The short answer
When a SHX dishwasher stops cleaning properly, the water is almost always the problem — either it is not reaching the soil or it is not carrying detergent when it arrives. 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
- Grit on the lower rack while the upper rack is clean — The two racks are fed by different spray arms. A clean top and a dirty bottom points at the lower arm — blocked jets, or an arm that a pan handle stopped from turning.
- Everything comes out wet, plastics worst of all — Plastic holds the least heat, so it dries last on any dishwasher that dries by condensation rather than with an exposed element.
- Cloudy interior and a sour smell with the poor washing — Soil that never left the tub. It is the same root cause as the grit, seen from the nose instead of the eye.
- NEAR MISS — water standing in the bottom at the end of the cycle — That is drainage, not washing, and it belongs to the drainage page for this family.
Causes, most likely first on the SHX family
- The filter assembly and sump screen are loaded with soil — Ranked first on this family, and it stays first whatever generation of the code you own: the fine filter is designed to be removed by hand, which is exactly why it is the part owners never touch.
- A spray arm is blocked, or the load stopped it turning — Second. Jets clog with the same soil the filter missed, and older units accumulate scale in the jets as well as debris.
- The water arriving is not hot enough, or the fill is restricted — Moved up the list on a family whose codes span several build generations: the inlet valve screen silts up and the tap under the sink stiffens with age, and both starve the fill.
- Rinse aid is empty, or the dispenser setting is too low — Ranked here, and it explains the wet half of the complaint outright.
- The heating circuit or its sensor has failed — Last, and that is the point of the order. It is the least likely of the five and the only one that needs a technician, so it is the one you reach by elimination rather than by guess.
Check in this order, and why
- Pull the filter and look through it — It twists out by hand, no tool. Hold it to a light: if the mesh is blind, rinse it under a hot tap with a soft brush and run one short cycle empty before you judge anything else.
- Spin both spray arms by hand, then check their jets — They should turn freely through a full circle with the racks in place.
- Run the kitchen tap hot, then start a cycle — Starting with hot water already at the tap removes the longest variable in the wash.
- Open the rinse-aid cup and the detergent cup — Fill the rinse aid if it is empty; note whether the detergent cup shows residue from the last cycle, which tells you the dispenser did not open or the water was cold.
- Only now judge the heating circuit — If the filter is clear, the arms turn, the rinse aid is full and hot water is arriving, and the load is still wet and dirty, the heating circuit is the remaining candidate and it is a service call.
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
Isolate the machine at the breaker before the toe-kick or any panel comes off; a capacitor can hold a charge after the power is off. The sump collects glass chips that are invisible under water, so use a glove and a light.
When to call a technician
The line on this family is the toe-kick. Everything above it — filter, arms, dispenser, racks, the supply valve under the sink — is an owner job that needs no tool and no part.
