There seems to be two different qualities with these braided hoses. The cheap ones fail often and the good ones last for 10 years plus.

If you fit a good quality hose you should have no problems , but check every now and then under the sink and if any of the braids has changed or moved, replace the hose immediately.

I have seen two hoses let go, One with enormous damage.

How can a stainless steel hose rust?

electrolysis perhaps? only guessing but have you ever felt the electricity generated by the flowing water in your shower?

There are different grades of Stainless.

Some grades are rubbish and don’t take long to corrode or rust.

I have seen stainless steel condensate trays in refrigeration cabinets with rust holes in them less than 2 yrs old,while others 25 yrs old are still fine and look like new.

Mostly either 304 or 316 (marine grade).

I can inform those interested forumites that Miele drums are at least 316 grade.

I have the perforated inner front loader perforated drum and the outside solid housing 3 metres away as I write this.

Each has had at least 500 fires lit in them over the years, both have a smidge of surface rust but no sign of failure.

The housing drum has absolutely perfectly positioned holes from the factory for this purpose. Installed a damper in the base last year.

Can burn wood from twig size to logs 600mm in dia no probs.
