What does the SC error mean on a Samsung dishwasher?

The SC error code indicates a drainage issue where your dishwasher is unable to empty water effectively.

You might also see this error displayed as 5C, SE, or 5E depending on the font of your digital panel. While the exact diagnostic meaning can vary slightly by model line, it consistently points to restricted water flow during the drain cycle.

SC stands for a slow drain or complete failure to drain water entirely.
Water remains pooled unpleasantly at the bottom of your internal dishwasher tub.
The digital display may interpret the letter S as the number 5.
This error halts the current wash cycle to prevent overflowing the kitchen floor.
Check your specific owner’s manual to confirm the code variation for your unit.

Why is my Samsung dishwasher not draining?

Drainage failures are typically caused by physical blockages in the filter, drain hose, or home plumbing.

Food particles, grease buildup, and broken glass often accumulate over time, severely restricting water movement through the appliance. Always turn off the dedicated circuit breaker before reaching into standing water to safely investigate these common plumbing culprits without risking a severe electric shock.

A congested drain pump filter blocking dirty water from leaving the internal tub.
Kinked or crushed flexible drain hoses installed awkwardly behind the heavy appliance.
A newly installed garbage disposal unit still containing an intact plastic knockout plug.
Clogged kitchen sink plumbing preventing the dishwasher from pushing waste water out.
A jammed or failing drain pump impeller struggling to spin against hard debris.

What quick fixes should I try first?

Start by clearing the filter assembly and checking your kitchen sink drain for obvious physical blockages.

These basic steps solve the majority of drainage problems without requiring any specialized tools or plumbing experience. Before starting, unplug the dishwasher or switch off the dedicated circuit breaker for your personal safety to avoid any risk of electric shock.

Run the kitchen sink faucet to ensure your house plumbing is draining normally.
Scoop out any standing dirty water inside the dishwasher tub using a plastic cup.
Twist the cylindrical drain filter counterclockwise and lift it out of the housing basin.
Wash the filter assembly thoroughly under warm running water with mild liquid dish soap.
Reinstall the clean filter by twisting it clockwise until it locks tightly in place.

How do I clear a deep clog in the drain hose?

Inspect and clear the drain hose connection where it meets your sink or garbage disposal.

If the filter is clean but the error persists, the restriction is likely trapped in the exit plumbing path. Keep a dry towel and a shallow bowl ready to quickly catch any trapped water during this disconnection process to prevent floor damage.

Verify the dishwasher power is completely shut off at the main household breaker panel.
Loosen the metal hose clamp holding the corrugated dishwasher hose to the sink plumbing.
Pull the hose off the plumbing connection and check the dark opening for debris.
Clear out any accumulated gunk using a straightened wire coat hanger or flexible brush.
Run water through the disconnected hose end into a large bucket to test flow.
Reattach the drain hose securely to the plumbing fixture and tighten the metal clamp.

Quick reference table for drainage symptoms

Match your specific observation to the most likely cause to speed up your repair process.

Different drain failure characteristics can point you directly toward the exact component that needs your immediate attention. Use this quick reference chart to narrow down where you should spend your troubleshooting time before attempting to pull the entire machine out from the cabinets.

Symptom	Likely cause / fix
Water pools after one cycle	Clean the clogged drain filter
Sink also drains slowly	Clear the house plumbing blockages
New disposal was installed	Remove the disposal knockout plug
Loud grinding noise heard	Remove broken glass from the drain pump
No noise during drain phase	Inspect for a faulty drain pump motor

When should I stop and call a repair technician?

Stop DIY repairs if you need to dismantle internal sealed components or test live electrical boards.

While clearing external hoses and wiping out filters is completely safe for most homeowners, testing internal components requires professional training. Unplug the appliance immediately and call for experienced backup if you encounter these specific red flags during your repair attempt.

The lower drain pump completely fails to activate and makes absolutely no sound.
You discover a severe ongoing water leak originating from under the heavy dishwasher.
Accessing the required broken part involves testing dangerous high-voltage electrical control boards.
The internal corrugated drain hose has a large tear and requires a full replacement.
You smell burning plastic or dangerous electrical odors near the operating kitchen appliance.

What do I need before calling appliance support?

Gather your appliance details and note down the exact symptoms to ensure a faster service visit.

Having the right information ready prevents annoying delays and helps the technician bring the correct replacement parts on the first trip. Always mention the exact error code you saw on the control panel so they know what they are dealing with.

Locate your specific appliance model and serial number on the inner stainless door edge.
Check your purchase receipt to verify if the dishwasher is still under manufacturer warranty.
Write down the exact letters or numbers shown flashing on the digital control display.
Document every single troubleshooting step you have already attempted yourself prior to calling.
Note if the drainage failure happens during every cycle or only occasionally over time.

How do I prevent the SC drain error from returning?

Maintain a clear drain path by properly preparing your dishes and cleaning the filter monthly.

Consistent routine maintenance is the absolute easiest way to prevent drainage errors and keep your appliance smelling fresh all year. Incorporate these simple preventative habits into your regular kitchen cleanup routine to protect the drain pump from unnecessary wear and tear.

Scrape large sticky food particles directly into the trash before loading your dirty dishes.
Avoid rinsing plates completely clean to allow the enzyme detergent to work properly.
Remove and rinse the bottom plastic drain filter under the tap at least monthly.
Run your garbage disposal system briefly before starting a brand new dishwasher cycle.
Use a commercial dishwasher cleaning tablet to dissolve hidden grease buildup in the lines.

Frequently Asked Questions

Does the SC error code mean the drain pump needs to be replaced?

Not necessarily. In most cases, the SC code is triggered by a simple clog in the filter or the external drain hose, which you can fix for free. A drain pump replacement is only required if the pump motor has burned out electrically or the internal impeller is physically shattered. Always check for blockages before buying new parts.

Why am I getting an SC code when there is no standing water in the tub?

This usually happens if the water level sensor, also known as a pressure switch, is dirty or malfunctioning. The sensor mistakenly tells the control board that the dishwasher is full of water, triggering the drain error. Cleaning the sensor tube or replacing a faulty pressure switch often resolves this confusing symptom. Check your owner’s manual for sensor location.

How do I clear the SC error on my Samsung dishwasher after fixing the clog?

Once you have removed the blockage and reassembled the components, you need to reset the control board to clear the error state. Simply turn off the dishwasher and unplug it from the wall, or flip the circuit breaker off for about three to five minutes. Restore the power and run a quick rinse cycle to verify the code is gone.

Will a kinked hose behind the dishwasher cause an SC error?

Yes, a kinked or crushed drain hose is one of the most common installation issues that lead to drainage errors. If the dishwasher was recently pushed back too tightly against the wall or cabinets, the flexible hose can pinch completely shut. Pulling the unit out slightly and inspecting the hose routing behind the machine can instantly fix the problem.

Can a clogged air gap on my sink cause this Samsung error code?

bsolutely. If your kitchen plumbing setup uses a countertop air gap, any debris trapped inside the cap will stop the dishwasher from discharging water. You can easily fix this by popping off the decorative metal cover on your sink and using a small bottle brush to clear out accumulated food sludge from the plastic vents inside.

Bottom Line

Finding an SC error code on your Samsung dishwasher is inconvenient, but checking the filter and sink connections resolves the issue most of the time. If clearing the basic drain path doesn’t get the water flowing out again, leave the power off and consult a certified appliance repair professional.
