I bought a house with a slab foundation that came with an efficiency under the counter washing machine. This machine came with a drain line has an attachment on it that connected under the counter to the drain pipe. I replaced that attachment by extending the drain line and created the stack line 39" off the frond. I tested the drain and failed because the drain is filling up and water comes out over the top of the stack. I think my mistake was using the same 1 1/2 " piping that was originally there. They had reduced to get that. I think my issue is not using 2". Any thoughts?

does picture #2 hook up to #1 with that clamp?

double trapped. thats part of the problem.

and yes, it needs to be 2'' ALL he way to the vent/san tee.

also. in picture #1 i see a dishwasher hose hooked to the disposal.

pick the hose up. tie it to the bottom of the cabinet, make a loop.

this will keep crap from backing into your dishwasher, causeing it to stink
 
I'm digressing into my 2nd childhood.

I think this is how you extended it. But should be 2" all they way to santee like FRODO said. can you eliminate the 90? If not try using 2 -1/8th bends or a longer radius 90
