• Initial set up required - see page 4.
• Make sure lid is closed.
• Evaporation can occur over time - reservoir may need to
be refilled. See initial set up on page 4.
• Requires a minimum of 4 cups (20 oz) to begin brewing.
• Check sprayhead holes, clean if necessary. See deliming
instructions (step 5) on page 8.
• Evaporation can occur over time - reservoir may need

• Some water is always absorbed by the coffee grounds
and filter. You may need to adjust water input
accordingly.
• Use BUNN paper filters.
• Sprayhead is missing.
• Decaffeinated, fine grind coffee or softened water is
used. See bottom of page 10 to order correct sprayhead
or paper filters.
• Plug in brewer and turn on vacation switch on side
of brewer. Allow 15 minutes for water to heat to proper
temperature.
• Warmer switch should be in the “on” position. (NHBX)
• If using a STX with thermal carafe, pre-heating will increase
the time your coffee will stay warm.
• Normal while water is heating.
• May be time to delime. Refer to page 8.
• Make sure lid is fully open.
• Brewer is not designed to hold water in upper tray for an
extended period of time.
• Remove top lid to ensure rocker arm is snapped in place
and rubber stopper area is thoroughly cleaned.
