Should opening it manually operate the microswitch ?
I've always assumed it did, but have just bought a replacement head and with the lever fully over, the operating plate is about 2mm shy of the switch, let alone when dropped back into the catch. So is it just supposed to open the valve? Andy Cap |

No, that makes sense. ;-) Defo confirmation, the microswitch is only operated when the motor operates the mechanism, not on manual. -- fred FIVE TV's superbright logo - not the DOG's, it's ******** |

That's my vague reollection too. |
