I think our dishwasher has low water flow/pressure. it doesnt clean the dishes well at all. How do i tell if the low water flow is just the older model dishwasher or low water flow to the dishwasher in general? We are going to get a new one and want to know how to increase the water flow to the new modle if it needs it.

Typically the dishwasher water supply is located under the kitchen sink, so it has the same (should have the same) water pressure as the hot water to your sink. When you pull the old dishwasher out, put the end of the water hose in a bucket and see if you have good pressure.
The other thing is the diswasher has a pump in it so once it fills with water the pump pushes the water through. Old dishwashers have old pumps which can effect the water flow, or junk (food or plastic missed on plates) can plug up the water flow. Usually you can look in the manual and it will tell you what to look for .

For the most part, it is not the pressure of the water that cleans the dishes. It is the action of the surfactants, the heat, and the acids that clean the dishes.
The surfactants might be understood as lubricants. They make the unwanted materials "slip" off the dishes.
The heat of the hot water helps all the other processes along.
The acids are like bleach, ( in fact most brands use a dry form of sodium hypochloric acid, which IS the active ingredient in most laundry bleach ).
If you WERE to be able to radically increase the water pressure, you would break the glass, pottery, and plastic. You would bend the metals. And you would cause them all to end up in the bottom of the unit.
All that being said, you DO need enough pressure to get SOME flow across all the surfaces that are to be cleaned.
IF you already scrape off, and / or rinse off the majority of the foods from your dishes, AND stack them as directed in the dishwasher's owner's manual, ( so the silverware, and dishes ( etc. ) don't "nestle" together ), AND use the right quantity, and quantity of DISHWASHER "soap" ( such as "Cascade" ), AND a drying agent ( such as "Jet Dry" ), your dishes should come out clean, dry, and spot free.
On the other hand, if you just haphazardly throw your dishes in that still have food on them, they are NOT going to come clean, and your screens, filters, and pump is going to be plugged with said left over foods. You will need to get in there, and scoop the detritus out of there.
There IS one more possibility. If your unit is VERY old, and your water has a VERY large amount of semi suspended solids, such as calcium's, or limestone, etc., you may need to run a few chemicals through your system. ( Possibly a few times. ) There are chemicals specifically designed for this, both residential, and commercial strengths. These are basically just acids to be diluted in water that will re-emulsify the problem materials, and wash them down the drain.
If the pump runs, you have no leaks, and no electrical problems, you probably don't need a new dishwasher, just a new way of USING the one you have.

Low water pressure to the dishwasher will only take it longer to fill. The pressure that is used to clean the dishes is supplied by the pump. It is better to not waste time and money to repair if you are getting an new on any way. Pumps can cost any where from 75 to 150 dollars and then the cost of a service call and the time to install it.

Where the hose goes into the dishwasher..simply undo it and look for a screen either in the washer itself or the hose where it connects..or where the hose connects to the water supply..chances are that it is simply minerals in the water supply(which is common) have stopped up the screen..clean the screen off and reinstall..
