Electrolux Professional Undercounter Dishwasher 502715 – Undercounter, atmospheric boiler, double skin, drain pump, det&rinse aid disp,USPH,540d/h-60Hz-Mar

Thirty baskets per hour at 18 dishes each gives the 502715 a published throughput of 540 dishes per hour. It does that with just 2.5 litres of fresh water per cycle, held in an atmospheric boiler sized at 12 litres.

For a ship’s galley this combination matters more than the headline basket rate. The machine is built for a 440 V/3 ph/60 Hz supply, so it drops straight onto a standard marine board without transformers, and the 6.85 kW default installed power is modest enough to fit into a tight electrical balance. Rinse water draw at 2.5 litres per cycle is a fixed cost against the vessel’s fresh water production, and the 0.5–7 bar inlet pressure window means the warewash station does not depend on a perfectly stable hydrophore set.

The wash chamber takes 500 × 500 mm baskets with 335 mm usable height, enough for a mix of plates and small utensils on a crew or officers’ mess without going to a hood machine. External dimensions of 600 × 615 × 820 mm let it sit under a standard counter run, while the double-skin insulated construction and 61 dBA noise level keep heat and sound spill down in a confined pantry or scullery. The washing tank holds 23 litres at a wash temperature of 68 °C, and the boiler elements rated at 6 kW lift the incoming 50 °C supply up to a final rinse in the 80–90 °C band controlled by the atmospheric boiler.

Cycle structure is straightforward: programmable cycle times of 120, 180 or 240 seconds, selected to match soil level and service pattern. The wash pump is rated at 0.736 kW to move the tank volume through the basket, while a separate 2 kW tank heating element maintains the 68 °C wash temperature. Inlet water can sit anywhere between 0.5 and 7 bar (7–102 psi) and still meet the machine’s operating window, and the 20.5 mm drain line size is small enough to tie into a galley waste run without special fittings, subject to the yard’s drainage design.

This is the right choice where the requirement is a compact undercounter machine dedicated to one or two small stations, with around 540 dishes per hour and limited space and power. It is the wrong part for a main galley wash-up that runs continuous racks from multiple outlets; that duty calls for a hood-type or rack conveyor line at higher throughput and with separate pre-wash.
