I know how disappointing it is to find your washer isn't working properly. I was able to find a link that includes helpful information for a washer that won't drain properly. I attached the link below. I hope this helps.
I know that it can be very frustrating to have issues with your washer. However, without the model number, I can only provide some general information on the issue. You did not state how much water is left in the tub after the spin cycle. Are the clothes pressed up against the basket indicating it had spun or are the clothes still saturated with dripping water? You also did not state what spin speed you have it set for and how tall and how long is the drain hose. Have you tried a faster spin speed? The drain pump may not be able to pump water up high enough on the slow spin speeds. Is the drain hose routed up too high or pinched/crimped? The maximum height is 96 inches measured from the bottom of washer. Is it leaving water because it's not spinning or not spinning fast enough? Does it make the noise during spin or agitate or both? The noise could be something in the drain pump, clutch or the basket drive. If you need further assistance, please reply to this thread with your model number. Thank you for using Manage My Life.
