Whirlpool Duet washing machines and dryers are designed to match each and offer superior quality cleaning features. Your Duet washer normally locks its door when there is water in the drum or the laundry is spinning. Troubleshooting a problem that keeps the door locked and your clothes trapped inside the washer involves checking the pipes at the back of the appliance, canceling the current cycle and checking the LCD display.
Cancel the Cycle
Press the "Pause/Cancel" button twice to cancel the current cycle then press "Drain/Spin." The washing machine will drain the water and unlock the door after a few minutes. An error, during the cycle, could be keeping the door locked.
Unplug the Appliance
Cancel the wash cycle, as outlined in Step 1, then disconnect the washing machine from its power supply. Wait a few minutes before plugging the washer back in and re-starting the cycle. This process resets the internal computer.
Check for an Error Code
Look for a code beginning with the letter "F" or the word "SUDS" on the LCD display. F codes indicate an internal electrical problem with the washer -- performing Step 1 helps resolve many of these issues without the need for repair. "SUDS" indicates an excessive amount of suds in the drum. The washer will wait until the soap dissipates so use less soap in the future.
Look for Blockages
Check the drainage hose at the back of the washing machine for kinks or twists. The machine might be unable to drain properly, causing the door to stay locked. The drainage hose should be no more than 96 inches above the floor if your Duet appliances are stacked.
