Drain the water out manually.
Once empty, take the filter out and use a long screwdriver to turn the impellor on the pump.
If it spins freely the impellor is broken off the pump.
If it pings round, set the machine to a spin and listen at the filter housing to see if you can hear the pump running.
If you do, you'll need to take the pump out and check for debris in the hoses and the pump ports.
Hope this helps
Let me know what you find.
From what you've just posted it would appear that you've dislodged whatever was causing the blockage.
You've run it once, now run it through a full cycle and see what happens.
It should work fine now.
You have to clean out the filter regularly.
Buttons, coins and bits of fluff can get stuck in it and can stop it pumping out properly.
Now that you've taken out whatever was in there it should be fine again, until something else gets stuck in it.
You'll need to strip the pump out of the machine.
I think you've either got a non return flap (rubber) on the pump or there is something stuck in there that moves and acts as a butterfly valve.
If it's a non return flap, I'd suggest just removing it and ensure the drain hose is high enough to prevent back syphoning.
If it's a blockage, just clean it out and reassemble the appliance.
It's ok, I do know it's a front loader with direct drive motor.
At worst you may have to replace the pump but I think you'll find that taking it out and checking it will reveal the problem.
Let me know how it goes or if you need further assistance.
I'll see if I've got anything to help you when I get into the office tomorrow.
A non return flap doesn't keep the water in the machine, it stops dirty water being sucked back in, hence the reason I said to keep the drain hose higher than the machine.
Unplug the appliance, pull it out and take the rear cover off.
Open the filter door and take the filter out.
Take the plastic panel below the front panel off.
Undo the screws holding the filter housing.
From the rear, take the pump and filter housing out, disconnect the wiring and the hoses from the pump.
Check the hoses for any debris.
Now the pump is out, check it for this item that keeps blocking it, remove it and refit the hoses and wiring to the pump.
Refit the pump and filter housing, refit the panel and the filter.
Try the machine out.
If I find any diagrams, they will be exploded parts views, they don't always help but I'll post them tomorrow once I get in the office if I have them.
