I had the same problem Karen with my machine. Do you regularly open the small panel at the bottom right hand side and pull the little hose out & empty the water? once you have done this, also unscrew the filter cap & clean the filter out. I notice a big difference after doing this. hope this helps.

bosch exxcel 1400 not doing final spin as well as it used to although putting on spin cycle again helps.

If it is not trickling out from the door seal, next most likely cause is the supply feed pipe at the rear, and the linkage with the inlet. Pull the washing machine out, and start a cycle, and trace the source back to here...
