Cleaning the Gold Cup Brewer
Regular cleaning and preventive maintenance is essential in keeping your coffee brewer in good working condition.
CAUTION – Do not use cleaning liquids, compounds or powders containing chlorine (bleach) or corrosives.
These products promote corrosion and will pit the stainless steel. USE OF THESE PROD-
UCTS WILL VOID THE WARRANTY.
1. Mix dishwashing liquid in warm water to make a mild cleaning solution.
2. Drain the drip tray. Wash the tray and screen. Dry these parts.
3. Wipe exterior surfaces with a cloth moistened with detergent solution. Clean off dried
coffee, spills or debris.
4. Wipe exterior surfaces with a cloth soaked in clean water to remove all traces of cleaner.

cleaning solution.
8. Rinse and dry the brew basket(s). Return them onto the brew rails.

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: This procedure is to be performed only by qualified service per-
sonnel. Disconnect electrical power before removing access panels!
This procedure involves working with hot water and hot surfaces!
1. Unplug the power cord and shut off the water supply.
2. Remove the top cover of the unit. Locate the top of the tank, make sure it is
cool, then remove the cover.
3. Drain the tank to a level about 3" below the tip of the probe.
4. Clean the tip of the probe using a Scotch-Brite
5. If a residual white layer is still visible on the probe, remove the probe and soak
it in vinegar or a scale removing chemical. Repeat this step until the white layer
is removed.
6. When assembling the probe back onto the tank, make sure the tip of the probe
is pointing downward as illustrated.
