Water backs up into our kitchen sink every time the dishwasher goes into its drain cycle. It's not a lot of water; it barely covers the bottom of the sink. The water doesn't back up until near the drain cycle and as soon as the drain cycle ends the water quickly does down the drain. It's done this for a couple of years. It hasn't gotten worse; it hasn't gotten better over that time. The p-trap isn't clogged. I did about two weeks of Bio-clean, but that had no effect.
Is there anything I could and/or should do about this?
Thanks.
