i had a problem with my central heating, my fault to start i managed to drill through one of the cables to the junction box, i repaird the cable and now i have no hot water, but i do have ch.
i have tested the 3 port valve and it doesnt seem to be working correctly, ??
i have 240v on the grey wire when just hw is called for and have 240v on grey white and orange when ch called for,
the motor is also very hot.
when i took the motor off it moves but in just one direction.
is this a valve problem or a wireing fault somewhere else
thanks
