Thank you for reaching out to us!
Have you tried the following:
To keep your washer tub clean, use the SELF CLEAN cycle at least once a month or every 20 cycles. Perform the recommended procedures below when using the SELF CLEAN cycle.
On 2011–2013 models, the SELF CLEAN cycle is labeled “Pure Cycle.” Remove all items from the washer tub and ensure the tub is empty. Laundry left in the tub during the SELF CLEAN cycle may be damaged.
Press Power to turn on the washer. Turn the Cycle Selector to SELF CLEAN (or select Pure Cycle). Press and hold Start/Pause (Hold to Start).
After the SELF CLEAN cycle, leave the lid open to dry. The water temperature for SELF CLEAN is set to Hot and cannot be changed.
When noticeable residue is present in the washer tub, add 1 cup (8 fl.oz or 240ml) of liquid chlorine bleach to the bleach compartment before you start the SELF CLEAN cycle. Do not use or mix any other detergent or chemicals during the SELF CLEAN cycle.
If necessary, run a RINSE+SPIN cycle after the SELF CLEAN cycle has completed to help remove any residual residue. Please be aware that certain usage and environmental conditions may result in residue build-up or odor in the washer tub.
Caution: Check the washer tub before using the SELF CLEAN cycle. Remove any water remaining in the tub by running the SPIN ONLY cycle before starting the SELF CLEAN cycle.
If there is chlorine bleach left in the washer tub for an extended period of time, rust can occur. If you have additional questions you can go here: https://www.samsung.com/us/support/troubleshooting/TSG01108629/
Is anyone aware of a lawsuit against Samsung for this mold build up issue?
The faulty design of the machine is to blame here. For all of us who do consistent self cleans, leave the lid open, don't leave clothes in washer etc. are left with no solution except replace the machine. They call it a "maintenance" issue. The reality is, the machine leaves inches of water in the bottom after the cycle completes. I know this because I took the machine apart and investigate and try to save it. The last moving part in the very bottom, underneath the drum was covered in sludge and mold. That build up is not going to be solved by self clean cycle. Water always sits there. The metal parts were oxidized together. There's no saving the machine. It's not operator error as they would like to classify it and the bigger problem is the health hazard!! Users have been exposed to mold and mildew build up without even realizing it. Samsung what are doing to fix this? Offering refunds to replace the machine? Extending your warranties to cover the damage??
I've had my Samsung washing machine for a couple of years since my original one purchased in 2015 was replaced due to a recall. I noticed dirt, sand, moldy gunk collecting on the bottom of the machine. I of course ran self-clean cycles many times with bleach. I continued to clean the bottom out after each wash with paper towel. I also took the agitator plate out of the bottom, along with the drum itself and found the most disgusting pile of moldy dirt on the bottom. It's absolutely disgusting. I cleaned everything the best that I could with bleach, paper towels, hose, and a toothbrush of all things to get under the main spinning part that refused to come out. I am currently running a second self-clean after this work. There is still dirt collecting at the bottom after all the cleaning I did. What is Samsung doing to address this common issue with their top loaders?
I have a ~2 year old WA52J8700AP. Great washer except it leaves mold build up at the bottom of the washer. I learned this after flakes starting building up after washing. I took it apart to find the outside of the drum and bottom of pulsator filthy and coated with dirt and mold. Smelled atrocious. Very common problem it seems.
it is now spotless except the pulsating itself. The pulsatornis metal with plastic clamped on underneath. I can see mold in between the two and I believe this is what is causing continued flakes and dirt. Everything else is spotless. Is their a warranty or recall in this part? Is there a way to open it without brute force?
I'm sorry to hear that just to confirm have you done the following?
If none of this helps you can send me a private message with your full model and serial number and pictures of your symptoms so that I may look into this?
I literally disassembled the washer, scrubbed the drum, pulsator, and tub with bleach and brushes. Do you think I would have done that without running the self clean cycle first? The self clean cycle does not solve the common problem of built up mold and dirt at the bottom of these machines. We also already leave the lid open when not it use.
My question wasn't about how to run the self clean cycle. It was about cleaning the pulsator itself? Is there a way to open this? You can see the mold built up underneath the transparent white plastic between it and the metal.
Did you take the 6 arm bracket off the bottom and clean it? It's carbon steel which is pitted and holds moisture/scum. The bottom side of it is baffled with tons of crevices for gunk to build-up.
This is the best reply I've gotten so far. I did not but I did modify a brush to scrub the pitted areas you mentioned. I noticed them and was aware they could be a problem area. I got them clean. I spent a few hours hand cleaning it. The steel 6 arm part looked like it was pressed on. Is there a way to remove it?
I think the remaining flakes are coming from in between the metal and plastic on the pulsator/agitator plate itself. There are something like 6 holes in each of the 6 section in the plastic under lining of the agitator. I removed any build up in those, lifted as much I could with a screwdriver to get as much as possible beyond the holes. I can't separate the metal and plastic without destroying the part... that's really what my question is about.
The 6 arm bracket is held on by the big nut on top of it but it is reverse threads so lefty tighty righty loosey. I had to put channel locks on it and hit them with a hammer to break it free.
I didnt have any debris inside my pulsator plate (had a ton under it) but I'm pretty sure you'd destroy it if you tried to separate the metal from the plastic. I hope you get everything resolved if you are as frustrated as I was.
