The error will appear after the Open/Close switch has been depressed and the pod drawer
cannot close completely because of an obstruction. The Path Clear threshold is actually a
self-programmed threshold based upon the last successful closing of the drawer. The starting
default .27 amps and the self-programmed value is raised and lowered depending on the last successful closing of
the drawer. The Path Clear message comes up when the self-programmed value .1 amps for 20ms (one thousandth
of a second) has been exceeded.
How to Drain the Hot Water Tank
Step 1:
Disconnect the power and water supply to the brewer. Allow the brewer to cool before proceeding.
Step 2:
Remove 6 screws securing the rear panel. Remove the panel. Place the brewer next to the sink.
Step 3:
Direct the drain hose into the sink. Remove the clamp and plug.
Step 4:
Allow water to siphon out of the tank.
Note:
A small amount of water will remain below the fill tube. If necessary, insert a siphon hose through one of the
grommet holes to remove the remaining water.
Step 5:
Replace the plug and clamp onto the drain hose.
Step 6:
Replace the rear panel and tighten the 6 screws.
