Every time I use the washing machine the toilet and bathtub fills with water, i had my septic tank pumped 4 months ago, it just started doing this a couple days ago. when the washer is draining, my master bathroom sink/toilet make a gurgling sound. also last night i ran the dishwasher adn the water drained into my kitchen sink. i have 2 other bathrooms and they are working fine

You have a blockage or at least a partial blockage in the drain line that serves the kitchen and bathroom and laundry. Pull the toilet and snake the line.
