Warewashing selector
Stop guessing. Match your peak rush to the right dishwasher class.
Tell it what lands in the sink, how hard the rush hits, and what the kitchen can physically take. The result is a class verdict, capacity slack, finance framing and live Craven machines.
3-4racks/hour is the common machine trigger in Craven’s guide
40-60racks/hour is hood or pass-through territory

01 / What are you washing?
02 / Peak pressure
This drives the verdict. Craven’s guide says size by peak racks/hour, not just daily covers.
Used only to sanity-check racks. Craven’s worked example uses about 18 covers per mixed rack.
Live cards show real prices; finance appears when a live item is above £1,000.

The selector leaves headroom for the dirty-rack spike at the end of service.
Bar path
Glasswasher
For mostly glassware, especially bar service.
- Live category: commercial glasswashers
- Some Craven products state 25 pint glasses per rack and up to 1000 glasses/hour
Compact path
Undercounter dishwasher
For cafes, small restaurants and mixed dishwashing where space matters.
- Craven guide trigger: around 3-4 racks/hour
- Product data commonly shows 500 x 500mm racks and up to 40 racks/hour
Rush path
Hood or pass-through
For a proper service rush where loading speed and rack flow beat compactness.
- Craven guide band: 40-60 racks/hour
- Above that band, treat this as a Craven spec call rather than a blind basket add
