Sorry for the delay do you still need help on this?
If so can you post the model number please.
Ok when you set it going what actually happens?
Can you hear the pump running?
Does it stop and then put water into it?
If you open the door when it stops is there water inside?
Ok if you look inside the dishwasher is there any water in there?
Is this a new install of the dishwasher?
Ok if its just been installed im taking it the water has been turned on?
If you the you need to pull the dishwasher out and check the fill hose hasn't kinked up at the back. As sometimes when you pushes this under the unit it can squash the fill hose and stop it from filling up with water.
Then retry it and see if it fills with water and let me know what happens.
Im afraid the hoses are at the back of the dishwasher itself.
But if its located next to a sink then look in the cupboards next to it and you will see the hoses. One may be attached to the sink and the other to the water supply with a small plastic tap on it. Make sure that tap is turned on. It should be I the 12 oclock position. If its in 3 oclock then the water is turned off.
But if the water is turned on then im afraid the water pipes are all at the back which mean the dishwasher will need to be pulled out sorry.
