Frigidaire FFTW4120SW Washer Problems & Error Codes — Overview
The Frigidaire FFTW4120SW is a top-load washer that shares diagnostic and error code structure with other models in its series. The most frequently documented issue on this unit is the E3/FD error code, which points to a lid lock assembly failure. When this fault occurs, the lid will not lock, stay locked after the cycle ends, or produce repeated clicking noises as the mechanism tries to engage. The machine will not start or complete a cycle until the lock assembly operates correctly.
Other faults that appear on this model include out-of-balance conditions (E4 code), drain issues, and control board glitches. The FFTW4120SW uses a diagnostic mode accessible through a button sequence to help pinpoint which system is failing. Most repairs involve straightforward component replacement once the fault code narrows down the cause.
Most Common Problems on This Model
- E3 or FD error code with lid not locking or staying locked The lid lock assembly has failed mechanically or electrically, and the washer will not start or finish the cycle until you replace the assembly (part 5304511338).
- Clicking noise at the lid lock with no cycle start The lock actuator inside the lid lock assembly is cycling on and off but not engaging the strike, so you need to replace the entire lid lock assembly.
- E4 error code and washer stops mid-cycle An out-of-balance condition has triggered the fault, often caused by overloading, uneven load distribution, or a failed impact switch that detects basket movement.
- Washer fills but will not agitate or spin A stuck lid lock assembly, failed motor coupling, worn drive belt, or bad control board can prevent the basket from moving even though water is present.
- Lid lock stays engaged after cycle ends and door will not open The lid lock assembly has failed in the locked position, and you need to manually release it or replace the assembly to restore normal operation.
- Washer does not drain or leaves standing water Check the drain pump for clogs or a failed pump motor, and inspect the drain hose for kinks or blockages that prevent water from leaving the tub.
- No response when pressing buttons or display is blank Confirm that the unit has power at the outlet, then check for a tripped breaker, loose wiring harness at the control board, or a failed main control board.
- Excessive vibration or walking during spin Level the washer on all four corners, redistribute the load evenly, and inspect the suspension rods and shock absorbers for wear or damage.
Parts That Commonly Fail
| Part | Notes |
|---|---|
| Lid Lock Assembly (5304511338) | Amazon | Fails with E3/FD code; causes clicking, no lock, or stuck lock. |
| Impact Switch | Amazon | Detects out-of-balance basket movement; triggers E4 code when faulty. |
| Main Control Board | Amazon | Can cause no-start, erratic behavior, or false error codes. |
| Drain Pump | Amazon | Clogs or motor failure leave standing water in the tub. |

When to Call a Pro
Call a technician if the washer shows error codes you cannot clear through a power reset, if you are uncomfortable working with live 120 V AC wiring, or if you have replaced the lid lock assembly and the E3/FD code persists. Also bring in a pro when the control board or wiring harness is suspect, when the washer requires disassembly of the basket or transmission, or when you lack the tools to safely tip the unit for access to the bottom-mounted components. If the machine is still under warranty, contact Frigidaire or an authorized service center before opening any panels.
