Amana Frontload Washer Stuck in Drain Cycle

I have an Amana Frontload washer model number NFW7200TW, it seems to be stuck at the spin/drain cycle. There is no more water left in the drum and the pump cycles off and on but never gets past that. I removed all the drain hoses and verified there is no obstruction and I even removed the drain pump and disassembled it for a good cleaning and to check for debrie. After reassembling and installing the pump, it still does the same thing. I took the exit hose off and let it run and it seems like the drain pump is working because I can feel air coming out of the exit valve as the pump runs, however, it doesn’t seem like there is as much pressure coming out as I would imagine needed to move waste up the hose. In fact it doesn’t even budge the small black rubber flapper that covers the exit valve on the pump itself. Is this normal? I’m thinking I may need a new pump, but that still doesn’t answer why when there is no water left it won’t move past this point in the cycle. Also, my drum never spins…probably because it needs some signal from the drain pump I imagine. I am mechanically inclined and don’t mind doing the work, just need some direction. Help please!!!

Here is the tech sheet perhaps it will help you narrow it down.

The pressure out from the pump is probably OK as it is meant to pump water not air so will not have much pressure with air. Also you have to be careful to not run it too long when it is dry as you can overheat/melt the pump vanes.

Thanks for the tech manual…I’ll have to put off the troubleshooting/repair for a while. My wife decided to seize the moment and upgrade to a top of the line Samsung instead of fix the washer she hated anyway. For now it’ll sit in garage and when I get around to working on it (never) I’ll use the manual. Thanks for your response, take care.

MY machine is doing the same thing its amana brand
