How to fix Jenn-Air MicroClean HE dishwasher error code F3E3 (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on the Jenn-Air MicroClean HE dishwasher error-code chart (via Sears PartsDirect) [1], rewritten for clarity.

Write down the code and model number. Note exactly what the display shows (F3E3) and copy the full model number from the rating label, so you can confirm this chart applies to your microClean HE dishwasher and order the right parts.
Check the drain hose. Disconnect the dishwasher drain hose connection from the air gap or the garbage disposal if you have no air gap.
Run a normal wash cycle. Run a normal wash cycle.
Test and decide. Run a short cycle or restart and watch the display. If F3E3 comes back after these checks, stop using the dishwasher for this function and call a technician, because the remaining causes need meters or part replacement.

The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the Jenn-Air MicroClean HE dishwasher error-code chart published by Sears PartsDirect, rewritten for safe owner use.

When to call a technician

If so, a technician should replace the portion of the drain hose that connects to the drain pump because the check valve in that hose failed.
If water doesn't back up into the dishwasher through the drain hose, reconnect the hose and run the Service Diagnostics Test according to the instructions in the tech sheet.
You should see low soil level indicated during the OWI test in the diagnostic mode.
If you see high soil level during the OWI test, unplug the dishwasher and clean the OWI sensor.
Run the diagnostic test cycle so the electronic control board will calibrate the OWI sensor on the next cycle.
If you still see the error code, a technician should replace the thermistor/OWI sensor.
Anything involving wiring, the control board, the motor or the water valve electrics
The appliance is under warranty: contact Jenn-Air customer support (see your owner's manual) first
