Some thoughts from the “office”. I spent far too much of my time last year researching washers and dryers for our ships (foreign flag Panamax bulkers and Handymax product tankers). Electrical requirements varied by ship, either 220/60/1 or 450/60/3. My goal was to standardize the fleet for all new purchases. Washer capacity requirements were 6-8 kgs. Dryer requirement was to be heated/vented (not condensing).
Miele Professional is very nice. Not the most expensive option, either. But no 450V units.
Speed Queen and Unimac were nice too, but 450V machines were too costly ($7,500+).
Primus not considered due to cost, $7,500+ and poor customer service.
Electrolux (also branded as Asko) is a good product, with 450V machines in $4,500-6,000 range. 220V machines were $3,500-4,500.
Wesco Navy from Hamburg was the winner. 450V machines $4,000-5,000 for our size range. Machines built for ships, in different sizes, and all spare parts sold separately. They offered a 2 year warranty as well (even if installed by the crew). We had these machines on two ships already and knew they were reliable. Made in Germany as well.
Sadly, electronics are not avoidable. I also wanted something most basic as possible. When I realized every machine is going to have a circuit board and display panel, my next thought is which manufacturer would give support to the crew in troubleshooting, and will they sell spare parts. Some require you go back to an authorized dealer. Others have zero troubleshooting input (“we can send a technician”). During my research a control board failed on a 10+ year-old Wesco washer on board one of our ships. I called their office in Hamburg, described the problem, confirmed new board was needed, and had a quote to my email before hanging up. Part in stock, cost EUR 289, would ship next day. Their manuals also show how to make almost any repair, even down to how to disassemble the machines in correct order.
