I have a Vaillant TurboMax Plus 828e Combi boiler that has a problem with DHW. I have replaced the diverter valve and cleaned up the heat exchanger but the DHW is not activated when I turn on the hot water tap, the water runs cold.
Could it be the Aqua sensor or something else?
I can use the warm start feature but only when I turn the hot water temp setting on the boiler all the way.
Any help appreciated.
