Weekly
1. First, remove the Smart Funnel
®
and set it aside.
2. Now, unscrew the Peak Extraction
®
sprayhead counter-clockwise from the brewer, and set it aside.
NOTE: Any buildup on the sprayhead may restrict water flow, and impact your coffee brewing. For
consistently great coffee, clean sprayheads weekly. Upon visual inspection it may appear that light
passes through all holes in the sprayhead plate, but a thin film of residue can pass light and still
impede water flow.
3. Insert the sprayhead cleaning tool into the sprayhead and by-pass outlet fitting. Rotate several times to
remove any mineral deposits from the fitting.
4. Prepare a warm soapy solution with nonabrasive, liquid detergent (140˚ F). Then use a clean, damp
cloth wetted in the solution to wipe down the sprayhead panel.
5. Now disassemble the Peak Extraction sprayhead by removing the black seal.
6. Submerge and wash all the individual sprayhead parts in the solution. Ensure all sprayhead holes are
fully open and clear of any product residue or mineral deposit build-up.
7. After washing the sprayhead parts, thoroughly rinse the parts with clean water.
8. Reassemble the sprayhead and screw it back onto the threaded outlet fitting. The sprayhead only needs
to be hand tightened.
Machine may need to be re-calibrated due to lime build-up. If machine is cleaned and build-up removed,
machine must be re-calibrated to achieve desired volumes. Refer to programming manual for calibration
routine to verify sprayhead flow and by-pass rate matches programmed flow rate.
