This is a typical problem that occurs on average every 25 years in a house. There should be a stack that the laundry tub goes into that also might be connected with the kitchen sink from above. The average line is a 4 inch pipe and over time it plugs under the floor with lint and soap which turns into a very thick sludge. I do not advise to use any acids for if you have metal lines it could eat a hole thru the pipe. You could use some enzyme based drain cleaners. But your best bet is to call your local Roto-Rooter and have the line cleaned out.
The washing machine works by filling with water and rotating. The operator has to put in soap, bleach and softener. The washer agitates, then spins, then fills with water, then rinses by agitating, then drains again by spinning.
They share the same drain and it is becoming clogged. Drain cleaner in both drains should help.
It depends on what kind of washer you have! Normally the water will drain on it's own, though it takes time because the drain doesn't suck it in or anything - it just drains out on it's own; but it still depends on the type of washer you have. If there isn't a drain in the bottom then you'll probably have to scoop it out or something, which is probably some back-breaking work. Check if your washer has drains in the bottom.

There is a slight blockage somewhere in your waste drainage system
Storm sewer is crossed with the sanitary sewer or the washer drains into the storm sewer. Either way the storm sewer is likely blocked somewhere.
It goes into the main sewer system. It will go through your sewer system and then out to the main sewer. That is if you live in town!
Chances are there is no lint trap on your washer. Do you have a model and serial #?You have one on you "DRYER" but not your washer,i dont think.
There are multiple reasons why your washing machine might not drain. The drain line could be clogged with debris or even clothing, the pump pulley could be frozen, or the pipe that the washer drains into could be clogged.
Place a stocking on the end of the hose BUT Check it after each wash.
Essentially it contains a screw (under the handle) driving a round rubber washer onto the incoming pipe. This blocks the supply, but also slowly destroys the washer after a few years. At this point the washer can be easily replaced.
Partial blockage. Snake the drain.
