....., this mean ive changed the wrong micro switch ... ? the one i
suspected was on the back of the hot water flow sensor .. for want of a
better cescription ..ther is only 1 microw switch on this item driven
by a rotating cam, that has a return spring ..


are the other 2 switches on the valve assembly directly over that one
.. ? seem to be locked with locking wire ..

The diverter valve has two microswitches on top - as the shaft moves up,
one changes from NC to NO, the other from NO to NC

You need to make sure that the they're changing over properly
