I've got no hot water, C/H OK. Tank stat has been changed, and is OK. The H/W valve is a honeywell one, and I've opened it manually to let water through to no avail. I've taken the motor out, and manually turned the spindle, but still no luck. Can the valve become separated in the pipe from the spndle, so even if you turn it by hand it's still closed?
The valve is a V4043H
Its an indirect system, and it appears that the boiler is not being called for H/W when you press the button on the programmer.
The spindle could of snapped inside the body, but would be very rare as there's not enough force from the actuator head to do this. The spindle will only turn quarter of a turn to change from heating to water and heating, so check you haven't turned this too much.
If you hold the pipe A outlet, this is for heating, then turn the valve to see when pipe from port B becomes hot. This will be heating the water.
