What to do if Ariston Water Heater water is boiling?
- KKaren GarciaAug 13, 2025
If the water from your Ariston Water Heater is boiling, with steam coming from the taps, the following could be the reason: * High level of scaling of the boiler and components. To resolve this, turn off the power, drain the unit, remove the sheath of the resistance and remove lime scale inside the boiler, being careful not to damage the enamel of the boiler and the sheath resistance. Repackage the product as in the original configuration; it is recommended to replace the flange gasket. * Probe error. Check for the presence of error code E5.
