ASKO Dryer Error Code H5

H5 is an overheat fault specific to Asko electric dryers. It is triggered when the temperature sensor detects a temperature of 85 degrees Celsius or higher in the heating system. The dryer shuts down the heater automatically as a safety response. The cause can be restricted airflow, a faulty sensor, or a problem with the heating circuit components.

No, you should not continue operating the dryer while the H5 fault is active. The error indicates the heating system reached a temperature at or above 85 degrees Celsius, which is a potential fire risk if the underlying cause is not addressed. Disconnect the dryer from power and resolve the issue before running another cycle.

Repair costs vary depending on the cause. If the fix is simply cleaning a blocked duct or lint trap, there may be little to no parts cost, though a service call to diagnose the issue typically runs between 80 and 150 dollars. Replacing a temperature sensor, thermostat, or thermal limiter generally adds 20 to 80 dollars in parts. A full heating element replacement can bring total repair costs into the 150 to 350 dollar range including labor.

In many cases, yes. Start by thoroughly cleaning the lint filter, inspecting the exhaust duct for blockages or kinks, and checking that the exterior vent flap opens freely during operation. If clearing airflow restrictions does not resolve the fault, diagnosing the temperature sensor, thermostat, or heating element will require a multimeter and some technical comfort level, so a technician may be advisable for those steps.

A power reset may temporarily clear the displayed fault, but the H5 code will return if the underlying cause is not corrected. If restricted airflow is the problem, clearing the blockage before resetting is necessary. Resetting without addressing the root cause risks repeated overheating and possible damage to internal components.
