⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: DU Difficulty: Easy
Problem: Lid cannot unlock, possibly due to an obstruction on top of the appliance.
How to Fix DU Error (Step-by-Step)
- First, press the ‘Cancel’ button to terminate any running cycle, which may be keeping the door locked.
- Check the countertop above the dishwasher to ensure no items, like a cutting board or dish towel, are hanging over the edge and physically blocking the door from opening.
- Inspect the area around the dishwasher on the floor for any items, such as kitchen mats or fallen utensils, that could be obstructing the bottom of the door.
- Gently try to push the door fully closed to ensure it is properly latched, then try to pull the handle to open it again.
- If the door will not open, go to your home’s circuit breaker panel and turn off the power to the dishwasher.
- Leave the power off for at least 5 minutes to allow the dishwasher’s internal computer to reset.
- Turn the power back on and attempt to open the door. The reset should have released the locking mechanism.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
