Pull the drawer out, take the inserts apart, wash everything under running water, brush out the recess it slides into, then refit the siphon cap firmly. The recess is the half most guides skip, and the siphon cap is the part that decides whether the drawer dispenses at all.
Samsung is blunt about why it matters: “Using too much detergent can gunk up the detergent drawer, causing less to reach your clothes. It can even contribute to odors and other issues with your washer” (how to clean your Samsung washer).
Odors are only half of it. Leakage. A blocked drawer is a genuine cause of water on the floor — Samsung keeps a separate troubleshooting path for a detergent drawer that is leaking (dispenser drawer issues) — and almost nobody connects the two.
What actually gets dirty, and where
There are two separate things here, and most guides on how to clean washing machine detergent drawer residue deal with only the first. That is why it comes back.
How to clean washing machine detergent drawer parts, step by step
Five steps, ten minutes, no special product required.
- Unplug the machine. It is not strictly required to pull a drawer, but you will be reaching into a recess with a brush, and it costs nothing.
- Release the drawer and lift it out. Samsung’s method is the standard one: “Press and hold the button on the inside of the dispenser while pulling out and lifting up on the drawer.” The button is usually in the softener compartment. Do not force it — if it will not come, you have not found the catch.
- Take it apart. Remove the liquid detergent insert and its siphon cap, and lift out the softener and bleach compartments if yours has them. These are separate parts and they hide the worst of the residue underneath.
- Wash everything under running warm water. A soft brush or an old toothbrush does the corners. All of it can go in a dishwasher on the top rack — but Samsung adds a warning worth heeding: “Do not dry in the dishwasher, as the heating process can damage the plastic.” Wash cycle yes, heated dry no.
- Brush out the recess. Samsung’s own instruction is to “clean the dispenser recesses with a soft brush.” Reach up and feel the roof of it: that is where softener sets into a grey crust, and where the flush jets clog.
Then refit, and this is the step that matters most: re-insert the siphon cap and push it firmly into place. A cap left loose or upside down stops the compartment siphoning, and the machine will look like it has a dispensing fault.
Finish it the way the manufacturer does
Samsung’s procedure does not stop at reassembly. It ends with a cup of chlorine bleach in the liquid bleach dispenser and a rinse-and-spin cycle with no load in the washer, which flushes the passages the brush could not reach.
Run that on its own. No detergent, no softener, no vinegar in the same cycle. Mixing cleaning chemicals in a closed drum can produce harmful fumes, and there is nothing to gain from combining them.
If your machine has no bleach compartment, run the hottest empty cycle it offers instead. The point is a flush, not the chemistry.
Why it clogged in the first place
Cleaning it is easy. Keeping it clean means fixing whichever of these applies, and the last one surprises everybody.
- Too much product. Samsung’s line is “Do not exceed the MAX line, and use as little as possible to get the job done.” Anything above the line does not dispense; it sits there.
- Liquid without the insert. Without it, “the additive will drain into the tub immediately. This will cause stained clothes, residue buildup, dispensing issues, and odors” (dispenser drawer issues).
- Cold washes with powder. The jets deliver cold water, the powder does not fully dissolve, and what is left cements itself in the corners.
- Softener, always. It is the stickiest thing that goes in there and it dries to a paste. If a compartment is caked, it is nearly always this one — where to put fabric softener covers which one it should be going in.
- The machine is not level. This is the one nobody expects. Samsung documents it directly: “If the washer is not level, it will cause an incorrect slant in the detergent drawer, affecting how the siphons work.”
That last point is worth acting on. If your drawer keeps flooding or keeps leaving product behind after a proper clean, check the machine is level before you buy anything.
How often, and what happens if you leave it
How often to clean washing machine detergent drawer parts has a simple answer: monthly, and it belongs in the same routine as the drum and the filter — the full schedule is in how often to clean a washing machine.
Left alone, the sequence is predictable: residue narrows the passages, the siphon stops clearing properly, product is left sitting in the drawer after a cycle, and eventually water backs up over the front. At that point people usually go looking for a leak in the door seal, when what they have is a drawer that cannot empty. If detergent is being left behind rather than washed in, start with detergent not dispensing.
FAQ
How do I get the detergent drawer out?
Press and hold the release catch, usually inside the softener compartment, then pull out and lift. If it resists, you have not pressed the catch — forcing it breaks the runners.
Can I put the detergent drawer in the dishwasher?
Yes, on the top rack. Do not let it run the heated dry cycle, which can warp the plastic.
What is the small plastic cap in the drawer for?
That is the siphon cap, and it is what makes the compartment empty itself when the water level rises. Without it seated properly, liquid either drains straight through or never leaves at all.
Why does water sit in my detergent drawer after a wash?
A blocked siphon, a clogged recess jet, or a machine that is not level. A small amount of residual water is normal; a full compartment is not.
Can I use bleach to clean the drawer?
Yes, as its own cycle, exactly as the manufacturer describes. Never alongside detergent, softener or vinegar.
How often does a washing machine detergent drawer need cleaning?
Monthly, alongside the tub-clean cycle. Sooner if you use powder in cold washes or a lot of fabric softener.
Is there a detergent that does not use the drawer at all?
Yes. A strip goes straight into the drum with the laundry, so there is no dispenser to coat and nothing to set hard in a siphon — which is the one maintenance job laundry detergent sheets remove outright. They give up other things in exchange, and that page is honest about which.
