Start here
BDDIT models take this one slightly differently. Start at the bottom of the tub. A filter packed with food fragments starves the pump, and a starved pump cannot drive the upper arm, which is why the top rack is usually the first to show dirt. The departure from the generic page is in where the first check goes.
What you observe on a BDDIT unit
- Grit and food fragments left on the plates — The filter is not holding what it catches, so debris is being recirculated onto the load. Read this one against the BDDIT models listed below.
- The top rack is dirty while the bottom rack is clean — The upper spray arm is not getting pressure or is not turning, which is a blockage story.
- The load is wet as well as dirty at the end — A cycle that has not heated properly leaves both, and that points at the heater or the incoming water.
- Cloudy glasses that do not wipe clean — Etching, which is permanent and is caused by soft water and over-dosing rather than by a fault.
- NEAR MISS: water is left standing in the bottom at the end — That is a drainage fault, and the drainage page is the one to read first.
Causes in likelihood order on the BDDIT line
- A filter packed with food debris — Ranked first and it is not close. The filter is the one part of this appliance the owner is expected to clean, and it is the one part almost nobody does until the results go wrong. On the BDDIT models this stays at the top because nothing about the platform makes it less likely.
- A spray arm that cannot turn — Second: a tall item hanging through the rack, or a bearing full of grit, and the arm simply stops sweeping.
- A failed circulation pump or wash motor — Last, and deliberately: it is the least common and the only one that is not owner work. It is diagnosed by elimination, not by guess.
Where to start, and why
- Pull the filter out and look at it — It takes seconds, needs no tool on most machines, and it is the single highest-yield check on the whole list. The BDDIT layout is the reason it comes first here.
- Spin both spray arms by hand — They should turn freely with a light push. Resistance or a stop is the fault, right there.
- Check the detergent dispenser door opens freely — A tall item leaning on it holds it shut for the whole cycle, and the load comes out as though no detergent were used.
- Check the rinse-aid reservoir and the detergent date — Cheap to rule out, and it explains film and spotting rather than actual dirt.
Isolate it first
Safety
Isolate the appliance at the plug or the breaker before any panel comes off. The tub and its contents stay hot for a while after a cycle, so let it cool before reaching in. Treat every filter clean as a search for glass fragments.

When to call a technician
The owner side of this fault covers everything you can reach inside the tub. Call when the fault is outside that, and call the same day if the cycle finishes hot but the dishes are stone cold, which suggests the heater is not working at all.
