4. OBSTRUCTED OVERFILL PROTECTION FLOAT
To ensure proper filling, the overfill protection float must be in place in the dishwasher. On some models, it is located in the front right corner. If your dishwasher is a newer model, it’s recommended to have a professional inspect it.
To check the float, move it up and down to ensure it moves freely. Remove any obstructions, if necessary. See your owner’s manual for more information about locating and checking the float.
