Q&A for How to Drain a Washing Machine by Hand

Call a repairman, most likely the pump has stopped working. Or, drain it yourself, and buy a replacement pump online.

Simply take the plug out of the socket and take the old fuse out of the plug, then replace with the new one.

Yes. Your machine will most likely start filling it again with the next load, which will cause it to overflow if you do not drain it between washes.

There is not anything in there that boiling water or drain cleaner is going to dissolve or remove. Toys, coins, or anything else that's big enough to stop up the hose cannot get past the drum or through the pump to a point where boiling water or drain cleaner would remove it. If you think a mouse or bugs may have entered the open end of the hose, remove the hose from the back and flush the removed drain hose with a garden hose. Inspecting the fitting where the drain hose was attached with a flashlight should reveal or eliminate any blockages from that end.

This may be due to a malfunction with the sensor that's supposed to tell the machine how much water (if any) is already inside.
