Operating Instructions
To begin brewing, ensure a clean decanter is properly placed on the warmer plate. Fill the brewer’s funnel with the desired amount of ground coffee, adhering to recommended coffee-to-water ratios for optimal flavor. Add the appropriate volume of fresh, cold water to the reservoir, observing the indicated level markings.
Activate the brewing cycle using the designated control. The brewer will automatically heat the water and dispense brewed coffee into the decanter. Caution: Funnel contents are hot! Always handle with care. Monitor the brewing process and address any unusual noises or malfunctions immediately.
Filling the Decanter
Prior to brewing, carefully inspect the decanter for any cracks or scratches. A damaged decanter poses a significant safety risk and should be discarded immediately. Ensure the decanter is clean and dry before use, preventing contamination of the brewed coffee. Position the decanter securely on the warmer plate, aligning it properly with the brew funnel.

Brewing Process Overview
The Bunn CW series brewers utilize a straightforward brewing process. After ensuring the decanter is correctly positioned, initiate the brewing cycle by pressing the appropriate button. The brewer will automatically heat the water and dispense it through the coffee grounds. Caution: The funnel contents are hot; exercise extreme care during and after brewing.
Monitor the brewing process to ensure proper water flow and coffee extraction. Once brewing is complete, allow a brief settling period before carefully removing the decanter. Always use caution when handling hot liquids and surfaces. Regular cleaning and maintenance are crucial for optimal brewing performance.
Cleaning and Maintenance
Regular cleaning is vital for maintaining optimal performance and extending the lifespan of your Bunn CW series brewer. Daily cleaning should include wiping down exterior surfaces and thoroughly rinsing the brew funnel. Crucially, decalcifying the brewer is essential to remove mineral buildup, ensuring consistent water temperature and preventing damage.
Follow the decalcifying instructions carefully, using a Bunn-approved descaling solution. Rinse thoroughly after decalcifying to remove any residual cleaner. Consistent maintenance, including these procedures, will help prevent issues and uphold the brewer’s warranty.
Daily Cleaning Procedures
To ensure optimal performance and hygiene, implement these daily cleaning steps for your Bunn CW series brewer. Begin by disconnecting the brewer from the power source. Thoroughly rinse the brew funnel after each use, removing any coffee grounds or residue. Wipe down all exterior surfaces with a damp cloth, paying attention to areas prone to spills.

Decalcifying the Brewer
Regular decalcification is crucial for maintaining your Bunn CW series brewer’s efficiency. Mineral buildup can impede performance and affect coffee flavor. Use a Bunn-approved decalcifying solution, following the product’s instructions carefully. Typically, this involves brewing a solution of descaler and water through the system.
After decalcifying, thoroughly rinse the brewer by brewing several cycles of fresh water to remove any residual descaler. Frequency depends on water hardness; areas with hard water require more frequent decalcification; Ignoring this step can lead to costly repairs and diminished brewing quality.
Troubleshooting Common Issues
If your Bunn CW series brewer isn’t heating, first check the power supply and ensure it’s properly connected. A tripped circuit breaker could also be the cause. For coffee brewing problems, verify the water level and ensure the brew funnel is correctly positioned. Clogged spray heads can also hinder proper brewing; clean them regularly.
Refer to the error codes section for specific diagnostic information. Caution: hot surfaces present a burn risk. Always disconnect power before attempting any internal repairs. If issues persist, contact Bunn-O-Matic support for assistance – details are provided within this manual.
Brewer Not Heating
If the Bunn CW series brewer fails to heat, begin by verifying the power connection – ensure the unit is securely plugged into a functioning outlet. Check the circuit breaker or fuse box for any tripped breakers or blown fuses. Confirm the brewer’s power switch is in the ‘on’ position. A faulty heating element is a potential cause, requiring professional diagnosis.
Inspect the thermal fuse; a blown fuse will prevent heating. Caution: always disconnect power before inspecting internal components. If these steps don’t resolve the issue, contact Bunn-O-Matic support for further assistance and potential repair options.
Coffee Not Brewing Properly
If your Bunn CW series brewer isn’t brewing coffee correctly, several factors could be at play. First, ensure the correct coffee-to-water ratio is being used. Verify the grind size is appropriate – too fine can cause clogging, while too coarse results in weak coffee. Check for mineral buildup; decalcifying the brewer regularly is crucial for optimal performance.
Inspect the spray head for blockages. Ensure the decanter is properly positioned and not cracked, as damaged decanters can disrupt the brewing process. If issues persist, contact Bunn-O-Matic support for expert troubleshooting.
Decanter Handling and Care
