What does the Samsung 5C / SC error code mean?
The 5C code (which can look like ‘SC’ on some displays) is Samsung’s drainage fault code. The dishwasher has detected that it cannot pump out the waste water. As with most dishwasher drainage errors, the cause is typically a blocked filter, a jammed pump impeller, or a kinked drain hose.
🔍 Symptoms
- Water visible in the bottom of the dishwasher tub after cycle ends
- Machine pauses and displays 5C or SC
- Drain pump can be heard running but no water is expelled
- Cycle does not complete — machine stops at the drain phase
- Dishes remain dirty and wet after the programme finishes
How to fix the Samsung 5C / SC error code
- Open the door carefully — standing water may be present. Use towels to protect your floor.
- Remove the lower basket and locate the filter assembly at the base of the machine. On Samsung models, this is usually a twist-lock cylindrical filter. Clean it under warm running water.
- Remove the filter cover and check the drain pump impeller — visible through the filter housing. Remove any debris jamming the impeller blades.
- Check the drain hose at the rear of the machine for kinks or obstructions.
- Run a Rinse programme to test. If 5C persists, the drain pump motor itself may be faulty and require replacement.
Frequently Asked Questions (FAQ)
Q: Why does my Samsung dishwasher show SC instead of 5C?
A: On certain Samsung display types, the number ‘5’ can be mistaken for the letter ‘S’, particularly on older LED segment displays. 5C and SC are the same fault code.
Q: My Samsung dishwasher drains fine into a bucket when I test the hose — but still shows 5C. Why?
A: If the hose flows freely, the issue is likely inside the machine — either a partly blocked impeller slowing drainage below the required rate, or a faulty pump motor that cannot generate sufficient pressure.
Q: How do I reset the 5C error on my Samsung dishwasher?
A: After fixing the cause, press and hold the Start/Reset button for 3 seconds. If this does not clear it, try switching the machine off at the wall for 5 minutes.
