I have water flowing into the base tripping the flood switch which forces the dishwasher to go into drain mode.
I found the source of water to the vent hole on the "Water Inlet System" housing which is located between the Valvue Switch and the Pressure Chamber housing.
I’v checked for any buildup of debrie but all is clean. I’ve checked the two mico switches and they are fine and worked ok during the self test.
It appears to be a flow control issue but I have conflicting advise from other sources. One says it is the Valve switch which acts as an open/close door but also as a regultor. The service manual says it is the Pressure Chamber module that adjusts for water pressure, however, I think it only relates to water in the tank, not actual water pressure from the street.
Which one would you try first?
