S To Unclog Dishwasher Drain

How come my dishwasher is backing up in my sink?

Most households have a dishwasher, as with active families, it is hard to keep up with hand washing dishes in the sink. Often, it is easier to throw the dishes into the dishwasher so it can run and clean everything for us. However, the dishwasher drain needs to be cleaned out and if not, it might stop working.

If it does this, you may be wondering how to unclog dishwasher drain? There are a few ways to do this: Locate and remove the dishwasher filters, clean the filters and the drain, check the plumbing connections, turn on the garbage disposal, check the air gap on the sink, and clear the drain.

Lets take a look at the dishwasher drain, the life expectancy of the dishwasher, and the steps to unclog the drain.

You Have A Clogged Vent Pipe

Your plumbing system requires effective venting to work properly. This venting enables the system to take in the air that it needs to keep water flowing smoothly. If your vent pipes are clogged, water may struggle to flow through the system. It isnt uncommon for bugs, squirrels, or birds to build nests inside these vents, blocking the pipe.

If this is the case, you will need to check the roof for any blockages in the vent pipes. Ask a professional to remove any debris from the vent pipe, which may have potentially caused the water to back up in your kitchen sink.

Install An Air Gap Or Add A High Loop

When you connect a dishwasher drain line to a garbage disposal, the connection slopes towards the dishwasher. This means that the water from the garbage disposal will easily flow into the dishwasher. But that is now how it should work. You can prevent this backflow by using a small device called air gap.

A dishwasher air gap is a small cylindrical device sitting on your sink. It usually sits near the faucet. An air gap prevents water in the sink from draining in the dishwasher. It has two hose fittings under it. When you have a garbage disposal and a dishwasher, the dishwasher outlet hose connects to one fitting of the air gap, and another hose from the garbage disposal connects to the air gaps other fitting.

The air gap prevents the backflow of water from the garbage disposal into the dishwasher since it sits higher than the dishwasher connection. Since water doesnt drain against gravity, the air gaps higher position prevents water in the garbage disposal from draining into the dishwasher. The air gap also lets fresh air into the drain hoses, eliminating any suction forces that can back up water into the dishwasher.

Shown above is a video detailing the installation of an air gap. You can do it by yourself if you have the necessary tools. The most difficult part of the installation is drilling the countertop the rest is easy.

Dishwasher Water Supply Line Hot Or Cold

How to Fix a Dishwasher Backing Up into Sink

It depends on the manufacturer and the model of the dishwasher but most dishwashers, especially in the US are designed to be connected to a hot water supply line. This is especially true for under-counter built-in dishwashers.

Never be tempted to connect your dishwasher to a cold water source as this will not produce the result you desire. The hot water cuts through grease and removes stuck foods on the dishes more efficiently. It also helps to sanitize the dishes.

We know that most dishwashers come with internal heating elements that heat the water that comes into the dishwashers before washing the dishes, but this doesnt mean you should connect your dishwasher to the cold water supply line.

The heating element in your dishwasher is supposed to heat the incoming hot water until it gets to the temperature the dishwasher requires to wash your dishes efficiently.

If it is cold water that comes into your dishwasher, the heating element will work longer and harder to get this done which will weary it faster. It will also take time.

Old dishwashers dont even have heating elements, so nothing heats the water once it gets into them. You cant avoid connecting them to hot water supply lines unless you want to deal with dishes that arent well cleaned.

Before connecting your dishwasher to a hot water supply line, however, ensure the manual doesnt say different.

On its size, the most recommendable diameter is ¾ inches. However, you should highly consider the pipe you are connecting with.

Additionally, you should also check the length of the waste pipe. Ideally, it should be long enough to reach the septic tank or the drainage area.

Check The Air Gap Cylinder

Some homes will have an air gap cylinder and it is what keeps the water flowing in the correct direction during the dishwasher cycle. It also prevents wastewater from backing up into the dishwasher during its cycle. If you have one in your home, check this cylinder for any clogs or debris as well. If it is not clear, then you will need to clean it out and re-install it securely.

The air gap cylinder is located behind the sink and near the dishwasher outlet hose. If your home doesnt have one, then sometimes they are built into the dishwasher. If you are buying a dishwasher, check the rules for your state if an air gap is required or not. It will vary state by state.

    How To Unclog A Dishwasher

    Dishwasher photo and guides: Dishwasher Blocked Kitchen Drain

    Sometimes, the reason why your sink is backing up water is due to a clog inside the dishwasher. After all, blockages in the dishwasher can mess up the drainage process. Unclogging a dishwasher can be a complicated task and you must follow the proper procedures to avoid compromising or damaging the kitchen appliance.

    Heres a breakdown of all the steps to unclog your dishwasher the right way.

    Step 1: Unplug the dishwasher from the wall outlet

    As is the case with any electrical appliance, you need to unplug your dishwasher from the power source to avoid accidents.

    Step 2: Detach the kickplate

    See the piece of metal just below the dishwasher? To pull out the kickplate, remove its fasteners first with a screwdriver. Place the plate and the screws to one side for retrieval later.

    Step 3: Inspect the drain hose

    You get instant access to the drain hose once the kickplate has been removed. The drain hose is the hose connecting the dishwasher pump to the drain. Before pulling it out, set a wide pan below the part where the hose and the dishwasher meet to catch any spillage. Make sure you have a dry rag at the ready in case some of the water falls on the floor.

    Step 4: Remove the drain hose

    Most dishwashers have a wire clamp attaching the hose to the pump. Loosen the wire clamp with your pliers and then gently pull the hose out.

    Step 5: Loosen the clogs

    Step 6: Flush out the loosened clogs with a garden hose

    Step 7: Unclog the recirculation hose

    Step 9: Plug the hoses back on

If you ever need to replace the filter, you will look in the handbook for the make and model of the dishwasher to make sure you purchase the right replacement.

The dishwasher is typically placed so that it can be seen from the front of the sink, which means that if it isnt in use, you can put away your dishes by simply turning on the faucet and walking away.

    This isnt always the case for everyone, though some people have an arrangement in their kitchen where their dishwasher is located behind a cabinet and not next to the sink. If this is the case for you, make sure to check with your installer or landlord to see if they are able to retrofit your dishwasher with a built-in water sprayer so that all of your dishes can be sprayed at once.
