I have lower about 1/3, water pressure in my kitchen sink and to my dishwasher. Nothing else in my house seems affected and a gauge confirms pressure to the house is 60psi. We took apart the valves under the sink and confirmed good water supply so we cleaned the screens and still not enough pressure. I can't even get more than a cup or so of water flow to run the dishwasher properly. Not sure what else it could be - any help appreciated.

Take off supplies from the angle stop and test-open water. See, how much pressure you have...

D/W has another filter right at the solenoid valve, where water supply connect/ under the D/W. Also, make sure the supply hose is not kinked.

Kitchen faucet may be clogged in the unit itself. If you have pull-out type of faucet, there are 2 additional flow restrictors: one in the house ( back flow valve ) and flow restrictor inside the handle. Of course, there is also aerator to be cleaned periodically.
