Dishwasher Not Cleaning Dishes in Houston, TX
Dishes coming out with food residue or a filmy coating despite a full cycle usually points to a specific mechanical or water-related issue rather than the dishwasher failing entirely.
What Usually Causes This
If dishes near the bottom are cleaner than dishes on top (or vice versa), it often points to a specific spray arm not rotating properly, while overall poor cleaning across the whole load points more toward water temperature or pump pressure.
Common causes
- A clogged or blocked spray arm
- Water temperature that's too low to properly clean
- A failing wash pump not circulating water with enough pressure
- An overloaded or improperly loaded rack blocking spray arm rotation
- Hard water mineral buildup on internal components
Safe checks you can do first
- Check that spray arms spin freely by hand and aren't blocked by tall items in the rack
- Run your kitchen faucet's hot water before starting the dishwasher, so it starts with hot water rather than cold
- Clean the dishwasher's filter, which can restrict water circulation when clogged
When Professional Repair Makes Sense
If cleaning the filter and checking the spray arms doesn't improve results, the wash pump or a water temperature issue likely needs a technician's diagnosis.

Yes — mineral buildup from hard water can coat spray arms, heating elements, and interior surfaces over time, reducing cleaning performance.
This is usually a loading or spray arm blockage issue rather than a full dishwasher failure, since properly positioned items in the water's path clean normally.
