WMF 1100 S

325 mm wide, 500 mm high, 571 mm deep: the WMF 1100 S is engineered for office kitchens and reception desks that cannot accommodate large-group machines. Net weight per official brochure is approx. 25.5 kg; depending on configuration variant, the operating manual specifies 24–28 kg.

For installation, the planning guidance recommends at least 50 mm clearance on each side, 60 mm to the rear, 200 mm overhead, and 800 mm work space in front. These clearances are prerequisites for air circulation and service access; falling short risks overheating and difficult maintenance. A fixed water connection is optional; without installation, the unit operates on the integrated 4.5 l water tank.

The 7-inch touchscreen supports vertical swiping between beverage favourites and is designed for unattended self-service operation. SteamJet warms cups with steam, which is noticeable for hot drinks in porcelain cups. The cup tray accommodates cups up to 100 mm height.

Bean hoppers are available in two sizes: the standard holds 550 g beans or 700 g powder; the extended holds 1,100 g beans or 2,200 g powder. For offices with peak-time demand, the larger hopper significantly reduces refill frequency. Which configuration is available must be specified in the quotation; dealers market different packages under the same model name.

Note on depth: the current brochure states 571 mm, while the operating manual and planning information cite 561 mm. For tight installation, verify the depth with the dealer using the order number.

The removable brewing unit processes a maximum of 15 g coffee grounds per brew and can be withdrawn without tools. This simplifies daily cleaning and makes user-led maintenance realistic. The construction mirrors that of the 1000-S line and is documented as serviceable through WMF authorised dealers.

The Basic Milk system draws milk via tube from an external cooler, a separate milk container, or a milk carton (operating manual pages 34–35, manufacturer specification). Compared to machines with integrated refrigeration, this requires more space discipline and hygiene attention: the tube must be cleaned daily and replaced every 6 months at the latest. Those requiring integrated cooling must step up to the WMF 1500 S or 5000 S.

The 7-inch touchscreen displays beverage favourites with symbols; vertical swiping reveals additional options. A display lock is configurable for publicly accessible areas.

The rear USB slot supports multiple functions: import and export of recipes and beverage symbols, export of counters and HACCP protocols, data backup, and firmware updates. An optional Bluetooth stick plugs into this slot; the function must be enabled via software (operating manual page 80, manufacturer specification).

WMF CoffeeConnect is available as an optional telemetry platform. It connects machines, delivers machine data, and is stated to support process optimisation per the official brochure. Pricing and scope are negotiated on a project basis; no public price list exists.

80 cups daily: WMF cites this figure as both the recommended daily output and maximum hourly output (manufacturer specification, brochure page 8). For offices with 20 to 40 employees and average consumption of 2 cups per person per day, the machine is adequate. Above 50 regular users or with pronounced peak demand—for example, 30 servings within 30 minutes—capacity becomes the limiting factor.

The 4.5 l water tank yields approximately 32 cups at 140 ml portions before refilling is required, if no fixed water connection is installed. For offices with more than 20 users, the fixed-water option is the more practical solution; installation effort is minimal in most office kitchens.

The grounds container holds coffee grounds from approximately 30 brews per the operating manual. During peak times, it may need emptying up to three times daily when the daily maximum is reached.

Standard beverage range: espresso, café crème, cappuccino, milky coffee, latte macchiato, milk foam, and hot water. The optional powder dispenser adds hot chocolate. The brochure references up to 8 beverage favourites on the display.

The system cleaning cycle lasts approximately 10 minutes per the operating manual. Required are a WMF cleaning tablet (1.3 g) and a catch container with at least 3 l capacity. The machine prompts cleaning every 200 brews or every 6 days at the latest; after 250 brews or 7 days without cleaning, it locks operation entirely. System cleaning is therefore not optional.

The milk system must be cleaned daily after use. The milk frother and steam nozzle are cleaned manually after the system cleaning cycle. The milk tube must be replaced as needed, at the latest every 6 months (manufacturer specification, operating manual pages 34–35). Operators who do not document this schedule risk hygiene deficiencies. For HACCP-regulated operations, a written maintenance log is advisable.

The descaling programme lasts approximately 60 minutes. The operating manual describes two 0.75 l bottles of liquid descaler; the current WMF shop stocks 0.7 l bottles (€7.63 net). The exact container size should be clarified with WMF before proceeding. The descaling interval depends on water hardness, throughput, and the filter system employed.

Safety-relevant components must be inspected every 24 months without prior display prompt and replaced if necessary. This inspection requires a WMF service technician or an authorised workshop; the date should be actively maintained in the maintenance calendar.

Rated power 1.9–2.3 kW at 220–240 V, 50/60 Hz, 1/N/PE: this figure derives from the operating manual, planning information, and official brochure. The range reflects configuration and heating load variability. WMF does not publish a separate standby power figure for the 1100 S; Eco Mode reduces steam boiler temperature and thus energy demand, but no exact standby wattage is publicly specified.

OFFICE ROXX measured approximately 75 dB(A) during grinding near the machine. The operating manual specifies a permissible continuous sound pressure level below 70 dB(A); the deviation reflects measurement position and grinder load. For office spaces requiring quiet near the machine, grinding noise is a consideration; 2–3 metres distance to the nearest workstation is recommended.

Extraction times per OFFICE ROXX editorial test on a warmed machine: approximately 38 seconds for 140 ml café crème, roughly 25 seconds for espresso or cappuccino. Cold start to first coffee: 5 minutes 12 seconds. Eco Mode extends the next milk drink by approximately 15 seconds of heat-up time; black drinks remain available immediately.

Permissible water supply pressure: 2 to 6 bar at a minimum flow of 2 l/min; maximum inlet temperature 35 °C. Outside these boundaries, pressure damage or insufficient extraction quality may occur. The permissible ambient operating range is +5 to +35 °C at a maximum of 80 per cent relative humidity without condensation.

New units range from €3,495.00 net (ZVN, office configuration with 1 grinder, Basic Milk, and water tank) to €4,873.11 net (Kaffee Online Kaufen, twin-topping configuration with extended bean hopper). The spread of approximately €1,378 reflects differing configurations. For a direct price comparison, identical order numbers must be matched.

WMF designates the 1100 S as discontinued; it is orderable only until 30.09.2026. New orders must be placed before this deadline, and production slots must be confirmed in advance. WMF has not publicly stated how long spare parts will remain available after production ends; enquiry with the manufacturer before purchase decision is recommended.

Consumables per the WMF online shop (all prices net): cleaning tablets 1.3 g, 100-pack €19.48 = approx. €0.19 per tablet and cleaning cycle. Speciality milk cleaning liquid, 1 litre: approx. €12.75.
