Why doesn't my Bosch SHU43 c06uc dishwasher have any cleaning force?

With your dishwasher empty, roll out the bottom rack. The feed line for the upper spray arm runs from a pump outlet directly behind the lower spray arm spindle. This tube runs up the back wall of the dishwasher and mates with the upper rack when it is pushed in.

This feed tube simply snaps into place in the bottom of the machine. It is a high pressure line that makes an immediade 90-degree bend towards the rear of the unit. They have a tendency to pop out. When and if it does pop out you get almost no water coming out of the upper arm and you lose effective pressure in the lower arm, too. The cure is to push that feed tube back down firmly into the port until you hear it snap into place. While you have the lowere rack out it is a good idea to clean the intake screen out and check for any debris in the intake well.

It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher.
The motor (and pump) located beneath the dishwasher.
Check if motor spins. In case it spins, the problem is with the pump ,in case it doesn't spin it could be a motor problem or a motor and pump problem.

First of all: filter plate clean? Clean any locked hole.
1) Can you remove the upper spray-arm and verify if holes inside are locked by any residus. Clean the holes , and check if pure water come out when you fill the center hole with some water.
2) Switch on the dishwasher , coldest wash cycle dish-washer empty and without the upper spraying arm. Once you hear water streaming in, open the door and look if a little water fountain comes out from the center hole where the upper spraying arm was fixed. If not, this canalisation is blocked and should be cleaned. Try to continue the wash cycle, often the water pressure will clean itself this canal. Check also lower spray arm: it should be rotating a while and ejecting water thru its holes. If not, verify this canalisation as well.

3) Put the spraying arm again on its place, verify also the sealing else water pressure is going down and spraying will not turn and spray water.

4) Again, continu a wash cycle, open the door and look; upper arm should be rotating and some rays trown out.

Hopefully, this helps .

If not, pump pressure may be low; have a repair verify, can be that only brushes in the motor must be replaced, can be the pump worn out and to be replaced at all.

Frigidaire Dishwasher Professional Series runs loud now and the dishes aren't clean when it finishes its cycle.

Check the water supply line for kinks, check bottom strainer/drain inside to remove particles/trash blocking water from exiting to pump washer motor, be sure no items block rotation of washer heads. Good luck.

After filling and only when rinse commences a loud chattering noise begins. Somewhat like a circuit breaker making intermittent contact. It ends when I cancel and remains silent while the pump empties...

  • It sounds like you have an obstruction with upper or lower spray arm. check to see if the something is stuck in the path of the lower spray arm.
  • move the lower rack out
  • spin the spray arm by hand to see if it is hitting anything
  • if not .....spin the upper spray arm by hand under top shelf to see if it is hitting anything.
  • let me know how this works

Upper Spray arms not spraying

Took apart again and found the stepping motor which diverts the water from lower to upper spray arms to be burnt out. I was able to manually set the diverter to the correct position so the dishwasher works but I am waiting for new parts to properly repair the problem.

LG LDS5811WW Low pressure out of spray arms

On the LG LDF xxxx dishwasher family, the Vario feature uses a motor/check valve to switch between "full power" cleaning from _either_ the lower or the upper spray arms, never at the same time. So, not seeing the upper arm spin during the lower arm spinning is standard operating procedure.

But back to your problem. Step one would be to remove the filter assembly again and make certain that there is nothing (debris, broken glass) blocking the white areas where the check valve rotates to switch between upper/lower spray arms. A blockage there ~could~ cause impotent spraying/cleaning.

If there is no blockage and the impeller remains in good shape, suspect a failing wash pump motor. Try to isolate the noise to that motor.

Watch for error codes on the display and report back what you find, OK?

Good Luck!

LG dishwasher does not seem to clean items on lower rack

Can you tell me if the problem was fixed by the original posters?
The multi-level wash direction feature uses a check valve just below the mesh filter asembaly and is driven by a vario motor underneath the check valve. By removing the mesh filter (10 screws and the lower spray arm) you expose the check valve. It is very close to the pump that empties the water through the drain hose.

High probability problems: -The Check Valve could be jamed/stuck. -Also, the Vario Motor could have failed
Please respond back with the findings on this problem. Thanks!

Dishes not getting clean

Yes I had the same problem and just fixed it for $7.00. Did not even had to take anything apart. This is what you will have to do. If this dosen't work then try what these experts are suggesting. Please follow these steps for optimal results. #1 Break off a plastic Tea spoon. #2 Put it in place of a LATCH to by pass so you can watch the operation of the dishwasher.(put down some towels for water spill) #3 start the dishwasher on normal cycle. #4 Pour in Gallon of White Vinegar($2.00) while the Dishwasher is being filled. #5 Let it run through its cycle. After the cycle is complete water will drain out and then actual cleaning cycle will start. Then #6 while the dishwasher is being filled again pour in 48 OZ or bigger bottle of CLR (Calciam Lime Rust) it is available at Meijer, walmart, Rite Aid, Home Depot Ace Menard's etc. for $5.00. sit by the dishwasher and listen for it. if you hear water draining pull and push the water plunger so it won't drain so you don't loose your CLR down the drain. since you have the spoon in the LATCH your dishwasher will always be on so BE CAREFUL when you stick your hand in it. And after the cycle is complete enjoy your NEW DISHWASHER.
