ASKO Dryer Error Code H2

The H2 code on an Asko dryer signals a fault in the drying temperature sensor circuit. The control board has detected either an open circuit, meaning the signal is absent, or a short circuit, meaning the signal is out of the expected range. The dryer stops operation when this error appears to prevent unreliable or unsafe drying conditions. Resolving it requires checking the sensor connection and replacing the sensor if it is defective.

Switching the dryer off and back on will clear the H2 error display temporarily. However, if the underlying sensor fault or wiring issue has not been corrected, the code will return as soon as the dryer attempts to run a cycle again. A reset alone is not a fix, only a way to confirm whether the fault is intermittent or persistent.

If only a loose connector is involved, there may be no parts cost at all. Replacing a faulty drying temperature sensor typically costs between $20 and $80 for the part, depending on the specific model. Adding professional labor, total repair costs generally range from $100 to $250. A control board replacement, if needed, would be at the higher end of the cost spectrum.

A knowledgeable DIYer can start by checking whether the sensor connector is fully seated and whether any wires are visibly damaged. If reconnecting a loose harness clears the problem, no parts are needed. If the sensor itself has failed, replacing it requires disassembling part of the dryer, which is manageable for someone comfortable with appliance repair but may be better handled by a technician if you are unsure.

It is not recommended to continue using the dryer while H2 is active. The temperature sensor is what allows the control board to regulate heat during the drying cycle. Without reliable sensor data, the dryer cannot properly control temperatures, which creates a risk of overheating or incomplete drying. Address the fault before resuming use.
