Hi. My Vokera boiler doesnt supply any hot water. The central heating is fine but when I turn on the hot water the central heating cuts out. If I select water only nothing happens. The water flow and pressure switches are working okay. The fan doesn't start up so I doubt it woul be anything to do with the airflow swiitch. Any suggestions or advice would be appreciated.

what kind of vokera is it

it may be the thermistor it is easy to test just check what resistance you are getting at the pins if it is 0 replace it if higher than 9 its ok

have you checked for continuity at the hot water flow switch it should buzz when the tap is on
