2E
Samsung Dishwasher
Severity: ModerateWhat Does This Error Mean?
The 2E error means your Samsung dishwasher has a water supply fault. The machine tried to fill but didn't get enough water. This usually points to a supply problem before water ever enters the machine.
Affected Models
- DW80R5061US
- DW80R2031US
- DW80N3030US
- Most Samsung built-in dishwashers
Common Causes
- The water supply valve under the sink is partially or fully closed
- The inlet hose is kinked, pinched, or blocked
- The water inlet valve on the dishwasher itself is faulty
- Low household water pressure — below 20 psi is too low
- The door latch didn't close fully, so the fill cycle never started
How to Fix It
-
Check the water supply valve under your kitchen sink.
It should be fully open — turn it counterclockwise all the way.
-
Inspect the water inlet hose at the back of the dishwasher.
Look for kinks, sharp bends, or visible damage. Straighten any kinks.
-
Turn off the dishwasher at the wall. Wait 5 minutes, then restart.
A power reset clears temporary faults in the control board.
-
Run a different water tap in your home to check household pressure.
If water flow is weak everywhere, the issue is with your home supply — not the dishwasher.
-
Close the door firmly and listen for a click from the latch.
A door not fully closed will prevent the fill cycle from starting.
When to Call a Professional
If the water inlet valve needs replacing, a technician is recommended. The valve is inside the machine and requires partial disassembly. Repair costs are typically $100–$200 including parts and labor. Do not force-run the dishwasher with standing water inside.
Frequently Asked Questions
Can I run the dishwasher while 2E is showing?
No. The machine won't fill properly and may skip wash cycles entirely. Fix the water supply issue first, then restart.
Is 2E the same as 4E on Samsung dishwashers?
They are related but different. 2E is a water supply fault at the source. 4E means the machine detected no water flow after trying to fill. Both often have the same root cause.
How do I reset a Samsung dishwasher?
Unplug the dishwasher from the wall outlet. Wait 5 full minutes, then plug it back in. This clears most temporary error codes.
