Comparison Franke A600 and WMF 1500s

Two of the most sought-after professional coffee machines on the Dutch business market go head to head here: the Franke A600 and the WMF 1500S. Both are fully automatic and built for offices, hotels and hospitality settings where anywhere from dozens to hundreds of employees drink coffee every day. The Franke comes from Switzerland, the WMF from Germany — two manufacturers with an excellent reputation for reliability and coffee quality.

Even so, these are clearly different machines, each with its own technologies, strengths and emphases. In this article we compare them point by point on the criteria that matter most in practice: capacity, milk foam quality, suitability for oat milk, grinder type, ease of use and cleaning time.

Differences between Franke A600 and WMF 1500s

Looking at the Franke A600 and the WMF 1500S in detail, it is mainly the emphases that stand out. The Franke A600 puts the focus on the milk experience and easy operation: the FoamMaster™ system and the large, visual touchscreen make it ideally suited to environments with many different users and a broad menu of milk-based drinks. The WMF 1500S leans slightly more towards throughput and operational management, with a higher daily capacity, two usable grinders and the CoffeeConnect platform for remote monitoring.

So the difference is not so much about ‘better or worse’, but about the situation: how many people drink coffee, how varied are their preferences, and does the emphasis lie on the coffee and milk experience or rather on speed and management? Both machines come in several configurations, with the milk system and cleaning often offered as options. The chosen configuration ultimately determines a large part of the performance.

1. Daily capacity

For any business environment, the coffee machine’s daily output capacity is a crucial factor. Nobody wants colleagues queuing up or the machine reaching its limit halfway through the morning.

Franke A600: up to 150–170 cups per day

The Franke A600 has an official maximum capacity of around 150 cups per day (according to DIN 18873), with some sources and configurations reaching 170 cups. This makes the A600 an excellent fit for medium-sized organisations and offices with roughly 20 to 50 employees. The dual outlet and the fast brewing unit ensure a smooth throughput, but the machine is not designed for a structurally higher volume.

WMF 1500S: up to approximately 180 cups per day

The WMF 1500S is designed for medium-sized to larger locations and has a recommended daily capacity of around 180 cups. The dual outlet makes it possible to prepare two drinks at once, which helps during peak hours. Combined with two grinders, the grinding capacity keeps pace with demand, even under more intensive use.

With a recommended capacity of around 180 cups per day versus 150–170 for the Franke A600, the WMF 1500S comes out ahead on this point for busier locations. The difference is not huge, but it is relevant for organisations that consistently operate near the upper limit.

2. Quality and capacity of milk foam

For many business coffee machine users, milk foam is the defining factor. From the cappuccino at the team meeting to the latte macchiato for a client conversation: the quality of the foam largely determines the experience.

Franke A600: FoamMaster™

For many business coffee machine users, milk foam is the defining factor. From the cappuccino during a team meeting to the latte macchiato for a client conversation: the quality of the foam largely determines the experience. The Franke A600 with FoamMaster™ offers full control over the texture, temperature and consistency of the milk foam — from light and airy for a classic cappuccino to dense and creamy for latte art. The A600 produces both hot and cold milk foam, and the foam settings can be saved per drink. FoamMaster has been regarded for years as one of the leading milk systems for fully automatic machines. Note: FoamMaster is an optional configuration; the basic version has a simpler milk system.

WMF 1500S: Dynamic Milk

With the Dynamic Milk system, the WMF 1500S is a formidable contender in this area. The system produces four different consistencies of hot milk foam and three variations of cold milk foam, plus hot and cold milk. This covers virtually the same spectrum as the Franke, including the cold foam specialities that are growing in popularity. Like FoamMaster, Dynamic Milk is an optional configuration.

3. The best machine for oat milk

Plant-based milk, and oat milk in particular, has become a fixture in the modern workplace. More and more employees are choosing lactose-free or more sustainable alternatives. The question is: how do both machines handle it?

The challenge of oat milk

Oat milk contains relatively little protein and more carbohydrates than cow’s milk, which means it foams less stably than whole milk. In addition, oat milk contains sediment; shaking it well before use is essential. If the milk is too thick due to sediment, the system may splatter and the foam quality drops.

Franke A600 and oat milk

The Franke A600 with FoamMaster™ has an advantage here because the foam consistency and temperature can be set individually per drink, making it easier to tune to the properties of oat milk. Franke explicitly positions the A600 as suitable for both dairy and plant-based alternatives, and the cold foam option fits cold oat milk applications.

WMF 1500S and oat milk

The WMF 1500S is compatible with various types of milk and, thanks to the multiple foam consistencies of Dynamic Milk, can also handle plant-based milk. The system is not specifically optimised for oat milk, but the choice of hot and cold consistencies provides room in practice to find an acceptable result.

Practical advice applies to both machines: always use the barista variant of oat milk, shake the carton well before use and make sure the milk is chilled (2–5 degrees Celsius).

4. The type of grinder

The quality of the grinder largely determines flavour development in the coffee. A consistent, accurate grind is the foundation for a good espresso and all drinks based on it.

Franke A600: ceramic grinder, second grinder optional

The Franke A600 comes as standard with one ceramic disc grinder; a second grinder is available as an optional extension. Ceramic has the major advantage of not heating up during grinding, so the coffee beans retain their aroma optimally. In addition, the A600 offers a choice of different brewing units, allowing the machine to be tuned for espresso, regular coffee or larger volumes.

WMF 1500S: two durable grinders

The WMF 1500S can be equipped with two grinders and is therefore set up as standard for two types of beans — for example a regular blend and a decaffeinated variant. WMF uses robust grinding discs built for intensive, long-term use. With Dynamic Coffee Assist, the machine automatically adjusts the grind setting and dosage for a consistent result in espresso-based drinks.

5. Ease of operation

In a business environment, the coffee machine deals with multiple users a day, from people with little technical affinity to coffee lovers who want to fine-tune things themselves. Intuitive operation is then essential.

Franke A600: 8″ touchscreen with visual menus

The Franke A600 has an 8-inch touchscreen with customisable user interfaces and visual images per drink type. This makes operation particularly accessible, including for less experienced users and in self-service environments. The machine offers several operating modes — attended, self-service or a combination — and LED signalling for warnings and notifications. Via Franke Digital Services, the machine can be monitored remotely.

WMF 1500S: up to 10″ touchscreen with CoffeeConnect

The WMF 1500S works with a large touchscreen (up to 10 inches in the S+ version) and the intuitive MMI interface, on which dozens of specialities and even corporate presentations or advertising can be displayed. A strong point is WMF CoffeeConnect: a platform that collects and analyses machine data, allowing facility managers to track consumption and plan service remotely — useful with multiple machines or locations.

6. Daily and weekly cleaning times

Cleaning is often an underestimated but crucial aspect for business coffee machines. Machines that take a long time to clean or require a lot of manual work become a burden for employees and regularly result in maintenance backlogs.

Franke A600: CleanMaster™

The Franke A600 with CleanMaster™ has a fully automated cleaning cycle. At the end of the day, the user inserts a cleaning cartridge or tablet and starts the programme; the machine does the rest. The drip tray and the coffee grounds container are emptied and cleaned daily and are dishwasher-safe. Weekly cleaning mainly consists of a more thorough cleaning of the removable parts, taking 10 to 15 minutes in practice.

WMF 1500S: WMF AutoClean

With the optional AutoClean system, the WMF 1500S can likewise be cleaned fully automatically. The cleaning granulate sits inside the machine and is dosed automatically; it only needs to be refilled after about 60 cleaning cycles, and the cleaning fluid for the milk system after roughly 40 cycles. The milk hose can be rinsed automatically every day during refilling. The cleaning cycle is set once, after which the machine cleans itself at the chosen time.

Conclusion: which machine suits your office?

Both machines are excellent choices for business use and make high-quality coffee. They are also remarkably evenly matched: the differences lie in the emphases, not in a clear winner. The choice therefore depends on the specific needs of your organisation.

Choose the Franke A600 if…

…the emphasis lies on the milk experience and a low threshold for self-service. The FoamMaster™ technology, the visual 8″ touchscreen, the better tuning for oat milk and the easy CleanMaster™ cleaning make the A600 ideal for organisations with a broad menu of milk-based drinks and many different or inexperienced users.

Choose the WMF 1500S if…

…throughput, grinding flexibility and remote management are the priority. The higher daily capacity (around 180 cups), the two usable grinders, Dynamic Milk with a wide foam selection and the CoffeeConnect platform make the 1500S strong for busier locations and organisations that want to monitor multiple machines centrally.

Finally: both machines can be connected to a fixed water supply (the WMF also works on a water tank if desired), offer fully automatic cleaning and a dual outlet, and come from European manufacturers with an excellent reputation for reliability. A trial period or an on-site demonstration is always advisable before you make a final choice.
