This page provides essential technical guides and policies for Decent Espresso machines. Key topics include setup instructions for plumbing, drainage, and catering kits, water quality recommendations, repacking procedures, and our stolen machine policy.
Source: How to repack your Decent Espresso machine
To safely transport a Decent Espresso machine for moving, travel, or service, it must be repacked in its original padded suitcase. The process involves cleaning and removing the water tank, drip tray, and portafilter, then disconnecting the tablet.
The machine is placed into the custom foam padding, with accessories like cables and handles organized in designated compartments. By following these specific steps to secure the machine and its components, you ensure the equipment remains protected and organized during transit.
Source: Stolen machine policy
Decent Espresso's Stolen Machine Policy is designed to protect buyers, support legitimate owners, and deter the trade of stolen equipment.
For Prospective Buyers: The company strongly advises requesting a serial number before purchase. Decent's tech support will verify the machine's legitimacy, specifications, and repair history with the registered owner. Reluctance from a seller to provide this number is a major red flag.
Transfer of Ownership: Legitimate second-hand buyers can transfer ownership by providing a photo of the serial number. Remaining warranties are fully transferable, and expired ones can be repurchased.
Theft Deterrence and Recovery: Stolen machines are added to a global database. Once connected to the internet, these units are remotely disabled, rendering them unusable. If a stolen machine is flagged:
Context on Theft: The policy highlights common theft methods, including "porch piracy," courier "loss" (where machines are later auctioned), and recent AI-generated marketplace scams.
Source: DE1 drip tray v2 fittings how-to
This guide explains how to install the fittings for the DE1 Drip Tray V2. Unlike the V1, which featured a molded ceramic drain, the V2 uses a hole in the ceramic base secured with metal parts, washers, and gaskets to create a reliable seal.
The primary advantage of the V2 design is a more secure drain tube installation that doesn't require a cable tie or a perfectly dry surface to prevent slipping. The page includes a video tutorial and a detailed assembly diagram to help users correctly position the washers and gaskets for a leak-free setup.

Water quality is the most critical factor for the longevity of Decent Espresso machines. Using improper water causes scale buildup and heater failures, which are not covered under warranty.

Source: How to connect your Drain Kit to your machine
The Decent Drain Kit v1 allows users to bypass manual emptying by routing wastewater from the drip tray to a container or drainage system. It is compatible with all DE1 models (PRO, XL, and PLUS) but is not compatible with the Bengle.
The kit includes a specialized drip tray with a drainage hole, a cover, a long opaque waste tube, a small straight tube for countersinks, an L-shaped connector for sideways drainage, and a cable tie.
Installation Methods: There are three primary ways to configure the drain based on your setup:
Critical Setup Note: In all configurations, the cable tie must be used to secure the tubing or connector to the drip tray spout to prevent leaks. Additionally, ensure the end of the waste tube is not submerged in water, as this creates backpressure and prevents proper drainage.
Source: How to connect your Catering Kit to the machine
The Decent Catering Kit automates refilling for all DE1 models and the Bengle. Regardless of the option chosen, you must connect the black network cable from the kit to the machine for power and communication.
This is the simplest setup for direct suction from a water source.
Use the included simple valve to manage flow and prevent backflow.
Crucial:* Ensure the arrow on the valve points toward the kit (away from the bottle).
Once switched on (indicated by an orange light), the kit remains on standby. It only activates when the machine detects a need for water, at which point a green light illuminates. To ensure freshness, the kit tops off the tank rather than keeping it permanently full.
Source: How to connect your Plumbing Kit to the machine
The kit allows you to connect any DE1 model and the Bengle machine directly to a pressurized water line, such as a reverse osmosis system.
Installation: A thin hose connects the water source to the inlet on the left side of the device via a pressure regulator. A thicker hose and a black network cable run from the back of the device to the back of the espresso machine. The unit can be placed on the countertop using its rubber feet, screwed down, or mounted directly to the back of the machine.
Operation: Once turned on, the system automatically fills the machine's water tray whenever the machine detects it needs more water. To keep the water fresh, it only refills on demand rather than keeping the reservoir constantly filled to the maximum.
Source: How many coffees can a Decent Espresso machine make per hour?
The DE1XL from Decent Espresso can produce approximately 102 espressos per hour, a conclusion reached by founder John Buckman through a series of "10-minute challenges." The primary takeaway from these tests is that the machine is rarely the bottleneck; instead, speed is determined by the barista's workflow and equipment setup.
Throughout the challenges, several factors limited performance:
For milk drinks, the DE1XL managed 54 lattes per hour when one machine was dedicated to brewing and another to steaming. Even without a flawless performance, the Decent proved capable of outpacing many professional coffee shops. To maximize speed, the study recommends having multiple portafilters ready and starting the next extraction before finishing latte art.
Source: DE1 USB-C adapter documentation
The Decent Espresso USB-C adapter installs between the machine and its Bluetooth module, offering a reliable, wired connection to mitigate wireless interference. Using a compatible USB-C hub allows users to connect both the DE1 and a Half Decent Scale to a single tablet or desktop.
Compatible apps include Streamline-Bridge and Decenza. The adapter prioritizes USB-C; plugging in a cable disables Bluetooth, which automatically restores a minute after unplugging. Crucially, users must unplug the USB-C cable before powering on the machine to prevent it from freezing during boot.
Source: Updating the M50Mini tablet to firmware v1.06
This guide outlines updating the Teclast M50Mini tablet (model TLA016) shipped with newer DE1 machines to firmware version V1.06_20260311. This over-the-air update resolves false-positive antivirus flags by tightening system permissions.
Users should first verify their model, connect to Wi-Fi with at least 30% battery, and optionally back up the de1plus data folder to a computer. The update is executed via the "System Update" app. If the update fails to appear, users can extract their serial number to request access from support.
