My dishwasher has of late, but wherefore I know not, lost all it's,

thinking some part of the grot-filtering must be amiss, and perhaps
the top shelf pipe dips deeper in the the grot-sump than the bottom
shelf pipe.But the bit at the bottom where the water goes is all
screwed together with torx screws and looks a bit scary. Does anyone
have any suggestions? I don't want a flood or a broken dishwasher.

Usually happens when the arms are not free to rotate - blocked with
bits of bone or even grease. Do they turn freely, and are their
driving jets free of all bits.

You could, as a last resort, do what we did at Hoover to check machine
operation, which was to fashion a perpex door to allow us to view what
went on inside.
