DIY Tips to Keep Your Dishwasher Air Gap Running Smoothly

One of the most common plumbing mistakes in a home is the lack of the air gap or drain loop by the dishwasher. That lets kitchen sink wastewater enter the dishwasher, so you won’t want to wash your dishes with dirty water.

dishwasher air gap is a fitting mounted about two inches above the sink that prevents contaminated water from re-entering the dishwasher from the drain via backflow. An air gap is a simple way to make certain wastewater and contaminants never re-enter your clean water supply.

It’s possible you’ve never heard of a dishwasher air gap, but it plays an important role in keeping your dishwasher operating properly and protecting your family’s health.

So, what exactly does a dishwasher air gap do? Put simply, it prevents drain water from backing up into your dishwasher and contaminating your freshly washed dishes with dirty drain water.

When the dishwasher is discharging water, a lot of water floods out of the air gap. … When the gap leaks, it is normally due to a kink or blockage in the tube from the air gap to the tail piece (drain line) below the sink. The gap may need to be cleaned, or the drain line below the sink may be plugged.

This is how the Dishwasher air gap works:

  1. The air gap is usually located right by your kitchen faucet.
  2. The water discharge from to dishwasher, and goes up in a loop in the air gap, and falls down in the sink trap.
  3. The air gap should not leak, but it is normal to hear gurgling as the water goes through the loop.
  4. If you don’t have an air gap you would want to look underneath your sink to make sure you have a loop on your drain hose. Your dishwasher drain hose needs to be higher than the sink drain.

The drain hose that goes from your dishwasher to the drainpipe or garbage disposal should have a loop and be mounted higher than the sink. Very often the drain hose goes in slop from the dishwasher to the drainpipe, that is an improper way and you will very likely get kitchen wastewater in your dishwasher.

Picture your kitchen faucet and sink. If the sink drain becomes clogged and water backs up into the sink, that water can’t reach the faucet outlet because of the “air gap” separating the two.

The faucet outlet is always higher than the rim of the sink, which creates an air gap between the two. The backed-up sink water won’t reach the faucet outlet and contaminate your water supply.

The same principle applies to your dishwasher air gap. The device is usually a small cylinder sitting on your cabinet top near the sink and faucet. As your dishwasher cleans your dishes, the wastewater is pumped out of the dishwasher and carried by a hose to the air gap.

Like your faucet opening above the sink, the outlet from the dishwasher hose in the air gap is higher than the opening to the drain hose leading away from the device. As with the faucet and the sink, an air gap separates the two hoses.

If you still are having problems with dirty dishes there is a couple of other simple things you can try:

  1. Run your kitchen sink on hot water until the water that comes out of the faucet is really hot, then start the dishwasher.

Think of when you start to run your faucet on hot, it usually doesn’t come out as very hot right away. That is the same for the dishwasher as well.

Doing this prevents cold water from entering the dishwasher, and as you know cold water does not do as good as hot water when it comes to cleaning.

2. Try to change your soap

Conclusion:

Using a bottle brush, simply extend it down the air gap (not the line from the dishwasher, but the line leading into the disposal) and twist it until the debris in the line comes loose. Or, with a wet/dry vac, place the hose over the air gap, turn it on, and wait forty seconds to a minute.

If everything works properly, the dishwasher pumps wastewater to the air gap where it’s moved away by the drain hose to the garbage disposal. And the air gap separating the openings of the two hoses normally prevents wastewater from backing up and contaminating your freshly washed dishes. You can find an illustration of a dishwasher air gap here.

DIY Tips to Keep Your Dishwasher Air Gap Running Smoothly 2022

Things do not always work as they should, however, and a clogged air gap can create a huge mess in your kitchen, as shown in this video. If water is flowing or gushing out of the air gap, there are some DIY solutions you can try to correct the problem.

DIY Tips to Keep Your Dishwasher Air Gap Running Smoothly in 2021

  1. One involves a roll of paper towels. Remove the cover of the air gap, place the paper towel tube over the hose openings and blow into the air gap. This may remove food particles interfering with the normal water flow.
  2. If this technique doesn’t work, use a long-handled bottle brush to dislodge food particles or other debris that may have jammed the drain hose.
  3. If either your garbage disposal or dishwasher has been recently installed, it’s possible the installer forgot to remove the “knockout plug” on the disposal unit. To fix this, detach the hose linking the air gap drain hose to the disposal. Take a hammer and screwdriver and tap the knockout plug that’s preventing water from draining into the disposal. Then reconnect the drain hose to the disposal. Finally, unplug the disposal, reach inside it and remove the knockout plug.

If none of these tricks work, you may need to have a plumber snake out your drain lines to remove debris you can’t reach. Calling in the professionals can be expensive. To help avoid these high repair costs, consider purchasing a home warranty from American Home Shield.

Prewashing the dishes with water before putting them in the appliance is the first.

Do you want to know how long your appliance will last? look at the brand.

Although it is always said that doing it yourself is better in every way, experts indicate that washing by hand is less ecological and economical than doing it in the dishwasher

Josep Freixa, the representative of Winterhalter dishwashers and industrial washing systems in Catalonia, Aragon, Andorra, and the Balearic Islands, is clear: “When we wash them by hand, we spend much more water almost without realizing it, and we do not achieve such effective hygiene.” 

Cristina Cusí, professor of Food & Beverage at the ESHOB Barcelona Higher School of Hospitality, adds that the water in the machine reaches temperatures higher than what the hand can withstand, favoring total disinfection.

They convince us. We will buy it, and we find that there are different types, sizes, and budgets in the market. Do we know which one to choose? Do we believe it is expensive or better a cheap one? And, once we have it at home, do we know how to get the most out of it? Do we place the cutlery and pots well? Should we always use salt? How do we clean it?

If you continue reading, you will discover curiosities such as why we have drop marks on the glasses and the natural function of the rinse aid, which is used for more than just making the dishes shine. Above all, you will know the ten basic mistakes to avoid when washing pots in the dishwasher.

1. Prewash dishes with water before putting them in the dishwasher

“It makes no sense to remove food remains from the crockery by putting it under the stream before entering the dishwasher because we will use twice as much water,” Cristina Cusí, a teacher at the ESHOB school in Barcelona. 

But the dishes must enter the machine as clean as possible, “because the dishwasher can deal with stains and grease, but it is not a waste shredder if this enter, they accumulate, we will have bad results, and they can clog it,” says Josep Freixa, an expert in industrial dishwashers and representative of the high-end German brand, Winterhalter.

It is not necessary to prewash the dishes with water before putting them in the appliance, but it is advisable to remove the food residues.

Therefore, we must remove the visible remains with a fork or hand, following the maxim that “the less dirt on the dishes, the better they will be.” Cusí recommends pastry tongues (rubber spatulas), scraping very stubborn grease, and dragging gunk off plates and utensils.

2. Not adapting the type of dishwasher and the number of washes to my needs

There are various ranges, categories, and sizes in the domestic market, but the key is in their use. “Which consumes less to put a large dishwasher full a week or a small one daily with a low load?” asks Freixa. It sounds logical to think that the first option is good, and we are right. The expert considers that a couple without children may find it more economical to place the dishes in the dishwasher and start when it is complete (without overflowing, of course). “We have to use common sense and not spend many days with dirty dishes inside the appliance,” she points out and recalls the importance of placing them clean of residue.

What if we don’t have enough crockery? “It pays more to buy more because there are excellent prices than to use the dishwasher more times than necessary.” The best advice is that everyone adapts the dishwashing to their circumstances and needs, bearing in mind that it will always be more sustainable, efficient, and economical to fill it within the established limits than to use it half empty.

3. Save on the purchase of a dishwasher because what is cheap is expensive

Josep Freixa has verified that buying a quality dishwasher always pays off in his professional practice. On the one hand, a suitable device lasts longer and consumes less energy; on the other, it also cleans more effectively. “If we could see a dishwasher with glass walls, we would see how the water reaches all corners much better in a good appliance from a recognized brand than in a low-quality one,” he says. Because everyone can see when a plate is dirty, it is impossible to check hygiene with the naked eye because bacteria are invisible to the eye. “You can save 500 euros on the purchase, but you will get a worse result and more electricity costs,” says the expert.

Higher temperature washing programs consume more energy. To avoid this, we can use the so-called Echo.

Likewise, washing programs with higher temperatures consume more energy. To avoid this, we can use the so-called Eco, “which achieves the same cleaning effect with less heat and water intensity, lengthening the wash’s time.”

4. Thinking that the rinse aid only makes the dishes shine

Although it is called that rinse aid, this substance that we incorporate with the detergent in each wash has two primary functions and leaves the words with a shiny point. 

The first is to reduce the amount of water that remains on the dishes by accelerating the drying process at the end of the wash, “especially noticeable in industrial dishwashers that clean the dishes in just 2 minutes with water pressure and a very powerful temperature”, says the delegate of the Winterhalter brand, with more than 70 years of specialization in this product for the hotel industry.

Secondly, it neutralizes the effect of the detergent if there is any residue left in the rinse. It also combats watermarks and, in some cases, creates a kind of protective film that makes the dishes look shiny. Hence the name, although in Latin American countries, they call it dry.

5. Do not add salt to remove limescale in areas where the water is very hard.

In the Mediterranean basin, where the water has a lot of lime, it is mandatory to add descaling salt to the dishwasher in the hole indicated. “If we don’t do it, the resistance (an element that heats the water for washing) will be covered with limescale. It will get hotter than it should, lose effectiveness, and consume much more electrical energy and it will end up breaking down. The result will also be that the pottery will worsen,” explains Freixa.

In areas such as the Mediterranean basin, where the water has a lot of lime, it is mandatory to add descaling salt to the dishwasher in the indicated hole to do so.

For the specialist, if we think that, since electrical appliances have a limited life, perhaps we shouldn’t spend on salt and save to buy a new one when the one we have fails, we are wrong. “It is better to do what we can to keep our machine in good condition and perform as well as possible,” says the expert. In the case of living in areas where the hardness of the water is much lower (the mineralization is weaker), it will not be necessary to add salt. In addition, the effectiveness of detergents will always be greater the less complicated the water is.

The marks in the form of drops that remain on glasses and crystal glasses after washing are not just traces of lime, as we often think.

6. Place the cutlery with the handle up and stack the plates

When we talk about the distribution of the elements in the dishwasher, we must follow the manufacturer’s disposition. The enormous pots should be placed in the lower rack of the dishwasher because it is the place with the most space available, not because the water reaches it better there, with a thicker jet, as can be read in some articles on the Internet. “If the dishwasher is of quality, the water should arrive perfectly and with the same force equally to all corners of the machine,” says Freixa.

The importance of water (along with the detergent) is crucial for a good wash. For this reason, we must make sure “that the utensils do not bunch up, that one does not cover the other, preventing them from being washed,” says Cristina Cusí from the ESHOB school. “It’s like playing Tetris,” explains Freixa and adds that it is essential to place the cutlery in its bowl with the handle downwards to correct wash the cutlery’s dirtiest parts and let the water circulate, something necessary in the passed. “Current dishwashers from good brands have a third upper tray to place the cutlery comfortably and obtain a better washing result.”

We have to place the utensils in the dishwasher without piling them up and the cutlery with the handle down.

7. Put refined glasses in the dishwasher

The glasses and cups can be put in the dishwasher as long as they are spaced and do not move because they could break by bumping into each other. 

In the case of delicate glasses, it is advisable not to insert them and opt for handwashing because, being made of thin glass, they are more at risk of being damaged.

The marks in the form of drops that remain on glasses and crystal glasses after washing are not just traces of lime, as we often think. “There are also traces of minerals in the water that we can avoid by using osmotic water free of lime and mineral, which is unusual in a domestic installation,” explains the dishwasher expert. The water purified by osmosis is the one that has been treated and filtered to be free of substances such as chlorine, calcium, magnesium, iron, potassium, etc. “No need to worry; it is not dirt.”

8. Hand dishwashing detergent sneaking in.

It seems silly, but it is not advisable to enter detergent intended for washing dishes by hand in the dishwasher. “Each one is conceived for its specific function, and they have nothing to do with each other.” But, does anyone think of putting a bottle degreaser inside a dishwasher drawer? “That’s difficult, but it is common for someone to prewash a filthy pot with dish soap in the sink and forget to rinse it before putting it in the machine,” says Josep Freixa. In that case, a lot of foam is generated, making the washing process difficult.

If we realize the error and open the door in the middle of washing to correct it, we do not harm the appliance, although it is not recommended to open and close continuously. Temperature is lost, and we have a higher cost in that washing cycle. “In principle, the worst thing that can happen if you open carelessly when it is working is that you get wet or burn yourself with the water that will come out.”

It is not advisable to wash the lids of pressure cookers so that the rubber bands do not lose effectiveness, nor delicate porcelain objects that can fracture or unglazed ironware.

9. Introduce a kitchen mold that must be washed cold or delicate porcelain

The dishwasher can wash all kinds of materials, although we must pay attention to the manufacturer’s advice with certain types of utensils. For example, a mold to make cakes indicates that it must be washed in the cold or with lukewarm water. The water temperature in the dishwasher is high. “In industrial factories, the regulations indicate that washing must be at 65 degrees and rinsing at 85”, explains Freixa. 

We must also pay attention to the tableware with drawings or engravings so that they do not disappear due to the effect of the heat of the water. we can select the temperature of the dishwasher to avoid it.”

It is also not advisable to wash the lids of pressure cookers so that the rubber bands do not lose effectiveness, nor are delicate porcelain objects that can fracture or unglazed ironware. “What we should never put in a dishwasher is a kitchen cloth because it can clog it,” says Freixa. Or a glass jar with a paper label that can come off and clog the filter.

10. Do not check the filters; use abrasive products

To clean the dishwasher, “it is best to follow the manufacturer’s instructions,” explains our expert, who considers it an urban legend that a monthly wash must be done with the appliance empty to keep it in good condition. 

“It is unnecessary because when we wash the dishes, the machine already washes,” he points out and adds that it is not necessary to wash it with a glass of vinegar, as they say, “it is a disinfectant that does not harm, but it is not required either.

We must check that the filters and diffusers are clean, removing any residue that may end up there: transparent films, pieces of food, a toothpick. Cristina Cusí recommends cleaning them with soap and water.

Metal scouring pads are strictly prohibited because they scratch and scratch stainless steel and can rust the dishwasher and cause a severe breakdown.

We can also clean the inside of the tank with a cloth but never use abrasive products such as bleach or ammonia, “which could damage the appliance and can even perforate it,” says Freixa. Metal scouring pads are strictly prohibited because they scratch and scratch stainless steel and can rust the dishwasher and cause a severe breakdown.

One last piece of advice: if you are going to stop the machine for a while due to a trip or vacation, it is preferable to leave the door slightly open so that it can breathe.
