Liquid Level Probe
Cleaning intervals for the probe are to be determined by the user or the service tech, based on water conditions. The
use of water filters, or the type of water filter that is being used can impact the service interval. Intervals can be from
one month to several years, however, replacing rather than cleaning the probe is preferable.
WARNING: Disconnect electrical power before removing access panels!
CAUTION: This procedure involves working with hot water and hot surfaces!
1. Unplug the power cord and shut off the water line.
2. Remove the top cover of the coffee brewer. Locate the heating tank
and remove the top cover.
3. Open the hot water faucet and drain the tank to a level about 3” below
the tip of the probe.
4. Allow some time for the heating tank and liquid level probe to cool
down before proceeding.
5. Clean the tip of the probe using a Scotch-Brite ™ scuff pad.
6. If a white residue is still visible on the probe, remove the probe and
soak it in vinegar or a scale removing chemical. Repeat this step until
the probe is clean.
