What the dishwasher is detecting
The flow meter reports any water passing. Flow while the valve is supposed to be closed sets this code. The dishwasher then runs repeated drains to remove the extra water.
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 fill valve stuck open mechanically, so water enters even with the door open or the unit off.
- Documented A shorted fill valve switching part (triac) on the control; the documentation points here when the control code is also stored.
- Possible General service knowledge, not from the service documentation: Las Vegas valley water is very hard, and scale or sediment can slowly restrict the small inlet screen at the water valve.
Safe checks you can make
- If water keeps entering the tub with the door open or the dishwasher off, turn off the dishwasher's water supply valve under the sink.
- Do not interrupt the automatic drain that follows this code by restarting cycles or cutting power; the documentation warns this can lead to an overflow.
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 whether the dishwasher fills with the door open, which points to the valve.
- Checks the history for the control code, which points to the control instead.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher water inlet valve replacement | $180–$360 | Light |
| Dishwasher main control board replacement | $260–$590 | 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?
Stop using it until it is checked. Stop using the dishwasher. Let the automatic drain finish, then shut off its water supply and schedule service; a valve that will not close can flood the kitchen.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most F8E5 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.
