kitchen sink waste

[taffy06]

My waste from kitchen sink is draining in to my washing machine not the outside but there is no blockage in outside waste pipe!!...help

there must be a blockage somewhere, or the non return valve has gone in your washing machine

Ensure the discharge hose form your washing machine at some point is higher than where it connects to the kitchen sink this should help also.washing machine come with a plastic u guide try and use them if you've got them.

How long have you lived there?

Has it ever worked properly (with this washing machine)?

When did the problem start?

What was the last plumbing work that you had done, and when?

How does the washing machine waste outlet connect to your waste system - trap spigot or standpipe?
