Samsung Dishwasher CE Error Code
Over-temperature or inlet water too hot
What this error means
CE on Samsung dishwashers frequently groups with 4C2—extremely hot water entering the cold inlet because supply hoses are swapped. The board aborts fill to protect seals and plastic sump components.
How CE is detected
When CE appears on a Samsung dishwasher, the control board has confirmed that water did not leave the machine within the programmed drain window. On Samsung DW80R5060US, Samsung DW80B7070US, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most CE calls are resolved without parts: confirm blue/cold hose to cold inlet and hot to hot per label on the valve. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If CE returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Hot and cold supply lines reversed under the sink
- Water heater set above 140 °F feeding the dishwasher inlet
- Failed inlet thermistor reading falsely high
- Stuck fill valve letting steam backflow on rare installs
Step-by-step fixes
- 1Confirm blue/cold hose to cold inlet and hot to hot per label on the valve
- 2Run cold at the sink—if scalding, fix plumbing before retrying dishwasher
- 3Lower water heater to 120 °F per energy guidelines
- 4Power-cycle after correcting hose routing—CE should not return
When to call a technician
Correct plumbing with repeating CE suggests inlet thermistor or main PCB fault.
Affected models
- Samsung DW80R5060US
- Samsung DW80B7070US
- Samsung DW80R7031US
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dishwashers to prevent CE from lint and food debris buildup.
- Record when CE appears in the cycle and whether it clears after a 60-second power reset on your Samsung dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for CE; Samsung uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting CE; reversed plugs on pumps and valves cause immediate repeat faults.
