I have a Whirlpool Duet model # GHW9300PW4 washing machine. It is leaking from the inlet nozzel (into the detergent dispenser cavity after the cycle completes and the unit is off. The leaking stops if I shut off the hot and cold water lines at the back (obviously) but I was curious if water temperature made a difference, and at this point, it does seems to...When I turned the cold line back on, no leaks (at least too slow to notice visually watching for several seconds), but when I turn the cold off and hot on, it immediately begins leaking through the nozzle again. Do you know where I can obtain a repair manual (I have the parts list from Whirlpool 800 number) and can you think of possible problem/solution please? Thanks much!
