Magister Stella ES Dual Boiler Espresso Machine

Magister Stella ES Dual Boiler Espresso Machine

The company Magister is relatively new to the espresso industry, starting back in 1997. We started business with them in 2012, bringing in the Stilo line. These were HX machines serviceable in both the home and commercial environments. As our customers became more familiar with the Magister line, the interest in a dual boiler espresso machine started to grow. After years of R&D, they released the Stella line.

Their decision to use copper boilers is one we like.Having a rotary vane pump instead of a vibration pump is always a plus, whether hooking your machine up to a water line or not. The less rattling, the more enjoyable pulling a shot is.

Magister also released a semi-automatic version of the Stella without the electronic touchpad. This gives space above the E61 grouphead to allow for a flow control kit to be installed. However, since the grouphead is lower on the front panel, most of the flow control knobs won’t be able to turn freely.

Dual Boiler System:

• Copper, insulated:  The boilers are made of copper, which retains heat better than stainless steel. Typically, copper boilers are more susceptible to limescale when compared to stainless steel boilers. Therefore, we highly recommend using a water softener. The manufacturer wraps the boiler with insulation for maximum heat retention.
• Pull a shot & steam milk at the same time: Steam is always readily available at the turn of a knob. Hence, there is no wait time going from coffee to steam mode.
• Auto-shutoff: A sensor detects the water level in the boiler. When below the threshold, the heating element shuts off to prevent it from burning out.

Electronic Controls:

• A row of 5 buttons just above the grouphead for pulling your espresso shot. The first four are programmable and the last one is for your manual start/stop shot pulling.

4-Key OLED Display:

• Electronic controls: A set of programmable espresso dispensing options along with a manual start & stop option. For the programmable options, the total amount of water (mL) that it is preset for will show on the display.
• Boiler temperature: Adjust the temperature of both the coffee and steam boilers when active and when in ECO mode.
• Boiler priority: You can set the refill and heat up priority to either the coffee or steam boiler first.
• C --> F: Can switch between Celsius and Fahrenheit.
• Shot timer (Chrono function): Visible on display when pulling a shot.
• Counters: Give you a sense how much you use the machine.
• Maintenance schedule: Optional setting for when to “clean” your machine or change your water softener based on shot count.
• ECO mode: Machine will go into a low power level mode after a preset time (up to 30 min).

E61 Grouphead:

• Consistent heating: Hot water circulates from the boiler through the grouphead and back to keep the grouphead and your portafilter nice and hot. This keeps the grouphead at a constant, stable temperature compared to other groupheads that have a built-in heating element.

Dual Pressure Gauge:

• Left side measures bar pressure when pulling a shot of espresso.
• Right side measures steam pressure. Optimal pressure is around 1.6 bar.

Cool Touch Steam / Hot Water Wand:

• Rotary knobs: Allows you to control the power of steam / hot water dispensed.

Rotary Vane Pump:

• Quiet operation: Rotary pumps are necessary for direct connect capable machines since vibration pumps cannot handle the incoming water pressure. The main benefit that you will experience is that they are a lot quieter.

Switchable between water tank and direct water connection:

• Large water tank: The larger the tank, the less downtime in refilling.
• Water line connection: Easily switchable through the PID controls. Stainless steel hose & fitting are included.

Parts / Accessories Included:

• Portafilters: Single spout & dual spout. Both 58mm in diameter.
• Filter baskets: 1-cup, 2-cup, and blind for backflushing.
• Tamper: Simple 2-sided plastic.
• Scoop: Simple plastic one for ground coffee.
• Water line connection: Stainless steel braided hose & fitting.

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?
