Hotpoint aquarius washing machine water not draining away only few months old

Hi, Ok first things first where is your machines waste pipe connected? If it connected to the sink trap check there first by undoing it and check that there is nothing inside stopping it from letting the water out..?
If this is clear then have you lost anything? Sock? ETC....? Can you hear the pump? And is the water draining but not spinning?
If you cannot hear the pump running then it will more that likely be the pump as they are a magnetic pump which fail quite alot. If the pump is running then it is going to be something you have lost which will be located in the sump hose underneath the machine whic comes from the tub to the pump. Take it off and check and clean as nesscerary. Or last but not least it could be the fact it is doing everything but not spinning ( no drum action )? Check the motor carbon brushes if they are low then this will cause the problem or the motor has failed!....
Good luck and let me know ho you get on??
