How to Fix Samsung Dishwasher PE Error Code: Troubleshooting Guide

The error code PE on your Samsung dishwasher indicates that it has detected a low water level. This can happen even after the water supply resumes. There are a few potential causes for this issue. First, the low level sensor might be defective, or there could be a loose connection with the sensor wires. Another possibility is that there’s a fault with the main control board. To start troubleshooting, check for any foreign material that might be obstructing the floater of the low level sensor. It’s also important to examine the voltage between the pink and brown wires of the micro switch. When the dishwasher is operating normally, you should check the micro switch itself. Make sure to disconnect the connectors before doing this. If you lift the lever, it should show a short circuit, and if you lower it, it should be open. If you find that the sensor is faulty or there’s debris in the floater, you’ll need to replace the low level sensor or clean it out. However, if everything seems normal with the sensor, then the issue might lie with the main control board, which would require replacement. If you’re not comfortable performing these checks or repairs yourself, it’s best to reach out to an authorized Samsung service center for assistance.
