Miele Washing Machine PWM 909 [EL DP DD SOM] – 9 kg, 3 AC 440V 60HZ, Stainless steel

Nine kilograms at a 1:9 load ratio in an 80 litre drum is the design point of the Miele PWM 909 in the Benchmark Performance Plus range. At 1300 rpm with a g‑factor of 518 it is specified to leave 47% residual moisture on a cold rinse and 44% on a hot rinse, so downstream drying time can be planned from published figures.

This front loader has a stainless steel front and control panel and is specified and approved for shipboard use as well as specified for offshore installations. That aligns with laundry spaces in steel hulls where vibration and movement are normal operating conditions. Automatic door lock, the ability to add laundry mid‑cycle and a remaining cycle time display suit a crew environment where work breaks around watch patterns and machines are shared.

Utility data fixes the impact on the vessel. Electrical connection is 3 AC 400V 60 HZ with electric heating, a heater rating of 5 kW and a total connected load of 5.25 kW on a 16 A fuse rating. One cold and one hot water inlet are provided, each as 1x 1/2" hose with 3/4" threaded union, and discharge runs through a DN 22 drain pump. On a standard cold water connection the PWM 909 uses 56.2 litres and 1.2 kW over a 49 minute programme; with cold and hot water it uses 59.3 litres and 0.23 kW over 45 minutes. Specific consumption is 6.3 l/kg and 0.13 kWh/kg on cold, and 6.6 l/kg and 0.03 kWh/kg on hot, so water‑maker output and generator loading can be budgeted directly.

The ECO programme trims those numbers where time allows. With a cold water connection it uses 49.7 litres and 0.82 kW over 34 minutes, and with cold and hot water connected it uses 52 litres and 0.14 kW over 32 minutes. Heat dissipation into the room is 2.3 MJ/h and the emission sound pressure level is 65 dB(A) re 20 µPa, both important where the laundry shares an HVAC zone or bulkhead with accommodation or technical spaces. Tested operating hours are 30000 and the recycling rate is stated at 96%, which will matter for operators reporting lifecycle performance.

Externally the machine measures 1020 × 700 × 718 mm (H × W × D), with gross transport dimensions of 1214 × 750 × 817 mm. Net weight is 146 kg, gross weight 158 kg, and maximum floor load 2480 N, figures a naval architect can drop into deck loading checks. The door opening is 370 mm in diameter, opens through 180 degrees on a right‑hand hinge, and the capacity examples in the spec cover items from 2 summer horse blankets to 204 cloths at 22 g and 42 cotton mops at 40 cm / 190 g.

Build and control

• Front loader from the Benchmark series, Performance Plus range with stainless steel front and control panel
• M Touch Pro Plus control system, freely programmable with remaining cycle time display
• Automatic door lock with the option to add laundry mid‑cycle
• Maintenance‑free synchronous motor and heavy‑duty electric heater element with 5 kW rating
• Detergent drawer with 3 compartments, detergent empty sensor and DN 22 drain pump
• EcoSpeed wash rhythm for reduced water use and continuous wash temperature monitoring
• Three-dimensional imbalance monitoring for controlled 1300 rpm spin at g‑factor 518
• Thermal disinfection rinse programme and continuous wash temperature monitoring for hygiene
• Specified for offshore installations and specified and approved for shipboard use; tested for 30000 operating hours with a 96% recycling rate

This unit fits vessels that want a 9 kg Benchmark Performance Plus washer on a 3 AC 400V 60 HZ supply with both cold and hot water available and spin performance tight enough to plan dryer loading. It is the wrong choice where only a different supply configuration is available or where the laundry concept is built around much larger batches than a 9 kg drum can process.
