20 Most Recent Oster Coffee Burr Mill - 6389 Grinder Questions & Answers


Apparently, you unplug the unit, dump any beans out of the supply hopper, then rotate the burr intake module in the bottom of the supply hopper counterclockwise. You can then pull it out, and brush it out. You also brush out the other half of the burr unit; don't put water or anything in it, you'll kill your grinder. You can, in theory, wash the removable module, but if you do, be sure it's ABSOLUTELY dry before you put it back together.

First I'm not a OSTER tech. But I have worked on similar table top semi-automatic machines. You should call your vendor for service as there is no customer serviceable parts in this machine. (Yes, I know you tried)
*** the following is for information only. ***
* If your leaking at or under the water tank then check for crack or you may be missing a rubber seal, o-ring, or washer. Replace the whole tank as a unit.
* If your leaking at the bottom, drip tray, or side only when the pump buzzes (pumping water) then there is a cracked or disconnected hose line or fitting. Check the hoses to the pump.
* If your leaking when the steam wand is in use then there is a similar problem with the 2nd pump system.
* The pressure is usually preset in the vibration pump. Some pumps have an adjustable spring regulator but since you have not touched this then either the spring is broken or stuck. You will have to disassemble the pump which is very tedious. I will leave several links below. Take your time and lay out the parts on a clean (colored) towel. Avoid using a white towel as some parts are also white.
* Final; Leaking water and electrical equipment is not a good idea. Best to be safe. Unplug, wipe down, and look for leaks.

PS Okay sorry I thought there was a posted video of the actual dis-assembly of the vibration pump. Looks like I will have to post my own tear down of this type of pump. I have several old ones. They are common on Amazon.com

Take it back to the store where you purchased it and get a new replacement. Some stores allow up to 90 days to return merchandise.

Check the hot plate at the bottom of the coffee maker, it should be hot and there is usually a setting to have it remain hot for 1-3 hrs.
