Quick answer: If your Samsung top loader won’t drain or spin and water is sitting in the tub, the usual fix is a new genuine Samsung drain pump, $29.95, with same-day dispatch from our Sydney warehouse. It’s a 30 to 45 minute DIY job with basic tools.
Last updated June 2026
A Samsung top loader that fills and washes fine but leaves a tub full of water at the end of the cycle has a drain problem nine times out of ten. On these machines the part that fails most often is the drain pump. The pump is a small motor with an impeller that spins to push wash water out through the drain hose. Over the years the motor windings burn out, the bearings seize, or the impeller jams on a coin, hairpin or sock fibre. Then the water has nowhere to go, the spin cycle won’t start (the machine won’t spin a full tub), and you may see fault behaviour on the display.
Below you’ll find how to diagnose the fault, confirm the pump is the culprit, test the old pump for continuity, clear a jammed impeller, and fit the replacement pump.
How do I know it’s the drain pump?
The signature of a failed drain pump on a Samsung top loader is simple: the machine washes, then stops with water still in the tub and won’t spin. Work through these symptoms. The more that match, the more likely it’s the pump:
- Water left in the tub at the end of the cycle. The wash completes but the tub never empties.
- Won’t advance to spin. Samsung machines won’t spin a full tub, so a drain failure looks like a spin failure too.
- You can hear a hum but no water moving. A humming or buzzing pump that won’t shift water usually means the impeller is jammed or the motor is on its way out.
- Dead silence where the pump should kick in. No hum at all near the drain phase often means an open (burnt-out) pump winding.
- Fault behaviour on the display. Samsung top loaders may flash a drain-related fault and stop. Don’t fixate on the exact characters; different models display different codes for the same “I can’t drain” condition. What the machine does (water in, won’t drain, won’t spin) tells you more than the letters do.
Before you condemn the pump, rule out the cheap, free causes first:
- Kinked or blocked drain hose. Pull the machine out and check the hose isn’t crushed behind it or clogged with lint.
- Standpipe or drain blockage. Make sure the wall standpipe the hose feeds into isn’t blocked.
- Blocked pump inlet or filter. A coin or sock can block the pump inlet so the motor runs but moves nothing.
If the hose and standpipe are clear and the tub still won’t empty, the drain pump is the prime suspect. The test that settles it is a continuity check on the pump motor, covered in the steps below.
Which drain pump fits my Samsung top loader?
The genuine Samsung drain pump for these top loaders is a direct plug-in replacement: same mounting, same electrical connector, same hose spigots, no modification needed. Always cross-check the part number printed on your old pump (and your machine’s model number on the door-frame or rear sticker) against the listing before ordering. The model sticker is usually around the lid hinge or on the back panel.
| Part | Fits these models | Genuine / Compatible | Price | Buy |
|---|---|---|---|---|
 Genuine drain pump | Samsung top-loader washing machines fitted with this drain pump. Confirm against the number on your existing pump and your machine’s model sticker. | Genuine Samsung | $29.95 |
Samsung re-used this drain pump across a wide span of top-loader production, so the most reliable thing you can do is read the number off the old pump and match it against the number in the listing title. If they match, this genuine replacement is the correct part. If your machine carries a different pump part number, use our part finder or browse the full washing machine parts store to match it exactly. Buying the genuine pump takes the guesswork out of it; it’s the same pump Samsung fitted at the factory.
How to replace the Samsung drain pump step by step
Time: 30 to 45 minutes. Difficulty: beginner to intermediate. Cost: $29.95 for the part.
Tools you’ll need:
- Phillips head screwdriver (PH2)
- Flat-blade screwdriver (for the spring hose clamps, or a pair of pliers)
- Pliers or hose-clamp pliers
- 8mm / 10mm nut driver or socket (some mounting screws are hex-head)
- A multimeter for the continuity test (strongly recommended)
- A shallow tray or old towels (there will be trapped water)
- A torch
- Optional: a small bucket to bail the tub if it’s full
Safety first: Switch the machine off at the power point and unplug it before you touch anything. Turn off the water taps at the wall. There’s water trapped in the tub and pump, so have towels ready. Never work on a plugged-in machine.
Step 1, power and water off. Unplug the machine at the wall and turn off both water taps. The pump is mains-powered, so this is not optional.
Step 2, drain the trapped water. If the tub is full, bail as much as you can with a jug, then lower the drain hose into a bucket on the floor to siphon the rest. Getting the water out now saves a flood later.
Step 3, access the pump. On most Samsung top loaders the drain pump sits low at the rear or base of the cabinet. Pull the machine away from the wall, lay it back gently (or tip it onto a towel) and remove the rear service panel or base panel with your screwdriver or nut driver. Keep the screws in a cup so you don’t lose them.
Step 4, photograph the wiring. Before disconnecting anything, take a phone photo of the pump’s electrical connector and the hose positions. This is your reassembly map.
Step 5, disconnect the wiring. Unplug the electrical connector from the pump. It usually has a small locking tab. Press it and pull the plug straight off; don’t yank the wires.
Step 6, release the hoses. Slide the spring clamps back with pliers (or loosen the screw clamps) and ease the drain hose and tub hose off the pump’s spigots. Have your tray ready, because more water will come out here.
Step 7, remove the old pump. Undo the mounting screws or release the locating clips and lift the old pump out.
Step 8, test the old pump for continuity and check the impeller. With the pump out, do two things:
– Continuity test: Set your multimeter to the resistance / continuity (Ω) range and touch the two probes to the pump’s two motor terminals. A healthy pump motor reads a low, finite resistance (typically a few to a few tens of ohms), which is good continuity through the winding. If the meter reads OL, infinite, or no continuity, the winding is open (burnt out) and the pump is dead, which confirms the replacement was the right call.
– Clear the impeller: Look into the pump inlet and spin the impeller by hand. It should turn freely. If it’s jammed or grinding, fish out the coin, hairpin, button or fibre that’s blocking it. A jammed impeller can read fine on continuity but still fail to pump, so always check both. Even though you’re fitting a new pump, knowing whether it was a jam or a burnt motor tells you if debris is getting past the filter.
Step 9, fit the new pump. Drop the genuine replacement pump into the same mounting position and secure the screws or clips. It’s a direct fit, so everything lines up with the original.
Step 10, reconnect hoses and wiring. Push the hoses fully onto the spigots and slide the spring clamps back into place. Reconnect the electrical plug until the tab clicks. Use your earlier photo to confirm everything is back where it was.
Step 11, refit the panel and stand the machine up. Screw the service or base panel back on and return the machine to its position.
Step 12, restore power and water, then test. Plug in, turn the taps back on, and run a short rinse/spin cycle with no clothes. Watch the drain phase: you should hear the new pump hum and see water leave through the drain hose, then the machine should advance into spin. Check under and behind the machine for leaks at the hose connections.
If it drains and spins cleanly with no leaks, the job’s done.
Genuine vs compatible, what should I buy?
For a part that handles every litre of dirty wash water and runs on mains power, go with the genuine Samsung pump. At $29.95 there’s little reason to gamble. Genuine means it’s the exact pump Samsung engineered for these top loaders: correct flow rate, correct mounting, correct connector, and it slots straight in without adapters. Cheaper no-name pumps can mismatch the impeller geometry or the electrical spec, which leads to weak draining, early failure, or connectors that don’t seat properly. A drain pump is a buy-it-once job. Fit the genuine part and you won’t be back inside the machine for years.

How much is the Samsung drain pump?
The genuine Samsung drain pump is $29.95 from our Sydney warehouse, with same-day dispatch on orders placed before our daily cut-off.
Is this a genuine Samsung part?
Yes. We supply the genuine Samsung drain pump, the same component fitted at the factory, not a generic copy. It’s a direct plug-in replacement.
Will this drain pump fit my Samsung top loader?
It fits Samsung top-loader washing machines originally fitted with this pump. The surest check is to read the part number printed on your existing pump and match it against the number in the listing title, or confirm your model number against ours using the part finder. If your old pump’s number matches the listing, this is the correct part.
Can I replace the drain pump myself?
Yes. It’s a common DIY repair that takes most people 30 to 45 minutes with a screwdriver, pliers and a multimeter. The non-negotiables are unplugging the machine, turning off the water, and catching the trapped water with towels. If you’re not comfortable working near mains wiring, have a technician fit it.
How long does delivery take?
We dispatch the drain pump same-day from our Sydney warehouse on orders placed before the daily cut-off, so most Australian metro customers receive it within a couple of business days.
My machine still won’t drain after I replaced the pump, what now?
Re-check the basics: a kinked or blocked drain hose, a clogged standpipe, or debris caught at the pump inlet will all stop drainage even with a brand-new pump. If the machine drains but still won’t spin, work through our companion guide on a Samsung washing machine that’s not draining for the full fault tree.
Why did my old drain pump fail?
Drain pumps fail two ways: the motor winding burns out over years of use (an open circuit on a continuity test), or the impeller jams on a coin, hairpin or sock fibre. If yours was jammed, check your pump filter and pockets before each wash to stop it happening to the new pump.
