On this make the machine will tell you so in one of three unrelated ways depending on which generation" url: "https://askomiami.support/symptoms/dishwasher-not-draining/" date_modified: "2026-09-13" Appliance type: "Dishwashers" --- # Asko dishwasher not draining ### What to do in the next ten minutes Switch the machine off at the wall. Take out the bottom basket and lift the filter stack out — coarse filter, fine filter, and the plate beneath — and rinse all of it under a tap. Look in the sump for glass, a cherry stone or a label. Put the stack back and turn it until it seats; a quarter-turn short is the reason for the next call. Then run a rinse program and watch whether the water goes. ### Why we ask which machine before we answer On most makes a drainage code is a drainage code. Here there are three dishwasher generations in South Florida kitchens and they number their messages independently — the legacy boards blink theirs through the program lights, the current machines print F-numbers on a display, and the Outdoor door uses a colon format whose numbers collide with the current list. Telling us the model from the door edge is worth more than the number on its own. ### What the panel costs you Almost every Asko dishwasher here is integrated behind a custom door. That means the panel and the toe kick come off before the machine can move, and it is the reason a visit is quoted from the getting-in rather than from the part. It is also the reason the free checks deserve doing properly: two minutes at the front of the machine covers the filter, and everything beyond it opens with a joinery job. The filter stack has loaded up Weeks of plate scrapings settle into the fine filter until the pump cannot draw through it. Leading cause on every generation, and the only one you can put right for free. Something is jammed in the pump Glass, a stone or a screw reaches the impeller and stops it. The machine will often raise a pump-specific message rather than a drainage one, which is a useful distinction if the display prints words. The problem is at the sink, not the machine An air gap silted up, a disposal branch never punched out, or a hose crushed when the machine was last pushed back. All three drain slowly for months before they stop. Does the sink drain normally? Run the tap and watch. A slow sink and a full dishwasher are one problem, and it is not the appliance. Is the filter seated? Lift it, rinse it, and turn it until it locks. People rinse the top filter and leave the plate beneath, which is where the load actually is. What does the machine say, exactly? The characters matter: F11 on a display machine and F:45 on an Outdoor door are different tables. Write down the model from the door edge with it. Water standing in the bottom when the program ends What it usually means The filter stack lifts out by hand, costs nothing, and usually ends this Three code schemes describe this behavior; the model decides which one you are reading If the sink drains slowly too, the appliance is innocent What to do in the next ten minutes Switch the machine off at the wall.

Yes, and it helps. Sponge the standing water out before anybody arrives — it makes the filter reachable and stops the smell that follows a day of standing water. ### It drained once and then stopped again. Partial blockage, not a dead pump — a short program moves little enough to get away with it. Mention that when you call; it decides what goes on the van. --- **[Read full article: Dishwasher not draining](https://askomiami.support/symptoms/dishwasher-not-draining/)**
