Initially the control lock and cancel button were lit and the machine drained constantly. I turned the power off and back on again and now none of the buttons work and the cancel button illuminates and the machine try's to drain for 20 seconds and turns off and then repeats this cycle constantly...

You call a repairman or the manufacturer

Here is how others have solved the problem, by resetting the control panel.
