Gen 3: Clean or Replace Float Switch
The float switch is mounted to a bracket over the back left corner of the batch tank. A buildup of residue on the post that hinders the movement of the float is the most common cause of failure of the switch to operate. If this is the case, you can clean (rather than replace) the switch.
