Because the drain is plugged up somehow downstream from it. Not all plugged drains are totally blocked, many are built up with years of grungy goop, often leaving only a small hole. When a sudden onrush of water as from a washer discharging meets this hole it backs up. You need to auger your drain.
See if there is something stuck in the pipes that is clogging it up and causing this to happen.
You can drain it directly into a drain pipe. Just make sure the the top of the drain pipe is even with the top of the washing machine. If not, the water from the washing machine will drain all of the time. There is no valve in the machine to stop the water from draining. The washing machine drains using a pump motor.
could be a multitude of things; undersized waste pipe, backwards wyes or santees, backgraded piping, backed up gray water system
The washing machine is pumping out water faster than the drain pipe can handle. A trap in the drain pipe to which the washing machine hose is attached is required and that makes the water flow slower than you might expect. Having the washing machine some distance from the main drain line requiring a long horizontal run in the machine's drain pipe will also result in a slower flow. Other causes could be: undersized waste pipe, backward wyes or santees, backgraded piping, backed up gray water system. An obstruction such as a checker piece or poker chip could be lodged within the pipe. Such an obstruction acts as a valve or flap that will pivot out of the way when a snake is pushed through the pipe but pivot closed when water attempts to flow through. Nowadays a two inch drain pipe is recommended. Some cities require two inches or larger. Do not seal around where the washing machine hose is hooked onto the drain pipe as this could overload components within the machine.
a washing machine consider as an open loop system when all the disturbances being ignored e.g when the operator try to start the washing machine it goes start even though it don't have water inside the washing machine.
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.
Washing machine filters are cleaned not changed unless they are broken, they are usually inside above the wash bin, check the instructions inside the lid or your owners manual for the location of yours.
Well in the first place it depends what is wrong with it - YOU haven't told us that. - A washing machine is a very complicated machine and can have many problems -not even many handymen fully understand them. In your case, I would recommend calling an appliance technician.
Truthfully, i can't answer this correctly. There is no definite answer, because there are too many variables to count in order to tell you. The type of washing machine, if you are running on generator power, or some other source of energy, even the age of the washing machine itself.
The belt or transmission is likely the problem. Could also be the pump belt if it's one that has a belt, or even debris in the pump intake. - Call an appliance tech, it's an easy fix UNLESS it's the transmission.
Yes, even tough you put it in a washing machine because everything has bacteria
Washing machines are shipped with straps or bolts that hold the tub in place for shipping. If they are not properly removed, then dancing will commence!
