Miele Dishwasher PFD 401 U [WB Marine] – 2 AC 240V 60HZ, Stainless steel

Ten minutes for the shortest programme and a rated 228 plates per hour set the duty profile of the PFD 401 U [WB Marine]. With 12 baskets per hour across two loading levels, it is sized for continuous small batches rather than a single large central pot wash.

Externally, the machine stands 820 mm high with a net width of 598 mm and net depth of 580 mm, against a required niche width of 600 mm. That footprint allows it to slide into a standard under-counter bay in a pantry or crew mess without special furniture. The in-feed height of 216 mm above the floor keeps baskets within reach on a moving deck and limits bending for the operator.

For shipboard electrical design the figures are clear: 3 AC 240 V 60 Hz, a total connected load of 5.8 kW and a heater rating of 5.4 kW on a 20 A fuse. The 1.9 m mains connection cable defines how close the isolator and junction box have to sit. A circulation pump capacity of 390 l/min supports the published cleaning performance on both levels, which matters where the same machine has to clear plates from repeated services.

Internally, there is 530 mm usable height and 536 mm usable width in the wash cabinet, with 474 mm depth at the upper basket and 516 mm at the lower basket. That geometry lets the designer check the largest plates and trays on the drawing board instead of at commissioning. The unit is specified with a stainless steel front and galvanised side panels, combining a presentable face towards the servery with a tough carcass inside the counters.

Water demand per cycle is defined: one cold-water connection, 17.5 litres per wash cycle and a required flow pressure between 0.4 and 10 bar. A maximum water hardness of 10.7 mmol/l identifies when softening or other treatment upstream becomes mandatory if the vessel’s water is particularly hard. The water inlet hose is 170 cm long and the drain hose 150 cm, with a drain pump in DN 22 and a maximum pump head of 100 cm above floor level, so the grey-water run can be laid out with confidence. Heat dissipation into the room is quoted as 1.08 MJ/h, a specific input into HVAC calculations for enclosed laundries or pantries.

The control system is M Touch Basic with 10 dishwashing programmes and a maximum delay start of 24 hours, so cycles can be staged outside peak serving times. The maximum final rinse temperature is 70 °C and the machine carries independently tested virucidal efficacy and verified hygiene performance, tying into documented cleaning plans. Service life is stated at 28,000 wash cycles, giving a basis for lifecycle planning. Emissions at the workplace are 47 dB(A) sound pressure and 59 dB(A) sound power, low enough that the machine can sit close to occupied areas without dominating the noise environment. Drying is specified as without, so the process must include rack space and time for drip or air drying once the door is opened.

This unit fits where an under-counter footprint and a rated 228 plates per hour with 12 baskets per hour match the workload of a small galley, crew mess or wardroom. It is the wrong choice where automatic drying after every cycle is a firm requirement, because drying is specified as without and the line has to manage free-draining and air drying.
