Using instructions I obtained over the internet, I first removed the DW's bottom cover panels so I could look inside the DW (with a flashlight) while it was running. I had to put their dishwasher through several wash cycles before I could pinpoint the location of the leak. (The water appeared to be coming from above on the left side of the DW, near the top, rear of the DW's blue "Pressure Chamber." Thinking that the problem likely lay in either a malfunctioning Pressure Chamber or in a malfunctioning Water Inlet Valve (after I had placed my parts order with APP, an APP tech informed me that the problem most likely involved a malfunctioning water inlet valve, I first decided to replace the valve, because that did not require pulling the DW out from underneath the counter (something I would have had to do to replace the Pressure Chamber). I was aided while replacing the water inlet valve by the video I found on the APP website instructing the end-user on how to replace the valve. The video was especially helpful in determining the proper connections for the wires supplying power to the valve--seeing that the solenoid on the new valve is located 90 degrees counter-clockwise from where it had been positioned on the old valve. After re-connecting everything, the DW experienced a slow water leak from both ends of the elbow-shaped brass connector that connects the Water Inlet Valve to the water supply line. I could not stop the leak with Teflon tape; however, pipe dope applied to the threads of the "male" fittings on the brass connector did the trick and stopped the leak. The DW is now working normally without any water leaks. I will hold onto the Pressure Chamber piece, in case this part malfunctions or breaks at some point in the future.
