Thanks for that.
You will have to unplug the appliance and pull it out.
Then remove the top off, towards the right you will see pressure switch with thin hose attached to it.
Remove this hose and blow through it, ensure it is not clogged.
Then reconnect and try again, it should work fine.
However, if the issue is still there and it wont take the softener then try to clean all the hoses attached to detergent drawer.
To do this check this VIDEO, it will give you an idea on how its cleaned.
If you have any further questions, do not hesitate to ask!
