U1 Fault on Dishwasher and wash pump will not start up?

Thanks Lincoln just found a Rubber ring loose in the wash pump veins.When i looked down from inside the mc i could see it when i spinned them round.I take it this was stopping the pump from turning.I pulled the ring out now and not sure where it's from??
The machine is now cycling but there is a small drip now from the edge of the plastic round tray dripping to beneath,from above wash motor.It may just be because the silver mach plate has been removed about 10 times yesterday??
Any ideas on the rubber ring ??and if it's ok to run without it??

U1 fault means it failed to prime with water within 3 minutes. First check that water is coming in. Can you hear it coming in and see it when it starts to wash? If not check tap is fully open, check water inlet hose for obstruction, maybe inlet valve is faulty. If water is ok then check that spray arm is in place. Check rotor assembly beneath spray arm. Is it locked into place properly & plastic piece on the top (like a fan) is not loose on shaft. If in doubt and water level is ok, fit a new rotor assembly.
