The dishwasher fills up with water, and will pump out the water, but no water is going to the spray nozzles. The compartment is just steaming up. What could be causing this?

Check water pump and make sure there is no bloks in the pipes try using a good dishwasher cleaner and if its got the turn bit on base inside open it and make sure filters are clean blessings

If your dishwasher has set off an alarming F06 error code on the digital display, it is likely to be a problem with the water filling the machine.
Check for an intermittant inlet solenoid.

try removing spray spinner and clean out holes the spray heads get blocked and stop water flow, or you may be able to remove spray nozzles and clean out , i had this several times in the past also make sure the base drain filter is clean some times the small holes in the filter get smaller and smaller reducing water flow
hope this is of some help good luck

Yes. The water pressure in the hydraulic system is very important.
If more water flows through the hydraulic circuit of the lower nozzle, then probably that the upper nozzle will not rotate which will cause poor wash results.

Heating element may fail. This will lead to the machine stopping part way through its cycle

Pumps. There are 2 pumps in most dishwashers. The drain pump,( which describes itself -it pumps the water out of the machine.)
The recirculating pump which forces the water at high pressure through the spray nozzles and arms. (This is how the cleaning action is performed)
These pump may either leak, or burn out. Either way, the only solution is replacement.

what makes the circulation in the dishwasher? the circulation pump. just check the water going in and the water going out.

Water pressure makes the arms move, so your pump must be defective

Either the pump is not able to pump due to clogged pump or there is not enough water in the tub after filling to get up to the upper spray arm.

Listen to see if you can hear pump run when pressing button, if the pump does run, than either you have a clogged nozzle or screen in water fill compartment.

it just means that the pump needs primed. Turn on at the wall and on the machine, wait until screen says ready (make sure water tank full), then turn steam handle on RHS to on (do not push the steam button). the pump will prime until water comes out of the steam nozzle. now turn off the steam handle and you are ready to go!
