dishlex 100 model DX100WA get stop after filling water.

Water connection is from cold water inlet.
Knob is on economy
and on 'normal wash'.
Dishwasher gets start and fill water in 1.30 minutes from cold water inlet and then stop.
Kitchen sink mixer is been replaced.
Now water connection is given from cold water, before i am not sure, our mixer was quite old and water connection was given just before the water tape and do not know hot/cold connection, but now it is from cold.
After repair it is not working, stop after about 1.30 minutes after filling water.
Please advise.
