Okay I need help.

Our 2017 Frigidaire Gallery Professional dishwasher started giving the i20 error and not draining.

I jumped on here and started to realize that the problem is usually a clogged pressure sensor. And that there was an updated sensor kit that generally solved the problem.

Here’s where im at.

1. First I removed the Original sensor and attempted to clean it. Nothing of note came out. Eventually I pushed a a w tip far enough in to hear the drain pump kick on. Put it back in and ran two rinse only cycles. Success. One wash cycle with dishes. Success, second wash cycle. I20 error. Not draining.

2. Ordered the updated pressure sensor / kit, at which point I discovered that my washer had an air trap built into the basin, and that the only part of the kit that was applicable was the pressure sensor. The “modification” was not required on my dishwasher. Replaced sensor with new one, started a rinse cycle, i20 error. No good.

3. Decided to pull sensor out before manually draining basin to confirm the factory air trap was not clogged. Outcome: water flowed freely from the hole the sensor is connected to so no clog / restriction there. Also, I made a mess of the kitchen.

When it did work after step 1, and when the pressure sensor was disconnected you can clearly hear the drain pump run and the dishwasher did drain.

So so far we know that:

1. The pressure sensor is getting water so it should be activating.
2. The new sensor has never worked (could it be the wrong one??) I noticed that the old sensor utilized a rubber seal between the sensor and the outlet on the basin, the newer sensor does not, but the plastic is thicker. It attached fine and the electrical connection clipped right in.
3. The drain pump works properly when it is activated.

Help!!!

This is the pressure sensor I show for your model: https://www.repairclinic.com/PartDetail/Pressure-Switch/A00055408/4840951

Look at this thread and do what he suggested:

FIXED - FGID2474QF4B Frigidaire Dishwasher Pressure Sensor Redux

I've drilled down on all the previous Frigidaire pressure sensor discussions, including this one: https://www.applianceblog.com/mainforums/threads/frigidaire-gallery-i20-error-troubleshooting-advice.62723/ And it seems that the common advice is to get the kit...

But then I cleaned the passage from the sensor to the sump using a pipe cleaner. A lot of gunk came out and it has now been working for several was cycles.

I have tried the pressure sensor you mentioned (as part of the update kit)

Air trap to pressure sensor is clear.

Here where things get weird.

1. The old prsssure sensor works intermittently. What I mean by this is you can get 2-3 cycles out of it before the i20 error re appears. I actually got 3 successful rinse cycles in a row with the old sensor back in the machine yesterday.

2. The new pressure sensor has NEVER worked and managed to complete even a basic rinse cycle.

3. I’ve discovered that toggling the circuit breaker seems to “reset” the machine and it works for 2,3 sometimes cycles before the error re appears.

Operation is random. When it does work, it works fine. There is not ONE consistent failure. If it completes a cycle and drains. When it fails, i20 error and a pool of water at the bottom of the machine.

I’m starting to thing that the problem is somewhere in the electronic controls. The error is not consistent and everything works “sometimes “

The oh it’s the pressure sensor theory may be correct on older ones but the solution from the manufacturer is installing the air trap to prevent fouling of the sensor. (As part of the upgrade kit) my dishwasher has the air trap built into the tub and fouling of the sensor seems to be much less likely, plus a thorough cleaning of the old sensor produced no visible dirt / gunk.

I can pretty consistently get a cycle or two out of it by resetting the breaker and returning the machine to a new power on state.

If it was a sevsir or drain pump or some sort of mechanical failure it wouldn’t work sometimes? Like a bad drain pump would be a bad drain pump. A clog would be a clog until cleared.

Seems like my trouble is in one of the logic control systems that cause the machine to believe something is wrong and display an error rather than continue with the cycle.

I don’t know how much further into this I can get. Replacing the logic board seems not worth it on a 6 year old dishwasher that has developed problems as it is over half the cost of a replacement.

I’m just thinking out loud here and trying to eliminate the obvious stuff.

Thanks!

Ok George, that's a lot going on here with your machine, its very difficult to troubleshoot these multiple issues just on the forum here, I would need to come to your house to see what's going on.

2. The new pressure sensor has NEVER worked

That seems like a defective pressure sensor to me, where did you get it at?

 

[geoandroulakis]

Yeah, I’m stumped.

Got the kit online, after reading about it heres, it seemed to solve most i20 error issues. Cake with sensor air trap I didn’t need a hose and some gaskets. Here is new v/s old sensors.

To be fair I only had the new sensor installed for a day because it became apparent that replacing it was not the solution to my problem. Could it be defective? Possibly…

[Jake]

Yes, it could be defective. Contact the place you got it from and they should be able to send you another new one.

 

[Luke Finley]

After replacing the pressure sensor did you clear the error codes and run the calibration cycle? Also double check the high loop on the drain line. It needs to have essentially a P Trap in the drain line just before the disposal or that problem can creep up from time to time.

 

[Jake]

Thanks Luke for adding that.
