Need new base for dicer. The part where the grid slides in

If the base is gone, you may as well buy a new one. It is old and discontinued. You can ask the maker.

read your owner manual section troubleshooting. However you must test the control board fro defective, but test the main switch for defective use the multimeter for continuity and replace it

slide it over the blade ,, so that it sits between the blade base and the pitcher bottom

The gasket goes between the plate to which the cutter is mounted and the base of the jar. i.e., atop the cutter and contacting the base of the jar.

There are two phillip head screws holding the blender end together where it came apart. They are hidden under plugs on either side of the imprinted information. Simply drill a hole in each plug and remove them by putting something in the hole (small screwdriver) and pulling them out. Loosen the screws, enough to pull the body apart far enough to insert the blender end back in. Make sure you line up the drive pieces and the logo goes on the side with the switch.Tighten the screws back up and your good to go. I left the plugs out, they don,t serve any purpose.

Grease can only creep into the blender vase if the oil seal has worn out, or the blenders blade shaft is worn and wobbling. Try cleaning all parts in alcohol to soften the seals. Rebuild kits and replacement blades can be found here (http://www.brevilleusa.com/breville-parts/blending.html)

yes you can get a new base. your best bet is to google the brand name and buy the part from the manufacturer

Place food processor attachment on base
Put work bowl on gear collar with left slot just to the left of the tab on left side, slide until tabs click
Place work bowl lid on top of workbowl with tabs slightly to left of work bowl handle - slide into place until it clicks

you will need to buy a new blender the motor for your blender is burning and it is difficult to get parts for it.goodluck.
