Finding a home espresso machine that balances professional pressure, user-friendly controls, and a compact footprint can be challenging. The LERTIN EM626 aims to deliver a complete coffee experience with a 20-bar pressure system, a built-in milk frother, and a clear display that shows brewing time and water temperature. This analysis examines the specifications, features, and practical considerations of this semi-automatic espresso maker to help you decide if it fits your home brewing needs.
📊 Quick Specifications Table
✨ Key Features
High Definition Display with Real-Time Feedback
One of the standout aspects of this display is the integrated high-definition screen that shows the real-time water temperature and brewing time. This allows you to monitor the extraction process at a glance, which is helpful for understanding how your coffee is being prepared. The display also supports a user-defined capacity setting, letting you program a custom volume for larger cups or personal preferences.
20 Bar Professional Pressure System
The machine utilizes a 20-bar pressure system designed to extract coffee grounds thoroughly. High pressure helps produce a richer, more mellow flavor by forcing water through the coffee at the optimal rate. This system also supports cold extraction: by adding ice water to the tank and using the Americano button without preheating, you can prepare cold brew-style coffee directly from the machine.
PID Constant Temperature Control
Temperature stability is critical for consistent espresso. The EM626 features a PID thermostat system set to 198°F, which aims to maintain the correct temperature throughout the extraction. The machine also includes a cup warming function—placing your cup on top during preheating helps maintain coffee temperature and reduces flavor loss. An automatic shut-off activates after 30 minutes of inactivity to save energy.
Dual Function Steam Wand
The steam wand serves two purposes: frothing milk and dispensing hot water. It produces dense, glossy milk foam for cappuccinos and lattes. The wand has a rubberized insulating sleeve for safety, and the nozzle is 360° adjustable and removable for easy cleaning. For hot water, you can turn the knob to hot water mode to dispense hot water for Americanos or tea.
57.5 oz Removable Water Tank
The large 1.7-liter water tank allows you to brew multiple cups without frequent refills. It is transparent and removable, making filling and cleaning straightforward. The stainless steel drip tray is also removable and features a red buoy indicator that warns when the water level is rising, helping you avoid overflow.
🎨 Design and Build Considerations
The machine features a compact stainless steel exterior that measures 5 inches deep, 11.4 inches wide, and 11 inches high. The stainless steel construction is described as durable, wear-resistant, and corrosion-resistant, which should help maintain the machine’s appearance over time. The compact footprint makes it suitable for smaller countertops, and the design is intended to be portable enough for outdoor camping or travel. The included portafilter is a 51mm, 3-ear stainless steel bottom model, and it comes with both single and double-layer filter baskets. A tamper with a spoon is also included in the box.
⚡ Performance Expectations
Based on the confirmed specifications, the LERTIN EM626 is a semi-automatic espresso machine that requires you to grind and dose your own coffee. The 1200-watt boiler provides fast preheating, with the manufacturer stating a 16-second warm-up time. The 20-bar pressure system should produce a good crema with properly ground coffee. The PID temperature control aims to keep the water at 198°F for consistent extraction. The steam wand can produce microfoam for latte art, and the hot water function adds versatility. For cold brew, the machine can extract cold coffee without preheating, though the manufacturer advises ensuring the boiler is cool before starting this process. Performance will ultimately depend on your coffee grind size, tamping technique, and water quality.

🆚 Comparison with Similar Products
In the semi-automatic espresso machine category, the LERTIN EM626 competes with other compact models that offer similar pressure and steam wand features. Many entry-level machines provide 15-bar pressure, while this model offers 20 bar, which may appeal to those seeking higher extraction potential. The inclusion of a high-definition display with temperature and time readouts is a differentiating factor, as many machines in this price range rely on simple indicator lights. The dual-function steam wand that also dispenses hot water adds convenience, though some machines offer separate hot water spouts. The 57.5 oz water tank is larger than many compact models, reducing the need for frequent refills. Buyers looking for a fully automatic experience may prefer super-automatic machines, but the EM626 offers more control for those who enjoy the process of dialing in their espresso.

🛒 Buying Guide
When considering the LERTIN EM626, think about your coffee preferences and daily routine. If you enjoy experimenting with grind size, dose, and tamping pressure, a semi-automatic machine gives you that control. The display helps you track extraction time and temperature, which is useful for learning and consistency. The steam wand is ideal if you regularly make milk-based drinks like lattes or cappuccinos. The cold brew function is a bonus if you enjoy cold coffee without the acidity of traditional hot brewing. The compact size makes it suitable for small kitchens, dorms, or even travel. However, if you prefer a fully automated process with a built-in grinder, you may want to consider a super-automatic model. Also, ensure you have a good quality burr grinder to get the most out of the 20-bar pressure system.

❓ Frequently Asked Questions
How do I preheat the machine correctly?
Plug the machine into a rated outlet, turn it on, and rotate the knob to the COFFEE MODE. Press the power button on the control panel to start preheating. Wait until all indicator light rings stop flashing and remain on, which signals that preheating is complete. The knob must be in the Coffee position; if it is in the Hot Water or Steam position, the indicator lights will keep flashing and the machine will not work.
Can I make cold brew with this espresso machine?
Yes. To make cold brew, do not turn on the power switch for preheating after plugging in. Directly press the Americano button, and the machine will perform a cold extraction. When you reach the desired capacity, press the power button to stop. Ensure the boiler is in a cool state before starting, and do not use this function after other hot functions, as the cold extract will not be cold enough.
How do I customize the large cup capacity?
After preheating is complete, press the Americano button to start brewing. When the cup reaches your desired volume, press the Americano button again and wait for the light ring to turn off automatically. The machine will remember this setting and repeat the last dosage on the next use. To clear the custom capacity, press and hold the power button until the display turns off, then wait for the indicator light to stop flashing to restore factory settings.
Why is no water coming out when I press the coffee making button?
Several factors can cause this. First, ensure you have followed the user manual for the first use cycle. Check that the water tank has enough water and is properly seated—remove and reinstall it if necessary. Also, verify that your coffee powder has the correct particle size; using too fine or too coarse grounds can block the flow. Add the proper amount and thickness of coffee powder as recommended.
What are the best tips for making milk froth?
For optimal milk frothing, use chilled whole milk at about 5°C (41°F) and pour 200 ml into a milk tank. Insert the steam wand nozzle about 2-5 mm deep into the milk. Position the steam wand at a proper angle to the milk tank to introduce more air and create bubbles. The steam wand should be touching the liquid in the cup to avoid splashing.
Does the machine have an automatic shut-off feature?
Yes. The machine switches off automatically after 30 minutes of non-working time to save energy. This is a useful safety and energy-saving feature.
🏁 Final Verdict
The LERTIN EM626 is a well-equipped semi-automatic espresso machine that brings professional-grade features to a compact, stainless steel body.
