Have a GE dishwasher(2 years old) that originally gave me the "H2O" error code, but suddenly corrected itself, but is now not filling. Have replaced the intake water valve. Resistance on the drain pump is 17Kohms. When dishwasher is started it will fill only if I briefly pinch the injector hose between the intake water valve and the dishwasher (funnel/gasket assembly). Any ideas what the problem could be? It's seems like a pressure issue between the valve and the dishwasher itself. There are NO leaks anywhere. Once the dishwasher is running it seems to be fine. thx !
