The short answer
Standing water in a SHX tub is a blocked path far more often than a dead pump. With sixty-five codes in the table, this family spans several build generations and a wide range of ages in service — which is why wear causes rank higher here than they do on the brand-generic page.
What you observe on these models
- Clean water standing in the sump after every cycle — Clean water means the wash finished and the drain failed at the end.
- The machine hums at the end of the cycle but the water level does not move — The pump is being asked to run and cannot turn, or it turns against a blocked outlet.
- The cycle stops part way and the panel shows a fault — Most controls abort the cycle once the water is still there after a drain attempt.
- NEAR MISS — water under the machine rather than inside it — That is a leak, not a drain fault, and it has its own page for this family.
Causes, most likely first on the SHX family
- The filter and sump are packed with soil — First on this family, because the filter is the last thing between the food and the pump and the only part of the drain path an owner can reach without a tool.
- The drain hose is kinked, trapped or has lost its high loop — A hose crushed behind the machine when it was last pushed back, or one that has slipped out of its clip under the sink, produces exactly this symptom and leaves no trace inside the machine.
- The drain pump impeller is jammed by debris — Moved up on a family whose codes cover several generations: years of glass chips and fruit stones find the impeller eventually, and the hum-without-flow symptom is its signature.
- The disposal knockout plug was never removed, or the disposal is full — Kept high on the list because it outlives the installation: a plug left in place drains nothing from day one, and a disposal packed with waste blocks the same port later in life.
- The drain pump has failed electrically, or the control is not calling it — Last, because it is the only candidate that cannot be cleared by hand and the least common of the six.
Check in this order, and why
- Run the drain or cancel function first — It forces one clean drain attempt with nothing else happening, so you can hear whether the pump runs, hums or stays silent.
- Bail the tub out and pull the filter — Scoop the standing water with a cup and a towel, then twist the filter out and look in the sump with a light.
- Free the hose where it leaves the machine — The crush point is almost always where the hose passes the cabinet wall or sits behind the machine after it was last pushed back into place.
- Look at the pump inlet with the power off — With the breaker off and the sump dry, the pump inlet under the sump screen is where a bone chip or a piece of glass lodges.
- Stop here if the pump is silent — A drain step that produces no sound at all, with a clear filter and a clear hose, is an electrical fault at the pump or the control — and that is where the owner-side list ends.
Models in the SHX family — Some codes here are pinned to a single build and the rest are patterns covering several, so match the longest entry that fits the tag inside your door frame. The sixty-five codes fall into twenty leading groups, and that spread is the reason this page is written for the family rather than for one machine.

Before you open anything
Safety
Switch the breaker off before you reach into the sump or take the toe-kick off — a capacitor can hold a charge after the power is off, and you will be working with your hands in water. Assume there is broken glass in the sump, because there usually is: use a glove and a light, not bare fingers.
When to call a technician
The owner side of this fault ends at the pump inlet. Filter, sump, drain hose, air gap and disposal are all reachable with a towel and a torch, and they account for most of these calls.
