Miele Washing Machine PWM 507 [EL DP MAR 1N AC 230 V 60Hz] – 7 kg, 230 V, Lotus white

7 kg capacity on a 64 l drum at 1,600 rpm with a g-factor of 704 gives the PWM 507 its core character: a compact Little Giants washer that spins hard and dries fast. Programme time on a cold-water connection is 69 minutes; with combined hot and cold feed that drops to 59 minutes, which matters in a ship’s laundry where turnaround drives the number of machines specified.

The electrical connection is 230V~ with a total connected load of 2.85 kW and a 2.65 kW heater rating, fused at 16 A. That makes this machine viable on smaller onboard distribution boards that cannot spare a heavy three-phase circuit, while still delivering tested hygiene performance on thermal disinfection programmes. Heat dissipation is quoted at 1 MJ/h and the emission sound pressure level is ≤70 dB(A) re 20 µPa, so the impact on a small, enclosed laundry in both HVAC load and noise can be quantified early in the design.

Specific water consumption is 7 l/kg on a cold-water connection and 6.6 l/kg on a hot-water connection, with total draws of 49 l and 46 l per full load respectively. Specific energy is 0.14 kWh/kg on cold and 0.06 kWh/kg on hot, with total programme consumptions of 0.98 kW and 0.44 kW. Residual moisture comes out at 48% with a cold rinse and 45% with a hot rinse, which, combined with the high spin factor of 704, shortens dryer run times and cuts energy use downstream.

Externally, the machine stands 850 mm high, 605 mm wide and 714 mm deep, with gross transport dimensions of 944 × 660 × 768 mm. Net weight is 98 kg, gross 102 kg, and the maximum floor load is 2,820 N, giving the naval architect a clear figure for the deck loading calculation. The door opening is 300 mm in diameter with a 167° opening angle and a right-hand hinge, so access for loading bulky items is predictable even in a tight utility space. Heat dissipation of 1 MJ/h helps frame the ventilation requirement alongside other dryers and ironers in the same room.

The PWM 507 carries one cold and one hot water connection, each specified as 1 × 1/2" hose with 3/4" threaded union, and uses a DN 22 drain pump. That combination simplifies connection to the ship’s potable hot and cold ring mains and allows the hot feed to be used to cut both programme duration and electrical energy consumption where recoverable heat is available. Tested operating hours are quoted at 30,000, which frames service life expectations in a commercial marine duty cycle.

Build and control

This unit fits a vessel that needs a compact, hygienically specified 7 kg washer on a single-phase 230V~ supply, with verified virucidal efficacy and Lloyd’s Register approval backing the shipboard installation. It is not the right choice where individual loads routinely exceed 7 kg or where a steam-heated, larger-capacity Benchmark machine would align better with an existing plant room.
