Samsung Dishwasher 5C Error: Drain Fault (Older Display)

Quick Answer

The 5C error code on a Samsung dishwasher indicates a drainage fault. The most common fix is cleaning the drain filter and checking the drain hose for clogs.

The 5C code means water's sitting in your tub after a drain cycle timed out and gave up. Ignore it and the machine won't finish any cycle at all, and eventually you risk water backing up past the door seal. When I walk into a house with this code, nine times out of ten the fix is a gunked-up filter or a kinked hose. Usually free to fix and done in 20 minutes.

What Does the 5C Code Mean?

When I see this code on a Samsung, I look for standing water first. If the tub's full, the machine failed its timed drain. These units are actually pretty sensitive to high-loop issues on the drain hose and grease buildup in the check valve. It's a frustrating code when it keeps coming back, but honestly the fix is usually cheap and you probably won't need a part at all.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Drain pump mesh cover clogged with plastic film or debris40%

Filter basket blocked with food accumulation24%

Drain hose kinked or pinched14%

Pump motor burned out12%

Drain pump impeller jammed by foreign object10%

Symptoms You May Notice

You open the door after a cycle and there's a half inch of murky water sitting at the bottom of the tub that never drained.
5C code flashes on the display right at the end of a wash or rinse phase, just before the final drain would have run.
You can hear the pump trying to drain but the sound cuts off after 10-15 seconds instead of running until the tub is fully empty.
Machine locks up mid-cycle and won't respond to button presses for a couple minutes.
Dishes come out wet and still greasy, like the rinse never actually happened because the machine stalled before it could start that phase.

Can you reset a Samsung dishwasher to clear the 5C code?

Press and hold the Start or Cancel button for 3 seconds to force a reset. You'll hear the drain pump kick on right away if the water level sensor still sees water in the tub. If 5C comes back within a minute, the sensor's still reading high water. Scoop out whatever standing water is left by hand first, then try the reset again. After the tub clears, run a short rinse cycle to confirm the code is gone.

Frequently Asked Questions

Is 5C the same as SC on Samsung dishwashers?

Yes, they're essentially the same code. Samsung changed the display characters on newer models, but the underlying logic is identical. A 5C on an older unit and an SC on a newer one both point to the drain system failing to clear the tub in time. If you find a repair guide for SC, you can follow it step by step for your 5C error without any issues. Same causes, same fixes, same parts.

How often should I clean the Samsung dishwasher filter to prevent 5C?

Every two weeks if you don't pre-rinse your dishes. That's honestly the answer. For the 5C code specifically, the real culprit is usually the fine mesh screen under the main filter, not the filter itself. Give that area a quick sweep with a brush once a month. I tell every customer the same thing: pull that filter on the 1st and 15th of each month, takes 5 minutes, and you'll probably never see this code again.

How much does a Samsung dishwasher drain pump cost to replace?

The drain pump for most Samsung dishwashers, part number DD31-00005A or DD31-00030A depending on your specific model, runs $25 to $45 online. Local appliance parts store will probably charge you $55 to $65 for it. If you hire someone, figure one hour of labor on top of that, so $110 to $160 all in. The pump is actually pretty accessible from the bottom of the machine. Most people with zero repair experience can swap one in about 45 minutes following a YouTube walkthrough.

Can I use my dishwasher while it's showing the 5C error?

The machine won't let you, basically. It locks up and refuses to complete a cycle. You can try pressing Start to force a partial drain, but honestly don't keep running it. Running the pump repeatedly against a blockage heats up the motor windings and can burn them out, which turns a free filter-cleaning job into a $40 pump replacement. Just spend 20 minutes clearing the filter first. It's almost always the answer anyway.

How do I tell if it's a clog or a dead pump motor?

Listen during the drain phase. A blockage usually sounds like a grinding, buzzing, or laboring hum that stops before all the water's gone. A dead motor is just silence when you should hear pumping. You can also reach into the sump with the power off and try spinning the impeller blade by hand. It should rotate with light resistance. Doesn't move at all means something's jammed in there. Spins freely but the motor still won't run means the motor windings are shot and you need a new pump assembly.

Why does the 5C error keep coming back even after I clean the filter?

Almost always a drain hose routing problem. If the hose doesn't have a proper high loop under the counter, water from your sink drain siphons back into the dishwasher tub every time the sink drains. Clean filter or not, the machine just keeps filling back up and triggering 5C. Check that the drain hose rises up to at least the bottom of the counter before it drops down to the P-trap. Some plumbers skip the high loop entirely and it causes exactly this problem. Fix it with a zip tie and a mounting clip in about two minutes.
