Trying to find out the primary reason for the error codes appearing on your Samsung front load clothes washer can be quite daunting and worrisome. It is all a matter of trial and error to figure out the actual cause of the error codes. Although Samsung does post up various error codes for their clothes washer in their website, and possible solutions to fix the error codes, I have found in my personal experience they may not always be true. It could be something closely related to the actual problems and solutions.
Some of the things you could do about your Samsung front load washer are as follow:
1. If you are getting the "SUD" error code, according to Samsung's website, it means that either you must be using a lot of laundry detergents or you are using the ones which is not HE compliant. In other words, you could be using some cheap laundry detergent which is causing a lot of SUD (Bubbles) in your washing machine.
The Clothes Washer detects too much of SUD and tries to reduce the amount of SUD by sending in more water and draining out the water. This may take 2 more hours added to your normal wash cycle time. So you may experience longer than usual washing time.
From my personal experience, I used to love putting lots of laundry detergent, well over the "MAX" line in the Samsung washer detergent compartment. But when this error code started to appear, I checked out the Samsung website and reduced the amount of laundry detergent below the "MAX" line. Even though I did that, I still continued getting the same error code "SUD". That is why I say, not all solutions mentioned by Samsung website will work for all error codes. There could be more underlying problem closely related to the actual problem.
2. The "SC" error code appearing on your Samsung front load clothes washer, could mean that your washing machine is not draining properly. Some of the places to check are the actual drain hose connecting to your house drain. Something could have gotten stuck in your drain hose.
Your drain motor pump could be malfunctioning which is why the water is not getting drained properly.
Now, this one below is the most probably cause. There are dirt and stuff stuck in your Washer's drain filter. In my case, there was a Loonie coin stuck inside this drain filter. By removing all the debris and dirt from this drain filter compartment, your washing machine will begin to run normally. For me, when I removed these coin and stuff stuck inside my washer's drain filter, even the "SUD" and "SC" error codes disappeared. I tested and retested after that and no more error codes again.
The drain filter are usually located in front and near the bottom of the clothes washer. You just need to pop open the lid with a screwdriver or something thin, and you will see a black rubber pipe with a plastic knob on the side.
In order to drain the water out manually yourself, you can simply unscrew the white tip of the black pipe, and collect the flowing water into a shallow bucket. Once all the water is completely out, you will then turn the white big knob anti clockwise, which is located beside the black pipe. Here you will find all sort of dirt and debris coming out from your clothes stuck here. Take the drain filter out and wash it every 3 months or so. Look for any big hard debris stuck inside that may be causing the blockage. Once you are done with your cleaning. You can screw back the drain filter and replug the black pipe with the plastic tip.
