Sounds like you have a hard water build up. You need to clean out your water hose. I suggest that you soak the ends of your hose in CLR or use a tool (hanger) to clean the hose out directly. Where the water comes into your washer may be blocked too so I'd giver a clean too!
To avoid this from happening again: Add more salt to your water to soften your water!
