Girard Tankless E4 Service Prep
Use this Lippert/Girard support video page to record E4 tankless water-heater details before service.
Owner-safe checklist
- Record the Girard tankless model, controller display, E4 error, water-temperature symptom, recent weather, and any odor or leak condition.
- Save photos of the controller, exterior label, and visible owner-facing indicators.
- Shut the water heater down for odor, leak, overheating, freeze concern, or repeated E4 behavior, then contact Lippert support or qualified RV service.
