Understanding Samsung Drainage Error Codes
Samsung uses several codes to indicate drainage problems:
| Error Code | Meaning | Most Common Cause |
|---|---|---|
| 5C | Drainage error | Clogged filter or blocked drain |
| 5E | Drainage error (older models) | Same as 5C |
| SC | Drainage error (alternate display) | Same as 5C |
| OC | Water overflow/drainage issue | Drain problem or sensor fault |
These codes all point to the same basic issue: water isn’t leaving your dishwasher properly. The fix is usually the same regardless of which code appears. For official code definitions, see Samsung’s dishwasher error code page.
What You’ll Need
- Towels for water cleanup
- Soft brush or old toothbrush
- Flashlight
- Flat-head screwdriver (for some models)
Step 1: Clean the Samsung Filter System
Samsung dishwashers have a two-part filter system at the bottom of the tub.
Locating the filter:
- Remove the bottom dish rack
- Look at the center-bottom of the tub
- You’ll see a cylindrical filter with a handle or knob
Removing and cleaning:
- Turn the filter handle counterclockwise
- Lift out the cylindrical coarse filter
- Remove the fine mesh filter underneath (some models)
- Rinse both filters under hot running water
- Use a soft brush to remove stuck debris and grease
- Check the sump area (filter housing) for food particles
- Reinstall filters — fine mesh first, then coarse filter
- Turn clockwise to lock
Important: The fine mesh filter is where most clogs occur. Make sure to clean it thoroughly, not just the outer coarse filter.
Step 2: Check the Drain Hose
The drain hose connects your Samsung dishwasher to the garbage disposal or sink drain.
Under the sink, check for:
- Kinks or sharp bends in the hose
- Crushed sections where items are pressing on it
- Proper high loop near the top of the cabinet
Samsung drain hose requirements:
- Must loop at least 20 inches from the floor
- Should connect to an air gap or have a high loop
- Cannot be longer than 10 feet total
If the hose is kinked, straighten it. If it’s damaged, replacement hoses cost $15-25.
Step 3: Check Garbage Disposal Connection
If your Samsung dishwasher drains through the garbage disposal:
- Run the disposal for 20 seconds to clear it
- Check that the knockout plug was removed (new disposal installations)
- Look for buildup at the dishwasher inlet inside the disposal
The knockout plug issue: New garbage disposals come with a solid plug blocking the dishwasher drain inlet. If this wasn’t removed during installation, your dishwasher can’t drain. Use a screwdriver and hammer to knock it out from inside the disposal.
Step 4: Reset Your Samsung Dishwasher
After fixing the issue, reset the error code:
Method 1 — Power reset:
- Press and hold the Start button for 3 seconds to cancel the cycle
- Turn off the dishwasher at the breaker or unplug it
- Wait 5 minutes
- Restore power and run a test cycle
Method 2 — Control panel reset:
- Press Hi-Temp Wash + Start buttons simultaneously
- Hold for 3-5 seconds
- The display should reset
Step 5: Force a Drain Cycle
To manually drain standing water:
- Press the Start/Cancel button and hold for 3 seconds
- Wait 2 minutes for the drain cycle to complete
- If water remains, you may need to bail it out manually
Samsung-Specific Troubleshooting
Filter Location by Model Series
| Model Series | Filter Location | Filter Type |
|---|---|---|
| DW80R | Center bottom, twist-lock | Two-part (coarse + fine) |
| DW7000 | Center bottom, pull-up | Single cylindrical |
| StormWash | Center bottom, twist-lock | Two-part with self-clean |
| Linear Wash | Center bottom | Two-part |
Common Samsung Issues
Flapper valve stuck: Samsung dishwashers have a flapper valve in the drain path. Food debris can prevent it from opening fully. Access it through the filter housing and clean any obstructions.
Smart features interference: Wi-Fi connected Samsung dishwashers occasionally have software glitches. Try disconnecting from SmartThings and running manually.
Drain pump access: On Samsung models, the drain pump is accessed from the bottom. You’ll need to lay the dishwasher on its side or back to reach it — a job most homeowners prefer to leave to professionals.
When to Call Samsung Support
Contact Samsung or a technician if:
- Error code persists after cleaning filter and checking hose
- You hear no sound during the drain cycle (pump failure)
- Water is leaking under the dishwasher
- The control panel is unresponsive
Samsung support: 1-800-726-7864 or visit Samsung’s dishwasher support page
Warranty note: Samsung dishwashers typically have a 1-year parts and labor warranty. Check your warranty status online — some components (like the stainless steel tub) may have longer coverage.
Preventing Future Drainage Problems
- Clean the filter every 2-4 weeks (Samsung recommends monthly)
- Scrape dishes before loading — no pre-rinse needed
- Run hot water at the sink before starting a cycle
- Use Samsung-recommended detergent amounts
- Run the garbage disposal before each dishwasher cycle
FAQ
What does 5C mean on a Samsung dishwasher?
The 5C error code indicates a drainage problem — water isn’t leaving the dishwasher properly. The most common cause is a clogged filter. Clean the filter at the bottom of the tub, check the drain hose for kinks, and ensure the garbage disposal is clear.
How do I force my Samsung dishwasher to drain?
Press and hold the Start button for 3 seconds to cancel the current cycle and initiate a drain. Wait 2 minutes for draining to complete. If no water drains, the pump may not be functioning — check for error codes and clean the filter.
Where is the drain pump on a Samsung dishwasher?
The drain pump is located at the bottom of the dishwasher, underneath the tub. Accessing it requires removing the bottom panel and potentially laying the unit on its side. This is more complex than filter cleaning and may require professional service.
Why does my Samsung dishwasher keep saying 5C?
Recurring 5C errors usually mean the filter needs more thorough cleaning or there’s a persistent blockage. Remove both the coarse and fine mesh filters, clean the sump area completely, and check for debris in the drain hose. If the code keeps returning, the drain pump may be failing.
