Exactly the fix I needed. I didn’t even bother pulling out the dishwasher and checking the heating element. I purchased the flood switch assembly on Amazon and a 1/4” hex screwdriver with magnet and fifteen minutes later the repair was done and after running a full cycle I can verify that the heating element is again functioning! I could tell upon comparison the old and the new that the float was stuck and highly probable that this was the problem. Thanks so much for the video!
I had this same problem in my GE dishwasher. I thought it might be the heating element, since that's the usual culprit, but when I checked it with a multimeter it was fine. I was able to order the flood switch and the install was quick, easy, and cheap. My landlord even took $200 off the rent because I saved him the cost of having to buy a new dishwasher.
This is the first model dishwasher I’ve seen with the float location in the sump. Also the first I’ve seen that the float switch is in the heating circuit. Interesting. Thank you for this very informative video. Well done!
Yeah I replaced $150 control board thinking it was gonna fix it. Well, it didn't and now I'm going back to the customer's house to replace the flood switch. Customer complained that it didn't heat anymore
Thanks for the tip, I was convinced that I had to replace the heating element before I saw your video. Replacing the flood switch took about 10 minutes and fixed the issue.
If at the end of a dishwasher cycle your dishes are filmy and plastics on the top rack don’t dry well- Open the door mid cycle and see if you don’t see steam when you open the door. This is a fix that worked for me. Just replaced mine today and I had steamy water when I opened the door midcycle and my dishes were clean without the film and greasiness, hot and dry after at the end of the wash 👍
Thank you for this great video. I didn't turn my water off or the breaker to the dishwasher. Watched your video and had my flood switch changed out in no time and now my $5.00 dishwasher works perfectly!
I noticed that when you took the old flood switch out, I didn't hear it rattle. And when you started to install the new one, I heard the float rattling around. From the looks of the old one, that food did a number of blocking the float. Good video by the way!
I should have checked it out more, including cleaning it and doing meter checks. It was so inexpensive I just swapped it and was glad that it worked. Thanks for watching and for the feedback!
Thanks for the video. I appreciate how you get right down to business & no standing around spankin it while telling me a bunch of nonsense. Just FYI, its a FLOAT switch, not flood switch.... I only mention it for part ordering purposes.
You're welcome. The part that I ordered and received show as a flood switch. You can see it briefly at 0:23. Float switch does sound like a better name for it or maybe anti-flood, but that is what they called it.
Wish I had found this video a few days ago to fix my no water problem. All the videos I found showed the float of to one side. I needlessly bought a control board and tried to unscrew what I learned later was the float switch ripping the wires apart at the connector. Not until I stuck my head in there I found the 2 screws that hold the retainer ring. As soon as I pulled out the switch assembly and saw the wire connector I then knew what it was. The float inside must have been stuck up as I never could see voltage at the water valve. It must have come free when I removed it . I soaked it in vinegar while I removed the wire harness to repair the wires I destroyed. Pulled the wire pins from the connector and was able to solder the wires back on to the stub of the broken wire still on the pins. I epoxied the wires together up to the connector just to insure they would not touch where I soldered them. Put all back together and success ! ..Anybody need a control board??
I bought Model GDF630PSM4SS in September. It stopped draining after two weeks. The technician who was sent told me that the problem was that I bought GE Dishwasher in the first place. Not kidding! He told me he would buy a Bosch as all GE dishwashers are junk. It broke a week later and for the next 3 weeks I had to bail it out by hand, let it sit a day, and then it would work again for about 4-6 times. The 2nd technician ordered a part that did not need to be replaced, got it to work and then it failed again and would not drain. I had to buy a new dishwasher and the GE sits in my garage. GE told me they will not refund the money and would only replace it if the technician states in cannot be fixed. Stay away from GE.
I have a GE and it is great. Yeh needs a little maintenance now and then but overall very happy with it. Dishwashers are super easy to fix by doing it yourself. I have heard equally bad things about Bosch dishwashers. I love my Bosch power tools but don't have any desire to own a Bosch dishwasher for some reason
It is pretty much impossible to show that in such a tight space, but if you pull the dishwasher out and lay it on the side it is very easy to see the connector from the bottom. It has a little tab on it that needs to be pushed in to release it. You can see what I am talking about in another video that I have posted here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-14bYL6fFDAE.html at the five minute mark.
I replaced the flood switch on mine. U can hear the.float move in the new part. When i pulled the old one out it was so clogged the float wouldnt move. My filter was gross too. Cleaned everything up put it back tkgether hoping it works. Sucks i already replaced the heating element. Replacement parts sure arent cheap. Running a test load of dishes now...fingers crossed. Thanks for posting.
Thanks to this video and ones like it I replaced this part flood switch and it fixed all of my symptoms stuck in drain mode each cycle running for few seconds then shutting off no water input no drain fixed all of them thank you!
We have the same GE dishwasher I got 7 years ago. About 4 years ago it flooded and GE sent out (free - even though it was out of warranty) a control module (the one at the bottom, not behind the top panel). That worked, but the other day it flooded again (water not draining). The filter itself was pretty dirty and a couple days before I have put in a BBQ grill sheet that was pretty crusty so there was a lot of debris in the water sitting at the bottom of the dishwasher pan. I took the filter out, etc. and saw the flood switch was just impacted with “stuff”. I hose it out but I think it’s best that I get a new one. Hopeful that works and I don’t have to replace the control module again.
If the plunger is stuck, you can try cleaning it and save $40 on the part. You should feel something inside move when you shske it. After replacing the sensor, I got my old one to work by digging the gunk out with a screwdriver, forcing water in with a hose sprayer, and soaking in a vinegar solution . Don't soak the rubber gasket end, or it may leak. The plunger passed the shake test, and a multimeter showed it was working in the up and down positions. The plunger didn't move nearly as freely as the new one, so I didn't bother testing it in the dishwasher. It should work based on the test, but may gunk up soon after.
Replaced flood switch, which old one didn’t have ball thing moving around. Ran dishwasher and still doesn’t dry dishes. My old dishwasher was steaming hot when done. This one isn’t even close to being hot. Guess I try heating element next.
Is there no check for the sensor? I have a GE dishwasher that is not heating. Need to pull it out and check continuity. When I moved in, the fine filter was covered in scale completely. I ran a cleaner through the washer after scraping off the majority of scale from the filter. Thinking about it, this sensor could be covered in scale as well. Hmm.
If it is a simple switch it should be off or on depending on the float position, so off would be no continuity, on would be continuity. I haven't pulled mine to look at it. Trying to see if I can find a test.
Hi. How do you check before buying flood switch that that is the issue? I didn"t see how you checked if it was a flood switch issue. My ge dishwasher gdf520pgd6bb has wet dishes at end of cycle. I actually bought another element thinking that was it but didnt know ohms had to be between 15 and 30 :/ thought it had to be close to 0. But it still wont heat. Someone said something about tco reset on bottom which i found but it never tripped.
@@TwoKeysStudio thanks. It was the flood switch! Weirdest fix ever but thank you! When i took it out it wasnt making a shaking noise and the new one did so i immediately thought thats the issue and it was!
Somewhere on the interweb I read ion that this switch is part of the timing circuit for the heater. I did a resistance check on the element and it was good, so I tried the flood switch.
Not so much a timing circuit as a Thermistor circuit.. hidden in the flood switch assembly. GE should call it a float switch / thermistor assembly but they're keeping it a secret, even appliance repairmen seem in the dark according to numerous other websites and commenters. With a wet-vac and a 1/4 inch driver it can be replaced from the top.
Drain pump, not being level, bad hose or connection. Running it step by step through the test modes might help you isolate the problem. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I9TofsfqKDc.html
This video, however informative, left out one small detail. What was actually wrong with it? All it says is we are going to go from this to this... sure you changed out the flood switch but what were the symptoms that caused you to change the switch? What is the primary function of the switch. If I knew all of these things already I might not need to watch this video. My washer fills and drains fine, but my circulation pump won’t kick on. I think we are experiencing the same thing, are we not? If so I am definitely going to try this.👍🏼
Without this plug switch nothing will work properly in the dishwasher after I replaced my flood switch it fixed drain pump stuck on water not filling wash cycle cutting off seems this part regulates everything
My dishwasher is about 9 years old. Three years ago (2017) it wouldn't drain properly. Went to the GE site and in 90% of the cases, I was told the problem was the flood switch. I replaced the switch and it worked like a charm. Yesterday, on Thanksgiving day (of course) my wife reported the dishwasher won't heat like it should. Based on this video and others, I will be replacing the flood switch again. I think the frequent replacement might have to do with cleaning the filter. I clean it when I remember which is about every 6-12 months. The manual says to clean it every 3 months which I'm going to try to adhere to going forward. I do agree that the flood switch really is the "brain" of this dishwasher and quick, cheap fix. Matter of fact, I'm not even going to pull the dishwasher out to check element continuity. I'm willing to gamble on the $20 switch and if that doesn't fix it then I'll pull the box out. I just don't want to risk pulling something loose and then having a bigger leak issue. Thanks for the tips!
