Benefits of Dishwashers with Food Waste Disposers
As their name suggests, dishwasher-garbage disposal combos provide a significant number of benefits when it comes to keeping your kitchen dishes in crystal clear form.
Consider some of the following if you are still on the fence about adding one of these appliances to your kitchen:
Minimizes residue Spreading
Leaving food waste and debris on one's dishes before putting them in the dishwasher tends to lead to one conclusion: an unpleasant spread of the debris as a residue during the wash cycle.
Oily and gritty foods especially tend to hang around even in the highest powered dishwashers, so minimizing the amount of debris within the wash tub can improve the appliance's overall performance.
Decreases Pipe Clogging
Dishwasher pipes and nozzles are exceptionally prone to clogging from remaining food scraps.
Built-in garbage disposal help minimize this risk to a significant degree, reducing the amount of maintenance and repairs you'll need to do down the road.

Dishwashers with Food Disposal Options
There are two primary types of dishwashers with food disposal capabilities. Be sure to carefully read your product’s listing to know which kind you are considering for your kitchen.
Dishwashers with Built-in Food Disposals
Common in most American-made dishwashers, these models feature a devoted garbage disposal unit within their architecture. These built-in food disposals only carry a fraction of the power seen in under-sink garbage disposals, however.
While this addition is a convenience, it's also not nearly as effective as a standalone garbage disposal.
Dishwashers with Filtration System
Common in European-made dishwashers, these models use a specialized filtration system to catch (but not chop up) food debris. This has the immediate benefit of making these dishwashers much quieter during operation.
However, they must also be cleaned regularly to prevent detritus build up that would otherwise inhibit proper operation.
5 Best Dishwashers with Garbage Disposals Reviewed
1. GE Top Control
Best Multi-Rack Dishwasher
24 x 35”
Number of Cycles
Yes, Limited 1-year for the entire appliance
Though this model features a great assortment of industry standard specifications – from its certified “quiet” performance to its top-mounted control panel – the GE Top Control Dishwasher’s best feature by far is its unique implementation of multiple washing racks.
While the upper two stem racks are ideal for even irregularly tall glasses, the unique third rack corrals and protects flatware and other utensils through the robust washing processes, with four wash cycles, this model doesn't slack off on cleaning performance, either.
This model's internal garbage disposal is relatively strong as well and worth the investment alone.
Despite this appliance's overall high cost, the 3,600 RPM blades inside the built-in garbage disposal make this price well worth it when you no longer need to spend extra time pre-treating your dishes.
In all, the GE Top Control Dishwasher’s multiple wash zones make it an unbeatable choice when it comes to getting the most out of each wash cycle. Metal, glass, and porcelain dishes always come out of this appliance looking as good as new.

Also, this model features adjustable water pressure gauges that allow you to maximize how efficiently its already-low water load is used. This increased water pressure has the bonus of decreasing the likelihood of clogs over the life span of this appliance.

That's not to say this model isn't an effective cleaner, though. This model packs in 6 wash cycles, allowing for maximum sanitation every time.
This model also features a unique wooden exterior that will seamlessly blend in with any wood cabinet-accented kitchen.
The control panel is sleek and hidden, though still readily accessible near the top. Altogether, this model is great for those who are looking for a little more power and a little less sound out of their dishwasher.
5. Samsung 24 in Top Control StormWash

24 x 34”

After finishing its cycles, this model’s AutoRelease door cracks open slightly to allow air to circulate and dry dishes without wasting electricity.
Between these critical features and others on board, this model is another excellent dishwasher option that will keep your cleaning work time to a minimum.
How Dishwashers with Waste Disposals Work Together
Dishwashers with built-in waste disposal systems work together perfectly when integrated into a single device. Like experienced dancers, both components play off each other's strengths and weaknesses to maximize their final output.
For example, dishwashers are unable to be effective if they are full of food scraps. Garbage disposals handle these leftover food bits, allowing the dishwasher to clean each dish without leaving behind residue.
Dishwashers alone cannot clean a kitchen, though. You always need a method for disposing of waste products, but sometimes trashing such debris is not enough to prevent unpleasant smells from wafting through your cooking space.
Garbage disposals handle this end of the equation by effectively and efficiently chewing up smelly leftovers like rotten fruit and minor fragments of egg shells.
Before you buy one of these fruitful combos, however, be sure to thoroughly review the various options available to you – including models with outright built-in food disposals and models with simplified filtration systems.
Connecting a Dishwasher to a Garbage Disposal
Though you may immediately think that this is a job for an expert alone, you can connect a dishwasher to a garbage disposal with much ease. Follow these steps in order get a general idea of how these devices can be installed together.
- 1Evaluate the Task
Though it is possible to complete this task on your own, that doesn't always mean that it is wise to do so. Evaluate the steps shown in your installation guide, and if they feel overwhelming, consider saving yourself some time and effort by contacting a plumber.
- 2Cut Electricity
Before messing with any of the following components, cut power to the garbage disposal and dishwasher. This may be as simple as unplugging both or cutting the breaker to the kitchen.
- 3Prepare the Airgap Fitting
Remove the plug inside the main drain pipe and insert the threaded stem until it is securely in place.
Rotate the hose until it is appropriately orientated to drain into the garbage disposal
- 5Clamp and Cut
Clamp the hose into place and cut any excess tubbing that hangs down between the two fixtures.
- 6Apply Remaining Secure Bits
Secure any remaining points on either device to prevent leaks and depressurization. Make sure all nozzles are correctly oriented to allow for the proper flow of water.
- 7Turn on and Test
Once you’ve completed all steps, you can turn back on the electricity and test each component.

Be sure to consult your owner's manual to get a more specific understanding of how to connect your garbage disposal and dishwasher. Specialized connector kits are also available, should you need an extra.
Fixing Clogged Drains Due to Dishwasher
Fixing a clogged dishwasher drain can be easy if you know what to look for. If you have standing water left in your dishwasher or it's backing up into your sink, this may be the cause.
Inside most dishwasher models, a small upside-down cup-like object can be seen in the central body interior.
This cup floats and signals when the appliance should drain water. At times, this device can become lodged open or shut, causing the dishwasher to perform improperly. This could cause an FE error code, on a Samsung Dishwasher.
To remove these jams, reach in and remove whatever is causing the device to be wedged in place.
Then, run the dishwasher to see if it clears the jam. If water drainage problems persist, you may need to check the interior further and scrub off excess build-up that has formed over the drainage ports.
Installing a Built-in garbage disposal Dishwasher
Installing a dishwasher with built-in garbage disposal doesn't need to take extra time if you plan correctly.
Though this job is best left to a plumber, you can also try to install these fixtures by yourself following these general steps:
- 1Prepare the Space
Measure the location where you intend to install the appliance and ensure that it has enough space for the full fixture as well as associated piping (varies based on kitchen orientation).
- 2Connect the Water Line
Using a dual outlet valve, connect the dishwasher into the main water line. Orient, the other input and output lines, to allow hot and cold water to flow through the appliance properly. These ports will likely be marked on the back of the device and should be secured with Teflon tape.
- 3Connect the Drainline
Connect both ends of the drain line to the appliance and sink drain pipe appropriately, ensuring that it is done at an upward angle to prevent backflow.
- 4Wire the Device
With the power shut off to the kitchen, wire the device in accordance with the guides in your manual. These can vary dramatically between different brands, so be sure to check specific wiring orientations before engaging in this practice. You should expect to see a white, green, and black wire, which are the neutral, ground, and hot wires respectively.
- 5Secure the Dishwasher
Slide the full appliance in, assuring that no cords or pipes are pinched off in the process. If the machine requires mounting, use the appropriate mounting brackets to ensure maximum stability.
Like with any appliance, you should always consult your specific installation manual for precise instructions regarding the installation of your particular fixture.

Dishwasher With Garabage disposal FAQs
How far can a dishwasher be from the sink?
In theory, there is no limit to the distance between these two fixtures. In the end, the total length allowable comes down to how much extra piping and tubing you want to use to connect the dishwasher back to the main water lines.
What causes standing water in dishwashers?
Standing water after use can be caused by several sources. The first and most apparent is the improper use of dish detergent. Low-quality powdered detergents, in particular, can clump up and cause the appropriate drainage pipes to become clogged.
Also, improperly loading (or overloading) your dishwasher may cause water to improperly collect in usual parts of the tub after the wash cycle.
What is a hard food disposer on a dishwasher?
A hard food disposer in a dishwasher is comparable to a traditional under-sink garbage disposal, though with substantially less power and a high reliance on continuous water flow to operate.
What is a food grinder inside the dishwasher?
Along the same lines, food grinders inside dishwashers serve the taste of chopping up food debris, making it easier to push down the drain – similar to a traditional garbage disposal.
How loud should I expect a dishwasher to be?
Modern standalone dishwashers can be pretty quiet, especially if they are water efficient and maintained properly.
However, models with a bonified garbage disposal built intend to make some extra noise caused by the main grinding process. Filtration-style dishwashers don't make this much noise, comparatively.
Why do we recommend buying these products through Home Depot?
Though your local appliance shop is always a great option, Home Depot is a readily accessible online store with knowledgeable staff who can provide you personalized assistance when it comes to picking out a garbage disposal or dishwasher.
Their website catalog also provides excellent details on leading models, making for easy comparison shopping.
Altogether, there is a lot to know about dishwashers, both with and without built-in garbage disposals.
While it’s hard to pick just one out of this outstanding field of high-performing models, I would gladly add the GE Top Control Dishwasher to my kitchen next time I remodel.
This dishwasher has an outstanding amount of rack space, perfect for my large family, as well as a highly effective garbage disposal to prevent it from clogging up in the short-term.
