How Restaurant Dish Machine Repairs Differ
When to Call About a Commercial Dishwasher

- Leaks under the machine or from the doors
- Machine trips the breaker or will not power on
- Water not filling or draining from the tank
Have the data plate details ready and ask whether the technician works on your machine type before booking.
Water, Power and Safety First
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
A dishwasher must be grounded; if the home wiring lacks a ground or the plug does not fit the outlet, a licensed electrician should correct it rather than modifying the plug. Source: Whirlpool - Dishwasher User Instructions

What Dishwasher Repairs Cost
Commercial dish machine pricing varies with the machine type and parts, so treat home-dishwasher ranges as a floor. Published ranges:
- Leak repair (including leaking door): $50–$300 Source: HomeAdvisor - How Much Does Dishwasher Repair Cost?
- Heating element replacement: $150–$300 Source: Fixr - How much does it cost to repair a dishwasher?
- Control board / control panel repair: $150–$350 Source: Fixr - How much does it cost to repair a dishwasher?
- Service call fee (often credited toward the repair if you go ahead): $35–$100 per visit Source: Fixr - How much does it cost to repair a dishwasher?
If a repair would cost more than about half the price of a new dishwasher, replacing it is usually the better value. Source: Fixr - How much does it cost to repair a dishwasher?

Local Notes for Portland
Portland Water Bureau, which supplies Portland, reports hardness of bull Run supply about 7-11 ppm (roughly 0.5 grain per gallon, soft); groundwater supply about 80 ppm (about 5 grains per gallon, moderately hard). 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.

Oregon has no license issued specifically for appliance repair that we could confirm, but anyone installing or servicing liquefied petroleum (LP) gas appliances needs an LP gas fitter license from the Oregon State Fire Marshal. Source: Liquefied Petroleum Gas licensing (Oregon State Fire Marshal)
In Oregon, you can check a license with the Oregon Construction Contractors Board Contractor/License Search or report a problem to the Oregon Department of Justice, Consumer Protection.
