Possible Causes

Heater installed in unheated space without frost protection, No drain-down during freezing conditions, Failed built-in anti-freeze function (if equipped), Lack of insulation on pipes

How to Fix / Troubleshooting

Safety first: Turn off power and water supply. Do not energize a frozen heater.

  • Thaw slowly: Allow the unit to warm naturally or use gentle ambient heat. Do not use open flames.
  • Inspect for leaks: Once thawed, slowly pressurize the system and check for cracks in the tank, heat exchanger, or fittings.
  • Replace damaged parts: Any split pipes, fittings, or tanks must be replaced. A burst tank requires full heater replacement.
  • Implement freeze protection: Insulate pipes, relocate the heater, or ensure anti-freeze mode is enabled according to Ariston instructions.
