ASKO Washer Error Code Water outlet

The Water outlet error on Asko W640 and W660 washers means the machine detected that draining took longer than it should have. The washer monitors drain time and triggers this fault when water is not removed within the expected window. It is most commonly caused by a blockage in the drain hose or a clogged pump filter. The machine will stop the cycle until the issue is resolved.

You should not continue running the washer while this error is active. The machine halts the cycle as a protective measure, and attempting to bypass or ignore it could result in water remaining in the drum or, in a worst case, overflow. Resolve the drainage issue before resuming normal use.

If the issue is a blocked hose or dirty filter, the repair is typically free since it only requires cleaning and no replacement parts. If the drain pump has failed and needs replacement, parts and labor combined can range from roughly $150 to $350 depending on your location and the service provider. Cleaning the filter and inspecting the hose yourself first is always the recommended starting point before calling a technician.

Start by checking the drain hose outlet for any foreign objects or buildup and clear the hose if anything is blocking it. Next, locate and clean the pump filter, which collects lint and debris from laundry. Also inspect the hose for kinks or sharp bends that could restrict flow. If the hose and filter are both clear and the error returns, the drain pump itself may need to be tested and potentially replaced.

A reset may temporarily clear the fault display, but if the underlying cause, such as a blocked hose or clogged filter, has not been addressed, the error will return during the next drain cycle. Always identify and fix the root cause before attempting a reset so the machine can complete a full cycle without faulting again.
