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
- Leaks under the machine or from the doors
- Machine will not reach final-rinse temperature
Commercial dish machines come from specialist manufacturers, so ask whether the company works on your brand and can get parts for it.
If Your Dishwasher Is Leaking
Shut off the dishwasher's water supply during repairs or whenever it is leaking; the valve is usually under the kitchen sink on the branch line that runs to the dishwasher, and it closes by turning clockwise. Source: GE Appliances - Dishwasher Water Shut-Off Location
Before inspecting or working on a dishwasher, unplug it or switch off its circuit breaker. Source: Whirlpool - How to Fix a Leaking Dishwasher
