Aqua-Hot 175 controller service prep

Use the Aqua-Hot 175 product page to prepare model, controller, heat, hot-water, and service-routing details.

Owner-safe checklist

Record the Aqua-Hot 175 model, serial if visible, controller state, hot-water symptom, cabin-heat symptom, and visible condition.
Save photos of the model label, controller, display if present, and visible condition from normal owner access.
Shut the Aqua-Hot system off for leaks, unusual odor, overheating, unsafe hot-water condition, or repeated control symptoms.
Use Aqua-Hot support or qualified Aqua-Hot service for heating, exhaust, fluid, installed power, parts, warranty, and repair decisions.
