Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The sink or the disposal
The dishwasher drains into it. A slow sink is a dishwasher that will not drain, and it is not an appliance problem.

The disposal plug never removed
On a new installation, the knockout in the disposal inlet. It costs nothing and it is a real finding.
Appliance installation from $225 -
The high loop
The drain hose is supposed to rise before it falls. Without it, waste comes back and the machine never empties properly.

Filters and a machine that is not level
Both are on the maker's own checklist for this condition and both are free to correct.

The drain pump
Jammed with glass or a stone-fruit pit far more often than failed. Running it repeatedly is how a jam becomes a replacement.

Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
Run the disposal and the tap
A sink that drains slowly explains everything and is outside the appliance.
-
02
Look at the drain hose behind the machine
Kinks and a missing high loop are both visible.
-
03
Clean the filters
They are designed to be removed by hand and they are frequently the whole answer.
-
04
Check it is level
Front to back and side to side. It affects what the machine measures as well as how it drains.
How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

About Viking dishwasher not draining
The fastest diagnosis is the code
Run the garbage disposal and check the sink drains freely. If the dishwasher was installed recently, check the plug was knocked out of the disposal inlet — it is a genuinely common oversight and it produces exactly this.
Six checks, and most of them are free
The manufacturer's own action list for this condition is the sink, the disposal, the disposal plug, the hose, the level and the filters. Not one of those is inside the machine. That is why this page is written the way it is: the technician's first six steps are steps you can take yourself.
Where it does become the appliance
When the drain path is proved clear and the machine still will not empty. Then it is the drain pump or its control, and that is a real repair — with the machine coming out from under the counter.

Before you book
Questions about viking dishwasher not draining
It was fine until the plumber came.
Then check the disposal knockout and the high loop, in that order. Both are steps in the dishwasher installation that a plumbing visit can undo without anybody noticing.
It is making a grinding noise as well.
Stop running it. That is almost always something hard in the drain pump, and every additional cycle is wear on a part that was fine an hour ago.
How much water is normal at the bottom?
A small amount in the sump is normal and by design. Standing water above the filter at the end of a cycle is not.
