been browsing this forum, and it seems the frigidaire dishwasher pressure sensor is a lemon, how do i remove it?
--------------------------------------------------------------------------------------------------------------:sulkiness::excitement::disgust:

hello

i have a frigidaire professional dishwasher

( http://www.frigidaire.com/Owner-Center/Product-Support--Manuals/?productCode=FPID2497RF)

problem=the drain pump runs continuously, even with the door open and the dishwasher sump empty.

background, the dishwasher finished a cycle normally. i opened the door, emptied dishes. then, a half hour later the

drain pump just turned on despite the door being opened the no water left in the dishwasher.

i turned off the power using the breaker for a half hour, filled the sump with a half liter of water to see if it was

leaking out, and it wasnt, flipped the breaker on, sump emptied and the pump once again

continued to run . i removed the kick plate and didnt see any water on the floor under the dishwasher. Note, i even

pressed the "start/cancel" button for 10 seconds and that did not do anything.

***************there is an error code 30 which is identified as a leak or overflow of water has been detected in

the bottom of the pan.

i have found similar issues with other dishwashers and the advice was to pull the unit out and tip it forward or

backward to empty the water from the pan (and on to the floor). the other solution that was posed was to clean out

the pressure sensor as it was know to get gummed up with grease.

why would the sump drain pump run if there was water in the drip pan?

>>>>>>>>>>>HOW DO I REMOVE THE PRESSURE SENSOR? PLEASE PROVIDE DIAGRAMS<<<<<<<<<<

is there a way to inspect the drip for leaked water and use suction to remove it?

advice?

Hi,

I'm not able to locate the service manual for this model, but if your are getting the error code i20 or i30 then you will need the pressure sensor kit below, it does come with instructions that show and tell you how to replace it.

just wondering, how could a pressure sensor connected to the sump be able to detect water that has leaked into
the drip pan under it? is there any type of sensor in that particular unit that can? i have been told that my unit does not have a float switch. how does the computer determine that there is water in the drip pan at all?

Frigidaire designed this that way, why? I don't know, I don't have the theory of operation on this newer design Frigidaire, seems a odd ball way to do it too, that's why I never recommend Frigidaire products to my customers.

I'm just pointing you to the part that will fix this error code you're getting, per others with this same error code, that this kit fixed theirs with.

I have a Frigidaire Gallery FGID2477RF dishwasher that was displaying the same spurious i20 error. The pressure sensor was indeed the problem, but in my model, it is separated from direct contact with the drain water by an air-filled tube.

The food blockage was in this tube, and cleaning it eliminated the errors.

The pressure sensor itself was clean. I cleaned the tube by pulling the dishwasher out and looking for the pressure sensor from the left side, after pulling the insulation aside. In retrospect, it may be possible to perform this cleaning without pulling the dishwasher out, by inserting a pipe cleaner into the ~ 3/8" hole in the base of the tub near the drain, after removing the filter.

Scrubbing first few inches of the tube with a pipe cleaner should do it, and you won't be touching the pressure sensor, which is a few inches past that, around a bend.

I ordered this Pressure Sensor Kit 5304504077 to put in my Frigidaire Gallery dishwasher that has been failing to complete the cycle, except on rare occasions, for some time now, giving the Error 20 message. My problem, newbie that I am, is that I can't seen to locate the old pressure sensor. How do you access it?

Hi,

The new Pressure Sensor Kit comes with complete instructions, did you not get the instructions when you received the new one?

Sensor

Thanks for your reply. Yes, I got the instructions, and I was finally able to locate the old sensor. Still having a little trouble switching it out, though, partly because the space to work in is so cramped. Currently I'm just accessing it from the opening at the bottom of the left side of the dishwasher. Is one of the other panels (front, back, or bottom) supposed to come off?

Pull the dishwasher out a little bit so you can get to the left and right sides as needed, it doesn't come with panels unless you have a portable dishwasher.

Sensor Pressure

Okay, thanks. I ended up just cleaning the filters, cleaning the old sensor, etc. and it completed a whole cycle without stopping, but I'm sure it'll start messing up again soon. When it does, I'll at least have a little better idea how to go about changing it out.

Hi you sound knowledgeable Jake, thank you. I have a Frigidaire Gallery dishwasher, Mod FGID2474QF3B. Same i20 code. I have done some tests and am 99% sure it is not the filters, drain line, or pump, but that it is a problem with the pressure sensor. My challenge is that the previous homeowner installed this dishwasher, and then a new wood kitchen floor over the old floor without removing the old floor. Therefore, I can't pull the dishwasher out without disassembling a good portion of the new kitchen floor. I'm willing to do just about anything to clean or replace the sensor with the dishwasher in place.

A couple of questions:
1) Any more suggestions on cleaning the sensor by accessing the inside of the tub only? It seems the sensor comes with a clear plastic waterproof cover. I've tried scrubbing with toothbrush. I've tried letting vinegar sit overnight in the tub and then drain. Another thread suggested inserting a pipe cleaner into a hole in the tub that I gather leads to the pressure sensor.
2) Do you think it is possible to replace the sensor without removing the dishwater?
3) Long shot, but is there any way to 'defeat' the sensor, in other words, make the dishwasher unaware of its existence so that i20 is not possible.

Thanks, Garrett

Hi Garrett,

You may want to try what Bruce said to do here first: FGID2474QF3B My fix to the i20 error code

If that does not fix it, then you'll need to order the pressure switch kit. Unfortunately there's no other way to replace it, or clean it thoroughly, other than pulling the dishwasher out.

Here's the pressure switch kit for your model:
5304504077 Pressure Sensor


It does fix this problem.
