Need help?Do you have a question about the Gaggia SUP 049EU and is the answer not in the manual?
This document describes the Gaggia Cadorna coffee machine, a range of espresso machines designed for home use. The manual covers various models including SUP049EU, SUP049EP, SUP049E, and SUP049, providing detailed technical specifications, operating logic, maintenance procedures, and disassembly instructions.
The Gaggia Cadorna coffee machine is designed to prepare a variety of coffee and milk-based beverages. It features an integrated coffee grinder, a brewing unit, and a pump system to deliver coffee, hot water, and steam. Depending on the model, it can offer manual, semi-automatic (cappuccinatore), or automatic (carafe, Pinless Wonder system) milk frothing capabilities. The machine includes a display for user interaction, allowing selection of different coffee strengths and beverage types. It also incorporates sensors for water level detection, coffee bean absence, and brew unit position to ensure optimal operation and user safety.
The Gaggia Cadorna operates on a 230V~50Hz power supply with a maximum power consumption of 1900W. During the heating phase, it draws approximately 5.6A. Key components include a stainless steel boiler, which heats water for coffee, hot water, and steam dispensing. Safety is ensured by two thermostats set at 190°C. Temperature monitoring is handled by an NTC (Negative Temperature Coefficient) variable resistor sensor that transmits values to the electronic control board.
The machine features a direct current motor with flat ceramic grinder blades for coffee grinding, with grinding times ranging from 8 to 10 seconds. The pump is an Ulka Type EP5/FMGW 230V, 50 Hz, capable of delivering approximately 13-15 bar of pressure. An overpressure valve opens at approximately 16-18 bar.
Water circuit filling takes about 15 seconds maximum for the first filling cycle, and heating time is approximately 45 seconds. The auto shut-off time is consumer-settable. The adjustable spout height varies by model: 115-160 mm for SUP049E, SUP049EP, SUP049EU, and 75-120 mm for SUP049.
The housing material is thermoplastic. Dimensions vary slightly by model: 260 x 385 x 400 mm for SUP049E, SUP049EP, SUP049EU, and 260 x 345 x 400 mm for SUP049. Weights range from 10.5 kg (SUP049) to 12.0 kg (SUP049EU). The power cord length is 1200 mm.
The water tank has a capacity of 1.5 litres and is removable. It can accommodate a Brita Filter (12NC-996530010484 for EUR-ASIA / 12NC-996530010528 for US-CAN). The coffee bean hopper capacity is 300g, and the coffee grounds drawer can hold 10 pucks. Milk carafe capacity is 0.6L for SUP049EU and 0.5L for SUP049EP. Energy saving mode consumption is less than 1 Wh.
The machine offers various pre-programmed coffee types with default quantities: Ristretto (30 +/- 10% ml), Espresso (40 +/- 10% ml), Espresso lungo (80 +/- 10% ml), Caffè (120 +/- 15% ml), Americano (40 +/- 10% ml coffee, 110 +/- 15% ml water), Cortado (40 +/- 10% ml coffee, 30 +/- 10% ml milk), Cafè au lait (90 +/- 10% ml coffee, 90 +/- 10% ml milk), Flat white (80 +/- 10% ml coffee, 80 +/- 10% ml milk), Cappuccino (40 +/- 10% ml coffee, 120 +/- 15% ml milk), Cappuccino XL (70 +/- 10% ml coffee, 180 +/- 20% ml milk), Latte macchiato (40 +/- 10% ml coffee, 240 +/- 20% ml milk), Latte macchiato XL (50 +/- 10% ml coffee, 300 +/- 20% ml milk), Froth milk (180 +/- 20% ml milk), and Hot water (150 +/- 20% ml).
The Gaggia Cadorna features a user-friendly display with multifunction buttons, an on/off button, "my favourites" button, "home" button, "clean/setting" button, and "start/stop" button. The operating logic includes a single microswitch gear motor that repositions the brew unit for standby and dispensing. The temperature sensor (NTC type) ensures precise temperature control for optimal brewing.
The autodose system adjusts grinding time based on current consumption, ensuring consistent coffee strength. The machine can detect coffee bean absence or a blocked grinder, displaying error codes (e.g., Error 01 for blocked grinder, Error 02 for disconnected grinder). The coffee cycle involves grinding, brewing unit movement, preliminary dispensing, solenoid valve operation (for milk products), coffee dispensing, and gear motor return to home position.
For milk-based beverages, the Pinless Wonder system heats milk with steam, mixes it with air for frothing, and refines the texture in an emulsion chamber. The water tank includes a capacitative sensor for water level detection, triggering a "Water low" message when the reserve is reached.
The machine also features a descaling request system based on flow meter pulses and water hardness settings (1 to 4, with 4 being very hard). It prompts a "Change water filter" message after a specified amount of water has flowed through.
The manual provides detailed instructions for maintenance, including specific tools and maintenance products. Recommended products include thermal paste, descaler ("ACC SAE DECALCIFIER 5 L 1 UNIT"), grease ("PARALIQ GB 363"), and silicone grease ("ACC TUBE FIN FOOD GREASE 2 400 ML").
Safety warnings emphasize the importance of using personal safety devices, disconnecting the appliance from power before repair, and performing dielectric strength tests after repair. Technicians are advised to be cautious of hot and pressurized parts during disassembly.
Key maintenance procedures include:
The manual also outlines a machine repair flow, from intake and diagnosis to repair, functional testing, safety checks, and documentation, ensuring a structured approach to service.
