Samsung VRT Washer Error Codes: UB, DC, 4C, 5C, LE Guide

Quick Answer

Samsung VRT (Vibration Reduction Technology) washers include both front-load and top-load models with the VRT anti-vibration system. VRT-specific behavior: the VRT system uses sensors and counterweights to reduce spin vibration. When VRT detects excessive imbalance, it reduces spin speed or stops the spin cycle entirely - this is by design, not a fault.

Samsung VRT (Vibration Reduction Technology) washers include both front-load and top-load models with the VRT anti-vibration system. VRT-specific behavior: the VRT system uses sensors and counterweights to reduce spin vibration. When VRT detects excessive imbalance, it reduces spin speed or stops the spin cycle entirely - this is by design, not a fault. However, it means clothes may come out wetter than expected. The UB/UE code on VRT washers means the vibration exceeded what the VRT system can compensate for. Common VRT codes: UB/UE = unbalanced (redistribute load), DC = door check (front-load door not locked), 4C = water supply (check valves), 5C/5E = drain error (clean pump filter), LE = water leak detected (check door boot and connections). Samsung VRT diagnostic mode: hold Delay End + Soil Level simultaneously for 3 seconds.

Frequently Asked Questions

How do I find my model number?
Check the inside of the door (front-load), inside the lid (top-load), or the back/side panel for a sticker with the model and serial number.
Is it worth repairing?
If the appliance is under 8 years old and repair is under 50% of replacement cost, repair is worthwhile. Check warranty coverage first.
Can I fix this myself?
Many repairs are DIY-friendly with basic tools. Gas appliances and sealed refrigerant systems should be serviced by professionals.
