Washing machine using cold water only

appliances

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.

The hot and cold water enters what amounts to a mixing manifold inside the washing machine. When cold water flows into the manifold, the pressure inside the manifold is necessarily higher than ambient pressure. Since both the hot water electromagnetic valve as well as the feed hose are now open, they allow water to flow out of the manifold. You should remove the hose from the washing machine and plug the hose attachment nipple using a flat screw-on plug cap with a sealing washer inside. It's possibly cheaper than butchering a hose to fashion a plug.
