Hot water not available

[Konto wurde gelöscht]

Hello,

suddenly yesterday my Vitodens 300 stopped providing hot water.

Boiler have no error, Vicare app shows 48° as setting and 23° as actual water temperature, everything seems working.

Where should I start from?

Thanks

Code 38: 33

Thank´s. The value 33 states that there is an internal undervoltage. In this case, the control unit must be replaced.

Kind regards °ja
