All the lights stay on after a cycle completion even after I siphoned all the remaining water in the filter sump.(After opening and closing the door. ASKO model 1585)

Hello, the reason for the light flash error is the unit either didn't drain properly, overfilled somehow or has a leak which is filling the "overfill basin" ( it's designed to, that way it doesn't get to your floor...in theory ). Check your drain hose by removing it where it connect's to your home plumbing via under sink pipe or food diposer/garberator. You'll also need to remove the lower access panel, or kick plate as it is sometimes referred to, and absorb the water in the basin before it will run a cycle...or wait a few days for enough water to evaporate from the basin ( shut off the power/breaker before doing so ) then look for evidence of a leak. Check at the fill valve, (to the left) the drain pump, (slightly to the left-center) as well as the circulation pump & hoses, ( it is much more difficult to see...directly behind the big gray main sump assembly). That should get you moving forward. The Asko can be a challenge to work on if you've never worked on one. That is why I usually suggest calling a pro, preferably an authorized Asko servicer. It may save many unessasary part's being changed as I see too often with these. Hope that help's, good luck. macmarkus :)
