Kenmore Washer Error Code F43

F43 on a Kenmore washer indicates a steamer inlet valve failure. The code is triggered when the steamer valve or flush valve is detected as blocked open or not functioning properly. The washer halts the cycle until the fault is resolved. Diagnosing the issue starts with testing the valve for continuity, where an infinity reading confirms a failed solenoid coil.

It is not recommended to continue running the washer when F43 is active. A valve stuck open can allow uncontrolled water flow into the steam system, which may cause leaks or water damage. The machine typically stops the cycle automatically when this code appears, so normal operation will not resume until the fault is addressed.

Resetting the washer by unplugging it for a few minutes may temporarily clear the F43 code, but the error will return if the underlying valve or wiring fault has not been repaired. A reset does not fix a failed solenoid coil, a blocked valve, or damaged wiring. The fault must be diagnosed and corrected to permanently resolve the code.

A knowledgeable DIYer can often resolve F43 by testing the valve with a multimeter and replacing the faulty component. Start by checking the solenoid coil for continuity and inspecting the wiring harness for damage or loose connectors. If the valve tests as an open circuit (infinity reading), replacing the valve assembly is the likely fix. Always unplug the washer before beginning any inspection or repair.

If the repair involves only a replacement steamer or flush valve, parts typically range from $30 to $80 depending on the specific model, with professional labor adding $100 to $200 on top of that. If the wiring harness is the issue, costs may be lower since no parts may be needed. A control board replacement, if required, can run significantly higher, in the $150 to $350 range for parts alone.
