8C
Samsung Washing Machine
Severity: CriticalWhat Does This Error Mean?
The 8C error means the MEMS sensor in your Samsung washer has detected a problem. The MEMS sensor monitors the drum's motion, vibration, and balance during spinning. When it fails or gives bad readings, the washer stops the cycle immediately. This is a more serious error that often requires professional repair.
Affected Models
- WF45R6100AW
- WF50R8500AV
- WF56H9100AG
- WF45T6000AW
- Samsung VRT and VRT Plus washers
Common Causes
- Faulty MEMS (Micro-Electro-Mechanical System) sensor that has failed internally
- Washer installed on an uneven or unstable floor surface
- Transport bolts left in place after installation — bolts must be removed before first use
- Loose or corroded wiring harness connecting the sensor to the control board
- Control board malfunction misreading signals from the MEMS sensor
How to Fix It
-
Unplug the washer from the wall and wait 2 minutes.
A power reset sometimes clears a false 8C reading caused by a temporary sensor glitch.
-
Check that the washer is sitting perfectly level on the floor.
Use a spirit level on top of the machine. Adjust the four leveling feet at the bottom until all four corners are even.
-
If the washer was recently installed or moved, check for transport bolts.
Transport bolts are large blue or red bolts in the back panel. They must be removed before operating the machine. Check your manual for their location.
-
Plug the washer back in and run an empty rinse and spin cycle.
Watch and listen. If the drum spins without the 8C error, the reset worked.
-
If 8C returns immediately, stop using the washer and call a technician.
Continuing to run the washer with a faulty MEMS sensor can cause further damage to the motor and drum assembly.
When to Call a Professional
The 8C error is a critical fault that usually requires a technician. The MEMS sensor is a precision internal component — not a DIY repair. Contact Samsung support at 1-800-726-7864 or schedule a service visit. Expect repair costs of $200–$400 depending on the part and labor in your area.
Frequently Asked Questions
What is a MEMS sensor in a washing machine?
MEMS stands for Micro-Electro-Mechanical System. It is a tiny sensor that detects how the drum is moving and vibrating. Samsung uses it to balance the load and prevent the machine from shaking excessively. If the sensor fails, the washer cannot safely control spin speed.
Can I still use my washer with the 8C error?
No — you should stop using it until it is repaired. The MEMS sensor controls spin balance and vibration safety. Running the washer without this sensor working correctly can damage the drum, bearings, and motor. Stop and call for service.
How much does it cost to repair the 8C error?
If only the MEMS sensor needs replacement, expect $150–$250. If the control board is involved, costs can reach $300–$450. Always get a written quote before authorizing repair. On older machines, weigh the repair cost against a new washer.
