Have been trying to work out why our dishwasher is no longer cleaning
properly (a 5-yr-old Bosch built-in; can't find a model number).
Basically, stuff on the top rack, and sometimes on the bottom one,
invariably comes out with gritty residue stuck all over it. Things I've
tried out/checked:

- Ensured spray holes in rotor arms aren't blocked;
- Cleaned filter in bottom of machine;
- Opened door mid-cycle to check rotor arms move (but can't tell how
vigourously though)
- Changed detergent (we're in a soft water area so no need for softener)

During the wash, water reaches the upper rotor via a flat grey conduit
attached to the inside of the machine, and which mates up at the back of
the upper rack with an aperture leading to the upper rotor; I'm guessing
that for whatever reason not enough water is getting through? How can I
tell?

One thing I've noticed is that after a cycle, if you lift the filter the
water in the machine's sump is really mucky; is that normal or should it
be basically clean 'rinse' water down there?

Any advice much appreciated!

Only thing you can do is start it and open the door when it's working
on a wash.

That way you can see if the top impeller is working and the amount of
water in the top.

It's not as dramatic as it sounds, but put a towel on the floor at the
sides and wear some sort of eye guard.
