Unhappy Need more water pressure to dishwasher

Our Frigidaire Pro Series D/W requires at least 20 psi to run. The washing arms in the "ceiling" of the tub and under the top rack do not spin or spray. First, how do I test the pressure in the hot water line going to the dishwasher? Second, is there any kind of small pump that could be installed, either at the pressure tank or further downstream, close to the dishwasher?
Any other ways to increase the pressure? We are on our own system (well). I make sure to avoid using any other water at the time the dishwasher is running, and there still is not enough pressure. The bottom washing arm works great, in fact, well enough to get to the top rack if I load it lightly!
Thanks for any help!

The hot water pressure is controlled by the cold water supply going into the water heater. This tells me that it is likely you have a blockage in the hot water line. Is the dishwasher supply hooked up with one of those instant tap type connectors (clamp on and screw in a piercing tip)? If so, thats the first place I would check. These also restrict the flow. Good luck.

Hi, I may be all wet but I thought dishwashers had thier own pump. Water comes in, at a certian level a float shuts off the seloined and the cycle begins. Check the water level inside the dish washer. shut it off durning a washing cycle and open the door if you have a lot of water in the washer maybe one of the arms are plugged.
Good Luck Woodbutcher

Thanks for the reponse, and you are right, the dishwasher does have it's own pump, but it's wimpy compared to the one we had in the previous dishwasher. We pulled the washer out from under the cabinet and ran it for a cycle, and everything appears to be okay, just not very powerful compared to others we have had.
Thanks again!
