ASKO Dryer Error Code Heat protection

Heat protection means a thermostat in the rear section of the dryer has detected excessively high temperatures and shut the machine down. This is a safety response designed to prevent component damage. The most common reason is restricted airflow caused by a clogged lint filter or a dirty condenser unit. Cleaning these components is the recommended first step before attempting anything else.

No, you should not continue using the dryer while this error is active. The thermostat has detected a temperature level high enough to trigger a protective shutdown, and running the machine in this condition risks further overheating. Address the lint filter and condenser first, and confirm the error is resolved before resuming normal use.

If cleaning the lint filter and condenser resolves the issue, there is no parts cost involved. If the thermostat has failed and requires replacement, parts and labor costs typically range from around $100 to $250 depending on your location and the technician's rates. Addressing regular filter maintenance can help prevent this error from recurring and keep repair costs to a minimum.

Start by removing and thoroughly cleaning the lint filter, then clean the condenser unit if your model is equipped with one. Check that the exhaust duct is clear and free of kinks or blockages. Once everything is clean, restart the dryer to see if the error clears. If the error returns after cleaning, a technician should inspect the rear thermostat and its wiring.

A reset alone is unlikely to permanently clear the error because it does not address the underlying cause. If the lint filter or condenser remains clogged, the thermostat will trip again once the dryer heats up. Clean the filter and condenser before resetting, so the root cause is resolved and the error does not immediately return.
