Et
Samsung Dryer
Severity: CriticalWhat Does This Error Mean?
The Et error means your Samsung dryer has detected a problem with its electrical input. The machine is not receiving the correct voltage to operate safely. This error requires immediate attention — do not keep running the dryer.
Affected Models
- DV42H5200EW
- DV48J7770EW
- DV50K8600EV
- Most Samsung electric dryers
Common Causes
- Only one leg of the 240V supply is live — the other has failed
- The dryer's power cord is damaged or incorrectly wired
- A circuit breaker has partially tripped — one pole is off
- The wall outlet contacts are loose or corroded
- The terminal block inside the dryer is loose or burned
How to Fix It
-
Turn off the dryer immediately and unplug it.
A 240V power fault is a safety hazard — stop use right away.
-
Go to your circuit breaker panel and find the dryer's double-pole breaker.
It should be a two-slot breaker. If either side is tripped or loose, reset both sides firmly.
-
Visually inspect the power cord at the back of the dryer.
Look for scorch marks, melted insulation, or loose connections at the terminal block. Do not touch bare wires.
-
If the breaker and cord look fine, call an electrician to test the outlet.
A 240V outlet can lose one phase without any visible sign — only a meter test will confirm it.
-
Do not plug the dryer back in until the power supply has been verified as correct.
Running a 240V dryer on 120V can burn out the heating element and motor.
When to Call a Professional
Electrical issues on a 240V appliance are dangerous to diagnose yourself. Always call a qualified electrician or appliance technician for Et errors. Do not use the dryer until the power supply is confirmed safe. Repair costs: $80–$250 depending on whether the issue is the outlet, cord, or terminal block.
Frequently Asked Questions
Why does Et only appear on electric dryers, not gas?
Gas dryers use 120V for controls and ignition only. Electric dryers use 240V for the heating element. Et specifically relates to the 240V supply that electric dryers need.
Can I reset Et by just flipping the breaker?
Sometimes. If a partial trip is the cause, resetting the breaker fixes it. But if the outlet, cord, or terminal block is faulty, Et will return. Always have the wiring checked if it comes back.
Is Et dangerous to ignore?
Yes. Running a dryer on incorrect voltage can damage the motor and heating element. It also creates a risk of overheating or electrical fire. Stop using the dryer until the issue is resolved.
