Arrived at location on 2/9/22 - Dishwasher in 2nd floor Terrace crossing is having issues. Not getting up to temp and using too much rinse aid chemical. Checked unit, is on and wash temp is showing 120. Opened and closed door, unit seemed to start heating up. Heats up to above 150, ok. Checked chem lines, found air pockets in rinse aid lines. Chem sensor has chemical in it and pump is only running during rinse, okay. Checked error logs for heat issue. Found multiple error codes related to sump fill level. Customer stated they are able to turn off and on again and unit will work. Likely an issue with the pressure sensor for sump fill level. If unit was not filling correctly it would more consistently not be operating. Will obtain pressure sensor and chemical lines for rinse aid. Returned to location on 2/22/22 - In kitchen, shut off unit. Unplugged unit. Removed bottom and side covers. Remove tubing from bottom to pump and install new. Replace pinch tube for rinse aid l
