Product review (5 stars): Exact Replacement for DC61-01558A (actually was a DC61-01558A) and Instruction on how to install/replace in Samsung Washer.
I own a Samsung WF339AAW/XAA Clothes Washer with SilverCare.  I knew that the silver anodes needed to be replaced at some point but never really found any information on how to know and where to go to have the feature replenished. Here's what I have discovered.

1) The common Samsung part number for the Silver Care unit which needs to be replaced is DC97-10417A, however the part number off the actual part in my the washer is DC61-01558A. A search for this part number claims it has been discontinued.

2) You can get a status of how many cycles the SilverCare unit has gone through by turning on the washer, then pressing and holding both the Signal and SilverCare buttons. The display should show something like UL1 or LU0 when the display shows LU0 Samsung wants you to replace the SilverCare unit. I believe this indicates the unit has been run 1000 cycles.  You will need to reset this counter once you replace the unit I'll proved instruction for that below.

3) To find the part,it's very easy, but does require opening the washer. You remove 2 philips/hex head screws located on the rear of the machine in the top right and left hand corners to remove the top panel of the machine. It slides towards the rear and just lifts off. This is very easy. You will find a metal rail/bar running from the front to the rear of the machine above the tub right centered in the the middle. My unit had some foam rubber to reduce noise which obscured 2 Philips screws that hold the SilverCare on to the rail. You will see/feel the SilverCare unit approximately midway on the underside of the rail. It has 3 water tubes and 2 wires connected to it. The rail also has a grove that fits into a tab on the SilverCare unit that prevents it from falling off the rail once you remove the 2 screws. You push the SilverCare unit towards the rear and to the right of the washer (standing in front) to remove it from the tab, no force should be required to release the unit, if you are forcing it or pulling hard something is wrong it only needs less than 1/2" to release from the small tab.

3) Once the unit is lose, I would recommend getting a Sharpie and marking the color of the wires and where your tubes connect (mine had the Yellow wire connecting to the rear terminal Brown wire connecting to the front terminal. The tube from the rear of the washer connected to the top connection marked IN and the tube running to the detergent dispenser connects to the lower connection on the rear marked OUT B. The small tube running to the tub connects to the only small connection on the front and the larger front connection remains open (Marked OUT A).

NOTE, the electrical connections use spade connectors and just pull off the terminals. The tubes are secured by friction and tube clamps you can release by pinching them with pliers. Removing the tubs from the SilverCare unit was the most difficult part of the job and it was still moderately easy and did not require any specialized tools besides channel lock pliers, but I can imagine you might be able to do this without any tools if you had too but it would be hard on your fingers.

4) To install the replacement unit, just reverse the process...

5) Reset your SilverCare counter. With the unit OFF, hold the Signal and Delay Start buttons and while holding them, push and hold the Power button for about 5 to 10 seconds, you should see the word GOOD on the display and it will eventually go away and the unit will power off, then you are done. You can check your counter again once you turn back on the washer and hold the Signal and SilverCare buttons, you should see LU1 again.

It took me about 5 to 10 minutes from start to finish to replace the part and I didn't even need to move the washer. The only reason you would need to move the washer is if you need more clearance between it and the wall to get a driver or ratchet in to remove the 2 rear screws that hold the top on the washer on. I would recommend a ratchet over a screwdriver (Metric Size 10).

Other notes:
The replacement part I ordered from Amazon Prime here: https://www.amazon.com/dp/B01AQI1ID8 was the exact same part that came out of the washer... molded with the number DC61-01558A on the part, it DID NOT have part number DC97-10417A on it as described on Amazon... which was great because DC61-01558A was what I needed!

I don't know if the silver panels in the unit are coated with silver or are solid silver, but I can still see them in the depleted unit, they look slightly corroded but about the same as the new unit, so I'm questioning if the unit really needed to be replaced after 1000 cycles? I might open the old unit up and inspect it a little closer but anticipate it will be hard to reseal so it doesn't leak.
