Washer-dryer combo shows E61 and will not heat during the dry cycle; clothes remain wet or take excessively long to dry.

Safety first: Unplug the appliance. Heating components can retain heat; allow time to cool before touching.

• Confirm airflow: Before electrical checks, ensure the combo's exhaust duct (if vented) is not crushed or blocked. Poor airflow can overheat and open safety thermostats.
• Access heater assembly: Remove the rear panel or top/rear cover (model-dependent) to locate the dryer heating element housing and thermostats.
• Inspect wiring: Look for burnt or loose connectors on the heater terminals and thermostats. Repair or replace any damaged connectors.
• Test thermostats and thermal cutoff: Using a multimeter, check the high-limit thermostat and thermal cutoff for continuity. Replace any that test open.
• Test heating element: Disconnect power leads from the element and measure resistance across the terminals. An open circuit indicates a failed element that must be replaced.
• Replace failed components: Install a new dryer heating element or high-limit thermostat/thermal cutoff kit as needed. Reassemble, ensure proper ducting, and run a test dry cycle while monitoring for normal heat.
