@csaab ,
What is the model number of the dishwasher?
Have you checked that the spray arms are moving or have moved?
Try placing both spray arms in a position that you remember and then turn on the dishwasher. After it has filled and started to "wash" open the door and check the position of the spray arms.
It is the water pressure from the circulation pump that causes the arms to rotate, dispensing water.
If they haven't moved then you need to check if power is getting to the circulation pump or if both spray arms dispensing holes are all blocked which would seem unusual. If only the top spray arm hasn't moved then it may be a blocked pipe from the circulation pump to the spray arm as usually the lower spray arm is connected nearly at the pump housing
Since you have changed the pump and the control panel but not the control board first try using an Ohmmeter to check the continuity of the pump power supply wires from the control board to the pump. Do this with the power totally disconnected from the dishwasher.
If you know how to safely test for lethal voltages you could use a Voltmeter and check that voltage is being applied to the pump when it is in the wash cycle. Depending on your location it could either be 120V AC or 240V AC
