How to Fix / Troubleshooting
Safety first: Unplug the appliance and allow it to cool fully before working on dryer components.
F13 applies to Hotpoint washer-dryers and relates to the drying system.
- Access dryer components: Remove the top cover. The dryer heater and NTC are usually located in the upper rear ducting.
- Check airflow: Inspect the dryer air duct and fan for lint build-up. Clean thoroughly to restore airflow.
- Test dryer NTC: Disconnect the NTC sensor and measure resistance at room temperature (typically 20–30 kΩ). Replace if open circuit or reading is far out of specification.
- Test dryer heater: Measure resistance across the heater terminals (usually 20–40 Ω). If open circuit, replace the heater assembly.
- Inspect wiring: Ensure all connectors are tight and wires are not burnt.
- Reassemble and test: Run a short drying cycle to confirm heat and that F13 does not reappear.
