If we open the dishwasher after a full cycle and find gritty residue stuck to glasses and plates, it’s frustrating. We expect clean dishes, not a second mess to deal with. This issue usually comes from something minor that’s either overlooked or gradually built up over time. Therefore, learning what to check first helps us avoid repeat problems and unnecessary calls.
To clarify, this kind of grit is often food bits, mineral residue, or soap scum. Most of these can be traced back to cleaning habits, water quality, or mechanical issues inside the machine. Below, we’ll walk through practical ways to figure out what’s going on and what to do about it.
Clean the Filter First
We always start by checking the dishwasher filter. This is the part that traps food debris during the wash cycle. However, if it’s full, water won’t circulate properly and particles will redeposit on dishes. Most dishwashers have the filter at the bottom under the lower rack.
Firstly, we remove the bottom rack and twist or lift the filter out depending on the model. Secondly, we rinse it under warm water using a soft brush or toothbrush. If there’s any sticky grime, a little dish soap helps. In addition, we inspect the area underneath for hidden buildup that could restrict drainage.
Once the filter is back in place, we run an empty cycle with hot water to flush out any lingering debris. This simple step alone can dramatically reduce gritty results.
Inspect the Spray Arms
The spray arms shoot water at high pressure to clean the dishes, but small food particles can clog the tiny holes. As a result, dishes on some levels may get partial cleaning. We can usually remove the arms by unscrewing or unclipping them.
To clarify, we hold the spray arm under running water to see if it flows out of each nozzle evenly. If not, we use a toothpick or needle to dislodge any clogs. Soaking the spray arm in white vinegar for 30 minutes also helps break down hard water buildup that we may not see.
After reattaching the spray arms, we manually spin them to make sure they move freely. If they’re stiff or stuck, cleaning alone might not fix the issue. In that case, a replacement may be needed.
Use the Right Amount of Detergent
More soap does not mean cleaner dishes. In fact, using too much detergent can leave behind cloudy film and gritty residue. Especially if we have soft water, overuse leads to leftover suds that cling to plates and glasses.
For instance, we should check the detergent cup to see if it’s still full at the end of the cycle. That’s a sign it’s not dissolving properly. Using fresh detergent and following the package’s recommended amount works better than guessing. Meanwhile, pods are convenient, but they still depend on water temperature and cycle length to dissolve fully.
Another tip: if we store detergent in humid areas, it clumps and loses its effectiveness. Keeping it dry helps it last longer and perform better.
Make Sure Water Is Hot Enough
Dishwashers need hot water to clean well and dissolve detergent completely. If the water isn’t hot enough, food bits don’t break down and detergent residue gets left behind. Most dishwashers require water to be at least 120°F to work properly.
To test this, we run the hot water at the kitchen sink and use a thermometer to check the temperature. If it takes too long to heat or never gets hot enough, we may need to adjust the water heater or fix a plumbing issue.
In addition, we can run the kitchen tap for 30 seconds before starting the dishwasher. That way, the first cycle starts with hot water instead of cold, which improves performance from the beginning.
Load the Dishwasher Correctly
It’s easy to overlook, but how we load the dishwasher affects how well it cleans. If dishes block the spray arms or are stacked too closely, water and detergent can’t reach every surface. Consequently, we end up with half-clean dishes and leftover debris.
We make sure cups and bowls face downward and that nothing nests together. Utensils should be mixed and spaced out in the basket. Large items like baking sheets or pans should go on the sides or back, not across the front where they block the detergent dispenser.
Above all, we avoid overloading the dishwasher. It’s tempting to squeeze in one more plate, but that often leads to gritty results across the whole load.
Check for Drainage Problems
Sometimes gritty dishes are a sign that dirty water isn’t draining properly between cycles. If water pools in the bottom of the dishwasher after the cycle, this needs immediate attention. We begin by checking the filter again, but also inspect the drain hose and air gap for clogs or kinks.
If we smell a foul odor or see visible standing water, we know the dishwasher is not clearing out the dirty water. As a result, it may be washing the dishes in used, food-filled water.
To rule this out completely, we run a rinse cycle and then open the machine to see if water drains as expected. If not, we may need professional help with the drain pump or plumbing. In these cases, reaching out for dishwasher repair in Burbank may be the most efficient solution.
Use a Dishwasher Cleaner Monthly
Even if everything looks clean on the surface, mineral deposits and hidden food residue can build up over time. Therefore, we make it a habit to use a dishwasher cleaning product once a month. These cleaners break down grease, limescale, and detergent scum in places we can’t reach.
We simply run the cleaner on an empty hot cycle according to the product instructions. This also helps maintain the spray arms, sensors, and drainage components so they continue to work as intended.
In addition, vinegar or baking soda can help for light cleanups, but commercial cleaners are more effective for deep buildup, especially in areas with hard water.
Avoid Pre-Rinsing Too Much
It might seem logical to rinse off all food before loading dishes, but modern dishwashers are designed to detect soil levels and adjust cycles. If we pre-rinse everything completely, the sensors may think dishes are already clean and shorten the cycle, leaving behind grit or residue.
Instead, we should scrape off chunks of food but leave a little residue so the dishwasher knows to run a full cycle. This also prevents detergent from working too aggressively on a nearly clean surface, which can lead to filming or spotting.
At the same time, we avoid putting heavily soiled dishes in without any prep. A quick scrape goes a long way in achieving better results.
Look for Mechanical Issues
If we’ve tried all the basics and dishes are still coming out gritty, we may be dealing with a worn-out part. Over time, circulation pumps, heating elements, and float switches can fail. These mechanical issues affect water flow, temperature, and cycle performance.
For example, a weak pump may not provide enough pressure for spray arms to clean properly. A malfunctioning float switch may not let in enough water for a full wash. These are harder to diagnose without opening up the unit.
In cases like these, we recommend seeking help from a team experienced in appliance repair in Burbank. A proper diagnosis saves us from replacing the entire unit unnecessarily.
Don’t Ignore Signs That Persist
We sometimes hope the problem will fix itself on the next cycle. However, if dishes are consistently gritty, ignoring the issue can lead to long-term damage. Hard water deposits may clog more parts, or motors may strain against blocked systems.
We take time to review our habits and make changes, but we also know when it’s time to get help. If we’ve already cleaned the filter, spray arms, and checked temperature, it’s a good idea to speak with someone who can spot what we can’t.

Frequently Asked Questions
Why do my dishes still feel gritty after running a full cycle?
This is often due to a dirty filter, clogged spray arms, or detergent buildup. It can also happen if water isn’t draining properly or the water temperature is too low during the cycle.
Do I need to rinse my dishes before loading the dishwasher?
Not completely. It’s better to scrape off excess food but leave some residue. This helps the dishwasher sensors run a full cycle and lets the detergent do its job more effectively.
How often should I clean the dishwasher filter?
We recommend cleaning it every two weeks if the dishwasher is used regularly. More frequent use may require weekly cleaning to prevent clogs and keep dishes fully clean.
Can hard water cause gritty residue?
Yes, hard water can leave mineral deposits on dishes, especially if detergent isn’t dissolving properly. A water softener or dishwasher cleaner may help reduce the problem.
What’s the best cycle to use for dirty dishes?
Heavy or pots and pans cycles are best for dishes with baked-on food or grit. These cycles use higher water temperatures and longer wash times to ensure a deep clean.
