Kenmore Washer Error Code F34

F34 indicates an analog pressure sensor failure detected by the steamer electronic board. The board monitors pressure within the steamer system via an analog sensor, and F34 appears when that sensor's signal is absent or out of range. The most frequent cause is a pressure hose that is loose, kinked, or blocked rather than a failed sensor.

It is generally not advisable to continue using the steam function while F34 is active, as the steamer system is not operating with reliable pressure data. Non-steam wash cycles may still function depending on the model, but running the steamer under these conditions could potentially worsen the underlying fault. Diagnose and resolve the issue before relying on the steam feature again.

A reset may temporarily clear the F34 code, but if the underlying problem with the pressure hose, airtrap, or sensor has not been resolved, the code will return as soon as the steamer system is activated again. Clearing the code without fixing the root cause does not repair the fault. Perform the physical inspection and any necessary repairs before attempting to reset and test the washer.

Start by locating the pressure hose connected to the steamer assembly and confirming it is firmly attached at both ends with no kinks or pinching. Next, inspect the airtrap and the hose interior for any blockage from mineral deposits or debris and clear any you find. If the hose and airtrap are clear and properly connected, the pressure sensor or steamer board may need to be tested and replaced by a technician.

If the fix is simply reseating or clearing the pressure hose and airtrap, there is no parts cost involved. Replacing the analog pressure sensor typically runs in the range of $20 to $60 for the part, plus labor if a technician is needed. A steamer electronic board replacement is more costly, generally ranging from $80 to $200 or more depending on availability and the specific model.
