What does the egg timer mean on a Vaillant Boiler?
The primary function of this flashing is to engage the boiler’s anti-cycling feature.
This feature acts as a protective mechanism, preventing the boiler from constantly switching between ‘on’ and ‘off’ states, thereby reducing wear and tear and avoiding excessive energy consumption.
The egg timer icon, therefore, serves as a visual indicator of this protective cycling process in action.
Note that the frequency and duration of the icon’s flashing can reveal more about the boiler’s condition.
Occasional flashing might be normal, especially when the boiler is adjusting to varying heating demands.
However, continuous or prolonged flashing may signal additional issues, like system imbalances or potential malfunctions, sometimes leading to boiler replacement being required.
