That's just the filter gauze so that's ment to be there.
So just screw the fill hose onto the water tape and keep that in place and it will be fine.
That red gauze is like filter so if you get bits on sediment through the water it collects in there instead of getting into the dishwasher.
Hope this helps you. If you need anymore info just get back to me,
Just double checking. I'm talking about the water inlet in the machine, not the hose pipe ie the water entrance in the machine itself. Just inside where the water goes in is the gauze/sieve type red disc.
Ok so its on the water inlet valve itself on the back of the dishwasher at the bottom?
If so then yes its the same. There are just filter gauzes. As when fitting a new dishwasher theres nothing in the water valve or hose you need to remove. Its just a case of pipeing it up.
Your very welcome.
