--- title: "Dishes come out dirty or gritty" description: "Maytag dishes come out dirty or gritty: poor cleaning is rarely one thing that broke and usually three small things that added up." url: "https://maytagmiami.support/symptoms/dishwasher-dishes-not-clean/" date_modified: "2026-09-07" Appliance type: "Dishwashers" --- # Maytag dishes come out dirty or gritty ### Three checks in the right order Run the kitchen tap hot until it is genuinely hot, then start the dishwasher — a machine that begins with a tub of cold water spends half its cycle catching up and never quite does. Next, spin both spray arms by hand. They should turn freely and every hole should be clear; hold one up to the light and look through the holes, because scale from this water closes them gradually. Third, take out the filter and rinse it. If dishes are gritty rather than filmy, that filter is the likeliest single cause on the whole list. ### What it usually means, by the kind of machine One complaint, several machines. This maker still sells a top-load washer with an agitator alongside one without, a front-loader, and a stacked pair, and it sells the same oven as a range and as a wall unit in gas and in electric. The behavior you can describe is identical on all of them; the first hour of the repair is not. A front-load washer has a drain filter the owner can open and a top-loader has nothing to reach from the front, and that single difference decides how the same afternoon goes. - **Front control** — Cycle options live behind buttons on the front edge and it is easy for a heavy cycle to have been switched off without anybody noticing. Worth checking what setting the machine is actually running. - **Top control** — Same machine, and the same first three checks. The one addition is that a top-control panel is easy to press with a hip while loading, so an unexpected light cycle happens more often here. ### Which dishes tell you which part The pattern is the diagnosis. Poor cleaning that is worse on the upper rack points at pressure reaching the top arm. A single quarter of a rack coming out dirty points at a blocked section of one arm or something obstructing its rotation. Everything equally poor across both racks points at temperature, detergent or the filter — and those are the three an owner can address without anybody visiting. ### Scale, quietly The water in this region leaves a deposit, and dishwasher spray arms are where it shows first. A machine that cleaned beautifully for six years and has slowly declined has usually lost half its jets rather than any part, and clearing them restores it. That is worth knowing before a working machine gets replaced. ### Habit against repair Three of the five causes on this page are things anybody can change this evening, and we would rather say that than book a visit for a machine that is working. Hot water at the start, a spray arm that turns freely, and a filter that has been rinsed will restore a great many dishwashers to how they washed when they were new. If all three are genuinely in order and the dishes are still poor, then it is a repair, and it is a specific one rather than a guess. Water not hot enough at the start The machine heats what it is given, and starting cold costs it most of a cycle. Running the tap first is free and it fixes a surprising number of these. Blocked spray arm holes Scale and debris close them one at a time, and the dishes in the affected quarter of the rack come out dirty while the rest are fine. A filter that needs cleaning Recirculated water carries the debris straight back onto the load. Grit on glasses is the signature. Loading and detergent Overlapping plates block the spray, and old or clumped detergent does not dissolve. Both are real causes and neither is a repair. The wash pump or the heater What is left after the first four. A machine that cannot raise water temperature or cannot get pressure to the upper rack is a genuine repair rather than a habit. Run the tap hot first Thirty seconds at the sink before pressing start. Free, and it changes the whole cycle. Spin both arms They must turn without catching. Anything in the rack stopping one of them is the cause of a whole dirty rack. Hold an arm to the light Look through the jets. Closed holes are visible and they are cleared with a piece of wire. Note which dishes are dirty Consistently the top rack, or one corner, points at spray. Everything equally dirty points at water or filter. Film, grit or food left on everything after a full cycle What it usually means Hot water has to reach the machine before the cycle starts, not during it A spray arm that cannot turn freely leaves a predictable pattern of dirty dishes Grit on everything usually means the filter, not the pump Three checks in the right order Run the kitchen tap hot until it is genuinely hot, then start the dishwasher — a machine that begins with a tub of cold water spends half its cycle catching up and never quite does.

That is scale rather than dirt, and it responds to rinse aid and a cleaning cycle far better than to a repair. If it persists after both, the water temperature is the next thing to look at. ### Do I need to rinse dishes first? Scrape, do not rinse. These machines expect some soil to work against, and a completely pre-rinsed load can actually wash worse. What they do not expect is bones, labels and lemon seeds. ### It only started after we changed detergent. Then change it back before booking anything. Tablets that do not dissolve fully in a shorter cycle are a common and entirely fixable cause. --- **[Read full article: Dishes come out dirty or gritty](https://maytagmiami.support/symptoms/dishwasher-dishes-not-clean/)**
