BREWING CIRCUIT

 

 

PROBLEM

 

PROBABLE CAUSE

Brew cycle will not start

 

1. Display flashing

2. No water

3. No power or incorrect voltage to the brewer

4. ON/OFF switch not in the "ON" position

5. Low water temperature (Brew lockout is enabled)

6. Water not touching refill probe inside tank

7. Switch panel

REMEDY

Brewer has shut down due to mal- function (See Diagnostic Chart in manual, Page 20, or under top lid of brewer).

Water lines and valves to the brewer must be open.

Check for voltage across the termi- nals at the terminal block.

The indicator lamp must be lit

Allow brewer to heat until ready lamp is lit, or disable the brew lock- out feature. (See page 8 & 9)

Press ON/OFF switch (indicator must be lit). Brewer will refill until water touches probe inside tank. Water must be in contact with refill probe before brew cycle will start.

Disconnect the brewer from the power source. Disconnect the rib- bon connector from the control board. Check for continuity between pins 1 & 2 (An arrow on the connec- tor indicates pin 1). No continuity should be present. Press the BREW switch. Continuity should be present for as long as the switch is held down. If no continuity is present, replace the switch membrane de- cal. (See page 23)

The Bunn CDBCF series of coffee brewers is an essential tool for any coffee business, renowned for its reliability and efficiency. This series offers different models including the CDBCF APS (Automatic Pour-Over) and CDBCF TC (thermo carafe), among others. Each of these brewers is designed to produce exceptional quality coffee while ensuring ease of use.

One of the main features of the Bunn CDBCF APS is its automatic pour-over capability, which ensures that water is heated to the perfect brewing temperature and dispensed consistently. This model is equipped with a stainless steel water tank that maintains optimal water temperature, resulting in flavorful coffee extraction. Furthermore, the APS model allows for quick brewing cycles, producing up to 3.8 gallons of coffee per hour, making it ideal for high-demand environments.

The CDBCF TC model, on the other hand, utilizes a thermal carafe to keep coffee hot for extended periods without the need for a hot plate. This technology not only preserves the coffee’s flavors and aromas but also minimizes energy consumption. The thermal carafe can hold up to 1.9 liters of brewed coffee, making it efficient for serving in busy settings.

Both models in the CDBCF series come with a simple interface for straightforward programming and operation. Features such as the BrewLOGIC technology help regulate the brewing time and monitor water flow to ensure consistency. This is particularly beneficial in maintaining the quality of coffee across multiple brewing batches.

In terms of build quality, Bunn CDBCF brewers are constructed with durable materials designed to withstand the wear and tear of daily use in busy coffee shops. Their compact design requires minimal counter space while providing a high volume of output.

Overall, the Bunn CDBCF APS and TC models stand out for their advanced brewing technologies, versatility, and user-friendly design.
