To help determine if a fault is with the front board or the sensor, there are self diagnostic tests put on the
front board. To use these, you will need access to the front board display side and the corner of the front
board next to the red four pin connector.
-On an AquaPure, you will need to remove the front cover and use both sides of the cover.
-On a PureLink, drop the power center down and you will be able to access both sets of buttons at the
same time.
