  • Blocked water inlet valve;
  • Low-quality detergent or using too much of it;

How to solve the problem?

a lot of foam in the Samsung washing machine

Here is what you need to do to fix the situation and make your washing machine work normally:

  1. If there is a lot of detergent in the drum, it creates a lot of foam. It gets inside the pressure switch tube and forms increased pressure. Therefore, water level sensor starts the process of draining the water, and you see the code on the washing machine display. In this case, you need to drain the water, take out the laundry and start the rinse mode in order to wash the drum. Next, run the machine as usual to check to make sure that error OC is no longer there.
  2. If the washing machine is not properly connected to the drain hose, you will also see error OC on the display. You will be required to properly install the drainage to the sewer pipe.
  3. If there was a temporary failure in the control module, then here’s how to fix it – turn off the washer and let the machine rest for 5 minutes, then turn it on again, and start the washing cycle.
