Jenn-Air Dishwasher Error Code E:14

E:14 means the control board is receiving no pulse signals from the flow sensor even though the heat pump circuit has detected water inside the machine. The flow sensor uses a reed switch to generate impulses that confirm water is moving through the system. When those impulses are absent, the dishwasher stops the current programme and drains as a safety measure. The fault points to either the flow sensor itself or the wiring connecting it to the control board.

The dishwasher stops the cycle and drains automatically when E:14 is triggered, so it is not actively running in a compromised state. However, the underlying fault means the machine cannot reliably monitor water flow, and continued attempts to run cycles without resolving the issue are not recommended. It is best to diagnose and repair the fault before using the appliance again to avoid potential issues with wash performance or water management.

If the fix is simply reseating a loose connector or cleaning corroded terminals, there may be no parts cost involved, with any expense limited to a service call if you use a technician. If the flow sensor reed switch needs replacement, parts typically range from around $20 to $60 depending on the specific component, with professional labor adding $75 to $150 or more depending on your location. A full repair including parts and labor for a sensor replacement generally falls in the range of $100 to $200.

Start by inspecting the wiring harness and connectors leading to the flow sensor for any loose, corroded, or broken connections and reseat or repair as needed. Next, test the flow sensor reed switch directly using a multimeter to check whether the switch toggles when water flows across it. If the wiring is intact and the sensor does not respond correctly, replacing the flow sensor is the standard repair. Cleaning any debris or scale buildup around the sensor mechanism is also worth attempting before committing to a part replacement.

A reset may temporarily clear the error code and allow the dishwasher to attempt another cycle, but if the flow sensor or its wiring is genuinely faulty the code will return once the control board fails to detect impulses again. Resetting is useful as a first step to rule out a one-time glitch, but a persistent E:14 code requires physical diagnosis and repair of the sensor circuit to resolve it permanently.
