The LG 2040 dishwasher started with a motor noise that got louder. I eventualy replaced the motor & pump (found windings burnt) but the noise continues. The capacitor is 4.5U Farad instead of the 5 UF it should be. The internal arms turn freely etc. What can cause this noise while waqshing?

It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.

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.

Take the main wash arm off and the sump cover below it. Remove the part you'll find under that to gain access to the cutter blade attached to the end of the motor shaft. Remove blade but note that this is a LEFT HAND SCREW. Now lay dishwasher on it's side and remove screws and electrical plug to motor. Reverse procedure to install new motor. It's not really very difficult.

Hi
soyunds like it flooded the base
You need to dry out the base of the machine thoroughly and it should re set

Well done by resolving this problem. The other way to avoid the siphoning problem through the drain hose is adding an air gap valve/connector (available at any hardware store). You can use it even if you don't have a garbage disposal in your kitchen sink. That will assure that you have the proper height of the drain hose.
Hope this helps!
The main water pump on this model does not last long. The water seal between pump and motor starts to leak that result in the adjacent motor bearing corroding and eventually failing, resulting in excessive noise. Later the water leak becomes so bad that it triggers the "E I" water leakage display and prevents it from completing the program. The pump and motor is sold as one unit and the whole unit must be replaced. I have tried to replace the faulty bearing and repacked the rubber seal with silicon grease but with no success. If anyone have repaired the water seal successfully please let us know.
