Hi, welcome to Just answer
Please tell me its complete model number
and how old is it ?
AN74155LW 3years old
ok, and where is that noise coming from ? Is it like a loud noise or just a faint one ?
Sounds like it's from the bottom front of machine quite loud
ok, have you installed the pump yourself or it was replaced by someone ?
Anyways, if you have not followed the reset procedure after the pump was installed then please reset the washer. To do this turn the power off the machine and then select 90 degree wash with the washer still plugged in. After this is done press and hold the START & CANCEL buttons at the same time for around 5 second and simultaneously turn the power button on whilst still holding buttons down - Start light will flash.Leave power on and then Select any Spin position. After this, Press START & CANCEL button at same time again for 5 seconds - other buttons may start to flash - if they do, press START & CANCEL button together again for 5 seconds.
Let me know how it goes
