I have a Samsung washing machine - WW80M645OPX
I require a drain hose extension. I bought the Washing Machine Drain Hose 2.5m x 21mm which i got from screwfix - https://www.screwfix.com/p/washing-machine-drain-hose-2-5m-x-21mm/71062?tc=CB6&ds_kid=92700055281954...
I was told it is incorrect size as the hole is too big to connect to the washing machine
i have looked at this:
Not sure if it is a correct size.
Can someone guide me what extension i require to buy?
