Hi,

If the water pressure at the kitchen sink is low will this affect the function of a dishwasher? My dishwasher goes through all of the cycles but it doesn't seem to fill up with enough water and also the washer cycle doesn't work. Could this be a result of the low water pressure?

Well once the washer is filled up it does not use anymore water from the faucet until it drains so that would not affect the washing cycle from not working.

Even with low pressure the washer will evetually fill. They should not start on their own until they have filled to the manufacturers preset level. You said "dishwasher goes through all of the cycles" and "washer cycle doesn't work" This sounds like a contradiction. Can you explain further?
