A restaurant cannot assume it may keep operating normally after hot water fails. Identify affected handwashing, cleaning and warewashing, and contact Maricopa County Environmental Services when an imminent health hazard may exist. Its adopted FDA 2017 rules and local sink requirements apply. Confirm any accepted limited operation and required approval before resuming discontinued work.
What should the manager check without changing settings?
Record which fixtures have usable hot water and which do not. Note the time of failure, any equipment fault messages and whether the loss affects the whole kitchen or one branch. Give those observations to the plumber and county health authority.
Separate these functions:
| Function | What needs verification |
|---|---|
| Handwashing | Required accessible sinks and compliant water delivery |
| Manual warewashing | The approved wash and sanitizing process |
| Mechanical warewashing | The actual machine's required temperatures or chemical sanitation |
| Cleaning | Water needed to maintain sanitary equipment and surfaces |
| Food preparation | Any operation depending on the lost supply |
Do not raise heater or mixing-valve settings as a substitute for diagnosis. Different sanitation methods have different requirements, and hotter delivery creates a scald hazard. Commercial heater shortages cover the diagnosis, while restaurant booster heaters address high-temperature machine requirements.
Can part of the restaurant remain operating?
Food Code Section 8-404.11 requires stopping operations and notifying the authority when an imminent health hazard may exist. It allows an unaffected area to continue and permits specified outage operation under an approved emergency plan. Ask the Department which functions, if any, can continue safely in your circumstances. Portable hot water or a reduced menu is not automatically an accepted solution.
If the problem is limited to one required sink, see the failed handwashing-sink response. If water service itself is lost, use the broader outage checklist.
What should be verified after repair?
Check restored operation at the required fixtures and equipment under actual demand, not just at the heater outlet. Keep the technician's findings and any authority instructions. Section 8-404.12 requires approval before resuming operations discontinued under the hazard rule or law. The county plan-review checklist explains the separate design requirements if repair becomes a replacement or alteration.
