hi all, i just bought a used old LG washer dryer all in one. it seem to work great but when the drain pump starts it is super loud for a few seconds then gets a little quieter but still pretty loud. its a buzzing/humming/vibration. I swapped the pump for a new one and it is still making the noise. it happens during drain cycles and drying cycles. the drain hose appears to be free of debris. i also tried to stop any pump vibration by stuffing a piece of rolled up yoga mat underneath the pump.
first video is during wash cycle second is during dry cycle
I ended up testing all wires to pump and through noise filter. everything appeared to be working properly. took fan apart again and took some length off the stator blades. also filed a little off the inside of the pump assembly. I think the pump assembly is possibly warped but the piece is discontinued. might try to buy a different pump and assembly that will fit. i also put some packing foam around the pump. it better than it was but far from quiet. thanks for the help gentleman
Hi, Try running the diagnostic tests for the washer and check if any error codes are shown. If there are any, they may help to further isolate what the problem is. Here’s the service manual for the machine. Go to p.13 in the manual (14/44 .pdf numbering) to view the QC Test procedure. If replacement parts are required, search online for LG wm3431hs parts to find suppliers that suit you best.
