Commercial Kitchen Appliance Repair. Arrived at the location on 4/17/23 - the screen would lock up. Found an error stored fill failed I did check and found the filter screen fairly clogged .at the ionized water connector I did clean the screen filter and checked operation. I drained the unit and attempted a rinse. The unit did complete a rinse ok. The unit is ready to use. Instructed the customer to run a full wash cycle and let us know if they need further assistance.
