How Restaurant Dish Machine Repairs Differ
Signs a Dish Machine Needs Service
- Rinse arms spraying weakly or unevenly
- Machine trips the breaker or will not power on
- Machine will not reach final-rinse temperature
- Leaks under the machine or from the doors
Commercial dish machines come from specialist manufacturers, so ask whether the company works on your brand and can get parts for it.

Local Notes for Seattle
Seattle Public Utilities, which supplies Seattle, reports hardness of about 1.5-1.7 grains per gallon (calcium hardness roughly 24-26 mg/L as CaCO3) in Cedar and Tolt supply water (soft). Hard water leaves spots and film on glasses and builds up on dishwasher spray arms and inlet screens, which is worth mentioning when you book a repair.
