Possible causes:

• Faulty water inlet valve: 
  • Similar to individual codes, a malfunctioning valve could stay open and continuously fill the tub, leading to overflow while potentially impacting water level/pressure.
• High water pressure: 
  • Unusually high water pressure could overwhelm the machine's ability to regulate flow and cause an overflow, affecting both water level and pressure readings.
• Blocked drain hose: 
  • While primarily associated with drainage issues, a blockage can prevent water from exiting the tub properly, leading to overflow if the inlet valve keeps filling, contributing to both excessive water and possibly affecting pressure.
• Faulty water level sensor: 
  • A malfunctioning sensor might misinterpret the actual water level, allowing the machine to keep filling even when full, causing overflow and potentially inaccurate water level readings.
• Faulty pressure sensor: 
  • A malfunctioning pressure sensor might not accurately detect water pressure within the tub, potentially causing issues with both overflow and inaccurate pressure readings.
• Internal leaks or faulty components: 
  • In rare cases, internal leaks or faulty components within the machine could be causing both the overflow and water level/pressure issues.

Troubleshooting the 1 OC Samsung Washing Machine Error Code

1. Turn off and unplug the washing machine immediately: 
   1. Safety first! Prevent further water damage and ensure your safety.
2. Check the water supply: 
   • Turn off the water supply to the machine at the source (usually a valve behind the machine).
3. Disconnect the inlet hoses: 
   • Disconnect the hot and cold water inlet hoses from the back of the machine and check for any visible leaks or damage.
4. Inspect the drain hose: 
   • Disconnect the drain hose from the drain and check for blockages or kinks. Remove any debris you find and straighten the hose if necessary.
5. Consult your user manual: 
   • Your manual might have specific instructions for troubleshooting the 1 OC error code for your particular model. It might also offer guidance on checking the water inlet valve, water level sensor, and pressure sensor.
6. Reset the machine: 
   • Sometimes, a simple reset can resolve temporary glitches. Turn off the machine, unplug it for a few minutes, and then plug it back in and restart the washing cycle.
7. Contact Samsung support: 
   • If the above steps don't resolve the issue, contact Samsung support for further assistance or technician recommendations. They can help diagnose the problem based on your model and provide specific guidance, possibly including checking the pressure sensor and internal components if necessary.

Additional tips:

• Avoid overloading the washing machine, as this can put extra strain on the water supply system and potentially contribute to an overflow.
• Use the appropriate amount of detergent, as excessive suds can interfere with the water level and pressure sensor readings.
• Regularly clean the drain filter to prevent blockages that could contribute to drainage issues and indirectly lead to overflows.
• Don't attempt to disassemble or repair the washing machine yourself unless you have the necessary expertise, especially when dealing with electrical components like the water inlet valve or pressure sensor.

Remember, the exact cause and troubleshooting steps might vary depending on your specific Samsung washing machine model. Consulting your user manual or contacting Samsung support can provide the most accurate information and guidance for your situation.

I hope this explanation helps you understand the 1 OC error code and resolve the overflow and water level/pressure issues with your Samsung washing machine!
