The short answer
A dishwasher that will not drain is telling you the water has nowhere to go. On the DIT line the two ends of that path — the filter at the bottom of the tub and the connection at the sink — are both owner-accessible, and between them they explain most standing-water complaints. Listen for the pump before assuming it has failed. The name covers a broad group of numbers, so the ranking below holds across the group while the parts stay specific to the machine in front of you.
What you observe on these models
- Cycle stops early and the panel will not clear — Many machines abandon the cycle when the water has not gone, so a drain fault presents as a stalled cycle rather than as standing water.
- Water standing in the sump at the end of every cycle — An inch or so left over the filter, usually cloudy, with dishes that came out mostly clean.
- The machine hums but the water level does not move — The pump is being commanded and is drawing current, so the fault is mechanical rather than electrical.
- A gurgle at the sink each time the machine drains — The waste connection is restricted or the air gap is partly blocked, so the drain is fighting back.
- NEAR MISS — the tub is empty but dishes are wet — That is a drying complaint, not a drainage one, and it belongs on a different page.
Causes, most likely first on the DIT line
- Drain pump impeller jammed — The leading cause on this platform. It ranks high because the fix is usually removal of an object rather than a part, and the check is behind one screw-in filter.
- Blocked filter and sump screen — Close behind it. The filter is the one part of the drain path designed to catch things, so it is the first thing to fill; on a machine used daily it can choke in weeks rather than years.
- Kinked, looped or blocked drain hose — Third in order, and the one most often missed. A hose that has lost its high loop lets the waste siphon back, so the tub refills with dirty water while the pump is blameless.
Check in this order, and why
- Reach the impeller through the sump opening — With the power off, turn the impeller by hand. It should spin freely. A hard stop is an object, and the object is usually visible once the light is right.
- Take the filter out and look at the sump under it — Twist it free, rinse it, and put a hand into the well beneath — most of what blocks a drain is sitting there and comes out with a finger.
- Follow the drain hose from the machine to the waste — Look for a kink behind the cabinet, check it still rises to a high loop, and squeeze along its length for the hard spot that grease leaves.
Before you open anything
Safety
Switch the machine off at its breaker before a panel comes off or a hand goes into the sump — a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before disturbing a fitting, and never wedge the door interlock to watch a wash run.

When to call a technician
Owner-fixable: anything reached through the tub with the filter out. Service call: a pump that is silent when it should hum, a control that never calls for a drain, or a leak that appears once the drain is cured. Do not run repeated cycles to clear a blockage — it packs the debris tighter and can overheat a pump that is already stalled.
