This sounds like it may be a blocked vent. A back surge that pushes air ahead of it should go up the vent and not the stand pipe. What size is your trap and stand pipe?
You say," The pipe is clear/no blockage.. " but something's changed to give you this problem that you have. New washer? Are you QUITE SURE the drain's clear?
Perhaps you should look a little closer at a washer surge pipe, (see image).
This goes along with what I've been advising all along. Sealing off the washer hose with a compression fitting,(see image) and forcing the pump to push the water out into the main. If both the drain and the vent's clear,( How do you know for sure?)then you have two options open. You may seal off the washer hose making it a closed circuit or you can build a washer surge pipe. Let me say right now that if the drain pipe's blocked the only thing that will solve the problem is to snake and clear the drain line. Let me know what you decide. Good luck, Tom
