What the Maximum program time error code actually means

Your Asko dryer ran for 3 hours straight without finishing the drying cycle, so it shut itself off as a precaution. This usually means something is preventing clothes from drying efficiently, such as a clogged lint filter, a blocked vent, or wet laundry that had too much water left in it from the washing machine. Check the filter and venting first before restarting.

Questions people ask about Maximum program time

What does Maximum program time mean on a Asko dryer?
It means the dryer ran for its maximum allowed duration of 3 hours without completing the drying cycle and then shut itself off automatically. This is a protective feature rather than a single specific fault. The cause can range from a clogged lint filter or blocked exhaust duct to a faulty humidity sensor or an incorrect electrical supply. Investigating airflow and filter condition is the recommended starting point.
Will resetting the dryer clear the Maximum program time error?
Resetting or powering the dryer off and back on will clear the displayed error and allow you to start a new cycle. However, if the underlying cause is not addressed, the dryer will simply run for another 3 hours and stop again with the same result. A reset is only useful after the root cause, such as a blocked filter, restricted duct, or faulty sensor, has been corrected.
How much does it cost to repair a Maximum program time error on an Asko dryer?
Repair costs vary depending on the cause. If the issue is simply a clogged filter or blocked duct, there may be no parts cost at all, though a professional cleaning service could run between $75 and $150. If the humidity sensor or its associated wiring needs replacement, parts and labor combined typically fall in the range of $100 to $300 depending on parts availability and local labor rates. Electrical supply corrections may involve additional electrician fees.
How do I fix the Maximum program time error on my Asko dryer?
Start by cleaning the lint filter, condenser, and fan housing thoroughly, then inspect the external vent duct for any obstructions or kinks. Confirm the dryer is connected to a correctly rated single-phase 10A circuit. If airflow and electrical supply are both confirmed good, check the humidity sensor and its wiring for damage or corroded connections, and replace any faulty components before running the machine again.
Is it safe to keep using the dryer after this error appears?
The dryer has already stopped itself as a precaution, so there is no immediate danger from the shutdown. Running the machine again without resolving the cause is not recommended, as repeated extended cycles place additional stress on heating elements, motors, and wiring. Identify and fix the underlying issue before resuming normal use.
