Hi, hope you can help. My heating is working fine however I'm not getting any hot water when turning on the tap(s). With the hot water tap turned on the boiler recognises this and the tap symbol appears, the bolier starts to work and I can hear the pump, flame symbol, gas valve and internal pump symbols are all on however still get no hot water. I have tried resetting the unit and also switched the heating off and just run the hot water/warm start, still no joy. There are no error codes. Please help as I need to have a shower :-)

Diverter valve

Waterways plumbing and heating, November 2011

I have an ecomax and mine has just done the same, is it easy to fit? pretty much at the same time my pressure releif valve has gone..could this have caused the other to break? Many thanks

It could be the water diverter valve, I'm having the same problem I have a Vaillant ecomax which is similar, seems to be a common problem. The part needed costs £70-£100 plus vat DIY if you know how
