I have a bosch dishwasher that appears to be working but stuff on top
shelf does not appear to be washed correctly.The water does not appear
to be getting to the top sprayers aswell as it used to.

The pressure is less to the top shelf anyway, so faults tend to appear
there first. Can you be sure that the water flow is worse, as it is
generally lower in any case?

Take the spinner arm off the top (you HAVE been cleaning it regularly,
haven't you?) and make sure that if you run water into the centre, it
comes out of the holes.

Could just be gunged up anyway...run some dishwasher cleaner through it,
maybe more than once (I do it monthly).

Lastly, if you use salt...has it run low? Or the hardness selection
lever been moved?

I had poor cleaning on the top - found that the spinner did not spin, so
plenty of water but only in a couple of places.

Had a Neff with the same problem, and they use a diverter valve which
alternates the top and bottom spray bars. When I called an engineer he
said the problem was down to lack of water level and put some
dishwasher cleaner in which did nothing. I spoke to a Neff engineer
and he said the diverter valve was probably faulty ( I had replaced
the dishwasher by then). It could be similar with a Bosch.

I had the same and I do run cleaning liquid through mine regularly.
The answer is:

add a couple of 3mm holes, one at each end of the arm, on opposing sides
about an inch back from the ends, to produce extra side jets to add spin.

Aim to put the holes in to encourage the arms to spin in the usual
direction, not the opposite to normal.

Worked for me.

Some dishwashers allow the top shelf to be on one of 2 levels. The top
sprayer is fed by a pipe with 2 branches where there are valves so that
water doesn't pour out of the unused feed. If this is the case, make sure
the valve is seating firmly and no offending article is keeping it open.

Mmm - not sure about this - it isn't fixing the problem in fact it could
make it worse by diminishing the pressure of water projected upwards. The
objective is not just to rotate the bar - but to squirt lots of water
upwards. Letting more water out horizontally will reduce the amount
available for spraying upwards.

Could it be a worn pump - giving a reduced pressure (Impeller blades
eroded)? However, I favour the diverter valve problem - has it been set on
'lower basket only?

Incidentally, on a machine I had it was possible to fit the top bar upside
down for use if you always did half loads. Does this apply?

What is the cause of dishwashers needing cleaning - I have not cleaned one
on 20 years of owning them. Except for wiping the area at the bottom of the
door seal. However, I clean the filter several time a week. Is it down to
water hardness?

Grease build-up (I don't have control over what is on the plates....);
that, and general gunge in the pipes.

Once a month I clean all the filters, wipe and clean the entire door
seal area, and run some dishwasher cleaner through it. Eight years old
and all it's needed so far is a new filter (old one fell apart) and a
new drain hose.

Nah - the volume of water from the side jets is a fairly small fraction of
the total. As I said, it worked for me.

I don;t think that was the problem for me. My dishwasher was only a couple
of years old when it developed the problem. Having run it briefly with the
door interlock defeated (and getting wet, expectedly) it seemed to me that
there was a lot of water escaping from the rotor arm bearing. Looking
closer at the bearing, I think it a design fault leading to both an
increase in friction and a decrease in the ability of the bearing not to
**** water everywhere (which reduces pressure to the arm).

Incidentally, on a machine I had it was possible to fit the top bar upside
down for use if you always did half loads. Does this apply?

Mine's got a water block matrix to recover heat from the expelled water back
into the incoming fresh water and the pathways are tortuous and prone to
trapping grease. For some reason, despite dishwasher power being fairly
vicious stuff, it still leaves gunk which cleaner liquid is able to remove.
Don't ask me why...

I have cleaned iit out still no joy .Tightned up th etop spinning arm
by putting in a 1/32 ptfe washer to make up for wear and wobble.

If I put a extra 2 pints of water by hand into the dishwasher whilst
it is operating it works .

Good test - I didn't try that...

Is there a level switch or sensor i should look at

Have a look he

http://www.bshappliancecare.com/

They have exploded parts diagrams for Bosch which should help you to see.
I've used them to source spares for my dishwasher and tumble dryer - they
are very reliable IME.

Did you check the position of the salt selection lever?

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember saying
something like:

Not sure about your Bosch model, but on my Hotpoint there's a level
float switch behind the left side panel. I found the microswitch arm on
mine to be sticking and needed to be bent slightly. Also check the float
pivot for wear.

Sorry to butt in here, but I have missed most of this thread, and don't know
what the exact problem is with the machine.

The main question seems to have gone missing in all the snips and cuts.

Could someone reiterate the fault being seen on this machine, please.

Many thanks
