You can find the following previous question and a lot more like it, with answers, in the Home > Plumbing link under Browse Projects, at lower left.

Your problem could be undersized piping, especially if you now have a new washer with high discharge capacity which is now causing that - many newer washers need a 2" drain line rather than the 1-1/2" in most houses more than a decade or so old. Obviously, if this is a new issue with same washer as before, that is not the case here.

Could also be that the washer and kitchen sink are on the same drain line branch leading to your main drain pipe stack (especially if washer is in or adjacent ot kitchen), and that line only has gotten lint or sink waste clogged and just needs snaking to clear it out - especially if this the only drain gurgling like that and there are other drains in the house at same or lower elevation which are NOT doing that when the washer empties.

But if this is a new problem with same washer, you have a partial blockage somewhere in the piping, or if the kitchen sink is the lowest or near lowest elevation drain in the house, could be your septic tank needs pumping or the leach field is plugging up and needs refurbishing. Look in the above-mentioned home > Plumbing category for a lot of previous questions on this symptom - and my recommendation on doing full-length full-diameter drain cleaning all the way to the septic tank if that has not been done in a while, rather than just snaking to clear the clog.

And of course if septic tank has not been emptied recently - say commonly in last 2-3 years with large family, 3-5 year intervals for say 4 person household, or 5-8 or so with 1-2 person household - with normal 400-500 gallon range septic tank. Of course, required interval depends a lot on tank size; and amount of garbage put down the drain or through garbage disposal, amount of grease put down the drain, and amount of antibiotic or disinfectant material put down the drain (all bad for the septic tank functioning).

Your Search the List category for someone to fix this - Plumber commonly for in-house drain line clogging, or Sewer and Drain Cleaning to clear the line all the way to the septic tank. Septic for septic tank pumping and leach field functioning test and.or refurbishing. More on that subject in the Home > Septic link under Browse Projects.
