Miele Washing Machine PWM 927 [EL DV DD SOM] – 27 kg, 3 AC 400V 50 HZ, Stainless steel

Twenty-seven kilograms rated load at a 1:9 load ratio on a 240 l drum makes the PWM 927 a bulk-capacity machine for a shipboard or offshore laundry. A spin speed of 1,100 rpm with a g factor of 541 brings residual moisture down to 46% with cold rinse, 41% with hot rinse, and 10% when processing cleaning cloths, so dryers downstream do less work per cycle.

On board, the electrical and structural data frame where this washer can be installed. It is specified for a 3 AC 400V 60 HZ electrical connection with a heater rating of 24 kW, a total connected load of 25.6 kW and a 50 A fuse rating, so it needs a suitably sized distribution panel and cabling. Net weight is 650 kg and the maximum floor load is 9,072 N, figures a naval architect can check against deck scantlings before the position is fixed. Heat dissipation into the room is 4.7 MJ/h and the emission sound pressure level is 73 dB(A) re 20 µPa, important where the laundry sits under accommodation or shares space with other technical systems.

Water and energy consumption are documented for standard and ECO profiles with both cold and hot water connections. With a cold water connection the standard programme uses 201 l, 5.9 kW and runs for 57 minutes; with a hot connection this changes to 197.9 l, 1.61 kW and 47 minutes. In ECO, cold water operation is quoted at 193.5 l, 4.48 kW and 42 minutes, while ECO with hot water uses 190.2 l, 0.58 kW and runs for 34 minutes. The Mops standard 60 °C programme draws 322.2 l with a cold connection and 323.4 l with a hot connection, with running times of 57 and 48 minutes respectively. Specific consumptions of 7.4 l/kg and 0.22 kWh/kg on a cold connection and 7.3 l/kg and 0.06 kWh/kg on a hot connection make it straightforward to project daily water and power demand from the wash schedule.

Durability is specified at 30,000 tested operating hours. The Benchmark series front loader stands 1,646 mm high, 1,090 mm wide and 1,226 mm deep; gross dimensions are 1,793 × 1,365 × 1,425 mm with a gross weight of 707 kg, which matters when routing the unit through hatches and along corridors. The stainless-steel front and control panel house the M Touch Pro Plus control system, which is freely programmable. The door opening is 415 mm in diameter with a 180° opening angle on a right-hand hinge, giving full access for mixed loads up to 620 cloths at 22 g, 142 cotton mops at 40 cm / 190 g, 19 respirator masks or 4 summer horse blankets.

Water connection capacity is generous: four cold water inlets at 1/2" with 3/4" unions, two hot water inlets at 1/2" with 3/4" unions and two optional hard water connections at 1/2" with 3/4" unions. That lets the installer separate potable, hot and hard process water in line with the vessel’s system design.

This washer is the right choice where a laundry genuinely needs 27 kg capacity, high mop and cloth throughput and documented hygiene performance on a 3 AC 400V 60 HZ supply. It is the wrong choice for a small crew-only laundry that cannot support a 25.6 kW connected load, a 9,072 N floor load or the 1,090 × 1,226 mm footprint. Ordered under Miele designation PWM 927 [EL DV DD SOM], article number 51927006SOM and material number 12887740.
