What should you do if your Samsung washing machine stops spinning?

Make sure it's installed on a level solid surface, also make sure to adjust the feet, an uneven surface is one of the most common reasons for excessive noise or vibration.

Make sure to balance the load. Washing only one heavy item will cause excessive noise and vibration and could damage the washing machine.

Check for overloading, how much weight the washer can handle is based on its capacity. On many devices, you can find the maximum capacity of your washing machine on the control panel.

If the drum does not revolve at all during the wash and spin cycles, an engineer will be needed. To test this, perform a short cycle with no washing and no detergent. When the cycle begins, you must keep an eye on the drum. The device will fill with water within the first few minutes; after that, peek through the entrance to check whether you can see the drum turning. It is usual for it to restart and stop several times. If the drum still does not turn, you can get it repaired.

An ideal spin speed is established for each cycle. An automatic selection is made for this. In most cases, you can manually select a slower pace. On the majority of cycles, you are limited to the fixed speed.
Usually, only a cotton cycle or specialized spin cycle will let you choose a full spin speed. This will shield your clothing from harm from a spin phase that is too high for the fabric. For more details, please refer to the user manual.

The machine will not spin properly if the drum has stopped draining. Normally, a 5C check code will be displayed. If it is draining but at a sluggish rate, you may not notice a check code. Our tutorial on what the codes on my washing machine indicate contains a detailed explanation of these codes. It is also a good idea to clean the filter on a regular basis to keep it from becoming clogged.
