ORBEK support FAQ

Common questions about manuals, registration, and support for this brand.

  • What does the E1 error code mean on my ORBEK water heater?

    The E1 error code typically indicates over-temperature protection activation. This happens when the outlet water temperature exceeds the safety limit (often 149°F/65°C). The unit cuts power to prevent scalding and will reset once the temperature drops.

  • How do I contact ORBEK customer support?

    You can contact ORBEK customer service via email at service@orbek.com for assistance with warranty, troubleshooting, or installation questions.

  • Can ORBEK tankless water heaters be installed horizontally?

    No, ORBEK tankless water heaters generally require vertical installation to ensure proper function and safety. Always refer to your specific model's manual for proper mounting instructions.

  • Why is my ORBEK water heater not heating water?

    Check if the breaker is tripped (for electric models) or if the gas supply is on (for gas models). Ensure the water flow meets the minimum activation rate (usually around 0.5 GPM). If the issue persists, check for error codes on the display.

  • Does my ORBEK water heater need winter maintenance?

    Yes. While some units have anti-freeze protection, if the device is installed outdoors or in an unheated area exposed to freezing temperatures, it should be drained when not in use to prevent internal damage.
