If your dishwasher starts displaying some codes, it means there is a problem. Here is a list of different codes and solutions for these error codes. You can fix these issues on your own so that your dishwasher will be able to run again.

Pump Operation Error

If a 3C error code starts showing up on your dishwasher, it indicates that the pump is no longer working and that you should contact Samsung Support.

High-Temperature Water Supply Error

If your dishwasher has a 3E error code, the water is too hot. You need to check the water temperature and make sure that it is below 176 degrees Fahrenheit. If it is still too hot, you will need to set it to a lower temperature.

Thermistor Error

The HE1 error means that the dishwasher is too hot or too cold. This might happen if the heat relay on the main power board is stuck or if the thermistor is defective and needs to be replaced.

Water Supply Error

If you see an error code of 4C and 4E, the water pressure or temperature is not correct and is not enough to run the dishwasher.

To fix this problem, follow these steps:

  • Make sure the water pressure and temperature are correct before you install your dishwasher. This will make sure your dishwasher runs properly.
  • If a flood safe is not compatible with your dishwasher, you should not use it.
  • Make sure the water supply is turned on before running the dishwasher.
  • Supply Line: You will need to purchase a supply line from a plumbing store in order to connect your dishwasher. The supply line should be 10ft long and made of stainless steel.
  • Water Temperature: The dishwasher needs to be between 120 and 149 degrees Fahrenheit in order to run correctly.
  • Water Pressure: You should make sure the pressure in your home is between 20 and 120 PSI. If it is below 20 PSI, the water supply valve might not work.
  • Elbow: You need a 90-degree elbow to connect the water line to the dishwasher. It doesn’t come with a dishwasher, but you can find it at a plumbing store or online. The size is ½ inch NPT on one side and 3/8 inches with compression fitting on the other side.

Clogged Filter Error

These two errors (1E and IE) occur on the Waterwall models of the Samsung dishwashers. It tells us that the water is not flowing from the filter. To resolve this problem, you have to clean the filter.

If you don’t know how to clean the filter, check your model number in the user manual and follow the instructions.

Drain Error

If you see errors 5C, SC, 5E, and SE, it means that your dishwasher is not draining water.

A number of things can cause this problem, but the most common reason is that your dishwasher drain hose is clogged.

Here are the troubleshooting steps:

  • Check to see if the drain connection at your sink is blocked.
  • Examine the drain hose carefully.
  • Test whether or not your dishwasher is connected to the sink water flow.
  • The connection should not be loose.

Water Reflector Error

If your dishwasher’s error code 7E appears, the reflector isn’t operating properly. These are two procedures for solving the problem. Remove a packing tap from the Waterwall reflector if your dishwasher is new or has just been unpacked.

As a result, the reflector will begin to function correctly. Examine whether the Waterwall reflector is installed in the correct position. If it isn’t, reposition it and make sure it is turned on correctly.

Low Water Level Error

Error 9E happens when the dishwasher does not have enough water. After opening your dishwasher, empty any dishes that have filled with water. Make sure the machine is level and all wires are securely connected.

Replace the water level sensor or wire harness if damaged.

Access Point Error

If your dishwasher generates the AP’s error code, it indicates that it is in Access Point Mode. This mode aids in connecting your equipment to your phone.

However, if you are not attempting to connect to mobile and eliminate this problem, turn off the machine and restart it.

Button Error

If your machine displays bE and 6E error codes, the Dishwasher panel will tell you that a button is stuck. It generally takes two steps to solve it. Disconnect the power cable from the dishwasher.

Check the area under the buttons for any debris that can cause a short. If you find any, remove it and reconnect the power cable to the dishwasher.

Communication Error

If your dishwasher displays a CE error code, the control panel is unable to communicate with the rest of the device. To fix this, switch off and restart the appliance again.

High-Temperature Heater Error

The codes IE, 1E, and HC appear on rotary models to notify you that the water in your dishwasher is boiling. These problems can be resolved with these steps.

Remove the power cord from your dishwasher for 30 seconds and then reconnect it. Empty the washer. Fill it with detergent in the required amount and run the usual cycle.

Heater Error

Errors HE and tE happen when the temperature inside the dishwasher is not detected correctly.

To fix this problem, follow these steps. Empty the dishwasher. Simply fill the detergent and run the normal cycle.

Leakage Error

LC and LE errors can start happening when the dishwasher leak sensor feels some moisture or when the reflector is blocked. Whenever these errors start showing, the dishwasher will automatically turn on and will not stop.

Over Level Water Error

When you see an OC, 0C, or oE error in the display, it implies that there is more water than required inside the dishwasher. It may be because of the draining problem.

Check the connection at the sink, which is where the dishwasher is connected. Check for a blockage in the drain hose. Leave the water running in the tub’s drain line. You must now clean out the tub’s drain and filter.

Zone Wash Error

PC Error happens when the zone wash function is not working correctly. To fix this, unplug the dishwasher from the power source and run the cycle again.

Half Load Connection Error

PE error means the zone wash function is not working correctly. Remove the contents of the dishwasher. Fill it with detergent and run a half cycle.
