Water Not Heating
This procedure addresses malfunctions related to the water system failing to reach or maintain the necessary temperature for hot beverage dispensing.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Live 120V+ measurement required on heater circuit.: Verify PPE. Stop if unsure.
- Because this involves live-voltage components, any investigation into the heating circuit must be performed by a qualified technician. Furthermore, do not proceed with any electrical testing without the presence of a qualified technician.
