Dishwasher has not been cleaning well–bits of gunk left on dishes. We've cleaned everything and think that the problem may be that the top arm is not spinning. Any idea of how to get it going again?
I have the same problem. The dishwasher has been working fine since we bought it 5+ years ago but now the top arm is not spinning and the upper dishes are not getting clean.

Only the top rack isnt getting clean? there is a little plastic
circle in the middle of the bottom of the upper spray arm. turn it
counter clock wise to pull the upper spray arm from the upper rack.
make sure that isnt clogged and the spray holes are not clogged.
otherwise....
the piece that the bottem spray arm plugs into and
runs along the back wall of the tank to the top is called a feed tube.
pull the bottom spray arm out. now you can see the part of the feed
tube that feeds the upper spray arm water. does it pop out freely and
easily? if so then you need a new feed tube, if not then its most
likely your not achieving the right water level or your impeller
connected to your circulation pump(motor) is clogged not supplying
enough water pressure to travel up the feed tube to spin the upper
spray arm.
I have a Bosch Dishwasher Model # SHU43C07UC with the top wash arm not spinning. I still have not tried either of these recommendations yet, but here is a response I'll share from an online site I paid to register with:
"Either you aren't getting enough
water pressure to the top spray arm, or some of the holes are still
clogged on the wash arm.
The holes you need to be concerned with
on the wash arm are the end holes and the holes on the BOTTOM of the
wash arm. These are the ones that propel and spin the wash arms around.
There is one hole on each end of the wash arm, and 2 holes on the
bottom of the wash arm (one on each side).
If you are sure that
every hole is clear, then it's just not getting enough pressure. On this
machine, that's likely because of the wash impeller developing too much
friction. This is not a "Do It Yourself Project". It involves taking the
dishwasher out and turning it upside down to remove the motor."
Do you have hard water in your area? I took apart the filters, and both arms -- they were full of hard water calcified "bits". These things spin by water pushing through them. Are the little holes on the end clogged?
Also, I found certain dished would poke through the rack and block the arms as well.

The arms do accumulate gunk that clogs the sprayers. Disassembly, cleaning and reassembly are not difficult.
However, I think that your problem may be in the main filter and strainer, which are located around the base of the bottom arm. Download the diagram of the model and remove, clean and reassemble. My bet is that you'll find a layer of sediment in the filter that can be removed with a soft brush and running water.
If you have pets that shed, be ready to find fur in the filter.
There are a few things that can cause this. If there are no error messages being displayed during the cycle, the most common ones are: 1) Loose Impeller on the motor rotor. Check it by removing the drain filter, dish rack, spray arm and main wash filter (the giant stainless steel circular one), then twist the motor to the left and it should just pop out. If you hold the bottom of the motor in one and and the larger impeller on top freely spins, this is your problem. 2) Crack in the side of the spray arm. If the spray arm is separated, then the water pressure will being spraying sideways, rather than up to your dishes. 3) Too much fat or protein built up inside. This happens when you put too much eggs and milky stuff in there. Just run it for a cycle with detergent but no dishes. DO NOT use one of those dishwasher cleaner things in a dish drawer, they do more harm than good due to the fact that they are designed for a dishwasher with double the capacity of yours.

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.
If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes. Hope this helps...
Clean the filter at the bottom of the tub. If it is dirty or clogged the water pressure may not be strong enough to spin the top arm. Make sure also the there is nothing blocking the holes of the spinner arm. If the filter and arm are clear then the pump may be failing.
After observing the water just gushing out when the spray arm was removed, we determined there was still a bunch more calcification/soap in the ends of the spray arm. (We have very hard water in our area). Unfortunately, you cannot open up the spray arms to clean them out, so it took about 30 minutes of pounding and manipulating to get all the gunk out. Now my dishes are clean again. Hallelujeh! And the water cleaning the dishes is cleaner, as well.
I had the same problem and found two things which were causing it -The O-ring was missing off of the tube connection on the back of the dryer that inserts into the sprayer tube. I found a size 11 O-Ring at Home Depot and it worked -The openings on the underside of the spray arm are what propels the sprayer to spin. I found small pieces of plastic debris in the openings and cleaned them out.
I have the same problem. The dishwasher has been working fine since we bought it 5+ years ago but now the top arm is not spinning and the upper dishes are not getting clean.
