A Samsung dishwasher not draining can be frustrating. You try to wash your dishes and you find that the water is still filling up in the bottom of the machine.
If this problem persists, it may be time for a Samsung repairman or Samsung dishwasher parts replacement. Before you do that, though, read our tips below to see if there are any quick fixes that will help get things flowing again.
Nobody likes to do dishes. But if you’re the one stuck with them, it’s important to make sure your dishwasher is draining properly. That way, you won’t be left scrubbing dried-on food off of plates and eating utensils that have been sitting in a dirty water reservoir for days on end. It can lead to more than just bad smells and icky messes – over time, it could even cause an expensive flood or leak.
Make sure your Samsung dishwasher is working properly by following these simple steps.
What Causes Samsung Dishwasher Not Draining? Troubleshooting and Diagnosis
If you are experiencing a problem with your Samsung dishwasher not draining, there may be an easy fix! Follow this guide to diagnose the issue and get back on track.
Check Drain Hose
One of the most common Samsung dishwasher not draining problems is a clogged drain hose. This can happen for any number of reasons, from food particles to plant material and even tree roots that have grown into your line over time.
One way you can tell if it’s just debris is by turning off the water supply valve at your wall (it should be labeled). If there are no leaks anywhere when you do this, then it’s likely just buildup in your Samsung dishwasher drainage system.
To clear out these blockages, we recommend running hot water down the length of the pipe with good force, which will help break up residue, so it passes through more easily; or try spraying some CLR cleaner on them before giving it another shot.
Another reason for the Samsung dishwasher won’t drain due to the kinked drain hose. This could be from items being pushed down into it, or simply from wear and tear over time, or due to incorrect installation.
To fix this Samsung dishwasher problem, take off your Samsung‘s upper rack (it should just pop right out), then remove the screws that hold on the front panel to get access to your plumbing connections. Then gently push up on the line at different points until you feel resistance – once you find where there are no more bends in it, tighten that point with plumbers tape, so it doesn’t happen again.
Clogged Drain Filter
Samsung dishwasher won’t drain because of a clogged filter. A Samsung dishwasher can accumulate a lot of food particles and grease, which will eventually build up in the strainer under your sink that serves as your Samsungs’ water supply.
If this happens to you, then don’t worry – it is an easy fix! Just unscrew the old one (some might be secured with plumbers tape), take out all the gunk inside by hand or using a long-handled scrubber brush, rinse thoroughly before putting back together again. You’ll have a clear flowing Samsung dishwashing machine in no time.
Clogged Garbage Disposal
One other issue to check out if you are looking for why my dishwasher isn’t draining is the disposal. A hose in the drain line will lead from your appliance and go into the garbage disposal.
It’s a way of disposing of any excess water that may not make it all the way through. The clogged disposal can delay water movement out of the dishwasher, creating a major standing water effect in your dishwasher.
To avoid a clogged drain, make sure the garbage disposal has been emptied of food particles and is running on low for a few seconds. If this doesn’t work, you should clean your drains.
Check Drain Pump
A faulty pump is rare in Samsung dishwashers, but it can happen. Drain pumps utilize an impeller to drain out the water of your dishwasher, and sometimes they become damaged by a number of things like broken glass or foreign objects that clog the system.
When you start up this cycle on any given day, there might be humming noise coming from the motor, which indicates something inside is wrong with the pump itself – usually, pieces of shattered glass are found at fault for these problems.
Check the impeller if any foreign objects have clogged it. You can easily clean it by scraping off the debris. Rotate the impeller with your finger to see if it’s operating properly.
Ensure that the motor is not running in the wrong direction. Samsung dishwashers are designed so that the motor should run in one direction only, and if it is running backward, you will need to replace the motor.
Clean the Air Gap
Check the air gap cylinder to make sure it’s not clogged with debris. This piece balances water flow, preventing backup during washing cycles and keeping your dishwasher running smoothly.
It is normally located behind your sink near the washer outlet hose; if you notice any buildup from food or foreign objects, clean it out immediately so that proper drainage can continue uninterrupted.
The timer in your dishwasher is there to control the motor and drain solenoid. And if it’s faulty, you may be getting water stuck in your appliance or have a leaky sink! When this happens, we recommend replacing the defective part quickly so that nothing else gets damaged.
Using the Wrong Type of Detergent
One possible cause of the Samsung dishwasher not draining is if you have been using a liquid detergent. Many machines are set up to use powder rather than liquid detergents.
You’ve likely used liquid soap in a pinch if you’re like most of us. While it does a fine job cleaning your dishes, the suds that it creates can prevent dishwater from draining properly after the cycle is completed.
The fix to this problem is fairly simple: refill the detergent compartment with the type of soap specified by your dishwasher manual. If you go for a liquid, take care not to overfill it.
Stuck Check Valve
A check valve prevents water that has traveled out of the dishwasher from coming back so you can continue to wash dishes without interruption.
If the check valve is stuck in the closed position or has been damaged, water will not drain from your dishwasher.
It is possible to clean the valve, but you should replace the check valve if that does not work.
Turn on the faucet and let the water run for a few minutes. Then check to make sure that it drains into the sink.
If your Samsung dishwasher is not draining, it could be the result of a few different things. Improper installation can cause a buildup in the drainage pipes or drain pump that will clog and stop water from flowing out properly.
The most common reason for this error code is an obstruction of some kind – either debris on the filter screen inside the dishwasher or something blocking one of the holes in the sink’s strainer basket.
To minimize these issues, we recommend you clean your filters regularly to keep them free from grease buildup and use a hose to flush out any obstructions preventing water flow when possible.
