4E
Samsung Dishwasher
Severity: ModerateWhat Does This Error Mean?
The 4E error means your Samsung dishwasher is not getting enough water. The machine tried to fill but water flow was too low or absent. This is almost always a water supply issue, not a broken dishwasher.
Affected Models
- DW80R5061US
- DW80R9950UG
- DW80N3030US
- DW80J3020US
- Most Samsung built-in dishwashers
Common Causes
- The water supply valve under the kitchen sink is turned off or partially closed
- The water inlet hose is kinked or bent
- The inlet hose filter screen is clogged with mineral deposits
- The water inlet valve inside the dishwasher is faulty
- Low household water pressure (below 20 PSI)
How to Fix It
-
Check the water supply valve under the kitchen sink.
Follow the thin hose from the dishwasher to the valve. Make sure it's fully open (turned counterclockwise).
-
Inspect the water inlet hose for kinks or bends.
Pull the dishwasher out slightly if needed. Straighten any kinks you find.
-
Clean the inlet hose filter screen.
Turn off the water supply first. Disconnect the hose from the dishwasher. Remove the small mesh screen and rinse it clean.
-
Run the kitchen sink faucet to check water pressure.
If the flow is weak at the sink too, the issue is your home's water pressure.
-
Press the Start button to restart the dishwasher cycle.
If the error returns, the water inlet valve inside the dishwasher may need replacement.
When to Call a Professional
If you've checked the supply valve and hoses and the error persists, the water inlet valve may be faulty. A technician can test and replace it. Expect repair costs of $100–$200 including parts and labor.
Frequently Asked Questions
What does 4E mean on a Samsung dishwasher?
It means the dishwasher is not receiving enough water to run. The machine detects low or no water flow. It's usually a supply issue like a closed valve or clogged filter.
Can I fix the Samsung dishwasher 4E error myself?
Yes, in most cases. Check the water supply valve under the sink first. Then inspect the hose for kinks and clean the filter screen. These simple fixes solve the problem about 80% of the time.
Why does my Samsung dishwasher show 4E after installation?
The water supply valve may not be fully open. The installer might not have turned it on all the way. Check the valve under the sink and open it completely. Also make sure the inlet hose isn't crimped behind the dishwasher.
