Hoover wdm120 washing machine not draining
 

Have found a hole in the long hose that runs from the top left of the
machine to the filter at the bottom left of the machine. The hole is
where the hose has been rubbing against the concrete part of the
machine. This has been leaking some water and the machine has not been
draining properly when it spins. The filter is OK itself.

1) Is the hole in the tube likely to be the only cause of the problem?

2)What's the name of this hose - several hoses available on the parts
websites but I'm not which one of the many available is this particular
one...
