Worcester 24i junior not heating water at all? - resetting worcester 24i junior boiler

We have a Worcester 24i junior boiler for our heating gas / water.

Lost a few weeks ago the entire city water for a day. Since then heats the water in the boiler only when heating is turned on.

Now the hot water never ceased, when the heat is on. The pressure is 1.5 bar, the Radiators have been bled recently we read a series of questions such as this mission, but no solution.

The button "Reset", the manufacturer, on top of the boiler on the left side, there is nothing!

I have not for the boiler.
