How to fix leaking washing machine drain pipe?

[Nila1]

Hi everyone, 

Our washing machine got delivered and installed yesterday. When I put in a load, the drain pipe leaks and the opening below has a lot of water leaking from it. When I connect it to the bottom, water leaks from the top one. I gave up and put the drain pipe into the sink but water is still leaking from the bottom opening. I duct taped the bottom and it looks okay. Is there a way to close it properly as the duct taped would come off after a few loads? Thank you so much.
