My whirlpool duet front loader stopped operating and the end of the spin cylcle with one minute left. Pressing the pause/cancel button would not release nor pressing the power button. Unplugged and tried to start again but the cycle would not start at all and the pause/cancel button still stayed locked

SOURCE: Control lock light will not go off.

Do you have any error codes?

Does water remain in the washer after the final spin?
If water remains in the washer after the final spin, then the door will not unlock. Drain/Spin or Spin Only to remove any remaining water from the washer. The door should unlock at the end of the cycle.
Is the door locked and the Add A Garment light on?
If the Add A Garment light is on, then the washer door will unlock after the Pause/Cancel button is pressed once. Pressing the Start button will restart the washer at the same point where it left off in the cycle.
Is the door locked and the Add A Garment light off?
If the Add A Garment light is off, then the washer door will unlock after the Pause/Cancel button is pressed twice. The door will not immediately unlock while the cycle is running due to a possible high-water level in the washer, high-water temperature, tumbling or spinning. It may take up to five minutes for the washer to stop spinning and draining before the door will unlock. You will hear the door click when it unlocks.
If Pause/Cancel does not work:

1. Unplug washer or disconnect power for one minute.
2. Plug in washer or reconnect power.
3. Re-select the cycle and press Start.

Press 'end of cycle' for over 3 seconds. Perhaps you have to check your filter, maybe clogged.

The filter on your pump is probably clogged with lint and stuff. You have to remove the bottom front panel, 3 torx screws underneath. The panel will drop and come off. Drain off the excess water from the drain pipe you see. The white filter cover is right in front. Get yourself a good plastic bag to collect water. Unscrew the filter cover and twist the filter out. Clean out all the stuff and put it back in carefully. Check your pump too, comes after the filter.
