Aqua-Hot 600-D04 use-care service prep

Use the official Aqua-Hot AHE-600-D04 Use and Care Guide to capture model, controls, and winterization context before support contact.

Owner-safe checklist

• Record the AHE-600-D04 model, control-panel state, heat and hot-water behavior, winterization status, owner-visible fluid level if available, and any displayed warning.
• Save photos of the control panel, safe visible model label or paperwork, and the Aqua-Hot guide title.
• Keep sealed heating components, leaks, exhaust odor, and installed power components for Aqua-Hot support or qualified RV service; shut the unit down if safety is uncertain.
