Miele Dishwasher PFD 409 [WB Offshore] – 3 AC 220V 60HZ, Stainless steel

Fourteen minutes for the shortest programme and a stated 152 plates per hour define the working pace of the PFD 409 [WB Offshore] in a shipboard pantry or officers’ mess. Cleaning performance is also given as 8 baskets per hour, so its duty can be tied directly to table turns and shift patterns.

With 2 levels in a 598 x 598 mm footprint and a required niche width of 600 mm, the unit is dimensioned to drop into a standard under-counter bay. External height with lid is 835 mm, with a maximum height adjustment of 60 mm, which allows alignment to surrounding worktops while keeping an in-feed height of 216 mm. Inside the cabinet, 520 mm usable height and 530 mm width, with 474 mm depth in the upper basket and 505 mm in the lower basket, set clear limits for plate diameter, glass height and basket choice so there is no trial-and-error at commissioning.

Heat dissipation into the room is quoted at 1.44 MJ/h. In a small enclosed pantry or servery that figure goes straight into the HVAC calculation instead of relying on a generic allowance. Sound pressure at the workplace is 45 dB(A) with a sound power level of 57 dB(A) re 1 pW, which matters where the dishwasher shares space with seating or a service counter and background noise is constrained.

Electrically, the unit runs on AC 220V 60HZ with a total connected load of 2.7 kW and a 2.3 kW heater rating on a 16 A fuse. That allows it to sit on lighter accommodation or pantry circuits rather than a heavy galley board, provided the 1.9 m mains connection cable and the niche constraints are respected. For vessels standardised on AC 220V 60HZ this is a direct specification, not an onboard adaptation.

Water-side data is explicit. The PFD 409 [WB Offshore] uses 17.5 litres per wash cycle from a single cold water connection, with required flow pressure between 1 and 10 bar. Maximum water hardness is 10.7 mmol/l, so the need for softening on bunkered water can be checked against that limit. The circulation pump is rated at 390 l/min, supporting the independently tested virucidal efficacy and verified hygiene performance within the 14 minute programme. A drain pump to DN 22 with a maximum pump head of 100 cm from floor level defines how the waste line must be routed before any extra sump or pump is specified. The water inlet and drain hoses are each 150 cm long, typically enough to reach adjacent services inside a 600 mm bay.

In day-to-day use, the M Touch Flex control system, 7 dishwashing programmes and a maximum delay start of 24 h give the crew control over timing and programme choice, including the Universal programme for normally soiled load items. Service life is specified at 28000 wash cycles, which lets a superintendent relate expected years in service to planned cycles per day on a given deployment. Emissions data and WiFi capability, where available by region, support integration into monitored accommodation or mess areas.

Build and control

• Stainless steel front, lid and side panels with galvanised rear panel
• M Touch Flex control system with 7 dishwashing programmes
• Universal programme for normally soiled items
• Max. delay start of 24 h for scheduled or off-peak running
• Independently tested virucidal efficacy
• Verified hygiene performance
• WiFi connectivity (availability of digital products may vary by region)

This offshore variant suits cabins, small galleys and pantries that need defined hygiene performance on an AC 220V 60HZ supply and can work within 8 baskets per hour and 17.5 litres per cycle. It is the wrong choice for a central wash-up area that has to move substantially more ware per hour or handle large GN traffic, where a larger warewash line should be specified.
