Replace integrated dishwasher water pipe

lky2k23

Can someone please how to fix this? 

It's eroded to the point of no return and the integrated dishwasher I believe it's the cold water supply for, I won't be able to move. 

So I'll need to cut and refit.

Thanks

Normally you can unscrew the other end of the water pipe from the dishwasher and replace like for like - obviously ensuring the water is turned off. If not, can you post a photo of the rear of the dishwasher?

^^^^ This.  These pipes are pretty much standard for any dishwasher or washing machine.  Just turn off the water supply, unscrew the old one, clean up the coupling on the supply pipe, then fit a new one.

I won't be able to get behind the dishwasher. It's integrated and blocked in now by a skirting board - moving out before the end of the year so not willing to disrupt that much.

When you say "skirting board" - do you mean plinth?  If so, these are usually just clipped on to the cabinet legs with a spring clip, and can be popped off in seconds.  If the dishwasher is integrated, it's usually just a case of removing the door trim panel and then sliding the machine out.  Apologies if I'm over-simplifying, obviously I don't know the layout of your particular kitchen - but usually it's not at all difficult to remove a dishwasher, even if it is built-in.

As above, turn off water, pull off the plinth, open dishwasher door, see if there are any screws going up into the work surface, remove them and pull dishwasher out. You need to replace the whole blue hose, make sure there are rubber washers in each end and don't over-tighten, hand tight then just a little bit more.

No, unfortunately this is a standard skirting board that runs to the dishwasher, from the bottom of the machine to about 6inches up. No plinth. Gloss painted skirting to a nearby corner also, so would be much more aggravation than what I hope could be,
cut the water pipe and do...

Okaaaayyyyy....... Thinking about it, do you know where the corrosion is coming from?  The hose & fitting that attaches the machine to the water outlet is usually all plastic.  Just wondering whether the corrosion is coming from the coupling on the metal pipe.  And it looks like a compression fitting.  What I'm thinking is, turn off the water at the mains and unscrew the plastic nut.  Then look at the metal fitting.  If it's that that's corroded, you can remove it and replace it with a new one very easily.  Then  give the plastic fitting a clean-up and screw it back into place.  Given that you've provided pictures, I'm assuming you can get to that end of things easily enough - it's the back of the dishwasher itself that would be the problem?

That's right. I think there was a leak from an old sink that I ignored. 

The issue with unscrewing the plastic nut is - I've had a small twist and it feels like it's going to break (disintegrate!), so need the plan for if it does.

The nylon nut is stronger than it looks. I think it is unlikely to break. The two risks are that either the thread or mating face on the tap are corroded preventing resealing or that the joint between the 15mm pipe behind the tap and the tee coupling in the wall will be broken by twisting.

This is what I would do:

• Buy a new 15mm x 3/4" compression wm tap from Screwfix
• make sure you have some PTFE joint tape.
• turn the mains water off and drain
• grasp the body of the wm tap with an adjustable spanner to prevent turning
• unscrew the nylon nut with firm pressure.

Clean all the corrosion off. If you are lucky all that will be needed is a new washer inside the nylon nut. If the wm tap is damaged unscrew it and fit the new one. Ideally replace the olive but if you can't get it off the old one should seal OK with some PTFE tape.
As you can tell, I am not a plumber

If it snaps can you not buy and fit a new rubber/plastic hose ,it looks like the one on a washing machine ,you can buy at the likes of Screwfix / Toolstation /B & Q etc.
