Amana front load washer has wet clothes after the complete wash cycle finishes

From the information you have supplied, I suspect that the machine is not draining the water away,
1] Check that the drain pump is working (it would be easier to hear it running, before the machine starts the spin cycle, or if your machine has a "drain down" feature)
2] If the pump is running, stop the machine and unplug it from the mains power. Remove the machine drain tube from the point where it is plumbed into the household waste pipe, and lay it down into a bucket, or large pan and allow the water to drain down [ you should expect to get up to 2 gallons (10 Litres) of water from the machine]
Allow the water to drain down completely by holding the drain hose as low as possible into the bucket.
3] once the water has drained completely, remove the drain hose from the pump and check that the drain hose is not blocked.
4] If the hose was clear, and the pump was running (in tests [1] & [2] ), it will be necessary to check that the drain pump, and the main hose from the tub to the pump are clear of obstructions.
Remove any foreign objects, and re-assemble the hoses to the pump to the machine, and the drain hose to the domestic plumbing.

Plug the machine into the mains power, and and set the machine to run on the "last rinse" and "spin" cycles and test to see if the problem has been rectified.

I hope this helps cure your problem.
