Peter Chang, Hong Kong palace, Hunan gate, tnr, in that order

Bosch dishwasher. It's so compact that I couldn't even figure out where to unscrew the first screw. Now that I've watched the repair man do it, I can try by myself next time. Good thing too, because the error message came up again just now on the dishwasher

Thanks! They do look good. How does one get a Fleck system installed, through a local vendor? I'm DIY but not for water main related work.

I'm not sure if it's sediment or scale. It's grey crusty gunk.
