Arrived at location on 3/21/23 - Unit has not been making ice for a little bit now. I removed the old filter and replaced with one they had on hand. I took the unit apart and cleaned and sanitized all removable parts. Cleaned evaporator the best I could with the tight room I had. This is an old unit that shoots water up to the evaporator. Found that there was a ton of mineral build up in the reservoir and inside of the nozzle. Cleaned all of it out, however there are two holes that have large rocks jammed inside that aren’t distributing water to the evap. A push pin could possibly get them out. Once unit was cleaned and sanitized I put it back together and had it go through a few wash cycles. Turned unit on and watched it make two batches of ice. The nozzle that distributes water across the evap isn’t getting enough pressure to shoot water into all the holes of the evaporator. I believe the water inlet valve is clogged. Customer would like water inlet valve ordered and replaced. Retur
