Improper venting.
It might be plumbed wrong -- or either your sewer is stoping up --
Sounds like the washing machine discharge is fitted to the main drain in the wrong place and it's discharge is filling your toilet. It's possible there may be something of a blockage just after the toilet, causing a backup. I would try to snake the the pipe from toilet out. You may even have to remove the toilet from the floor and do it there if there is no access underneath (like a basement or a crawlspace). I have snaked main drains from the toilets many times, and it's a pain having to re-re the toilet, but often it's the only way.
You need your septic tank cleaned out.

I have seen both.
When the washing machine drains, it can cause the toilet to overflow because both appliances may share the same drain line. If the drain line becomes clogged or blocked, the water from the washing machine can back up into the toilet, leading to an overflow.
The drain is getting plugged and the toilet is lower than the washing machine drain so it is easier for the water to come up in the toilet than to go straight out the drain. Put some drain cleaner down the drain where the washing machine drains and that may solve the problem.

Your toilet gurgles when the washer drains because there is a blockage or restriction in the plumbing system, causing air to be sucked in through the toilet's trap. This can create a gurgling sound as the water drains from the washer.
Use a shower instead of a bath Buy a new toilet if you have an old toilet Turn the taps off if they are not needed Fill the washing machine to the top
Partially obstructed drain or vent line. Could also be improperly tied into the toilet drain/vent. In most codes wet venting for more than 1 fixture unit (i.e. a sink) is illegal. Washing machines have their own section of code due to suds relief, air breaks, and the fact that they discharge a large amount of water into the drainage system very quickly.
Toilet bubbles when the sink drains because there is a blockage in the plumbing system that is causing air to be trapped and released through the toilet. This can be a sign of a clog or ventilation issue in the pipes.

The toilet drains slowly when there is a blockage in the pipes, a clog in the toilet trap, or a malfunction in the flushing mechanism.
