PROBABLE CAUSE

 

REMEDY

Brew cycle will not start (cont.)

8. Control board or dispense valve

If the switch panel is operating prop-

 

 

 

 

erly, proceed as follows. Attach a

 

 

 

 

voltmeter to the terminals of the

 

 

 

 

dispense solenoid. Connect the

 

 

 

 

brewer to the power source. Turn

 

 

 

 

on the brewer and press the BREW

 

 

 

 

switch. Voltage should be present

 

 

 

 

at the solenoid terminals. If voltage

 

 

 

 

is not present, refer to the wiring

 

 

 

 

diagrams and check the wiring har-

 

 

 

 

ness. If voltage is present, check for

 

 

 

 

continuity across the terminals of

 

 

 

 

the solenoid coil. If continuity is not

 

 

 

 

present, replace the solenoid (See

 

 

 

 

page 24). If continuity is present,

 

 

 

 

the valve may be stuck closed.

watch or second hand, time the

 

 

 

 

length of the brew cycle. Record

 

 

 

 

this time inside the top lid. If service

 

 

 

 

is ever needed again, use the time

 

 

 

 

as reference to determine if time

 

 

 

 

has changed.

 

 

2. Lime build up

Inspect the dispense valve and

 

 

 

 

sprayhead for excessive lime de-

 

 

 

 

posits. Delime as required.

 

 

3. Dispense Valve

Remove dispense valve and clear

 

 

 

 

any obstructions. Rebuild or re-

 

 

 

 

place valve if necessary. (See page

CDBC TC, CDBC APS, CDBCF TC, CDBCF APS specifications

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. They cater perfectly to coffee enthusiasts and business owners looking for reliable brewing solutions that deliver consistent quality and taste. With the Bunn CDBCF series, coffee brewing becomes not only an art but also an efficient and seamless process.
