Typically, Samsung provides a limited warranty on parts and labour, often extending to the direct drive motor for a longer period (e.g., 10 years). Review your purchase documentation or the Samsung Canada website for specific warranty details.
Use a bubble level to check the top of the washing machine. Adjust the front and rear feet by rotating them until the bubble is centered. Tighten the lock nuts on the feet to prevent them from moving.
Service manuals are typically available to qualified technicians. Contact Samsung Canada's authorized service providers or search online technical forums specializing in appliance repair. Some parts distributors may also offer access to service documentation.
If the 'UB' error persists even with a balanced load, try reducing the spin speed setting to the lowest available option. This may temporarily mitigate the noise while you troubleshoot the underlying cause. Check for proper functioning of drain pump, as residual water can contribute to imbalance.
Loud thumping noise originating from the washer during the spin cycle. Observe error code 'UB' (Unbalanced Load) displayed on the front panel LED and reported within the Samsung SmartThings app. High vibration levels felt on the washing machine's chassis. Irregular drum rotation observed during visual inspection through the door.
Always disconnect power to the washing machine at the circuit breaker before performing any repairs. Do not attempt repairs involving high-voltage components unless you are a qualified technician. Improper repairs can result in electric shock or fire. Verify ground connection integrity before restoring power. Ensure the water supply is shut off before disconnecting any plumbing connections.
The Samsung Bespoke AI Washer employs a direct-drive inverter motor controlled by a variable frequency drive (VFD). The VFD regulates motor speed based on feedback from load sensors and an accelerometer. Imbalance detection triggers a reduction in spin speed or a complete stop to prevent damage. The unit communicates via Wi-Fi (2.4 GHz, IEEE 802.11 b/g/n) to the Samsung cloud for firmware updates (OTA) and remote control. The drum is suspended by dampening struts and springs to minimize vibration. Internal pressure sensor monitors water level.
