Frigidaire dishwasher UO code /  Frigidaire gallery dishwasher UO code

This simply means the vent is open (vent not closing)- and it could be brought about by myriad issues including a fan(vent assembly) that’s not working.

Typical behavior here is your dishwasher starts filling with water after you start a cycle.

Then, the vent assembly clicks a couple of times and then your dishwasher stops and throws the error code(on the LED).

Also, you may note water is not draining from your dishwasher and it is not getting items clean.

If you’re getting the notorious Frigidaire dishwasher fault code UO, try to replace the fan assembly(it could be defective hence the UO code on Frigidaire dishwasher).

That could do the trick- and it’s a really easy install!

Check the current price of a replacement Frigidaire dishwasher vent assembly.

Quick Tip: Try the above fix if you’re struggling with the Frigidaire Dishwasher Error Code UF (ER/uF indicates the fan is not running)


Frigidaire dishwasher i 40 error code / Frigidaire dishwasher i20 error / Frigidaire dishwasher i30 fault code / Frigidaire dishwasher error code i30  / Frigidaire dishwasher error code 30

What it means:

You have a bad pressure sensor(pressure sensor switch) so you might notice that the drain pump in your dishwasher keeps running(and running) and the appliance won’t move to the next washing step.

How to resolve the code

It is recommended you change out the faulty pressure sensor switch (Check price at Amazon).

Keep in mind that this is the part you probably need to change out if the Frigidaire dishwasher i20 error code and Frigidaire dishwasher i30 fault code are giving you sleepless nights.

It oftentimes works like a charm(Once you get the new part in there) so try and see how it goes.

But it’s also worth trying to clean filters….  and then leave the appliance unused for several days.


Error code i30 could also mean there is a leakage and water has overflown into the bottom tray and therefore, the anti-flooding device has been automatically activated.

Now, many times the culprit is dirty filters so do not forget to give cleaning them a shot- it could save you a few bucks.

I should add that adding too much detergent could also make it overflow with suds, leading to the Frigidaire dishwasher error code 30 (pump will incessantly run)..

Here just grab a Shop Vac then vacuum off the water completely – unplug it from power completely before and also cut off water- reconnect after you’re done and check if the i30 still shows.
