Samsung Dishwasher 3C Error Code: What It Means & What to Check
If your Samsung dishwasher is showing 3C, it commonly points to a pump operation error. In plain English: the dishwasher isn’t sensing normal pump performance (washing/circulating water and/or draining). Start with the safe checks below.
Q: What does 3C mean on a Samsung dishwasher?
A: 3C typically indicates a pump operation error. Power cycling and checking for obstructions (filters, sump area, drain path) are good first steps. If the code returns, the issue may involve the drain pump or circulation pump, wiring, or the control.
Symptoms You May Notice
- The dishwasher stops mid-cycle and displays 3C
- Very little “spray” sound after filling
- Water remains in the bottom of the tub
- It drains briefly, then errors again
Safety First
- Turn power off at the breaker (or unplug if accessible) before reaching into the sump/filter area.
- Use towels for water—avoid reaching near electrical connections while power is on.
- Skip internal pump disassembly unless you’re qualified (sharp debris and electrical hazards are common).
Quick Checks You Can Do Now
- Power cycle: Turn the dishwasher off, wait 60 seconds, then turn it back on and restart the cycle.
- Listen for pump action: After filling, you should hear a steady wash/spray sound. Near the end, you should hear strong draining.
- Clean the filter(s): Remove and rinse the filter(s) at the bottom of the tub.
- Check the sump area for obstructions: Look for labels, toothpicks, broken glass, bone fragments, etc.
- Check the drain path: Ensure the drain hose isn’t kinked and the sink/disposal connection is clear.
- Run a short test cycle empty: Confirm it fills, sprays, and drains normally.
Tip: If it fills but you never hear strong spraying, that leans toward a circulation issue. If it washes but won’t empty the tub, that leans toward a drain-side issue.
Common Causes (and Likely Parts)
- Filter/sump blockage restricting water movement
- Drain restriction (hose kink, disposal/air-gap clog, blockage at connection)
- Drain pump struggling or failing
- Circulation (wash) pump weak, jammed, or failing
- Wiring/connector issue to a pump (intermittent power/feedback)
- Main control (less common; usually after pumps/wiring are ruled out)

FAQ: Samsung Dishwasher 3C
Is 3C always a drain pump problem?
No. 3C is a pump operation error and can relate to either circulation (wash) or drain behavior depending on when it happens.
What’s the first thing I should do when 3C appears?
Power cycle the dishwasher and restart the cycle. If it returns, clean the filters and check for obvious obstructions.
Can a dirty filter trigger 3C?
It can contribute. Restricted flow can strain pump operation and cause the dishwasher to fault.
The dishwasher fills but I don’t hear spraying—what does that mean?
That pattern often points toward a circulation (wash) pump issue or a blockage affecting circulation.
The dishwasher washes but leaves water in the bottom, then shows 3C.
That pattern commonly points to a drain restriction or a weak drain pump.
When should I call Beacon?
If 3C returns after a reset and basic filter/obstruction checks, schedule service so our friendly technicians in yellow can diagnose the pump, wiring, or control safely.
