** I have a GE dishwasher and it is 4 years old. It runs but it does not spray water. What do I need to look at? **
The first thing which should likely be done is ensure it is filling with water properly (which should be in the area of just below the element). If it isn't filling, it won't be able to wash.
If you need further assistance, it would be a good idea to post the dishwasher's model number so we can see what parts it uses which might cause your symptoms. You can find tips for locating the model and serial number tag *on your appliances* in the 'Repair Parts' section of my site linked below.
