Tech Tip: Samsung FL Washers Not Spinning

[LowSL2]

SAMSUNG BRANDED FL WASHERS

MODELS: All Samsung FL Washers

ISSUE: The washer will not go into a High Speed Spin when in a cycle but it will in the diagnostic test mode.

EXPLANATION: If the washer will not go into a high speed spin when running a cycle, but it will in the diagnostic test mode. Be aware the control is not looking at the Pressure Switch feedback into the control before going into a spin. If this is the case; then you should first look for either an issue with an out-of-balance load, overloading, unleveled washer, or oversudsing. Even if you cannot visually see suds in the washer drum due to the low water usage, there can easily be enough suds located inside the outer tub, hoses and pump that can cause the pressure switch to sense oversudsing. Run the diagnostic frequency test on the pressure sensor to confirm the pressure sensor is not at fault.

NOTE 1: If the washer spins in the test mode the Control Board is good.

NOTE 2: Use the 2+2+2 rule; use no more than 2 Tablespoons of Detergent, Bleach, and Softener

Have you ever run into the situation where the Samsung washer will struggle to get into a high speed spin? Almost it feels like it is missing a gear. I was working on a Samsung washer this afternoon and the machine was shaking violently as it tried to start a high speed spin. I actually had to hold the tub to prevent it from banging against the cabinet. Once I stabilized it it went into a High Speed Spin. Floor was level, machine was level but it shook like an earth quake.


I was wondering if the rps sensor is going bad or could this be a water level switch issue. There was nothing in the tub when I was testing it?

It could be a bad VRT balance ring on the back of the basket. Those washers will shake for a few seconds, balance out, then go to hi spin.

Mucho umpteen times:)

The vast majority of these will be due to excessive overuse of detergent.

Suds will form inside the Pressure Switch dome & tube---Main Board "thinks" water has not completely drained.

As a result---the drain motor continues to run---while the tub slowly tumbles (waiting for the green light for wide open throttle). Display clock stalls at or around 12 minutes remaining.

Additionally...

Certain older Samsung washers with the VRT (Vibration Reduction Technology) feature can abort the spin cycle---if the temperature in the laundry room is too cold.
 
This was caused by the Main Board "defaulting" on attempting to enter the high speed spin portion of the cycle---due to the Balance Ring ***oil*** thickening (cold).

The correction was to modify the software---to simply allow a longer period of attempting to balance. More time to allow the small steel ball bearings within the Balance Ring(s) to move/travel to the correct position within the ring(s).

Once this occurs---the tub stabilizes somewhat---then the Main Board gives the "go command" for high speed spin.

PITA to know/remember this stuff---ain't it?

Is the remedy to replace balance ring or RINGS (2) or replace the board. I'm sure they probably update the software on the new boards correct?


Thank You for the info. 1st time I'm getting into the VRT Samsung's. Done many Samsungs but no VRT's with Balance Rings.

Replacing the MAIN BOARD resolved the * no spin* complaints (on certain Samsung models---not all).

Again---this symptom was usually seen during the winter months---in cold laundry rooms.

The trend today---is to design MAIN BOARDS with capability of changing/altering software (versions) if needed---by reflashing---using a "jig" and/or WiFi method.


By the way---what was the resolution/answer in this old thread?...
