What Does Error Code 3C Mean on a Samsung Dishwasher?

Wash motor error — circulation pump failure.

The control board monitors the circulation pump motor's speed and current feedback while it should be spraying water during the wash phase. 3C (also shown as 3E) fires when the motor stalls, draws abnormal current, or returns no rotation signal — often from a jammed impeller or failed winding. This distinguishes it from drain-pump faults like 5C, which involve water not leaving the tub rather than the wash motor itself failing to circulate.

Models affected: Samsung dishwashers using the 3C/3E code family, including models such as DW80R5060US, DW80K5050US, DW80B6060US, and DW80CG4051SR
What owners report: Owners commonly report this code appearing shortly after a cycle starts or after a glass has broken inside, with water not spraying and dishes left dirty. A frequent quick win is clearing debris lodged in the sump or impeller and power cycling; if the code returns after a clean pump, the motor itself is usually at fault.

What Causes Error Code 3C?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Failed circulation pump motor 55% of cases
  2. 2
    Foreign object (broken glass, bone) jammed in pump impeller 30% of cases
  3. 3
    Control board motor relay failure 15% of cases

How to Fix Samsung Dishwasher Error Code 3C

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check for debris in the pump

    Remove the filter assembly and reach into the sump area. Feel around the pump impeller for any hard debris. Remove carefully.

    ⚠️ Sharp broken glass may be present — use gloves.
  2. 2

    Power cycle the dishwasher

    Disconnect power for 5 minutes and restart. If the pump jammed briefly, a reset may clear it.

  3. 3

    Test the pump motor

    Access the pump from under the dishwasher. Test the motor windings with a multimeter. No continuity indicates a burned motor.

Frequently Asked Questions

Can I keep using my Samsung Dishwasher when error 3C appears? +
It is not advisable. The dishwasher may still power on, but running it while 3C is active can worsen the motor fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes 3C on a Samsung Dishwasher? +
Across reported Samsung dishwasher repairs, the most frequent is failed circulation pump motor (55% of cases), foreign object (broken glass, bone) jammed in pump impeller (30%), then control board motor relay failure (15%). Check them in that order before replacing any parts.
3C keeps coming back after a reset — what should I check next? +
A reset only clears the stored 3C fault; if it returns, the motor problem is still present. Move on to the physical checks — check for debris in the pump, then power cycle the dishwasher — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix Samsung Dishwasher error 3C? +
A DIY repair typically runs $100–$250 in parts, versus $250–$450 for a professional service call, so handling it yourself saves around $150. Expect the work to take 1–3 hours.
Which Samsung Dishwasher models show error 3C? +
3C is documented on Samsung dishwashers using the 3C/3E code family, including models such as DW80R5060US, DW80K5050US, DW80B6060US, and DW80CG4051SR. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
