: Run the dryer on a high heat program for 5–10 minutes. Carefully feel the air at the exhaust or inside the drum (do not touch metal parts). If still cold, proceed.
• Access heater: Remove the rear panel to expose the heater housing. Visually inspect the heater terminals and wiring for burning or discolouration.
• Test heater resistance: Disconnect the heater connectors and measure resistance across the heater terminals. A typical reading is 20–60 Ω. An open circuit indicates a failed element.
• Check wiring and connectors: Look for loose spade terminals, melted connectors, or broken wires. Repair or replace as needed.
• Inspect control board relay: If the heater tests good, the issue may be a faulty heater relay on the PCB. Look for burnt relay contacts or tracks; board replacement is usually required.
