Error Codes for a Samsung Dishwasher

When an error code pops up on your dishwasher's display, it doesn't always mean it's time to go into panic mode. The code's intention is to help the customer troubleshoot a fault with the dishwasher without having to call an expensive repairman and/or go very long without the convenience of a dishwasher. Many of the common error codes that cause a dishwasher to stop in its tracks can be diagnosed and repaired yourself.

Error Codes for a Samsung Dishwasher

Common Codes

Unless it's complicated, most error codes have simple remedies. The following error codes require a restart to get the machine back up and running smoothly.

bE2 is a button key error that's causing the machine to be confused. Check that all buttons are free and clear and haven't been inadvertently mashed down for more than 30 seconds.

3E or AE is the dishwasher saying it needs a reboot. Turn off the machine and then turn it back on, and it should be ready to wash and rinse without delay.

PE is a problem with the motor being out of sync. It may not be serious and require just a restart.

More Serious Codes

There are some codes that should get your attention. For these, you'll want to do a little more investigating to find the root of the problem. You may need to move or unplug the machine to get it to reset and remove the error code.

4E means you may have a water supply valve that's clogged or closed.

4E1 is a sensor saying the water isn't at its ideal hot temperature to clean the dishes thoroughly.

5E is your dishwasher's attempt to alert you that the drain hose may be folded in on itself or is clogged. If you've recently moved the dishwasher or it had some significant vibrations during its last cycle, this could lead to a crimp in the line.

When to Call a Professional

There are a few times you'll need to unplug the machine for safety reasons or so as not to damage the machine by continuing to run it.

HE, HE1, tE and 1E codes refer to heating and water level errors that can cause damage to the machine, your flooring or dishes. The HE and HE1 are heating issues, while the tE is a problem with the temperature sensor and 1E is reporting a low water level that can damage the entire machine.

LE and OE point to water leaks. Before you have a deluge in your space, turn off the dishwasher and remove the plug from the socket. Close the water supply valve and call the service center or a trusted handyman who can work on Samsung appliances with confidence.
