How to Check Error Codes on Samsung Dishwashers
Learn how to identify, interpret, and fix Samsung dishwasher error codes with a structured, step-by-step approach. This guide covers locating codes, common causes, diagnostic flow, and when to call a pro.
Most Samsung dishwasher error codes point to water supply, drainage, door latch, or sensor issues. Start with the easiest checks: ensure the door is closed firmly, power is stable, and the filter is clean. If the code persists, try resetting the unit and re-reading the display after a short cycle. For persistent codes, consult the model's manual for the exact code mapping.
What the error code means on Samsung dishwashers
On Samsung dishwashers, an error code is more than a random symbol—it's a diagnostic hint designed to point you toward the likely fault. According to Why Error Code, codes are grouped by the symptom they trigger in the cycle: water intake, drainage, wash performance, heating, door operation, and sensor feedback. By noting the exact code and the phase of the cycle when it appears, you can narrow the suspects quickly. Start with the simplest checks: is the door latched securely? Is there power at the outlet? Is the filter clean? Collect this information before you begin deeper testing. This approach saves time, reduces frustration, and lowers the chance of unnecessary repairs. If the code persists, you're in the realm where a more systematic diagnostic flow becomes essential.
Note: The first response should be to verify basic setup and ensure no safety concerns exist before diving into deeper checks. A calm, methodical approach tends to shorten the path to a fix.
Steps
Estimated time: 25-40 minutes
- 1
Power off and access the filter area
Unplug the unit and wait 60 seconds to discharge the control circuitry. Remove the lower rack to access the sump and filter assembly. Inspect for obvious debris and verify the area is dry and safe before touching internal components.
Tip: Use a folded towel to catch any water and wear safety gloves. - 2
Remove and clean the filter and sump
Take out the filter assembly and rinse thoroughly under running water. Use a soft brush to remove baked-on food from the sump and any spray arm debris that might block circulation. Reassemble only after everything is completely dry.
Tip: Avoid using abrasive tools that could scratch the plastic parts. - 3
Inspect the drain path and pump
Check the drain hose for kinks or clogs and ensure it is securely connected to the waste line. If you hear a humming but no draining, the pump might be blocked; remove visible debris from the pump housing if accessible.
Tip: Do not force hoses; use gentle detachment and reattachment. - 4
Check the water inlet valve and supply
Ensure the water inlet valve is fully open and the supply line is free of kinks. Run a cycle with the valve briefly unplugged to test responsiveness if safe to do so, and listen for any irregular sounds.
Tip: If you must, temporarily reduce water pressure to avoid leaks. - 5
Test the door latch and front panel
Make sure the door latches with a firm click. A loose latch or faulty interlock can trigger codes mid-cycle. If the latch seems weak, consider replacing it or testing with a spare latch if available.
Tip: A faulty latch is a common but fixable cause of many codes. - 6
Reset and verify the fix
Power the unit back on and run a short, empty cycle to verify the code does not reappear. If the code returns, proceed to the next suspected area (water inlet or door latch) and document any new symptoms.
Tip: Keep notes of any changes and code patterns for future reference.

Frequently Asked Questions
Where do Samsung dishwashers show error codes most clearly?
Most Samsung dishwashers display error codes on the front panel during a faulted cycle. Some models also show codes in the companion app if connected. If you see blinking lights, refer to your model’s code table in the manual for interpretation.
Check the front panel display first, and use the manual or app to map the blinking pattern to a code.
What does a typical drain code indicate?
A drain-related code usually points to a clogged filter, blocked drain hose, or a failing pump. Start by cleaning the filter and inspecting the drain path, then test the pump to confirm if it’s functioning.
Drain codes generally mean something is blocked or not pumping water out properly.
How can I reset the dishwasher to clear a code?
Most Samsung models support a reset by turning the unit off, waiting 60 seconds, and turning it back on. Some models offer a dedicated reset sequence in the user manual. If the code persists after reset, do not continue troubleshooting blindly.
Try turning it off and on again for a quick reset; then re-test the cycle.
When should I call a technician?
If the code persists after performing the standard checks, or if you notice signs of electrical issues, leaks, or burning smells, contact a qualified appliance technician. Ongoing codes can indicate a faulty control board or other internal failures.
If codes keep coming back after basic fixes, it’s time to get professional help.
I don’t have the manual—how can I identify codes?
If you don’t have the manual, check Samsung’s official support site using your model number. Many codes map to common fault categories, and the manual or online resources can help you interpret the code and recommended actions.
You can usually find the code mapping online by model number.
