It is so so easy! First of all use a turkey baster to draw out ALL the water from the base of the dishwasher. Then close the door, open it and as soon as you turn your power switch on press the 'P' for programme button on and off 4 times within 3 seconds.
If you are right handed, then use your left hand to press the power button on and your right one to rapidly press the programme button. Then put the power button off for 20 seconds, turn it on,turn it off wait 20 seconds and then turn on. Presto your problem is fixed!! Good luck
