not enough water in dishwasher
I have a Kitchenaid dishwasher and lately the dishes have not been getting clean. I had a repairman out and found that there wasn't enough water getting into the dishwasher during filling (timed fill). He said he could not find a reason within the dishwasher and said he thought our water pressure was not sufficient. For some reason while he was here our pressure did seem to be slightly low (throughout the house). (Of course since then the pressure seems to be fine!). He recommended we have a plumber come out.
I am a little hesitant to call a plumber now since the pressure seems fine. I still have dirty dishes. Is there anything a plumber can do to check or help the water pressure to the dishwasher? What should I do?
Thank you in advance for any help.
