EcoLab: dishwasher protocol

ops #ecolab #boh #kitchen #checklist

The kitchen dishwasher is a low-temp chemical sanitizing machine (not hot-water like the glasswasher). This means sanitizer concentration matters and gets tested.

Chemicals

Dish Solid (detergent block) — front-left reservoir
Dish Rinse (rinse aid) — front-right reservoir
QSan sanitizer concentrate — under-sink injector line

The injector pulls QSan into the final rinse cycle. Concentration target: 150-400 ppm quaternary ammonia.

Daily check (open)

[ ] All three chemical lines feeding properly (visual: line not kinked or empty)
[ ] Filter basket empty and clean
[ ] Wash arms spinning freely

Daily check (close)

[ ] Empty filter basket
[ ] Run cleaning cycle empty
[ ] Wipe interior
[ ] Crack door to dry

Testing sanitizer concentration

Test at the start of every shift AND when EcoLab tech visits.

See titration testing for procedure.

Target reading: 150-400 ppm.

If below 150 ppm: STOP using the dishwasher, hand-wash in 3-comp sink, call EcoLab same day.

Weekly

[ ] Descale (Monday, before service)
[ ] Test the rinse temperature — should hit 120°F minimum
[ ] Inspect chemical injector tubes for cracks or kinks

DOH note

This machine relies on chemical sanitization, not heat. Sanitizer concentration logs are part of our food safety log. If a DOH inspector asks, you point at the log + the test strips on the wall.
