The shut off valve/pipe for the hot water leaks and has to be replaced. I disconnected at the valve the hot water hose for the washing machine because just using cold/cold still tried to access the hot water line causing it to still leak because of, I'm assuming, a vacuum situation. The hose end is now in a bucket next to the machine because water still leaks from the end of the disconnected hose for some reason when I try to wash a cold/cold load. Why is water coming from a disconnected hose? I tried disconnecting it only from the back of the machine, but it just leaks on the floor from the connection port so a bucket is the only solution for now. BTW, the machine is over 30 years old and still working fine.
Washing machines don't just use hot only or cold only; they often mix the two. When this happens, the pressure inside the valves will push some of the water out the hot connection.
How to fix this? Buy a short, cheap, flexible hose, cut it in half, fold over the end, and hold it down with a zip tie. Then screw the end into the washing machine. Should be close enough for government work.
