If you have an Asko W640 or W660 front loader that’s acting flakey, one of the first things you’ll want to do is put it into diagnostic mode. This will let you test various functions such as the drain pump and drive motor and other sensors and functions in the machine. You won’t find this in your owner’s manual though they really should include it. What possible harm could it do? But the Samurai’s gotcha covered. Go git ’em!
