WMF 1500 S+

325 mm wide, 716 mm high, 590 mm deep: the WMF 1500 S+ is designed for counters and service areas in office kitchens, canteens, and hotel restaurants. Empty weight ranges from 32 to 36 kg depending on configuration; a second person is advisable for initial installation. The housing follows the commercial WMF design line with straight lines, rounded edges, and matte metallic finish.

Centrally positioned on the front is the colour 10-inch touchscreen display. It displays graphical beverage buttons as well as all settings access points. Administrators can configure visible beverage buttons, assign access permissions, and divide the machine into user profiles. Those managing different cost centres can enable or disable beverage categories separately.

Bean hoppers are located on top of the machine: left and right, approximately 1,100 g each; an optional centre hopper approximately 700 g. An optional lockable powder hopper holds approximately 2,000 g for instant coffee or cocoa. Locking reduces unauthorised access in shared areas.

Minimum clearances according to the operating manual: 50 mm on the sides and rear for ventilation and accessibility; at least 200 mm clearance above the bean hoppers for filling. The installation surface should be at least 850 mm above floor level; the work area in front of the machine at least 800 mm. These requirements are readily achievable in typical office kitchens and canteens.

Dynamic Milk is the technological centrepiece of this product line. The system produces four different hot milk foam consistencies, three cold milk foam variations, as well as hot and cold milk without modification or system changeover (manufacturer specification, brochure p. 2, not independently verified in field testing). In combination with the optional 2-milk solution, two milk types or plant-based alternatives can be offered simultaneously. For offices with growing demand for oat milk cappuccino, this is direct added value.

Dynamic Coffee Assist monitors brew flow in real time and automatically corrects grind size and coffee quantity for deviations (manufacturer specification, brochure p. 4). Bean variety changes or humidity fluctuations require manual adjustments at the grinder less frequently.

CoffeeConnect is included as standard according to the current WMF brochure. The platform transmits beverage counters, fill levels, cleaning status, and error codes to a web-based dashboard. For fleet operators with multiple machines, this enables central overview without on-site inspection. Connection is via Wi-Fi; a wired LAN option is not mentioned in published documentation.

AutoClean is available as an option. The system automatically dispenses cleaning agent for coffee and milk systems and starts the cleaning cycle on command or automatically in the evening. For locations with changing service staff, this is a relevant operational advantage.

Additional optional expansions: Cup Sensor (three modes: dispensing lock without cup, automatic outlet positioning, size-dependent beverage display), Fresh Filtered Coffee (filters espresso and café crème of oils and sediments), syrup station (up to four syrups, fruit purées, or spirits with three dosage quantities each). These options must be configured at order time and cannot be retrofitted later without a technician.

180 cups daily is WMF's manufacturer specification. This figure applies with continuous use without cleaning pauses, thus under conditions that rarely occur in office operation. In typical office rhythms with morning peak (7 to 9 a.m.) and post-lunch demand spike (12 to 2 p.m.), 80 to 130 cups daily is the realistic planning figure. This difference is not a machine deficiency, but rather the natural result of operational pauses, cleaning intervals, and demand curves.

For an office with 100 employees and consumption of 1.2 to 1.5 cups per person daily, this totals 120 to 150 cups. The 1500 S+ covers this demand comfortably without capacity constraints. Only at 200 persons with 1.5 cups daily, totalling 300 cups, would a WMF 5000 S+ or a second machine be more suitable.

The bean hoppers left and right hold approximately 1,100 g each; the optional centre hopper approximately 700 g. At 8 to 10 g coffee grounds per dispensing and 100 cups daily, one fill suffices for a full operating day without refilling. With intensive breakfast periods of 50 dispensings in quick succession, reserve remains in the afternoon.

The operator chooses the water supply: the 4.5-litre tank covers approximately 30 to 40 water-intensive dispensings before refilling is required. With mains connection, this step is permanently eliminated. For carbonate hardness above 5 °dKH, the operating manual requires an upstream WMF water filter 200 (EUR 26.50 net).

Approximately 5 minutes daily: this summarises cleaning requirements with AutoClean enabled. The cleaning cycle starts automatically in the evening or on command, automatically dispenses cleaning agent and takes approximately 2 to 3 minutes. Staff must empty the drip tray and grounds container and wipe the milk outlet externally.

Without AutoClean, daily effort increases significantly: the milk system must be manually sanitised after the last milk beverage of the day. The HACCP cleaning procedure prescribes this. The operating manual contains a dedicated HACCP chapter; the protocol can be exported via USB, which is relevant for quality documentation in hospital or industrial kitchen environments.

Weekly maintenance adds 15 minutes: Remove milk tubing and soak in cleaning solution for 10 to 15 minutes (no tools required), wipe the brew group shaft, check powder hopper for residual moisture.

Descaling intervals depend on water hardness. The machine displays descaling requirement on screen. With hard tap water and no filtration, this may occur after approximately 3 months; with WMF water filter and soft water, 6 months or longer may pass between cycles. The process runs automatically after insertion of WMF liquid descaler (0.7-litre bottle, EUR 7.63 net).

Rated power: 2.75 to 3.25 kW according to the operating manual (print page 129), 2.75 to 3.5 kW according to current brochure. The differing upper limit is not explained in published documentation. For circuit protection planning: use the higher figure (3.5 kW). A Schuko socket with 16 A circuit breaker is sufficient; a dedicated circuit for the machine is recommended for this power class.

Continuous sound pressure level at the workplace is below 70 dB(A) according to the operating manual. Normal conversation is approximately 60 dB(A); a quiet office approximately 40 dB(A). The machine is thus acoustically acceptable in busy office environments, restaurant areas, and canteens. Grinding noise during dispensing is barely noticeable in typical ambient noise.

Eco mode: 10 minutes after the last beverage dispensing, the machine automatically lowers the steam boiler temperature. Automatic shutdown can be set to 30, 60, 90, 120, 150, or 180 minutes, which is adaptable to individual office opening hours. From the lowered eco mode, milk beverages require approximately 15 seconds warm-up time.

WMF does not provide an absolute standby consumption figure in any public document. No energy label for this machine was found in researched sources. For precise annual consumption, socket measurement during actual operation is recommended.

Water connection: flow pressure must be between 2 and 6 bar (measured at 2 l/min). For values above 6 bar, a pressure reducer must be installed upstream according to the operating manual. For mains water and carbonate hardness above 5 °dKH, a WMF water filter 200 is mandated.
