I jumpered the wires for the lower switch together. Now when I hit the on switch, the pump activates.
I thought you did this before w/o success. Oh well.
The latest iteration of Anita, Andreja, and Vetrano has a two position power switch SIMILAR to Vibiemme and other high-end machines. This switch allows the user to fill the boiler and operate all features of the machine w/o power to the heating element.
On any model prior to this latest iteration, the user was cautioned not to let the pump run too long for the possibility that it was not pumping as normal and the heating element COULD be "cooked". While the chances of this are slim, that's why I initially said to disconnect the heating element manually.
You can reconnect the wires for the lower switch and proceed ahead but that should take you back to the beginning of this thread (with the alarm going off) unless the switch/float is an intermittent problem child. This is sorta a known problem area in the earlier machines and was corrected with an improved float device.
