Water only under the crisper drawers
The shelves above are dry, but the bottom of the fresh-food section keeps collecting water.
Start here: Start with the defrost drain and rear interior drain trough.
Fresh-food section leak
Samsung Refrigerator Water Under Crisper Drawer
Direct answer: If water keeps showing up under the crisper drawers, the most common cause is a defrost drain that is iced over or clogged, so melt the ice, clear the drain path, and make sure water can run to the drain pan below.
Most likely: Most of the time this is meltwater from the evaporator getting trapped inside the refrigerator and running forward into the crisper area instead of down the drain tube.
Start by figuring out whether the water is clean defrost water inside the cabinet or a supply leak from the filter or dispenser line. That split matters. A little puddle under the drawers can come from two very different places, and the easy fix is usually the right one. Reality check: one towel-up does not mean it is fixed. Common wrong move: chipping ice out with a knife and puncturing a liner or drain tube.
Don’t start with: Do not start by ordering a control board or tearing into the sealed cooling system. This problem is usually a blockage, ice dam, or a simple drain-related part issue.
If the water is only inside under the drawersCheck the defrost drain path first.
If you also see drips near the filter area or floorLook for a water supply leak before opening panels.

What this leak usually looks like
Ice under the drawers that later turns to water
You find a thin ice slab or frozen ridge at the bottom, then a puddle after the door has been opened a while.
Start here: Start with a frozen defrost drain or weak drain heat transfer strap.
Water inside and a little on the floor
Water begins under the drawers, then spills out when the drawer area fills up.
Start here: Still check the internal drain first, then confirm the drain pan is not overflowing from a blocked tube.
Water near the filter housing or dispenser side
You see drips from a corner, wall, or ceiling area inside the fresh-food section, or dampness near the filter compartment.
Start here: Check the refrigerator water filter seating and water line connections before chasing the defrost drain.
Most likely causes
1. Frozen or clogged refrigerator defrost drain
This is the classic cause when water collects under the crispers while cooling still seems normal. Defrost water cannot get down the tube, so it runs into the cabinet instead.
Quick check: Remove the drawers and look for ice or standing water at the rear floor of the fresh-food section.
2. Loose debris or sludge in the refrigerator drain tube
Even if the ice is gone, food bits and slime can slow the drain enough that water backs up during each defrost cycle.
Quick check: After melting visible ice, pour a small amount of warm water into the drain area and see whether it disappears quickly.
3. Weak or missing refrigerator drain heat transfer strap
Some units rely on a small metal strap or clip to help keep the drain opening from freezing shut again. If it is out of place, the leak often returns after you clear it.
Quick check: If you clear the drain and the puddle comes back within days, suspect the drain opening is refreezing.
4. Refrigerator water filter or water line leak
If the water is coming from one side wall, filter area, or ceiling area rather than the rear floor, this is a different problem than a defrost drain backup.
Quick check: Dry everything, then watch for fresh drips while dispensing water or right after the ice maker fills.
Step-by-step fix
Step 1: Pin down where the water is starting
You want to separate a defrost drain problem from a pressurized water leak before you pull panels or buy parts.
- Empty the crisper drawers and dry the whole bottom of the fresh-food section with towels.
- Check the rear floor of the compartment for ice, slush, or a wet trail coming forward from the back wall.
- Look up at the filter housing area, side walls, and ceiling of the fresh-food section for fresh drips.
- If your refrigerator has a dispenser or ice maker, look behind and under the unit for water on the floor that lines up with the supply side.
Next move: If the water clearly starts at the rear bottom inside the cabinet, move to the drain-clearing steps. If you cannot tell where it starts, keep the area dry for a few hours and recheck after normal door use or after dispensing water.
What to conclude: Rear-bottom pooling usually means defrost water is trapped. Side, ceiling, or filter-area drips point more toward the refrigerator water filter or water line.
Stop if:
- You find active dripping from a water line connection behind the refrigerator.
- Water is reaching an outlet, power cord, or flooring that can be damaged quickly.
- You have to force trim, shelves, or panels that are not coming free easily.
Step 2: Clear the easy ice and drain blockage first
A frozen drain opening is the most common reason water ends up under the drawers, and it is often fixable without parts.
- Unplug the refrigerator or switch off power before working inside the drain area.
- Remove drawers and any lower shelf pieces needed to reach the rear floor and drain trough.
- Use towels and warm water to melt visible ice. A turkey baster or squeeze bottle works well for directing warm water into the drain opening.
- Keep flushing with small amounts of warm water until it begins to move down instead of pooling back up.
- Wipe the area dry when finished.
Next move: If warm water starts draining freely and the puddle does not return over the next day or two, the blockage was the main problem. If water will not go down at all or immediately backs up, the drain tube below is still blocked or frozen farther down.
What to conclude: A simple ice dam or light debris blockage is common. A stubborn backup means the drain path needs more attention from the rear or lower access area.
Step 3: Check the drain tube path and drain pan below
If the top opening is clear but water still backs up, the restriction is often lower in the refrigerator drain tube or at the outlet above the drain pan.
- Pull the refrigerator out carefully and protect the floor if needed.
- Remove the lower rear access cover if your unit has one.
- Find the drain tube outlet above the drain pan and look for sludge, a stuck duckbill-style outlet, or ice at the end of the tube.
- Clean the outlet and flush the tube with warm water from above or below until it runs clean into the drain pan.
- Make sure the drain pan is seated properly and not already overflowing from debris or poor airflow around it.
Next move: If water now runs cleanly into the drain pan, reassemble and monitor for the next few defrost cycles. If the tube stays blocked, kinked, split, or inaccessible without major disassembly, it is time for a closer teardown or service call.
Step 4: If the leak keeps coming back, look for refreezing at the drain opening
When the puddle returns soon after a good cleaning, the drain opening is often freezing shut again rather than clogging with new debris that fast.
- Recheck the rear interior drain area after a day or two of normal operation.
- Look for a fresh ice plug forming right at the drain opening or a thin ice sheet spreading across the bottom again.
- If you can see a small metal heat transfer strap or clip near the drain area, make sure it is present and positioned to conduct warmth toward the drain opening.
- If the back wall inside the refrigerator or freezer is heavily frosted, note that you may have a larger defrost issue rather than just a drain issue.
Next move: If repositioning the strap or clearing a small new ice plug stops the repeat leak, you likely caught the real cause. If the drain keeps freezing or you also have heavy frost on the back wall, the problem may involve the refrigerator defrost heater area or a broader defrost failure.
Step 5: Rule out the water filter and supply side before you close up
A supply leak can mimic a drain problem, especially when water tracks along liners and lands under the drawers.
- With the inside dry, reinstall the refrigerator water filter if equipped and make sure it is fully seated and locked.
- Dispense water several times and watch the filter area, nearby ceiling, and rear corners inside the fresh-food section for fresh drips.
- Check the household water line connection behind the refrigerator for moisture after dispensing and after the ice maker cycles.
- If you confirm the leak is tied to dispensing or ice production, shut off the refrigerator water supply until the leaking connection or filter issue is corrected.
A good result: If no new drips appear during water use and the drain is flowing, put the refrigerator back in service and keep an eye on the crisper area for two days.
If not: If water appears only when the dispenser or ice maker runs, focus on the refrigerator water filter seating or water line leak instead of the defrost drain.
What to conclude: A leak that follows water use is not normal defrost runoff. It is a pressurized water path problem and should be treated that way.

FAQ
Why does water keep collecting under the crisper drawers but nowhere else?
That usually means defrost water is not making it down the refrigerator drain. It pools at the rear bottom, then runs forward under the drawers because that is the lowest open area inside the fresh-food section.
Is this usually a clogged drain or a bad water filter?
Most often it is the drain. Suspect the refrigerator water filter instead when the leak starts near the filter housing, side wall, or ceiling area, or when it shows up right after dispensing water or making ice.
Can I pour hot water down the refrigerator drain?
Use warm water, not boiling water. Warm water is usually enough to melt the ice and flush light debris without stressing plastic parts or liners.
Why does the leak come back a few days after I clear it?
That usually means the drain opening is freezing shut again or the lower drain outlet is still partly restricted. A missing or poorly positioned refrigerator drain heat transfer strap can also cause repeat freeze-ups.
Do I need a service call if the refrigerator is still cooling fine?
Not always. If the problem is just a blocked drain and you can clear it safely, this is often a manageable DIY repair. Call for service if the drain keeps refreezing, the back wall is heavily frosted, cooling is getting worse, or you confirm a water line leak you cannot access safely.
