The short answer
Poor cleaning and wet dishes are two different complaints that share one page because they share three causes on the SGE family: soil recirculating through a loaded filter, a spray arm blocked by the load, and rinse aid that ran out. The fifteen codes in the table cover more than one build generation, so match your own code against it before a panel comes off.
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.
- A white chalky film on glassware — Wipe a glass with a little vinegar. If the film lifts, it is mineral deposit — hard water with too little detergent or no rinse aid.
- Detergent still sitting in the dispenser at the end of the cycle — Either the cup never opened, or a tall item on the upper rack blocked it, or the water never got warm enough to dissolve the tab.
Causes, most likely first on the SGE 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.
- The detergent is wrong, stale or badly dosed — Detergent loses activity in a cupboard, and hard water eats the dose before it reaches the dishes.
- 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.
- Reload the racks and run the same load again — Nothing over the dispenser, nothing lying flat, cutlery alternated. A wash that comes out clean on the second run was never a machine fault.
- 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 SGE 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 fifteen codes fall into four 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 off the breaker before removing the toe-kick or the access panel; a capacitor can hold a charge after the power is off. Treat the sump as sharp — glass chips collect there and are invisible under water.
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.
