Whirlpool ADP 4305 Not Draining

I have been using ADP 4305 for two years without problem until yesterday.
The Machine suddenly stop during the middle of the cycle and the start lamp blinking countinously.
When I opened the door there is water (about 2 cm) on the floor. After I drained the water manually (by hand) and restart the the cyle (by pressing start for 2 second), It will start working again for around 10-15 minutes and again stop working with the start lamp blinking continously. I have cleaned the filter but still no luck. Anybody know how to solve this problem.
thanks

When the start light is flashing, count the flashes between pauses and post the result here.

Thanks Sleppyhead for your reply. After turning it on again, it completes the cycles without any problem. So it was a false alarm. Sorry for the inconviniences.

No problem. If it happens again, check the start light, count the number of flashes between pauses and let us know.
