Miele Washing Machine PWM 909 [EL DP DD SOM] – 9 kg, 3 AC 230V 60HZ, Stainless steel

Nine kilograms at a 1:9 load ratio in an 80 l drum places the Miele PWM 909 in the compact Benchmark Performance Plus class. A spin speed of 1300 rpm with a g factor of 518 and residual moisture values of 47% with a cold rinse and 44% with a hot rinse mean loads leave the drum dry enough for controlled downstream drying.

This variant is specified and approved for shipboard use and specified for offshore installations, so the marine role is explicit rather than adapted. Electrical supply is 3 AC 230V 60HZ with a total connected load of 8.2 kW, a 7.95 kW heater rating and a 20 A fuse rating, giving firm numbers for the laundry sub‑board. Heat dissipation into the room is 2.3 MJ/h and the emission sound pressure level is 66 dB(A) re 20 µPa, both important in compact laundries where HVAC capacity and noise limits are tight.

Water and energy figures are detailed enough to model against the fresh‑water plant and hotel load. With a cold‑water connection the PWM 909 uses 6.3 l/kg, or 56.2 l per standard programme, with 1.2 kW energy consumption and a 49 minute programme duration. On a hot‑water connection it reports 6.6 l/kg, 59.3 l total, 0.23 kW energy consumption and a 45 minute duration. The ECO programme cuts the cold‑water draw to 49.7 l with 0.82 energy consumption and a 34 minute duration, or 52 l, 0.14 energy and 32 minutes on a combined cold and hot water connection. Those combinations let the operator decide whether to lean on electrical power or available hot water where waste‑heat recovery is part of the plant.

On the hygiene side, the PWM 909 carries a thermal disinfection rinse programme with continuous wash temperature monitoring. EcoSpeed wash rhythm is specified for reduced water use without losing mechanical action. Tested operating hours are 30000, which lets planners align replacement with overhaul cycles instead of guessing service life from light‑duty equipment. The control system is M Touch Pro Plus, freely programmable, with a three‑compartment detergent drawer so ship‑specific programmes and dosing regimes can be implemented.

Physically, this front loader has a stainless steel front and stainless steel control panel. External dimensions of 1020 x 700 x 718 mm (H x W x D) and a net weight of 140 kg determine how it moves through doors and passageways; gross dimensions of 1214 x 750 x 817 mm and a gross weight of 152 kg define the crated envelope for logistics. Maximum floor load is 2421 N, a figure the naval architect can check directly against deck scantlings. The door opening of 370 mm, a 180 degree door opening angle and a right‑hand hinge set how linen trolleys will approach the machine in a confined laundry. A quoted recycling rate of 96% supports end‑of‑life planning under corporate environmental reporting. The published loading examples translate the 9 kg rating into real items, including 4 respirator masks, 2 helmets, 1 overalls and 2 over jackets, or cleaning textiles such as 204 cloths at 22 g and 42 cotton mops at 40 cm / 190 g.

This unit suits vessels and offshore facilities that need a 9 kg Benchmark Performance Plus washer with documented marine approval and precise water, energy, heat and noise figures. It is the wrong choice where the laundry concept is built on much larger batch sizes per cycle, because the 80 l drum and 9 kg rating will force multiple runs where a larger Benchmark body would clear the work in fewer loads.
