I bought this a few months back. Been happy with quietness but wonder if it’s compatible with Calgon. Found brown specks on some porcelain dishwasher and cutlery. Overall love it and ease of use. Also the efficiency of the cleaner will scratch glass over time, it seems. Great unit no leaks looks great.  Trying to figure out if its my water. Maybe a liquid detergent is better than the powder. 90% of the time u will be happy
