How to Fix Error OC — Step by Step

  1. 1

    Reset the Dishwasher

    Start by resetting the dishwasher. Unplug the power cord from the outlet, wait for 30 seconds, and then plug it back in. This will reset the control board and may clear the error code. Check the display to see if the error code is still present.

    💡 Pro Tip: If the error code returns after a reset, it's likely a hardware issue.

  2. 2

    Check the Water Level Sensor

    The water level sensor is responsible for detecting the water level in the tub. If it's faulty, it can cause the OC error. Locate the sensor, usually found at the bottom of the tub, and check for any signs of damage or corrosion. Use a multimeter to test the sensor's resistance, which should be around 1-2 kΩ. If the reading is significantly different, the sensor may be faulty.

    💡 Pro Tip: Make sure to consult the user manual or a repair guide for the exact location of the water level sensor on your specific model.

  3. 3

    Inspect the Drain Hose

    A clogged or kinked drain hose can cause the dishwasher to overflow, leading to the OC error. Check the drain hose for any blockages or kinks and ensure it's properly connected to the dishwasher and the sink drain. Use a plumbing snake or a drain cleaner to clear any blockages.

    💡 Pro Tip: Regularly cleaning the drain hose can help prevent clogs and reduce the risk of the OC error.

  4. 4

    Check the Float Switch

    The float switch is responsible for detecting the water level in the tub and triggering the drain cycle. If it's stuck or faulty, it can cause the OC error. Locate the float switch, usually found near the water level sensor, and check for any signs of damage or corrosion. Use a multimeter to test the switch's continuity, which should be around 0 Ω when the switch is closed.

    💡 Pro Tip: If the float switch is faulty, it may need to be replaced. Consult the user manual or a repair guide for the correct replacement procedure.

  5. 5

    Check the Control Board

    The control board is the brain of the dishwasher, and a faulty board can cause a range of issues, including the OC error. Check the board for any signs of damage or corrosion and ensure all connections are secure. Use a multimeter to test the board's voltage, which should be around 12V DC.

    💡 Pro Tip: If the control board is faulty, it may need to be replaced. This is a more complex repair and may require professional assistance.

When to Call a Professional

If you're not comfortable with DIY repairs or if the error code persists after trying the above steps, it's recommended to call a professional. Additionally, if you notice any signs of water damage or electrical issues, it's essential to seek professional help to avoid further problems.
