Samsung Washer 4C & Ur Error Codes (Model WA52M8650AW/A4): Causes, Fixes & Expert Repair Tips
If your Samsung top-load washer (WA52M8650AW/A4) repeatedly displays 4C and Ur error codes during the rinse cycle, you’re not alone. These two errors often occur together because the washer isn’t receiving enough water or can’t balance the load properly.
At Alliance Appliance Services LLC, our licensed and insured technicians diagnose these issues every week. Here’s what these error codes mean, the most common causes, and when it’s time to call a professional.
What Does the 4C Error Mean?
The 4C error means the washer isn’t filling with enough water within the required time.
Common Causes
- Clogged water inlet valve
- Weak water pressure
- Faulty water inlet valve
- Kinked or partially blocked water hoses
- Dirty inlet screens
- Defective pressure sensor
- Wiring issue
- Failed main control board
Since you’ve already checked the hoses and mesh filters, the problem is likely inside the washer.
What Does the Ur Error Mean?
The Ur error indicates an unbalanced load.
Normally this happens because:
- Clothes are bunched on one side
- Suspension rods are worn
- The washer isn’t level
- Water didn’t fill correctly because of a 4C issue
When the washer can’t add enough water, the load becomes uneven during rinse and spin, causing the Ur error.
Why Both Errors Appear Together
This is actually very common.
The sequence is usually:
- Washer starts rinse cycle.
- Water doesn’t enter properly.
- Tub doesn’t reach the correct water level.
- Load shifts unevenly.
- Washer displays Ur.
- Eventually displays 4C.
So in most cases, the 4C error is causing the Ur error.
What Should You Check?
1. Water Pressure
Make sure both hot and cold water valves are fully open.
Samsung recommends around 20–116 PSI.
2. Water Inlet Valve
This is one of the most common failures.
Symptoms include:
- Slow filling
- Stops during rinse
- Buzzing sound
- 4C error
A technician can test the valve with a multimeter and replace it if defective.
3. Pressure Sensor
The pressure switch tells the control board how much water is in the tub.
If it sends incorrect readings, the washer may stop filling even though the tub isn’t full.
4. Suspension Rods
If your washer shakes excessively or the tub bounces easily, worn suspension rods may trigger the Ur error.
5. Drain Pump
A partially clogged drain pump can leave water in the tub and interfere with the rinse cycle.
6. Main Control Board
If every other component checks out, the control board may not be sending power to the inlet valve correctly.
Why the Top Panel Won’t Come Off
On the Samsung WA52M8650AW/A4, the top panel doesn’t simply lift.
Many people remove the rear screws, but the panel is still held by:
- Front locking clips
- Side retaining tabs
- Hidden locking hooks
Forcing the panel upward can break the plastic clips or damage the top assembly.
If it won’t release after following the service manual, it’s best not to pry harder, as repairs can become much more expensive.
