Dishwasher not resetting before new cycle

It look like you have a cold water supply problem- check water entrance pipe, myaybe it was bend (if you have there a tap - see it is open).
Check that water entrance valve work (it is an electromagnet valve,loocated at the pipe's enterance to the machine).
If it doesn't work, test that it get power. In case it get power and dosen't work - You can easyly open the valve and clean it (from scale or other dirt). Be aware you should disconnect the power cable from machine before doing it !!!!!
Check as well for valve's coil resistance. In case you have no resistance measurement - you should replace for a new valve.

I have had the same problem. The issue is with the dip tray + overflow detector under the machine. What happened is the dip tray is full of water and the overflow detects this condition and prevents the machine from starting.
It looks like there is no water present in the machine but the drip tray, located underneath, is full. Give the machine a good shake and you should see water.
I solved it easily: just get a mop, lift the machine's front so that it tilts backwards and collect the water as it escapes the drip tray towards the back of the machine. The tray can collect quite a bit of water so you're likely to need a few tilts until it's empty.
In my case, the underlying case had been a previous mistake - we didn't allow the machine to finish completely and water had remained on it. Somehow the water had found its way to the tray. Other causes my be another appliance sharing the same waste pipe and pushing water down the dishwasher's waste system.
