ASKO Washer Error Code F5

The F5 code on an Asko washer means the machine has detected excessive foam inside the drum after the main wash phase. This function is built into select Asko models and is designed to flag over-sudsing before it can interfere with rinsing or machine operation. The most common cause is using too much detergent or a detergent that is not formulated for automatic low-lather washing. Running a rinse cycle and correcting the detergent dose or type usually resolves the issue.

You should not continue a full wash cycle while F5 is active, as excess foam can reduce rinse effectiveness and potentially interfere with pump and sensor operation. Running a rinse-only cycle first to clear the suds is the recommended step before proceeding. Once the foam has been cleared and the detergent issue addressed, the machine is safe to use normally.

In most cases, fixing an F5 error costs nothing beyond purchasing the correct low-lather detergent, which typically ranges from $10 to $25 per container. If the issue turns out to be a faulty foam sensor or a control board problem, repair costs can range from $100 to $400 or more depending on the specific component and labor involved. Because the code is most often detergent-related, it is worth exhausting the free diagnostic steps first before pursuing component repair.

Start by running the rinse program once to clear the excess suds from the drum. After the rinse completes, check that you are using a low-lather or HE-rated detergent and that you are using the correct dosage for your load size. If the code returns after making these adjustments, inspect the dispenser drawer and drum for detergent residue buildup and clean them thoroughly.

A reset alone is unlikely to permanently clear the F5 code if the underlying cause, excess sudsing from detergent type or dosage, has not been addressed. The foam detection check occurs after the main wash, so the code will likely return on the next cycle under the same conditions. Running a rinse cycle and correcting the detergent are the recommended steps before attempting any reset.
