Arrived at location on 7/11/22 - Showed up to check out unit to find that they're having the same problem. Talked to Jason at factory to see if there is anything different that could be done to help this and he said about making the curtain longer. Will quote new curtains and temp gauge to a different person to see what they want to do. Note: Per Joey, ok to order Returned to location on 7/18/22 - Removed old curtains and installed new curtains. Also installed new temp gauge on unit along with hi limit in booster. Checked operation of unit temp went from 185 to 160 and held at 160. After a long period of running the with out the rinse the wash did drop to 152. If problem keeps up the only thing left is the incoming water temp dropping to low. Left maintenance know what was going on.
