Sewer drain leaking into basement wall

[Justin Israelson]

Noticed wet floor and drywall along the floor where the abs sewer drain is. Followed it up and noticed mold and wetness where the pipe comes from the kitchen through the floor. It is directly behind the dishwasher. I’m assuming the pipe jogs from under the sink and comes down where the dishwasher is. Do I need to start cutting into the kitchen wall, or is there another explanation?

have you looked under your kitchen sink,remove the access plate under the door of the dishwasher there should be 2 screws with a flashlite look under there for signs of water it could be your water supply ,your drain connection,or your pump is leaking..could be your door gasket but I think you would see it
