What can I do if steam is coming out of the boiler top?

During the heating phase up to 0.5 bar it is possible that steam may be released. If steam or hot water continues to be released after that, the vacuum valve in the top might be covered in limescale or broken. Descale the valve (see glossary). Please be sure that the machine has cooled down and that you release the remaining steam before unscrewing the top of the boiler.

If this does not solve the problem, please contact our customer service team for a replacement vacuum valve.
