Single Boiler Dual Use System

A single boiler handles both brewing espresso and steaming milk, offering a streamlined, space-saving design that’s cost-effective and easy to maintain. By switching between brew and steam modes, it’s ideal for home baristas preparing drinks one at a time, delivering solid temperature performance without the added complexity of heat exchange or dual boiler systems.

E61 Grouphead

Features the classic E61 grouphead design with a 58mm commercial portafilter interface, known for its thermal stability and consistent extraction. The thermosyphon circulation system keeps the grouphead continuously heated with circulating water, helping maintain stable brewing temperatures shot after shot. Its mechanical lever operation provides a smooth, reliable feel while allowing a brief pre-infusion phase that gently wets the coffee puck before full pressure is applied, improving extraction balance and flavor clarity. Widely used across premium espresso machines, the E61 platform is valued for its proven performance, serviceability, and compatibility with standard 58mm accessories, making it easy to upgrade or maintain over time.

PID Display

The integrated OLED PID display provides precise electronic temperature control for consistent brewing and steaming performance. Users can easily adjust key settings such as brew temperature, steam boiler temperature, and standby/eco modes directly through the interface, allowing for accurate dialing-in across different coffee beans and roast profiles. The system continuously monitors and regulates boiler temperature in real time, minimizing fluctuations for more stable extractions.

Next to the display, LED indicator lights provide clear machine status at a glance, including when the heating element is active and when the water reservoir is empty, helping prevent dry running and ensuring safe operation. The combination of OLED clarity and intuitive controls gives users both precision and confidence, making it easier to manage performance while maintaining optimal brewing conditions.

Removable Drip Tray

The removable drip tray is designed for easy cleaning and everyday convenience, pulling out smoothly for quick emptying and rinsing. Made from durable molded plastic, it is built for regular use while helping keep the workspace clean and organized by collecting excess water and espresso runoff. A built-in red indicator float rises above the drip tray grill when the tray is nearing capacity, providing a clear visual alert that it needs to be emptied before overflow occurs. This simple, reliable feature helps maintain cleanliness during busy service and reduces the risk of spills. The lightweight design makes routine maintenance fast and hassle-free in both home and commercial environments.

Customizable Side Panels

The VBM Domobar Single Boiler includes stainless steel panels by default, with optional color panels available separately to personalize the machine’s look. The magnetic attachment system makes swapping panels quick and tool-free, allowing owners to easily refresh or customize their espresso setup.

Vibration Pump

The VBM Domobar Single Boiler uses a vibration pump to deliver the pressure needed for espresso extraction in a compact and reliable design. Compared to larger commercial rotary pumps, vibration pumps help keep the machine more affordable and space-efficient while still producing excellent espresso at home.

Tank/Reservoir System

The removable water tank features an open-top design that makes refilling and cleaning quick and convenient. The wide opening provides easy access for adding water, rinsing the reservoir, and maintaining better overall hygiene with less effort.

Steam Wand w/ Rotary Knob

The commercial-style steam wand is operated by a rotary control knob for smooth and precise steam adjustment. This design gives users better control over steaming pressure for creating silky milk texture and latte art while offering a familiar café-style workflow.

General Espresso Machine Notes/Warnings:

• Upon first use (tank/reservoir models): On the initial start-up (or after a long period of non-use), it is important to make sure the pump is removing water from the tank. When the machine is powered on, you will hear the pump running. After 5 seconds, squeeze the in-line hose in the tank (usually the longest hose, has a particle filter attached). if you hear a different sound, this means the pump is working correctly. If not, immediately power down the machine and contact us. For more information, visit this page General Manual Pump Priming.
• Electrical: To avoid electrical damage to this espresso machine which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. Without the recommended surge suppressor, the espresso machine can be damaged at the power switch, the electronics, the heating element, the pressurstat, or the wiring inside. For more information, visit this page Power Protection.
• Water: To increase the useful life and not damage your espresso machine, please use softened water. Softened water is water without calcium and magnesium, but still has other minerals for espresso extraction. Do not use distilled, purified, or reverse osmosis water as these types of water create oxidation with the metals and cause the same damaging effects as limescale. For more information, visit this page Water Choice.
• Descaling: We do not recommend descaling unless there is an issue with the espresso machine. Too much descaling can eat away at the metals and gaskets inside an espresso machine. As a preventative measure, we recommend using softened water as explained in the bullet point above.
• Backflushing: This procedure of cleaning the grouphead will need to be performed from time to time. For more information, visit this page Espresso Machine Backflush – Why 50?
