Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Who knows the 20 year thing is exxagerated, but they don't attack that. On ISE's website you can see the life expectancy is 8,000 cycles. They don't say Miele is exxarating their 10,000. From a marketing point of view it is interesting that they claim less cycles than their most important competitor.
 
Hot and cold fill is a waste of time on a modern machine because the hot water never reaches the machine before it stops filling.

Secondly cold water is great for stain removal and detergents work better from cold.

I've owned countless machines and have never had a moldy door seal or funky dispenser. Providing you do at least one 60 deg wash with a bio powder and leave the door open, your machine should be in ship shape.

I have to say that i've seen some really shocking black mouldy cold fill only machines in my time but less has to be said for a lot more older hot & cold fill machines. Using the boil wash programme often does keep the door seal looking ok but that doesn't clean the soap dispenser & housing out.
 
To make a couple of points.

Regarding cold fill only DW's and washers.  All DW's  Here in the USA are hot fill and our washers have both valves.  Part of this is that we have 120/60/1  power which would cause insanely long heating times if the washers or DW's filled cold for a hot cycle.  European machines run on 220-240/50/1 and can heat faster.  Our Washers are mostly TL and do not have heaters and need water from the water heater for a warm or hot wash.  Also most American homes have a 40 gallon or larger water heater which can provide for all domestic needs including laundry.

On the commercial side most laundries have boilers which provide plenty of 60C plus water and steam for laundering all fabrics as well as pressing them after cleaning.

In the dishroom our dishmachines fill from the water heaters and boost the temp for sanitizing using tank elements and booster heaters.  These machines and their boosters use 208-240/60/1-or3 better is 460-480/60/3.

Alas some of our homes in the US have circulating pumps on our hot water systems. This keeps the water in our pipes hot all the time. It basically takes about 5 to 10 seconds to have steaming hot water coming out of our faucets, so there is really no lag time when you start the washer and it is filling immediately with hot water, no matter how little water the washer uses.

Yes, it depends on one's individual installation. All the houses I lived in had recirc pumps and a big water storage tank so hot water was always plentiful. My washer is in the basement, which is excluded from the circulation circuit. Still, it only takes two to five liters for the hot water to come through - if I don't purge the line. The dishwasher is on cold water as it needs (or prefers) cold water for the condensation drying cycle. But even with cold water coming in, the dishwasher takes it to steaming hot within ten minutes.
 
@retro-man:

I would estimate that the percentage of the U.S. population that has domestic hot water recirc is almost zero.

If you have a hot water heating system where the domestic hot water comes from the heating boiler, then the efficiency penalty from adding a recirc pump to the DHW system is small, since the system is really inefficient in the first place.

But a bunch of other people don't have that kind of system.
