I have a vaillant turbo max 24e and a wired thermostat which just has TOWERSTAT SP written on the front.
When the hot water is switched on, it somehow cuts out the boiler which I shuts down the central heating system.
The water when switched on, stays hot for a minute or 2 then goes cold and never gets back hot.
Because of this, as I said the central heating system switches off.
Recently (3 weeks ago), the diverter valve was changed which kept the water hot for a while.
The current problem started a week and a half ago.
The heating goes off when the hot water is switched on.
In addition, when the hot water is switched on, the green light on the boiler keeps flashing, if this helps.
Sometimes I am able to restart the heating system when I adjust the temperature on the wired thermostat but I do not understand why I have to keep doing this
