Commercial Dish Machines & Warewashers
Commercial warewashers scale with volume. An undercounter machine fits a bar or small kitchen; a door (hood) type handles a mid-size restaurant; a rack conveyor or flight-type machine runs high-volume dish rooms. Glasswashers are undercounter units tuned for barware, and pot & pan washers handle heavy cookware. Match the machine to your peak rack count, then confirm sanitizing method (high-temp with a booster, or chemical) and utilities on the spec sheet.
Compare commercial dish machines by machine type — the decision that drives everything else. Racks-per-hour, width, and electrical are shown where the manufacturer publishes them. Confirm sanitizing method and hookups on the model's spec sheet before you spec a dish room.
Commercial dish machines: buying guide
The right warewasher is the one sized to your peak rack volume. The models above filter by machine type.
Match the machine to your volume
An undercounter machine fits a bar or small kitchen; a door (hood) type covers a mid-size restaurant; a rack conveyor or flight-type machine runs a high-volume dish room. Glasswashers are undercounter units tuned for barware; pot & pan washers tackle heavy cookware.
High-temp vs low-temp
High-temp machines sanitize with 180°F+ rinse water (usually needing a booster heater) and dry fast; low-temp machines sanitize chemically at lower temperatures with a lower upfront cost. Both must meet NSF/health-code sanitizing standards.
Plan the dish room
Flank the machine with a soiled (dirty) table and a clean (exit) table so ware flows one direction, and confirm the machine's water, drain, and electrical against your utilities.

Frequently asked questions
High-temp or low-temp (chemical) dish machine?
High-temp machines sanitize with 180°F+ final-rinse water and need a booster heater; low-temp machines sanitize with a chemical (usually chlorine) at lower water temperatures. High-temp dries faster and skips sanitizer cost; low-temp has a lower upfront/utility cost. Confirm which a model uses on its spec sheet.
Do I need a booster heater?
High-temp machines need 180°F rinse water; if your water heater can't deliver that at the machine, you need a booster (built-in or separate). Low-temp chemical machines don't.
What's rated in racks per hour?
It's the machine's throughput at ideal conditions — a marketing max, not a sustained real-world rate. Size up from your peak, because dish-room bottlenecks are miserable during a rush.
Where do your specs and prices come from?
Specifications are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn’t published we leave it blank rather than guess. “Street price” is the lowest legitimate published price from an online dealer we track for that exact model — equipment only, and it changes often. Many models here have no published online price and show “check dealer pricing.”
Does this equipment need to be NSF listed?
Storage and dish-room equipment used in a commercial kitchen is generally expected to be NSF/ANSI listed for cleanable, food-safe construction — that’s what a health inspector checks on plan review. We don’t assert a listing for a specific model unless the manufacturer publishes it; confirm the exact model’s listing when you permit your kitchen.
About this data
Last verified: August 2026. Specs are compiled from manufacturer spec sheets and authorized dealer listings; where a value isn't published we leave it blank rather than guess.
Methodology: every dish machine model is compared on the same set of specifications, and dimensions are checked (for sinks, overall width must exceed the combined bowl widths) — figures that fail validation are corrected from the manufacturer model number or omitted. “Street price” is the lowest legitimate published price we've found and can change.
Sourcing: product specs come from the manufacturer; regulatory statements link to the source (e.g. the FDA Food Code and NSF). Code requirements vary by jurisdiction — confirm with the authority reviewing your plans.
