Dishes Coming Out Gritty or Spotted: Filter, Spray Arms and Rinse Aid

Dishes coming out gritty are plates and glasses with sandy specks, dried food, a white film or spots after a full cycle, often worse on the upper rack or in one corner.

What it
usually means.

A dishwasher cleans by spraying the same small amount of water over and over, and it relies on a filter to keep that water clean. When the filter at the bottom of the tub is packed, the pump sprays food particles back onto the dishes, and grit lands mostly on the upper rack and inside glasses. When a nozzle on a spray arm is blocked with a seed, a flake of scale or a bit of label, one strip of the rack is left dirty every time. Hard water adds a white film and spots that no amount of scrubbing removes, and an empty rinse aid dispenser makes spots worse. Loading matters too: a tall pan in the wrong place blocks an arm from turning, and plates facing away from the spray stay dirty. The detergent dose and the water that arrives first, often cold if the kitchen is far from the water heater, change results as well. Almost all of this is upkeep: the filter cleaned, the spray arms cleared, the hardness and rinse aid set, and a few loading habits changed. If the machine does not heat its water, does not drain or its wash pump has weakened, a part has failed; that is a repair for the sister dishwasher repair site.

The 6 causes, cheapest first

Answer these first

01

Is it gritty specks, dried food, a white film or water spots?
02

Is it worse on the upper rack, the lower rack, or one area of either?
03

When was the filter at the bottom of the tub last taken out and cleaned?
04

Does each spray arm turn freely by hand, and are its holes open?
05

Is the rinse aid dispenser full, and is the water hard where you live?

Check these
before you book.

Dishes coming out gritty: 5 checks, and none of them costs anything.

01

Twist out the filter at the bottom of the tub and look at how much food and film it holds.

02

Spin each spray arm by hand, then hold it to the light and look for blocked holes.

03

Fill the rinse aid dispenser, and check the detergent dose against the hardness of your water.

Also worth checking

  • Run the kitchen tap until it is hot before starting a cycle.
  • Look at the tub after a cycle: standing water means the drain needs attention.

How soon does it need a visit?

Gritty or spotted dishes are not urgent. Clean the filter yourself today, and book a dish care visit if results do not improve, if the arms are blocked or damaged, or if water stays in the tub.

The causes,
cheapest first.

6 things dishes coming out gritty or spotted: filter, spray arms and rinse aid turns out to be, from loading that blocks the spray to heater, wash pump or drain failing.

The cost guide
  1. 01 no service

    Loading that blocks the spray

    A tall pan or a board can stop a spray arm or shade a whole row. Spin each arm by hand after loading, and face dirty surfaces toward the center.

    No service: check it yourself
  2. 02 no service

    Rinse aid empty or detergent dose off

    Without rinse aid, water dries in spots; with too little detergent, food stays on. Fill the dispenser and use the dose on the detergent for your water hardness.

    No service: check it yourself
  3. 03 lowest

    Filter packed with food

    A clogged filter lets the pump spray dirty water back onto the dishes. The filter is lifted out and cleaned with a soft brush, and the sump below it wiped clear.

    Fixed by dish care filter and spray arm cleaning On a dish care machine
  4. 04 lowest

    Spray arm nozzles blocked

    Seeds, glass chips and scale in the nozzles leave the same area dirty every load. The arms are taken off where the design allows and each hole is cleared with a plastic pick.

    Fixed by dish care filter and spray arm cleaning On a dish care machine
  5. 05 low

    Hard-water film and scale

    Minerals leave a white film on glasses and scale on the heater and the arms. The hardness setting is adjusted, and a descaling treatment is run with a product the maker allows.

    Fixed by water filter and descaling service On a dish care machine
  6. 06 moderate

    Heater, wash pump or drain failing

    Water that never gets hot, a weak spray or water left in the tub after the cycle points to a failed part. That is a repair for the sister dishwasher repair site.

Questions about
dishes coming out gritty or spotted: filter, spray arms and rinse aid.

Should plates be rinsed before they go in?
Scrape them, but most makers advise against a full rinse. Modern detergents work on food, and sensors in some machines use the dirt level to set the cycle. Scraping keeps the filter from clogging as fast.
Why do glasses come out cloudy even after a good wash?
Usually hard-water film, which rinse aid and the right hardness setting reduce. If the cloudiness cannot be wiped off with vinegar, the glass may be etched, which is permanent and comes from soft water with too much detergent.
Does a filter clean take long?
A few minutes. Take out the lower rack, twist the filter out, rinse it under warm water with a soft brush, and lock it back in fully. A filter left loose lets food past into the pump.
Why is only the upper rack dirty?
The upper arm or the spray tube that feeds it may be blocked, or the rack may be set too high for water to reach. A packed filter also shows first on the upper rack, which gets the dirtiest water.
