Sliding Aluminium doors grinding?

[Andehh]

We have some high end Sunflex sliders, large triple track design about 18 months old.

 

The leading slider thought has started to noticeably 'grind' when opening & closing, definitely on one set of the wheels only. I have tried everything from hoovering through to pressure washing without making any difference. I have also managed to ''lift'' the back of the door up slightly and move it in case it was a stone stuck between wheels.

 

There is no obvious adjustment on the door, and I am all out of ideas. I also think there are some tiny metal shavings being deposited after using it.

 

Anyone ever comes across this sort of thing on large ally sliders? Have reached back out to the installers, so we'll wait and see!

 

Thanks,

You’ve paid the premium for high end 

Get the company back 

It May be a quick simple fix They  will take the offending door out and see what’s going on

My bet would be one of the rollers has failed. As above the door needs to come out, not a DIY job.

Either failed roller or out of adjustment, I replaced a roller on a family members slider last year but in your case get the manufacturers out to assess.
