I am only posting to give my fix to above problem which will be useful to other people. Sometime people post the question but they do not get any reply and they call a plumber and get it fixed but they should always right there solution after the plumber had fixed it so that other people on the forum can get their problem fixed.
My circuit breaker had tripped so I knew something had gone wrong with the electrics.
After reading some other post as to how to fix this problem, first I disconnected the power cable of dishwasher from the socket. This is very important before you do anything.
I then took of both bottom black plastic covers and found 1 inch of water.
I removed the water with some towels and to dry it completely, I used electric room fan heater and within 10 minutes it was completely dry.
I then tried to start buy when I pressed power on all the program button including timer and half load all lighted up. After trying for few times, dishwasher started but all programs were still on.
However after switching on and off few times, the full normal program (120 minutes) has now started. I am waiting fo rit to finish and check whether it has now resumed normal operation and will report back.

Normal program finished without any problem after 120 minutes, with few usual beeps at the end.

No leaks and all water was drained normally.

Afterwards, I was also able to chose between different wash program, which I could not before.

Thanks to all who had posted about how to fix it by removing black plastic covers from bottom compartment, check for water and drying out water from the motor compartment.

Only thing I do not know is where the water came from in the bottom compartment?
