AutoPOD™ Common Issues
Pressure Too High Error Message
Model: AutoPOD™
Common Cause(s): incoming water pressure pushing or exceeding 90 psi or the weight an grind of the product
Troubleshooting: Check the incoming water pressure and check the weight and grind of the product.
Repair: Order preset pressure regulator assembly with ttings, (BUNN PN: 41847.1002), and install onto the .75
hose thread tting located in the rear of the machine. The pressure regulator will be factory set at 50 psi. Brew a
single cup of coffee to verify the “Pressure Too high” message has been eliminated during the brew cycle.
Prevention: N/A
Additional Notes: The sprayhead assembly and seal is monitored by a pressure switch which activates between
40-45 psi. Weight and grind of the product is also a restriction factor that can have an affect on the brewing pressure
which can increase and activate the pressure switch during the brew cycle.
Sprayhead Seal Leaking During Brew without Pressure Too High Error Message
Model: AutoPOD™ and AutoPOD™ with Booster Pump
Common Cause(s): Sprayhead seal may have exceeded the recommended number of brews for seal replacement
and now needs to be replaced
Troubleshooting: Follow sprayhead cleaning instruction in the manual. Ensure sprayhead seal is installed with the
ridge facing up.
Repair: Replace sprayhead seal.
Prevention: Cleaning and preventive maintenance training.
Additional Notes: If leak still occurs after changing sprayhead seal, machine could have an alignment issue with the
pod holder to the sprayhead assembly. This will require replacement of the entire ejector assembly. See Illustrated
Parts catalog for replacement part number.
Water Dripping After the Brew Cycle is Complete
Model: AutoPOD™ and AutoPOD™ with Booster Pump
Common Cause(s): failure of the inlet solenoid (ll valve)
Troubleshooting: Adjust the appropriate “Air Time” menu that correlates to large and small switch that purges the
brew tank at the end of the brew cycle. A second option or an addition too, adjust the “air pump power” menu which
will adjust the air pressure for the brew cycle purge.
Repair: Make necessary adjustments.
Prevention: N/A
Additional Notes: New guide tube being developed to replace the original style stream guide tube to help eliminate
the dripping after brew cycle is complete. Estimated implementation of new guide tube is August 09.

Heating Too Long Error Message
Model: AutoPOD™ and AutoPOD™ with Booster Pump
Common Cause(s): Heater relay on greater than 6 minutes.
Troubleshooting: Check for open element, limit thermostat and heater relay coil. If components check good, the
main control has a triac on the board that supplies the output voltage to the tank elements. Check CBA.
Repair: Replace the faulty component(s).
Prevention: N/A
Additional Notes: N/A
Motor Obstruction Error Message
Model: AutoPOD™ and AutoPOD™ with Booster Pump
Common Cause(s): Motor current increased over .55 amp great than 3 seconds.
Troubleshooting: Check for defective index motor sensor which does not see a slot in the position disc and will over
run the position slots and jam creating the error message. Another reason could be machine or ejector assembly
damage due too negligence (dropping) of the equipment, the components or ejector linkage could be out of alignment which relates to increased restriction in the linkage assembly during the brew and pod eject process and will
display the “Obstruction” error message.
Repair: Clean, repair, or replace the faulty component
Prevention: Be aware of the instruction on the outside of the original shipping carton. “Delicate Electrical Instru-
ment- Handle With Great Care” and this side “Up” message.
Additional Notes: N/A
