  If you notice water leaking from your Ariston Water Heater, it could be due to several reasons: * Improperly tightened pipes: Ensure all pipe connections are secure. * Damaged gasket: Replace the gasket if it's broken. * Incorrectly tightened flange: Check and tighten the flange bolts. Additionally, excessive dripping might occur due to high water temperature, high water pressure, a missing expansion vessel, a blocked drainage hole, or a broken drainage pipe. If necessary, install an expansion vessel, clean the valve hole, or replace the discharge pipe. Also, if the Pro-Tech anode malfunctions due to low water hardness, replace it and ensure proper water hardness. If the product is full of water and power is not supplied, replace the device and ensure proper installation.

  If your Ariston Water Heater delivers cold or insufficiently hot water, first, raise the water temperature setting. If the issue persists, check for error messages on the display and follow the instructions in the “Errors” table. Also, check the voltage on the power terminals and inspect the wires and connections for any damage. Ensure sufficient airflow to the evaporator by regularly cleaning the grilles and ducts. Verify that the unit is switched ON and check the mains power supply. Be aware that using a large quantity of water while the product is heating can also affect the temperature. Finally, check for sensor errors 210 and 230, even if they appear only occasionally.

  If you notice water leaking from the pressure safety device of your Ariston Water Heater, keep in mind that some dripping is normal during the heating phase. To minimize this, install an expansion vessel on the delivery system. However, if the leak continues even after heating, check the calibration of the device and the mains water pressure. Warning: Never obstruct the device’s discharge outlet!

  Sonya Davidson DDSAug 29, 2025
  If your Ariston Water Heater has a reduced heat pump operation and the electrical heating element is almost always on, consider that this component depends on climatic conditions. Ensure the product is powered with the correct voltage. Check the evaporator, grille, and conduits to ensure they are clean, because the evaporator could be obstructed or frozen. Also, check the display for error messages related to the heat pump circuit.
