JennAir Dishwasher Code F1E2: Main control communication lost

What F1E2 means

Several JennAir dishwashers on the current platform, for example the JDTSS247HS and the JDAF3924RX, display F1E2 when the main control reports a communication error. Parts of the control are not talking to each other the way they should. The cycle stops or will not begin. The first step is to cycle power, which clears a temporary loss of contact. Nothing in the tub itself is the cause.

Common causes of F1E2

Communication between the main control and another board interrupted
Loose or damaged connection inside the control area
Main control failing and needing replacement

✓ One safe check you can try

1. Open and shut the door, then press Cancel. 2. Restart the appliance's power by tripping the breaker off for sixty seconds. 3. Try a short cycle. 4. If F1E2 reappears, stop and schedule service. Do not remove the lower kick panel or pull any connectors.

! Why to stop there

Communication problems come from boards and wiring that owners cannot see.
Reseating a connector with the power on is a shock risk.
A power cycle can only hide a connection that is truly failing.
We trace the failing link and give you a written price first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F1E2F1E2 questions

What does a communication error mean?

The main control and another board in the dishwasher exchange signals. F1E2 says that exchange stopped. A power cycle restarts both, which can fix a brief interruption.

Is F1E2 the same as F2E2?

They share wording about main control communication but are different codes with different prefixes. We read which one your machine shows and test the relevant link.

Will my dishes be ruined?

Unfinished dishes can be rerun after the repair. If you find water in the tub, run Drain if available or call us. Quotes are always in writing.
