Not enough info.
Size of stand pipe, height of stand pipe, feeding into what size pipe.
Give us this info and picture if possible and we can help.
By adding a compression fitting and then washer hose u could make a closed system.

Vents do not repair backups. Chuck gave you the straight dope on what could cause your back up and a solution to fix it. If you have a 1 1/2" standpipe and drainage then Duct taping the hose into the stand pipe or installing a compression fitting,(see image) is the way to go. The reason for this is the today's washer pumps are much more powerful now. I had to make my own washer into a closed system because of backups. Good luck, Tom
