How to Fix Error PE — 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 Half-load Sensor

    The half-load sensor is usually located at the bottom of the dishwasher tub. Use a Phillips #2 screwdriver to remove the screw holding the sensor in place. Gently pull the sensor out and inspect it for any debris or blockages. Use a soft brush to clean the sensor and surrounding area.

    💡 Pro Tip: Make sure to check the sensor's electrical connections for any signs of corrosion or damage.

  3. 3

    Measure the Half-load Sensor Resistance

    Use a multimeter to measure the resistance of the half-load sensor. A good sensor should have a resistance of around 1-2 kΩ. If the reading is significantly higher or lower, the sensor may be faulty. Compare your reading to the manufacturer's specifications.

    💡 Pro Tip: Consult the user manual or manufacturer's website for the correct resistance value for your specific model.

  4. 4

    Check the Water Level Sensor

    The water level sensor is usually located near the half-load sensor. Use a T20 Torx screwdriver to remove the screw holding the sensor in place. Inspect the sensor for any debris or blockages. Clean the sensor and surrounding area with a soft brush.

    💡 Pro Tip: Make sure to check the sensor's electrical connections for any signs of corrosion or damage.

  5. 5

    Replace the Half-load Sensor (if necessary)

    If the half-load sensor is faulty, you may need to replace it. Purchase a replacement sensor from the manufacturer or a reputable supplier. Use a Phillips #2 screwdriver to remove the screw holding the old sensor in place. Gently pull the old sensor out and replace it with the new one. Secure the new sensor with the screw.

    💡 Pro Tip: Make sure to follow the manufacturer's instructions for replacing the sensor.

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 appliance technician. Additionally, if you notice any signs of water damage, electrical issues, or unusual noises, it's best to seek professional help to avoid any further damage or safety risks.
