It sounds like you need to re programme the
machine.
With the machine plugged into the wall and
turned on and the headset turned off this is what
you do.
Push and hold down the start button, while doing that you need to then push and hold down the power button.
Hold them down for about 5 seconds, during
which time you may a series of up to 3 beeps.
Then release the buttons.
Turn the machine off and then on again followed by the start button. Allow the machine to then run the complete cycle.

Try unplugging the washer to reboot the computer board. Sometime power surges at night can cause undervoltage on the board and make it do funny things. Rebooting by removing power for 10 min will drain the board and start with a fresh program. This is true for microwaves, dishwashers, dryers, etc.....
