Samsung Dishwasher OC Code Error Fix

What is the OC Error Code?

The “OC” error code on a Samsung dishwasher typically indicates a problem with the overcurrent protection. This code is displayed when the dishwasher detects an issue with the water supply or drainage. A beeping sound accompanies the code. These were caused by various issues, such as a malfunctioning component or a problem with the dishwasher’s wiring. If the OC Error Code appears on your Samsung dishwasher, it is recommended that you unplug the dishwasher and check for any blockage in the drain hose and filter.

Why Does This Error Appear?

The OC Code Error can appear on Samsung Dishwashers when the dishwasher is having trouble draining water from the tub. Several things, such as an obstruction in the drain hose, a faulty drain pump, or a malfunctioning water level switch, can cause it. If the OC Code Error appears, it is important to troubleshoot and address the underlying problem.

Fix Samsung Dishwasher OC Code Error

Multiple reasons cause Samsung dishwasher OC Code errors, and some fixes are available to resolve this code error on the Samsung Dishwasher. However, you can easily fix this problem if you are one of them and facing a similar issue. Here are some basic methods to eliminate the OC code error on your dishwasher.

Fix 1: Check for Address Drain Issue 

The water issue on your Samsung dishwasher is connected to a drain problem. But you don’t need to worry, as drain issues are common and can easily be fixed by following some steps. To fix the Dishwasher OC Code error issue, it is important to check for any address drain issues. A clogged drain, a kinked drain hose, or a faulty drain pump could cause this. To check for a clogged drain, you can use a vacuum to remove any debris or obstructions.

To check for a kinked drain hose, disconnect it from the dishwasher and inspect it for any bends or kinks. If the hose is kinked, it should be replaced to ensure proper draining.

Fix 2: Clean the Drain Pump

The other cause is the drain pump in the dishwasher. Sometimes the dishwasher collects unnecessary particles of food or detergent, which cause this error. You will need to clean the drain pump to fix a Samsung Dishwasher OC Code error. First, unplug the dishwasher from the power source and turn off the water supply. Then, remove the lower panel of the dishwasher and locate the drain pump. You may need to use a screwdriver to loosen the screws and remove the pump.

Once you have access to the pump, remove any debris that may be clogging it, such as food particles or detergent. Once the pump is clear, reassemble the dishwasher and plug it back in. Finally, run a test cycle to ensure the OC Code error has been resolved.

Fix 3: Clean the Filter

The other reason that the OC Code appears on your dishwasher is the cause of the filter. However, you can clean the filter on your dishwasher to fix the error code issue. But before cleaning the filter, ensure there is less to no more water to ensure it won’t spill when opening the dishwasher door. 

  1. First, locate the filter at the bottom of the dishwasher. It should be in the center of the dishwasher, behind the lower spray arm.
  2. Unscrew the filter and remove it from the dishwasher.
  3. Clean the filter using a soft cloth and warm soapy water. Rinse the filter thoroughly and screw it back into the dishwasher.
  4. Make sure it is securely in place. After cleaning the filter, it should resolve the OC Code error.

Fix 4: Check for Sensor Issue

When a Samsung dishwasher shows an OC code error, it is important to check for any sensor issues that could be causing the problem. The sensor monitors the dishwasher’s water level and helps to regulate the temperature. If the sensor is faulty, it will cause the dishwasher to overfill and throw the OC code error.

To check the sensor, open up the dishwasher and access the internal components. Look for the water level sensor and check the connection to ensure it is secure and not damaged. If the sensor appears not in working order, it might be necessary to replace it. After replacing the sensor, be sure to test the dishwasher to make sure it functions properly.

Note: When you perform any solutions, reset your dishwasher machine. To reset, unplug the dishwasher machine from the power outlet and wait for a few minutes until it completely discharges. After a few minutes, you can plug it in again.

Common Dishwasher Error Codes

Compared to other dishwasher appliances, the modern version of the Samsung dishwasher has many features to save water, detergent, and more. Among these features, users can identify the problem when the dishwasher occurs by displaying an error code.

There are some common fault codes mentioned below to troubleshoot the common dishwasher error codes, as there are a few errors that are easy to deal with and can be easily fixed by performing some basic workarounds. In contrast, other fault error codes need help from Samsung experts.

Fix 1: 3E (High-Temperature Water Level Error)

Samsung dishwashers have some codes on the dishwasher control board, such as OC Code and 3E error codes. However, when the 3E code appears on the dishwasher, it means that there is excessive heat in the dishwasher. 

To solve the 3E code error on your dishwasher, adjust the temperature manually below 80 degrees Celsius or not high as 176°F. You should contact the Samsung Support Centre for further details if this fails to fix the error code.

Fix 2: 5C, 5E (Dishwasher Drain Error)

If your Samsung dishwasher is displaying the OC Code error, there are a few troubleshooting steps you can take to resolve the issue. 

5C Error Code: Check the drain hose for any kinks or bends that could restrict the water flow out of the dishwasher. Ensure the hose is properly connected to the sink and the water drains properly.

5E Error Code: Check the drain filter for any clogs. If the filter is clogged, it can be removed and cleaned with warm, soapy water. Be sure to rinse the filter thoroughly before reinstalling it in the dishwasher. Additionally, check the drain pump for any obstructions that could be preventing water from draining out of the dishwasher.

Fix 3: 1E, IE (Clogged Filter Error)

The 1E, IE fault error codes usually appear on the Waterwall model of Samsung dishwashers. However, when you see these codes on your dishwasher, you should clean the dishwasher filter (refer to the user manual), as these error codes indicate that the water is no longer flowing as the filter at the bottom is full of dirt. If the issue is not solved, contact the Customer Support team or visit the nearest Samsung Support Centre.
