Hi if the first light is flashing it is water getting on to the bottom tray. This is caused as the rins is set to high turn down to about 2 on the ajuster where you put your rins.
You then have to get rid of the water. Turn the dishwasher of and un-plug it. Pull out and tilt dishwasher back untill water stops coming out there will be about 1/2 a cup. Mop up and plug in ,every thing should be working ok again.
