What Does Error UC Mean?
The Samsung Washing Machine UC error code indicates an unbalanced load condition, often resulting in excessive vibrations or shaking during the spin cycle. This can occur due to unstable mains voltage or faulty electrical connections. Power supply irregularities may cause the washer's control system to halt operation, displaying the UC code either during the start of the cycle or mid-cycle.
Common Symptoms:
- Error code UC appears on display during or right after start of cycle
- Machine may stop mid‑cycle with UC code
- Occurs even when water fill or spinning begins
Possible Causes
- Unstable mains voltage (overvoltage or undervoltage) (medium)
- Loose or faulty electrical connection (socket, cord, plug) (medium)
How to Fix Error UC
DIY Fix Check electrical supply and reset
- Turn off and unplug the washing machine from the outlet
- Inspect the power cord, plug, and wall socket for visible damage
- Wait a few minutes, then plug back in and restart a wash cycle
- If available, try a different dedicated outlet
Technician Only Inspect and stabilize power supply / internal wiring
- Measure mains voltage at the outlet under load to confirm stability
- Check internal wiring connections and grounding at the machine
- Test and, if necessary, replace the voltage sensing/control board
- Recommend installation of a voltage stabilizer or dedicated circuit if home supply fluctuates
Parts needed: Multimeter for voltage testing, Control board or voltage sensing module (if faulty)
- Error persists after checking/replacing outlet and cord
- Voltage at home supply is unstable or out of normal range
- Internal electrical component failure suspected
