Off balance spin/poor wringing

it could be a balance problem. Most machines are programmed to abort fast spin if the drum is unbalanced. This can be caused by too much in there, or possible the contents have clumped together somehow. Try a spin cycle only with an empty machine and see if it reaches full spin

You may have One wet heavy item (one sweatshirt or one bath towel) that is not evenly dispersed within the wash tub, and this will prevent the machine from reaching and completing the spin cycle.

you may need to put some anti vibration shock pads under the legs or some two sided tape to put on the feet to help secure it to the floor it may be slipping on the new floor surface

Hi,
Here is a tip that will help you with that...

Washing Machine does not Pump or Spin

If your machine ius a FAV6800A LED console or FAV9800A LCD console then take a look at this post Clutch Fix if you want to DIY.

I will help you through the process. Your looking at $300 to $400 for a repair if you don't DIY. See if the DIY process is for you if so let me know I have a few additional questions......Rich

The DC code that comes up is just saying that the load is "off balance" to resolve this, open the washer and redistribute the last and restart.

The bang fron the tub that you hear is just from the load being off balance. Generally it's just the weight difference on the tub when the washer stops spinning. This is normal for an off balance load and is nothing to be overly concerned about.

If you are getting the DC code a lot, take a look at the types of loads you are washing. Are they small? Is it a mix of small and large items? Is it a few large items? This may be the answer to why you are having off balance issues. The Neptune is a very large washer, and can get off balance very easily with smaller loads. Try making loads larger or if you are washing for example sheets, try washing them in 3's. This will make it easier for the washer to balance the load.

Good luck! Please let me know if this was helpful!

Open the lid. take one hand and push the tub back toward a back corner. Take your other hand and fill in the gap on the opposite corner. There should be a black round rubber strap going from the outside top of the tub to the cabinet. Once you find it check all four corners. I feel sure that you will find more than one broken. These help to keep the load balanced. It is very important that you change these as soon as possible due to after these break these machines are bad about the tub banging into the sides and cracking the outer tub. To replace the tub will run ( in my area) around $240 - $300. These straps are not hard to replace and don't cost very much. I would rate replacing them a 2 on a hardness scale from 1 to 10. 10 being the hardest.
Please rate this solution if helpful.

Too much laundry in your machine. Try a smaller load and see if you have the same problem

This sounds more like a motor control problem. You need to open the control panel and find the service sheet. This sheet will tell you how to run diagnostics and other tests on the machine.

either balance load sensor or machine failing to drain in the allocated time, check pump/filter for blockage
