1 – Do you hear abnormal sounds?

If you hear any abnormal shaking, thumping, or gurgling sounds, it’s a major turn-off! Make sure you listen to it while you’re running your dishwasher. It sounds like the water is trying to unleash via a clog in your primary or secondary sewerage system.

It indicates a partial or significant clog in your kitchen sewerage system whenever you observe water pooling in the bottom of your sink or dishwasher. You must clear this clog ASAP so the future won’t come with more severe issues.

3 – Is your dishwasher stinking?

A foul odor is another crucial sign not to be ignored! When you observe that you’ve already cleaned your filter basket and something is still feeling stinky out of the dishwasher, there’s a clog to blame. And it also says that you’ve not done cleaning well!

So, go, and clean it properly. Particles and clogs will build up without regular cleaning too. So, ensure you have a disciplined routine of decluttering or kitchen organization once every 4-5 times a month.

4 – Check if any type of food choke up your drain line

It means your dishwasher isn’t draining correctly if there’s standing water even after the wash cycle. This is because some leftover food particles are clogging the system.

So, you need to inspect the concern and clean the drain basket thoroughly. There’s a significant clog within the drain line if cleaning the drain basket also didn’t solve your problem.

5 – Do you add dirty dishes?

Is your dishwasher fulfilling its primary purpose? Are your dishes coming out being cleaned? If they are coming out dirty, and before you’re suffering from a clog in its drain hose, here’s a sign that you’re suffering from a clog.

6 – Installing a new garbage disposal

If the garbage disposal installation isn’t done right, it may cause a clog of the entire system. So, you need to get your installations done with technical expertise, not to get such kinds of return gifts.

The clog may generally happen when the knockout plugs aren’t removed during installation. So pull that plug now and eliminate your clogging issue if this is the case. Also, think of replacing your old garbage disposal with the new one,e as the older one has more clogging issues to keep you busy often!

How to Unclog a Dishwasher: The Best Way

1 – Run your garbage disposer

Turn on your kitchen sink tap, and flip its garbage disposal. The purpose here is to let the water pass thoroughly through this disposal. Since the dishwasher’s garbage disposal and kitchen sink share the identical drain line, this running water would help clear out the clogged path.

2 – Run a complete dishwashing cycle

If the problem persists, turn on the power, and rerun the complete dishwashing cycle. Also, check if you’ve used the suitable detergent and loaded the dishwasher correctly.

Open the door once the cycle stops, and check if any water is still standing at the bottom of the dishwasher. You need to call the expert technician if you see an abnormal amount of water standing.

You can use a DIY mixture of equal vinegar and baking soda. Mix them with water, and pour them into the dishwasher drain basket at the bottom. Let it sit there for 15 minutes, and wait for the cleaning magic to happen!

Pour hot water from the top after those 15 minutes of a miracle. It will probably flush out all the unclog and baking soda solution. And it’s one of the most effective ways to unclog a dishwasher!

4 – Check dishwasher filter

If your dishwasher is clogged then clean your dishwasher filter.

You also need to check the filter, which is located at the bottom of the dishwasher tub near the spray arm. You can change the filter if it’s too old and doesn’t work correctly, even after regular cleaning.

Many homemakers don’t even realize that the filter needs to be changed after a specific period. The filters of high-quality dishwashers can last up to 5 years but not more. And they are generally located at the bottom of the dishwasher if you’re facing any difficulty finding them!

2 – Malfunctioned in the pump

If you observe that the water is still standing at the bottom of the dishwasher even after all the wash cycles, there could be a high chance of pump malfunction.

Some specific dishwashers require a particular type of detergent powder, while others don’t. Always use a suitable detergent powder for your dishwasher.

4 – Clogged air gaps
