I have ordered and received a new gasket. I installed it but the water is still pouring out. I notice that two sides of the gasket are puffy and the other two sides have ridges. Which sice should I place into the groove. Also, it seems that only the ridged side will fit into the tiny opening at the bottom of the grove. Is it possible that I pushed the gasket in too tight since it is still leaking, or could it be a completely different problem. The customer service at AppliancePartsPros is wonderful.
I do not know which gasket you are referring to so I am not sure I can help.
Also it often makes installation of gaskets go a lot easier if you give them a very light coating of plumbers or white lithium grease.
Perhaps the following will be useful.

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.
