Weekly Cleaning - Curtis SERA2B Service Manual

Cleaning the Coffee Brewer
Regular cleaning and preventive maintenance is essential in keeping your coffee brewer looking and working like new.
CAUTION – Do not use cleaning liquids, compounds or powders containing chlorine (bleach) or corrosives.
These products promote corrosion and will pit the stainless steel parts. USE OF THESE PRODUCTS WILL
VOID THE WARRANTY.
DAILY CLEANING
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 the cleaning solution. Clean off dried
coffee, spills and debris.
4. Wipe exterior surfaces with a cloth soaked in clean water to remove all traces of the
cleaning solution.
5. Slide the brew baskets out and clean them with the detergent solution and a soft brush.
6. Rinse and dry the brew baskets. Return them onto the brew rails.
7. Dry exterior surfaces with a clean soft cloth.

4. Clean the brew basket rails with a brush. Rinse with a water soaked cloth. Dry the area
with a clean cloth.
5. Attach the spray head and insert the brew basket into 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
personnel. Disconnect electrical power before removing the 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 water tower. Locate the top of the water tank and remove
the cover.
3. Drain the water tank to a level about 3" below the tip of the probe.
4. Allow some time for the probe to cool before working on the brewer.
5. Clean the tip of the probe using a Scotch-Brite™ scuff pad.
6. 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.
7. When assembling the probe back onto the tank, make sure the tip of the probe is point-
ing downward as illustrated.
