Is my sad Phalaenopsis orchid saveable?

[katiepeaches]

Hello,

First off I am an absolute beginner so please bear with me! I purchased a healthy looking phalaenopis orchid from the supermarket around 8 weeks ago- the leaves started to wilt very quickly and while the plant has held onto all of its flowers they have drooped badly. I assumed this was because she was badly dehydrated and I have been watering once a week with a 10 min soak in pre-boiled water followed by a longer drying off period before returning to the pot. I have not yet replaced this or the medium.

Now that the orchid is in clear need of attention I have inspected the roots and I am trying to figure out whether or not they are in a healthy enough state for her to stand a chance of recovery. My main concerns are the dark spots on the roots, and the exposed wiry sections along the root lengths. They are not mushy, but there is a very slight damp smell. Any guidance on how to best care for the plant going forward would be much appreciated. I have attached a couple of photos which will hopefully make things a little clearer

Thank you in advance!
