The biggest swiss online seller makes charts for warranty claims. Basically: how many warranty claims does each brand have? This chart only shows the most popular brands of coffee machines sold on the site, but I still find it interesting.
i went to look at my local retailers data on filter machines and most moccamasters had a quite good but not perfect rate often around 1-3%, things to keep in mind are that its a local store so there isnt large amount of data so seeing rates of 0% or 10%+ were common but more interesting was the reviews that ultimately indicated that you basically want to get either a moccamaster or WMF, though many of the brands in that list are not sold here so cant comment on them
Guess the simpler mechanics of filter coffee machines do make them a lot more reliable. Wish i could've seen some Japanese brands too, Zorujishi makes a small one that I'm interested in...
Yes, but some of the warranty rates for espressso makers seem unacceptably high. Especially premium products (with premium prices) should not have warranty rates above 5%. 16% is just insane.
