8E
Samsung Dishwasher
Severity: CriticalWhat Does This Error Mean?
The 8E error means your Samsung dishwasher has detected a water leak. A leak sensor in the base of the machine has been triggered. The dishwasher shuts down automatically to prevent floor damage.
Affected Models
- DW80R9950UG
- DW80R5061US
- DW80K7050US
- Most Samsung built-in dishwashers with leak detection
Common Causes
- A door seal or gasket is worn, cracked, or misaligned
- The dishwasher is not level — water tilts and escapes
- Too much detergent caused excessive suds and overflow
- A hose connection inside the machine has come loose
- The leak sensor itself is wet from a past incident and hasn't dried
How to Fix It
-
Turn off the dishwasher and cut the water supply valve under the sink.
This stops any further water entering the machine.
-
Pull the dishwasher out slightly and look for water on the floor.
Wipe up any standing water with towels before continuing.
-
Inspect the door gasket all the way around for cracks or gaps.
A worn gasket is the most common cause of 8E. Press it back into the groove if it's fallen out.
-
Check that the dishwasher sits level on the floor.
Use a spirit level. Adjust the front legs if needed — they twist to raise or lower.
-
Switch to a dishwasher-specific detergent and use the correct amount.
Hand dish soap causes heavy suds that can trigger the leak sensor.
When to Call a Professional
If you see actual water under or around the dishwasher, stop using it. A technician can identify the exact leak source safely. Repair costs typically range from $100 to $300 depending on the part. Ignoring a water leak can cause serious floor and cabinet damage.
Frequently Asked Questions
Why does 8E appear even when I don't see a leak?
The leak sensor sits in the base tray of the dishwasher. Even a tiny amount of water reaching that tray triggers 8E. The leak might be internal and not visible from outside.
How do I dry out the leak sensor?
Tilt the dishwasher slightly forward to let water drain from the base tray. Leave it unplugged for 24–48 hours to dry fully. Then reset and run a short cycle to test.
Can I fix the door gasket myself?
Yes, in most cases. Replacement gaskets are available online for $20–$50. The gasket presses or clips into a channel around the door frame. No tools are usually required.
