Default Dishwasher rinse problem

Our dishwasher (a Baumatic) is failing to rinse properly, it may be
failing to do other things properly as well but the rinsing is the
obvious problem.

The symptom is dirty rinse water left in the dips in the bottoms of
mugs etc. when the wash has finished, and also slightly 'not quite
clear' glasses. The basic removal of dirt seems to be working OK
still, it's just that the rinse isn't clean.

The only other thing I've noticed is that it seems to 'retry' starting
up the main pump/wash motor sometimes. For example I ran a 'rinse
only' cycle recently to see how it went and the pump seemed to try
starting several times (with a momentary sound of splashing water
etc.) before it actually started running continuously.

Does anyone have any ideas what the problem might be?

I've checked for blockages as far as I can and have cleaned all the
filters very thoroughly.

Hi

Our Bosch was problematic when I first installed it in what sounds like
similar ways. Fine, gritty debris; slightly unclean look to glasses;
slightly strained sound to emptying.

After speaking with the tech line I was pointed towards ensuring there
was the stated 'head' between the low and high points of the evacuation
tube. I'd had this kind of trailing from low point on DW to point
where it joined waste pipes.

I think 60cm was required. Once I'd got this in place using a bit of
string and hook to lift it up all was well.

Hmmmm. I am wondering how much crud / dirty water is getting left
behind. If it's a lot (most of what you would expect to have come off
the dishes) then yes there is probably a problem but I have noticed that
some food cause this to happen with ours. High starch food (beans and
pulses) don't seem to be dissolved by the dishwasher powder. That causes
a fine coating of starch to be left on the outside of the glasses
leaving them dull we also get small grains of starch left in any dips.
We wondered if the dishwasher was broken the first couple of times it
happened until it click what was going on. Just rinse the plates and
pans that have had high starch food in them before putting them in. We
found rinse aid helped a little (mostly to brighten up the glasses) but
you still end up with the starch in the dips. The best way is to just
avoid putting it in in the first place.

Ditto for our Bosch except that the symptoms only started recently. It
was cured by a really through clean of *everything* - one of those little
bottles of cleaner which you stick in the cutlery rack and run a wash on;
all filters removed and cleaned; both rotors out and checked for gunge and
blockages; cover of sump unscrewed and bits of crud (which had got past
the filters) removed from there-under.

Also cured the non-auto-dispensing rinse-aid auto-dispenser whose outlet
was clogged with soap granules etc.

Don't know which of the above did the trick, but it's now fine!

Our dishwasher (Ariston) used to start deposting "crud" on glasses etc when
the salt reservoir ran low and/or the water hardness setting on the softener
was set too low. Phone up your water company ask for the hardness, set dial
on dishwasher accordingly, fill reservoir with salt, run empty as most
dishwashers regenerate the softener at the end of their cycle. Much improved
after doing that.

Also had the waste pump fail (replacement for 8 off Ebay) and before it
failed completely used to give "dirty" washes as I assume it was not pumping
the waste dirty water away sufficiently.

Anyway new pump in conjuntion with whole house water softener, I don't
bother rinsing the plates etc just pile it all in and crystal sparkling
clean wash every time.
