What F2-E2 means on your Jenn-Air dishwasher
The F2-E2 code on a Jenn-Air dishwasher is generated only when the control logic detects a defined condition it can name. The Jenn-Air F2-E2 error means uI Communication Fail — The F2-E2 error code on Jenn-Air dishwashers indicates communication between the user interface board and the main control board has failed, described in the control board’s own diagnostic language.
This particular fault tends to appear when the ribbon cable connecting the user interface to the main board has come loose from door flexing. The two boards cannot exchange data, which is worth knowing before you start troubleshooting.
Fault codes like this exist so a technician (or an attentive homeowner) doesn’t have to guess blindly — the dishwasher’s control board has already narrowed the search considerably. Keeping a note of when the code first appeared, and under what conditions, gives a technician a real head start on diagnosis. Ignoring a recurring code rarely makes it resolve itself, and in some cases it can let a minor fault progress into a more expensive one. Because these boards are designed to fail safe, a persistent code usually means the safety logic is doing its job by preventing further operation until the fault is addressed. Catching this early, before secondary damage sets in, is usually what keeps a repair simple and inexpensive relative to letting it run.

Symptoms
- The display shows the f2-e2 code (ui communication fail)
- a new cycle refuses to start no matter which button is pressed
- the machine stops before the dry phase, leaving dishes wet
- controls go unresponsive until the fault code is manually cleared
- the tub fails to drain, or drains at the wrong point in the cycle
Common causes
- Loose ribbon cable — The ribbon cable connecting the user interface to the main board has come loose from door flexing.
- Failed user interface board — The board behind the control buttons has a component failure.
Troubleshooting steps you can try
Start with the basics — these steps address the most common F2-E2 triggers:
- Power cycle the dishwasher. Turn off the breaker for 5 minutes, restore power and test. Opening and closing the door repeatedly can loosen the ribbon cable over time.
- Check door panel connections. If comfortable, remove the inner door panel to inspect the ribbon cable connection between boards. The cable connector should click firmly into place on both ends.
When to call a technician
Consider F2-E2 beyond DIY repair once you notice any of these:
- Ribbon cable shows physical damage
- Interface board has no output
- Connector pins are corroded
As for whether the F2-E2 error clears on its own: A reset may restore communication temporarily if the cable is intermittent. A dishwasher that keeps producing F2-E2 after every attempted fix has told you, in effect, that the part needs replacing.
A diagnostic visit for F2-E2 on a dishwasher usually starts with the technician confirming the fault with the built-in test mode, then checking voltage and continuity at the component most often responsible before recommending a fix.
