Tony for Model Number LDS4821ST I have lg dishwasher.Turns on starts the program and after 2-3 min stops and stays on the same time (is not going forward with the cycle.) I can hear small buzzing noise from the bottom. Buzz 3-4 times and stops and repeats the buzzing again. Can you tell me what is wrong and which part i need to buy? Thanks tony
Answer Hello Tony. If the unit is filling with water and then just hums, you will need to check and see if something is stuck inside the sump and is jamming the motor. If not, replace the motor pump assembly AJH31248608. If it does not fill with water, you may need to replace the valve 5221DD1001F. Hope this helps. Read More...
