I believe that some European dishwashers are made to hook up to cold
water since in some areas they often have smaller hot water supplies.

that because europeans often have tankless water heaters.

my old bosch had a fantastic water heater built in.

unfortunately the bocsch was the least reliable of any dishwaser I
have ever had and dead last in reabilty by consumer reports.

now that isnt the worst its parts cost a fortune, all service is
difficult, because of the design, and it breaks way too much,

thats why mine went to the trash.

I am going to insulate the hot water lines to improve performance of
the whirlpool dishwasher. its just one year old and honestly a piece
of scrap. heck even the silverware basket broke.

too bad its hard to find good products anymore

the chinese guys are good at producing low priced stuff, but quality
isnt one of their concerns
