KENWOOD - K714WM14 Waste pipe

Hi,

recently we have been having issues with our washing machine draining. I've checked the filter and that was clean. The next thing I checked was the waste pipe that fixes on to the sink outlet.

There seems to be a small black object stuck in the pipe. When I move this slightly it allows the machine to drain. What I am not sure about is if this is meant to be in the pipe or not. Is it some sort of non return?

Im hoping someone can let me know what it is. I have attached an image that shows the object in the pipe.

Thank you

Kenwood K714WM14 intermittent draining issue at sink waste hose connection

The problem
The washing machine was not draining properly. The filter had been checked and was clean. A small black object was seen stuck in the waste pipe where it connects to the sink outlet, and moving it slightly allowed the machine to drain.
Likely cause
The accepted reply identified the black object as a non-return valve, with the likely issue being dirt or debris around or under it causing it to stick and restrict drainage.
What fixed it
Clean around and under the suspected non-return valve so it can move freely. The thread was marked solved, but no final confirmation from the owner described the exact repair result.
Checks to try
  • Filter checked and found clean
  • Waste pipe at sink outlet inspected
  • Moving the black object in the pipe allowed draining

Yes it must be a non-return valve. Make sure it's all clean around and under it so it isn't sticking.
