I need to remove the parts for washing How I do this?


Things You'll Need:
  • Soft-bristled brush
  • Stiff-bristled brush
  • Dishwasher (optional)
  • Mild detergent
  • Lint-free microfiber cloths
  1. Unplug your Acme 6001 Juicer. Carry it to a countertop near your kitchen sink.

  2. Remove the pusher and cover, and set the pieces in a sink. Unscrew the clutch, remove it and set it in the sink. Remove the cutter blade, strainer basket and juice bowl, and place the pieces in the sink.
  3. Discard or remove and store any pulp that you find in the strainer basket. When you're finished, rinse the remaining fruit and vegetable pulp and juice from the pieces under cool, running water. Dislodge hard-to-remove pulp from the cutter blade and strainer basket with a soft-bristled brush or with a stiff-bristled brush if necessary.
  4. Wash the pieces in a dishwasher or by hand. To wash in a dishwasher, place the stainless steel pieces in the lower rack and the plastic in the top rack and wash on a normal cycle with other kitchenware. To wash by hand, fill the sink with warm water and a few drops of mild detergent and wash with a lint-free microfiber cloth.
  5. Run the pieces through the rinse cycle in your dishwasher or rinse under running tap water by hand. Air or wipe dry the pieces.

  6. Wipe the base with a slightly soapy cloth. Rinse with a damp cloth and wipe dry. Reassemble your juicer by returning the pieces to the base in reverse order.

Left earphone keeps dying out and comes back. Also the red light on the mic keeps coming on which blocks me from talking online.

I fixed mine by removing the soft ear cup then the two screws under this cup then carefully pry that top piece off the next lower piece. It will come but it is stuck with some soft glue.
Next, unsolder the two wires on the back of the speaker taking note of the polarity. These wires are what are broken. Undo the screw in the center. With a small screwdriver carefully pry the pivoting cup off the ear piece. It is snapped onto a small ball joint under the screw.
Now remove the four screws and remove the top of the ear piece.
Remove the two screws from the small printed circuit board and unsolder the two speaker wires. You will need to find some new wire that is flexible and not much bigger in diameter. I used some that was too large and had trouble getting the last cap that holds the soft ear cup back on. I also reamed out the holes in the cap and the cup that the wires go through to give them more movement.
Replace everything and solder the wires to the speaker in the same order as removing.
You will need a good small tipped soldering iron.

Good luck

Can not hear out of ear piece, but speaker works fine. How do i get sound back on ear piece?


There are 3 solutions 1st you can take it to where you bought the phone and they can replace it if your warranty is still valid or if you have insurance on your phone. 2nd you can take the phone apart (open where the screen is) i suggest only doing this if you are sure you can put it back together and check the ear piece, if it has dirt on it try to remove it, but be gentle. Also if there is nothing visible that looks like it got disconnected its broken and you need a new ear piece. 3rd get one of those headsets and use it like that

I dropped the phone. the piece that cradles the mouth/ear piece broke off. Can this be fixed and can I buy a replacement? Thank you


Maybe. You can get some epoxey and perhaps mold the piece back on - I have had very limited success with this. Make sure to follow the manufacturers diretion - then add 24 hours to the sit time.

Let me know how this works for you.

Dropped in water


I got my i870 from my sister a week ago, i got it for boost mobile but the ear speaker doesnt work either, i took it apart and i ordered the flip part of the phone which comes with the whole top section. It should work after i put the new part. it was only $26 off of ebay. the parts were only held up five screws. really easy but you have to be careful and gentle.

Dropped my Sanyo Katana cell in a cup of soda!!


probably too late but he first thing to don in that sit. is rinse the phone in a 75/25 solution of alcohol and water. then open up as you did and let it dry. if you can see water on the display screen your probably out of luck but keep it warm and dry for a few days and see what happens.
