Admiral dishwasher F3E3: owi: failed calibration
F3E3 means the optical soil sensor (OWI) could not calibrate itself against clean water, so the control cannot judge how dirty the wash water is.

What the dishwasher is detecting
After service diagnostics or on a calibration cycle, the control expects the OWI sensor to see clear water. If the light reading through the water is outside the expected range, calibration fails and this code is stored.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A failed OWI sensor.
- Documented The OWI lens coated with hard-water film or food soil, so it cannot see clear water (named on newer platforms).
- Documented A drain check valve that leaks, letting dirty water run back into the dishwasher after draining so the 'clean' water is not clean (named on older platforms).
- Documented A poor connection in the soil-sensing circuit.
- Possible General service knowledge, not from the service documentation: very hard water, as in Las Vegas, builds film on the sensor lens faster.
Safe checks you can make
- If your model has a removable filter in the bottom of the tub (the owner's manual shows how to twist it out), take it out, rinse it under the faucet and lock it fully back in place.
- After a cycle, look for dirty water sitting in the bottom of the tub. A small amount of clear water around the filter is normal; murky water that returns after draining is worth reporting.
- Run an empty cycle with an automatic-dishwasher cleaner to remove hard-water film from inside the tub.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the OWI reading in service diagnostics with clear water.
- Inspects and cleans the sensor lens.
- Tests whether drained water flows back through the drain hose check valve.
- Runs diagnostics after any sensor work so the next wash recalibrates.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher thermistor or turbidity sensor replacement | $180–$330 | Light |
| Dishwasher drain pump replacement | $180–$400 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Generally safe to keep using. The dishwasher keeps working; cycle choices that depend on soil sensing may run longer than needed until it is fixed.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F3E3 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
