mc58 ... duet water level ... have you tried this?
I have been following your sudsing and tangling issues, and wondered if you found a solution? I am still on the search for a way to increase the water level of my FL Duet washer. I have been noticing that my towels are getting increasingly stiffer and not as white as in the past. I have had my Duet 9600 since Jan this year. I am attribute the stiffness to the fact that the loads are not properly rinsing.
I experimented washing my towels running a regular whitest white wash with extra rinse, followed by a separate rinse cycle with extra rinse. After drying the towels, they were almost as soft as when they were new. I tried the same process when my other loads, and the clothes came out softer as well. I am convinced that these machines use too little water.
I bought a FL thinking they would perform as well as my European FL washer, granted it was ten years older. I was shocked at the miserly water level of the American model.
