There is no washer in a toilet.
You have to use toilet more
Replace to inlet washer this normally happens when the washer develops a hole
No.
Toilet flappers is the washer underneath the flushing mechanism. Normally black or orange in colour.
When you pull the handle a washer is lifted and the water goes down into the toilet and at the same time the cistern fills up once the washer is back in place from the flushing mechanism
I would use a pressure washer.
If the drain is adequate size, 3inch, then you could.
It needs a new washer in it.
because the flushing washer is broken and needs to be replaced, or the inlet washer is broken and the water is over flowing into the pan
IF your toilet sink and washer are on the same waste line, which they probably are, the problem is't a short trap. Actually since your washer, toilet and sink have different traps it shoudn't effect anything. The problem probably comes from the washer being what is called a "sudds producing fixture". The sudds produced by your washer can actually go up either your toilet or sink waste line. By code the waste for your washer should be tied in to the sewer main 6' from where your waste line goes up for your bathroom. The only solution is to redo the piping from the sewer main and move your waste line for the washer. it won't harm anything. The worst thing that could happen is you'll get suds out of the drain in the sink
Firstly, you have a anti syphon problem, this is causing the drainage and the bubbles are caused by a possible blockage in your main sewer line.
A blocked drain.
