Alan D. for Model Number LDS4821ST My LG dishwasher LDS4821ST, just started making a loud screech ing sound during the wash and rinse cycles. I have used it maybe 5 or 6 times since this started and the noise is more consistent and loud. I removed the lower wash arm and lifted the cover screen at the bottom of the unit but found no obvious problem. It has continued to clean, rinse, drain and dry the dishes but I'm concerned about the noise. Also, their have been no error codes on the control screen. What do you think?
Answer Alan, If there is nothing caught down in the pump assembly then this issue would most likely be caused by a faulty motor bearing which you would want to replace the motor for this issue. Read More... Answered by AppliancePartsPros.com | Monday, March 20, 2017
