What Does Error Code i30 Mean on a Frigidaire Dishwasher?

Leak detected in base.

Water has reached the base pan and tripped the anti-flood float switch, so the dishwasher stops and runs its drain pump continuously to protect against a leak. A torn door seal, oversudsing, a loose internal hose, or a cracked tub are the usual causes.

Frequently Asked Questions

Can I keep using my Frigidaire Dishwasher when error i30 appears? +
It is not advisable. The dishwasher may still power on, but running it while i30 is active can worsen the leak fault or damage related parts. Treat it as a soon-as-possible repair.

i30 keeps coming back after a reset — what should I check next? +
A reset only clears the stored i30 fault; if it returns, the leak problem is still present.
