SOLVED: Dishwasher Leaving Gritty Residue: Overviews

When people buy dishwashers, they all hope that the appliances would save them time and effort while doing the dishes. As a result, many homeowners have a hard time accepting issues such as dishwasher leaving gritty residue on the dishes. With dishes coming out of the dishwashers covered in gritty residue, their owners must re-wash them which is annoying. Needless to say, causes of gritty residue and solutions for them capture the interest of those that use dishwashers regularly.

Why Dishwashers Leave Gritty Residue On The Dishes 

Which Style of Dishwasher Is Right for You?

Frustrated by the fact that your dishwasher keeps leaving gritty residue on your dishes and want to put an end to that? If that is the case, this article is going to be of use to you. Down below is all the information that you should know regarding gritty residue and dishwashers.

Full Filter 

In layman’s terms, the filter of dishwashers is there to collect food particles falling out from dishes during wash cycles. If homeowners clean the filter from time to time, it’s going to make sure that the dishes stay free of food particles throughout washing cycles. On the other hand, if people neglect the filter, it would become full soon and that means nothing could keep food particles away from dishes. Hence, if you notice your dishwasher leaving gritty residue on the dishes, full filter is the first suspect.

Dirty Bottom 

As dishwashers wash dishes, the filter usually collects most of the food particles but a portion may sink to the bottom. Over time, food particles should accumulate at the bottom to the point that they kick up every time people start a washing cycle. Naturally, with food particles flying all over the place, dishes inevitably come across some and end up with gritty residue. Assuming that dirty bottom is responsible for gritty residue on your dishes, the situation won’t improve unless you take proper measures.

Blocked Spray Arms 

The spray arms of dishwashers play a key role in the washing cycles so if they get blocked, the washing efficiency suffers. Therefore, you need to think about spray arms if you find gritty residue on your dishes after taking them out of the dishwasher. Plenty of issues can lead to blockade in the spray arms from build-up of food articles to careless dish arrangement. It’s a good idea to check out the owner’s manual before inspecting spray arms to familiarize yourself with their characteristics.

Subpar Detergents

Modern dishwashers accept a wide range of detergents but certain detergents don’t work as well as others. If you add subpar detergents into your dishwasher, there is a chance that food articles remain stuck on the dishes following washing cycles. Furthermore, detergents with low quality may even fail to dissolve completely which adds grimes to the dishes. Because of that, if you happen to get the detergent for your dishwasher on the cheap, it could be the one at fault.

Poor Choice Of Cycle

A lot of homeowners tend to choose quick washing cycles regardless of the number of dishes in their dishwasher. That habit works well on small loads of dishes but as the size of the load increases, the odds of dirty dishes rise. You keep selecting quick washing cycles as your dishwasher needs to wash full loads of dishes? Then your choice of cycle is the one behind the appearance of gritty residue on your dishes.

Nowadays, once it comes to dishwasher leaving gritty residue on the dishes after washing cycles, quite a few fixes exist. That being said, if you wish to get your dishwasher back to normal as soon as possible, you should try these tips and tricks.

Clean The Filter

In the beginning, remove the filter from your dishwasher, soak it in hot water and wait an hour. Next, use a brush to scrub the filter to get rid of the leftover food particles. When the filter looks good, return it to the dishwasher, load a couple of dishes and start a test cycle. If things proceed smoothly, your dishes would come out all clean and shiny.

Wash The Bottom

Grab a piece of cloth, soak it in soapy water and wipe the bottom of your dishwater. In the case that the accumulation of the food particles proves more stubborn than expected, run an empty hot cycle. It’s worth pointing out that vinegar, baking soda and so on could also help dislodge the food particles in times of need. The moment food particles disappear from the bottom, you may rest assured knowing that you no longer have to deal with gritty residue.

Process The Spray Arms 

Use the owner’s manual to locate the spray arms of your dishwasher and remove them from their position. Afterward, soak the spray arms in vinegar for a bit then pull out the loosened food particles with a wire. In the next step, return the spray arms to where they belong before loading in dishes for a test cycle. However, as you load the dishes, you should pay attention to the dish arrangement to ensure that the spray arms don’t get blocked.

Change The Detergent 

If you suspect that your detergent is the cause of gritty residue, just change to another detergent and see how things turn out. Your dishwasher stops leaving gritty residue on the dishes following the change of detergent? If that is the case, your original detergent is probably not up to the task and you must stop using it. Nonetheless, to be thorough, you have to give associated issues some thought such as the amount of detergent, the state of detergent dispenser, etc.

Adjust The Cycle 

For small loads of dishes, you could use quick washing cycles to cut down water consumption. Still, if you have to wash a lot of dishes, stick to long washing cycles for the best result.

  • Keep the door open: At the end of every washing cycle, you should keep the door of your dishwasher open for a while. By doing so, you can accelerate ventilation, remove moisture and inhibit the growth of mold.
