Bosch SGS4012GB/14 dishwasher - top arm not rotating/cleaning

I have a Bosch SGS4012GB/14 dishwasher which doesn't seem to be washing properly.
I have checked the filter, checked the outlet pipe drains stuff away, cleaned out the rotating arms... I have opened the door during the cycle a few times to see if the arms are spinning and spraying and they seem not to spin, but do spray water. It seems the water pressure isn't strong enough to spin the arms.
The top arm tilts a bit too...Can anyone advise what I can check next or if I can replace something?

    My solution that fixed it (since no-one commented...) was simply to risk buying a new upper spray arm.

    Worked a treat! Never washed so well in its life.

SOURCE: Dishwasher spray arms don't spin & spray water

Could be a a couple different issues.. Not filling with enough water or food chopper broke or food chopper filter screen clogged.

Check water level:
Run the DW and wait for the main wash to start (water will fill. pause then complete fill) The water should be no more than 1/4 inch below the heating element. If not there..replace water inlet valve.

Inspect food chopper:
1. Remove lower spray arm and rear water supply tube to upper spray arm.
2. Remove torx screws that secure the sump cover.
3. Remove primary filter
4. Remove food chopper cover to expose the chopper assembly. Inspect for breakage or blockage.

SOURCE: small plastic top and mid spray arm do not turn, bottom does

decrete, you want to get down to the chopper and screen. If the screen is plugged up with gunk there won't be enough pressure to reach the top spray arms. Check out the posted pics. Remove the lower spray arm. Rotate the rear feed arm to the right until it unsnaps from the tube going up the back. See the 4 torq screws holding the filter on. Remove them. Lift the filter up. Now you will see the chopper inlet cover. 1 torq screw holding it in. Lift it up and there's the chopper and screen. Catriver..post back

try http://www.bshappliancecare.com/Bosch/boschspares.html

it's pretty flaky and I didn't work when I tried to download a manual for my SRS43A02GB/08, but the parts-lists do.

If you go to the 'Launch the spare parts eShop' and enter your model number (you only quote it partially above, so you then need to select the particular model), you can see the exploded parts diagram - click right-hand icon 'print all pages' to get a pdf of all the exploded diagrams. You can order from here too and they seem a lot cheaper than alternatives, but I haven't actually bought anything yet.

SOURCE: Lower spray arm does not spin on my bosch dishwasher

Sounds like you may have put it together wrong. I would just take the arm back off and make sure that it all fits together right. A little tip for you too. Dishwashers will clog up all the time with water deposits and food gunk. There are all those expensive cleaners out on the market but the best and cheapest way to clean them is with white vinegar. Simply pour it into the dishwasher when it is empty and run it on the pots and pans setting on hot. Always make sure to pre heat your water too by running the sink till it starts steaming. This will make it easier for your dishwasher to heat the water. If you don't, then when you turn on the dishwasher it starts to fill with cold water and has to heat it on its own. Run the vinegar though through it at least once a month or so and it will extend the life of the dishwasher. Hope this helps. Just try taking that arm back off though and putting it back together making sure everything is fitting properly. If you have any other questions feel free to ask me. Good luck.

SOURCE: upper spray arm falls off during operation, even after snapping

the clips that hold it in place are worn. you will have to replace it. they are not very expensive. to remove it simply unscrew the round disc above the arm

Bosch SHU 8805 upper arm is getting no water.


replace the upper water arm conduit and wash arm hub as they leak under years of pressure and the o-rings leak water and then it can't hold pressure and supply the upper arm with full pressure water,also replace the center arm conduit if it has one as this will wear out too

Sprayer arms not spinning


I know this sounds too simple, but on My dishwasher which is an SHX46b model, the plastic supply arm that comes out of the pump and supplies the upper arm popped out of it's correct position at the base. It is held in place by two dinky nibs. I just popped it back in and voila, pressure was back and arms were spinning.

Clogged dishwasher arms


Our Bosch has a round knob in the center of the arm, under the basket. ROtate it 90 degrees, and the arm drops away and can be cleaned.

My Bosch dishwasher model #SHU43C05UC/14 drains well and has enough water(I replaced the inlet water valve already),but not washing the dishes clean especially the top rack.What could be wrong?


open machine when running and check both spray arms rotating - you will get a bit of water out. if spray arms not rotating, usual cause is debris in the arms. the spray arms only rotate by water jetting from angled jets at the end of the arms. take them out and make sure all debris removed
