Replace carbon brushes

I think this juicer is made in france, depending where you live parts may be hard to get , If ok when stored it may have stuck brushes or a corroded switch , ask for a written quote if you take it for repairs as it may cost more than a replacement.

You can brush it with a new tooth brush, or soak it in vinegar for a couple of hours.
After getting rid of the old residue, you need to rinse it off right after juicing the next times.
Best types of juicers

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.

The reset button is actually a circuit breaker in miniature but there may be a thermal fuse to protect against fire in case of failure of the circuit breaker.
If you are game, open the housing again and look for a device you don't recognize that is in series (in line) with a wire; it may be in an insulating sleeve and not immediately visible, appearing only as a thickening of the wire. This could be a thermal fuse.
They are not supposed to open under load but only when the temperature exceeds a limit and these do not reset. Unfortunately, these are now all coming from China and are not very reliable so may open even when the design temperature is not exceeded.
If concealed, you would need a simple multimeter to determine if it had 'opened' by checking for the continuity of the wire stretch.
Blenders in general are 'universal' motors which can use AC or DC and this type employs carbon brushes which do abrade with time and when they have become too short, they can become intermittent and cause such a popping sound too. Brushes are replaceable so you might check Waring's website to see if they offer a fixed-price replacement or brushes as replacement parts.
I would be prone to see the Waring restored since most replacement blenders are from China and have often more than just one problem even when new. One given to us as a present smoked while crushing ice so we retrieved our old Oster from its stash and tossed the oriental wonder.

I usually use towel or thick disposable dish pads

The basket may have cut into the hex shape top of the spindle creating little grooves which
the basket locks into. If that's the case you have to replace the part, it's called the impeller.
If you can purchase one from Omega, use a needle nose pliers to remove the flat hold down
washer/nut on top of the motor spindle, pull off the old impeller and push on the new. Line
it up correctly it only installs in one position. The impeller is the flat rotating part that the
basket sits on. I did it on my Acme but had to push a little for them to sell me one.

I had the same problem but discovered that it is just tightly stuck together. Pull straight up on the strainer, it is difficult but it will pop up. The base piece will follow.

I've been using my Champion for about 20 years, and have always used a very thin coat of olive oil on the turn shaft before sliding the cutter on. I've also used it before I've used the grain mill, and it has been fine.
If I were you, I think I would get out as much Crisco as I could with a chopstick (or something similar), put in some liquid soap, and some hot water. I would think that would loosen anything that was compressed or stuck. It might take a few times, but that's what I would try....or you could order a new cutter from Champion. I've had to order parts from them in the past, and they have been great.
Hope this helps.....
