Dishlex 302 model is displating "i30" error which

Hello Roberta, I appreciate your submission!
Based off the information you have provided me your Frigidaire dishwasher is displaying an error code of "I30". Error code "I30" means you could be experiencing an issue within the aqua control, which means it could be your water valve, water line, or control panel. You may need to reach out to your manufacturer for additional assistance. I hope this information is helpful. -Matt

Hello friend, I appreciate your inquiry!

Based off my understanding your dishwasher is displaying an error code of I30. An I30 error code means this could be an issue with your aqua control. I would suggest performing a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. If you continue to receive an I30 error code after the reset I would recommend having a professional technician out. This will help you avoid any unnecessary part purchases. Hopefully this information is helpful to you. -Matt

For some reason I can't find my manual for my Kenmore dishwasher, but I woke up this morning to find my that it didn't drain and an E25 error code. The last rinse didn't drain.

If you have hard water, you should reduce the amount of detergent you use. Here's a map showing water hardness in the USA. http://www.citriclean.net/why-citriclean/

Yes, mine were successfully RESET from the error code SC:552 and SC:302. Machines runs good, but i about to wander what could be faulty inside, it took one month after error code 302 exist. Mine was exactly DSM615 same model same error code 302 (this is really 302) which resolved by reset. Hopefully machine will run good for two months.
To RESET it
1. Press Yellow button
2. Press 1, 0, 7
3. Hold Orange button for 3 seconds
4. Select MODE 5
5. Select Clear Memory (or something like it) (801)
6. Select 002-Engine
7. Select EXECUTE
8. Turn the switch off and leave it for a minute
9. Turn back machine On.
10. Done, or else there could possibly something else.

Good Luck....

The FL error code means:
Flood Condition:
FL flashes if any overfill condition occurs. This condition occurs when excessive water in the tub causes the overfill switch to trip. The control must realize that the trip was due to an overfill condition instead of a suds lack condition in order for FL to be displayed

With an overfill condition, the beeper repeats a warning every 10 seconds with no time-out. The pump is cycled in drain mode for 30 seconds on, 30 seconds off until the overfill switch resets or power is discontinued to the unit.

Press STOP/CANCEL to clear the display.

This problem I see on these are the water pumps getting clogged with lint or other things, causing the pump not to pump all of the water out at times.

There is a check "valve" in the drain assembly that seems to sometimes cause problems with the FL error code. You can remove this piece, and might avoid changing the pump.
