KitchenAid Dryer Error Code E6

E6 means the dryer's exhaust temperature exceeded 190°F (87.7°C) during operation. When this threshold is reached, the control board shuts off all outputs immediately as a safety measure. The code points to a problem with airflow restriction, the heating system, or the exhaust temperature sensor. The dryer will not run again until the root cause is identified and resolved.

No, you should not attempt to bypass or ignore E6. The code indicates the exhaust system reached a temperature that poses a genuine fire risk. The dryer shuts all outputs off automatically for this reason. Continue using the dryer only after the cause of the overheating has been fully diagnosed and corrected.

Repair costs depend on the cause. Duct cleaning and lint removal can cost nothing or up to $100 to $150 if a professional duct cleaning service is used. Replacing a cycling thermostat typically runs $40 to $120 in parts and labor. A heating element replacement generally falls in the $100 to $250 range depending on labor rates in your area. Sensor replacements are usually on the lower end of component costs.

Some causes of E6 are DIY-friendly, particularly cleaning the lint screen, clearing the lint trap housing, and inspecting the exhaust duct for blockages or kinks. If those steps do not resolve the fault, further diagnosis requires testing the exhaust temperature sensor and thermostat using the procedure outlined in TEST #3b. Heating element and thermostat replacements are manageable for experienced DIYers but do require disassembling the dryer cabinet.

A power cycle may clear the displayed code temporarily, but if the underlying cause of the overheating is still present, E6 will return once the dryer reaches operating temperature again. Resetting without addressing the root cause does not make the dryer safe to use and risks repeated thermal shutdowns or a fire hazard.
