Standing water in the tub
There is a pool of dirty water under the lower rack or around the filter area after the cycle stops.
Start here: Remove the water first, then clean the filter and sump so you can see what is actually blocking flow.
Direct answer: A Samsung dishwasher 5C or 5E code usually means the machine tried to drain and the water did not leave fast enough. Most of the time the cause is standing water, a clogged filter area, a kinked dishwasher drain hose, or a blockage where the hose ties into the sink drain or air gap.
Most likely: Start with the easy drain path: remove the water, clean the dishwasher filter and sump area, then check the dishwasher drain hose and the sink-side connection for a clog.
If there is water sitting in the tub, treat this like a drain restriction until proven otherwise. Reality check: a lot of 5C and 5E calls end with food sludge in the filter well or a plugged sink-side fitting. Common wrong move: running cycle after cycle with standing water still in the bottom, which just leaves more debris packed into the drain path.
Don’t start with: Do not start by ordering a dishwasher drain pump. Pumps do fail, but on this code a plain blockage is more common.

The dishwasher seems to wash normally, then throws 5C or 5E when it should be draining out.
Start here: Check the drain hose route and the sink-side connection, because that is when a partial clog usually shows up.
You hear the drain attempt, but the water level hardly drops.
Start here: Look for a clogged filter well, debris in the sump, or a restricted dishwasher drain hose before suspecting an internal part.
The tub looks mostly empty, yet the code comes back after reset or another cycle.
Start here: Check for a slow drain path, a high-loop or hose issue, or a float area problem that can confuse the machine about water level.
This is the most common cause when the tub holds water and the code appears after a cycle. Food scraps, labels, glass bits, and grease collect right where the dishwasher starts draining.
Quick check: Pull the lower rack, remove the filter pieces if accessible, and look for sludge or hard debris in the well below.
A hose that is pinched behind the machine or packed with grease can let a little water through but not enough to satisfy the drain timing.
Quick check: Inspect the visible hose path under the sink for sharp bends, sagging, or a clog at the connection point.
If the dishwasher drains into an air gap or a branch tailpiece on the sink, that fitting can clog and make the dishwasher act like it has an internal problem.
Quick check: If you have an air gap on the sink deck, pop the cap and check for debris. If not, inspect the dishwasher hose connection at the sink drain.
This moves up the list only after the drain path is clear. A weak or jammed pump may hum, click, or move very little water even with no visible blockage.
Quick check: After clearing the filter and hose path, run a drain cycle and listen for a strong rush of water versus a weak hum or grinding sound.
You want to separate a dishwasher blockage from a kitchen drain problem before pulling parts or opening the machine.
Next move: If the sink drain issue is corrected and the dishwasher drains normally after that, the dishwasher itself likely does not need parts. If the sink drains fine but the dishwasher still holds water, move to the filter and sump area.
What to conclude: A 5C or 5E code can be caused by the dishwasher's own drain path or by the plumbing connection it drains into. Separating those early saves time.
You cannot judge the drain system well with dirty water covering everything. Most no-drain calls start and end here.
Next move: If the dishwasher drains normally after reassembly, the code was caused by a clogged filter or sump. If the code returns or the water still drains slowly, check the hose path next.
What to conclude: A packed filter or blocked sump starves the drain system right at the source. Even a good pump cannot move water through a plugged intake area.
Once the filter area is clear, the next most common restriction is the hose or the fitting where it ties into the sink drain.
Next move: If water now rushes out strongly during a drain cycle, the restriction was in the hose or sink connection. If the hose path is clear and the dishwasher still barely drains, the pump or an internal blockage becomes more likely.
This is where you decide whether the machine has a real internal drain failure instead of a plain blockage.
Next move: If the pump suddenly moves water strongly after debris is cleared, reassemble and run a short cycle to confirm the fix. If the pump still hums weakly or does not move water with a clear path, the dishwasher drain pump is the leading suspect.
The last step is to leave the machine either fixed and verified or shut down cleanly until the right repair is made.
A good result: If the tub ends the cycle with only a thin film of water near the sump and no code returns, the repair path was correct.
If not: If the code returns with a clear drain path and no obvious pump issue, professional diagnosis is the safer next move because internal wiring, sensors, or control faults are less common and less DIY-friendly.
What to conclude: You have narrowed the problem to either a cleared blockage, a failed dishwasher drain hose, or a likely dishwasher drain pump issue.

It usually means the dishwasher did not drain the water out in the expected time. In plain terms, the machine sees a drain problem, most often from a clog or restricted hose path.
For practical troubleshooting, yes. Homeowners usually treat both as a drain error and start with standing water, the filter, the sump area, the drain hose, and the sink-side connection.
You can try a reset, but if water is still in the tub the code usually comes back. Resetting does not clear a clogged filter, blocked hose, or plugged sink connection.
A partial clog can let some water out but not fast enough. The tub may look almost empty, yet the dishwasher still sees a slow-drain condition and throws the code.
Suspect the dishwasher drain pump after the filter, sump, hose, and sink connection are confirmed clear. A weak hum, grinding, or little to no water movement with a clear drain path points that way.
Yes. If the dishwasher drains into a blocked sink branch or air gap, the dishwasher can act like it has an internal failure even though the real restriction is on the sink side.
