    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.

    The water level 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.

  3. 3

    Measure the water level sensor Resistance

    Use a multimeter to measure the resistance of the water level 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.

    Replace the water level sensor (if necessary)

    If the water level 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.

When to Call a Professional

Also, 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.

Field note: PE is a no-fill / slow-fill complaint. The first test is household water, not a valve coil. On Samsung Dishwashers: fully open both taps, unkink the hoses, clean the inlet screens. A clogged screen or a saddle valve that cannot keep up trips this before the inlet valve itself fails.

What this code is not

  • Not a drain-pump failure.
  • Not solved by a new dispenser if both inlet screens are packed with mineral grit.
  • If the house supply is weak, the valve is innocent.

Common Causes

  • Faulty water level sensor: The water level sensor can fail due to wear and tear, corrosion, or electrical issues.
  • Water level sensor issues: The water level sensor can become clogged with debris or blocked by food particles, preventing it from working correctly.
  • Electrical issues: Loose or corroded electrical connections can cause the water level sensor or water level sensor to malfunction.
  • Blockages or debris: Food particles, detergent residue, or other debris can accumulate in the sensor or surrounding area, preventing the sensor from working correctly.
  • Software issues: In some cases, a software glitch or outdated firmware can cause the error code PE.
