Dishwasher Cold Water Supply Hose Leaking

[Mcknze21]

Hi

I have a dishwasher cold water supply that is leaking (See Photos).
My initial thought was the washer was maybe gone but looks ok.

Thought about PTFE tape but everywhere says this shouldn't be needed?

Any suggestions?

Thanks!

Looks like maybe the blue handle is stopping the nut from tightening all the way

You think that’s maybe all that is? What would you recommend to configure differently?

Remove the blue bit and see if the nut will tighten more ?

Removed this and nut is as tight as can go

Inspect the part of the isolator that makes the seal carefully (use good light and a magnifying glass) for cracks or scratches that might be responsible. If you think it's okay, replace the washer in the hose. You need to tighten the hose coupling up reasonably tight in the first instance then, a day later check it's still tight. If you're paranoid like me you'll also check for tightness after a couple of weeks and then every six months.

Leaks can cause a lot of damage. So, if you need to replace the hose use an authentic spare from the washing machine manufacturer, if you need to replace the isolator use a branded good quality one such as 'Ballofix (TM)' made by Pegler Yorkshire, i.e. not cheap stuff you've found on eBay!

Still drips ?

Yeah thats it side on. Tightened as far as it goes.

Might go with what Chuck has said.

As chuck says replace the washer with a new one, sometimes new washers are thin so you can put two on if that is the case.
Screwfix and Toolstation have the washers pack of 10 for little over a pound.

The old one may look ok but has got hard .
