Our dishwasher is 1.25 years old and already not working (grrr!). When it is turned on, the lights cycle through like a normal wash cycle, but the motor isn't engaged nor does any water cycle through. This happened about a month ago and I took everything apart to make sure all of the connections were secure and it started working again...not this time. Any ideas?

Also, the dishwasher is connected to a light switch...which I find very odd, but it's been helpful in keeping my 18 month old's fingers from starting the dishwasher every 10 minutes! Could this have caused the problem? Is it okay to turn on and off the dishwasher in this fashion?

Thanks in advance for your help!

I have exactly same problem. Did you find out what went wrong and fix the dishwasher?

After long research, I found it could be one of these three:
1. Control board - this will be expensive part.
2. Inlet valve
3. Floating switch

In order to find out which went wrong I will get multimeter for test. Hopefully it is not control board....
