GLOW_WORM SPACE SAVER MK11?

HI,

The above boiler works fine, but when I switch the dial to W-ON & H-OFF. The heating still stays on?

Any advice would be great!

THANKS

Do you have a mid position valve in the system ?? If you do, it's probably this that has stayed in mid position after the winter....
