Whirlpool Dishwasher E1 error code

Difficulty: Easy · Cost: $0–$150 · Duration: 5–10m

The E1 error means your Whirlpool dishwasher's overfill protection float — located in the front right corner of the dishwasher tub — has detected that the water level is too high, or the float itself is stuck and not moving freely. The float must be in place and able to move freely for the dishwasher to operate. Check the float area for obstructions. A power reset sometimes resolves a stuck float sensor reading.

Common causes

  • The overfill protection float is stuck in the raised position due to debris around it
  • An object or piece of food debris is blocking the float from moving freely
  • The dishwasher may be siphoning water — drain hose installed too low
  • Water inlet valve is faulty allowing too much water to enter

How to fix it

  1. 1

    Open the dishwasher and locate the overfill float in the front right corner of the tub

  2. 2

    Remove any food debris or objects from around the float area

  3. 3

    Move the float up and down by hand to confirm it moves freely

  4. 4

    Unplug the dishwasher or turn off the circuit breaker for 1 minute then restore power

  5. 5

    If E1 persists contact a qualified technician or schedule service
