I think you most likely have a basin Float water level sensor that is no working correctly, the door seal is not water proof, if the water level gets over the lip of the basin it will leak on the floor.

it could be a clogged pump its self,maybe a peice of food or a skin off some thing is hanging up at the last cycle

Remove the epoxy, and clean the area with alcohol. When dry, add a small amount of GOOP adhesive to the area. The door must be left open for at least 12 hours for the adhesive to set enough to prevent sagging. unit should not be used for a total of 24 hours for complete hardening. The GOOP adhesive is available in the glue/adhesive sections of hardware and big box home center stores. As an appliance tech I have used this product for many years on tubs of all types to save my clients from expensive repairs. It holds very well, yet can be removed if need be. As time goes on, you may need to add a little more to cover any additional wear that may occur. Let me know if it worked out for you.

how about putting the washer on some sort of stand so that you can look from underneath and then running it. use a light and observe where the leak is

Good Afternoon Friend, I understand that you are receiving an i30 error code on your Frigidaire dishwasher. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 20-30 minutes. Restore power and start your dishwasher. If this does not correct the i30 error code, I suggest you contact your local authorized technician for further assistance. Hope this is helpful. -Best Regards- WP
