Washer-dryer stops during drying cycle with E09; clothes remain wet and cold.

Safety first: Unplug the appliance and allow it to cool fully before working on the dryer section.

• Check basic airflow: Ensure the lint filter (if accessible) is clean. On many Bush washer-dryers, lint accumulates in internal ducts rather than a removable filter.
• Inspect rear ducting: Remove the rear panel and locate the dryer heater housing and ducts. Check for heavy lint build-up restricting airflow and carefully vacuum or brush it out.
• Check thermostats: On the heater housing, locate the thermal cut-outs/thermostats. Ensure their connectors are secure. Some TCOs are resettable with a small button; if present, press gently to reset.
• Heater continuity (if you have a meter): Test the dryer heater element for continuity. An open circuit indicates a failed heater that must be replaced.
• Replace components: If the heater or TCO is faulty, replace with Bush-compatible dryer heater and thermostats. If all components test good but E09 persists, the control PCB or dryer relay may be defective and require professional service.
