KitchenAid dishwasher F6E3: inlet water: suds or air in pump
F6E3 means the wash pump is pulling in air or foam instead of solid water, which the control reads as too little water in the sump.

What the dishwasher is detecting
The control watches the wash pump's behavior. A pump that is sucking air or suds behaves like a pump that is running low on water, and the control records this code and may add extra fill or wash time.
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 Too many suds: hand dish soap, the wrong detergent, or rinse aid leaking from its dispenser.
- Documented Bowls or pots turned up so they catch and hold wash water.
- Documented Water leaking out of the dishwasher.
- Documented A missing diverter disk in the sump, or a damaged wire harness (named on newer platforms).
Safe checks you can make
- Use only automatic-dishwasher detergent. Hand dish soap, even a small squirt, makes heavy suds that a dishwasher cannot handle; if that happened, run a rinse with the door shut a few times to clear it.
- Check the load: no bowls, pans or containers turned so they catch and hold water, and nothing hanging below the lower rack where it can stop a spray arm.
- Fill the rinse-aid dispenser only to its fill line and wipe up any spill around it; spilled rinse aid can foam during the wash.
- Look along the floor in front of the dishwasher and in the cabinet under the sink for water, and mention anything you find to the technician.
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
- Runs a fill and short wash and checks for sudsing.
- Checks the rinse-aid dispenser for leakage.
- Checks for leaks under the dishwasher.
- Verifies the diverter disk is in place in the sump on platforms that have one.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher detergent dispenser replacement | $180–$370 | Moderate |
| Dishwasher diverter motor replacement | $180–$390 | 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?
Use with caution. If the cause was the wrong soap or a bad load, clear the suds with a few rinse cycles and continue. If it keeps returning, schedule service.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F6E3 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.
