Our dishwasher was getting little or no water flowing during washing. We removed the filter assembly (part 451) to clean it and found it was full of crud. We cleaned out most of the crud and tried to remove the remaining crud around the flood switch (308), then ran it again this morning. I listened and thought i heard some water running, but when i opened it after the cycle finished, it was still dry, and most or all of the dishwasher liquid residue left from the previous failure to clean was still here. I tried turning the flood switch, and was able to twist is up to about 90 degrees, but it did not come out. Is this likely to be a flood switch problem, and if i need to replace it, how can i get it out? -- thanks, jeff hecht
For model number GDF540HGD1WW
Hello Jeff, Thank you for your inquiry. The two parts we would recommend checking to solve this issue are the flood switch and water inlet valve. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. To remove the flood switch, You will have to remove the lower rack, remove the lower wash arm, remove the lower coarse filter, removed fine filter, and you may have to remove the filter adaptor as well. Removed two 1/4" head screws with nut driver to then remove float switch, unplugged float switch, plugged in new switch, and reverse the process. Hope this helps!

Unit tries to fill but no water is being drawn from water line. Need to know if you think it is the flood switch. Prior to this, during heated dry there was bad odor coming from steam escape vent at front of washer. Heat coil are covered with what i believe is lime. Would any of this have caused the unit to not draw water? Also, do i have to remove the unit to work on the flood switch or can it be done in place/
For model number GDT625PSJ2SS
Hi Paula, Thank you for your question. It sounds like you may need to take a look at your water inlet valve. That would be my first go to for what would not be bringing water into your appliance. You should be able to test that valve with a multi meter. Yes you would have to remove the unit to get to the valve and check the flood switch as well. I hope that helps. Good luck with your repair.

My dishwasher is not draining and i have checked the drain pipe on both ends and there is no clogging and when it goes into the drain phase i hear what sounds like the pump trying to work but no water is being removed from the inside.
For model number GDT580SGF4BB
Hi Michelle, Thank you for your inquiry. There are some parts that you will need to check to see which one is causing the issue. You will need to check the drain pump, the drain hose and the float switch. I hope this helps. Thank you and have a great day!

My dishwasher is only 2 years old but doesn't dry the dishes now, they used to come out scolding hot when it was done. Now they are drenched and sometimes smell from sitting wet too long. I tested the element and it tested good, but i still went ahead and replaced it to make sure it wasn't the problem. It still doesn't dry the dishes. I was told by a friend that it may be the high limit thermostat. I remember seeing something like that in connection with the element underneath but i can't find the part number anywhere to replace it. Any other ideas on how to get the part number or other ideas of what it could be?? thank you
For model number GDT580SMF8ES
Hello Chaz, thank you for your question. This unit doesn't have a thermostat or fuse on it that would relate to the heating cycle. If the heating element was replaced and did not fix the issue, we would recommend replacing the electronic control board part number PS11721498. I hope this helps!

Hello there, yesterday I started the cycle on the dishwasher came back into kitchen about 1/2 hour later and there was water all over the floor. When opening the door water came flooding out the front door on both sides, pulled the dishwasher out, checked pipe no blockage, had pipe in sink started rinse cycle, water had no problem going up pipe and into sink. I thought the problem was solved, bu I started the wash cycle, about 15 - 20 minutes in the cycle, the water once again started coming out but this time it seemed like it was coming out just under and behind the door. Help, I am going through a lot of towels. LOL! Thank you for any help. Sincerely, Janette
For model number GDF510PGJ2WW
Hi Janette, Thank you for your question. If the dishwasher is leaking, there are some parts that you will need to check to see which one is causing the issue. You will need to check the gasket, the gasket tub plastic, the water valve assembly, the door vent seal, the hose loop drain, the diverter assembly and the drain pump. I hope this helps. Thank you and have a great day!

April 25, 2019
Hey all! Trying to avoid getting soaked with a repair bill on my GE profile dishwasher, hoping to get a bit of insight or confirmation that the flood switch is the most likely problem. We've had the dishwasher for about 4 years, did not really do much maintenance at all until recently when the dishes starting coming out wet. Cleaned out the filter at the bottom of the unit, which was quite loaded up with residue, but would still pass water "pretty well". Neither the type of cycle selected, "power dry" setting, nor the temp of the input water (by running sink until hot) has any noticeable effect.Thanks for your help! todd
For model number PDT750SSF2SS
Hi Todd, thank you for your question. The flood switch can sometimes cause this issue, however most of the time the first part to check is actually the heating element for your appliance. That part tends to be the issue more times than not. You can test that part with a multi meter. The element should be reading between 0 - 50 ohms of resistance to be in working condition. I hope that helps. Good luck with your repair.

Will not drain. I replaced the drain pump wd35x20878, but still won't drain completely. Sound like pump kicks on and off. Some water does enter the garbage disposal.
For model number GDT580smf4es
Hello David, thank you for your question. We would recommend testing the float switch and turbidity sensor, Part Number: PS11762980 and PartSelect Number: PS8690623. If these parts are in working condition, the issue would be with the electronic control board as you've already replaced the drain pump. I hope this helps!

Under the dishwasher there is a wire harness with a little plug-in connector on it. Somehow the wires were all wrapped together and the connector piece is off. Do you have that part and what would it be called? It goes to the flood switch.
For model number GDF520PGD4BB
Hello Rebecca, Thanks for your question. The connector for your model is part number PS8756335, it is known as the DC Harness Assembly. I hope this helps.

No water flowing into dishwasher
We tried cleaning out the filter and it clogged with a huge amount of gunk. We removed the gunk, scrubbed the filter, and tried running the dishwasher, but still no water. That took over an hour (not counting the time the dishwasher spent running). Then we tried your diagnosis center and it pointed to the flood switch or the water valve. I extracted the flood switch (another 30-60 minutes) to check it, and it also contained gunk and (significantly) did not rattle, which made me suspect the flood switch was the problem, so I ordered one. Once the replacement arrived, I checked it and the flood switch rattled, confirming that it should work properly. I spent 30-45 minutes installing it, plus the filter assembly and racks I had to remove to access it. Ran the dishwasher and everything came out sparkling clean. I don't know where the gunk came from, but if you aren't getting water and the filter is full of gunk, check the flood switch.

Dishwash would not fill with water.
1. Remove lower dishwasher rack.
2. Remove flat course filter screen in bottom of dishwasher by unscrewing the 2 hand screws at the rear of the screen. Remove the round fine filter (at the front of the course screen) by rotating counter-clockwise by hand.
3. Remove both the fine and course screens exposing the 4 inch tall, skinny, round float valve. DO NOT rotate the float switch--remove the float switch by pulling it straight up.
4. Remove the electrical plug on the bottom of the float switch.
5. Install new float switch taking care to remove the old O-ring and ensuring the new O-ring is properly located at the bottom of the new float switch.
6. Follow instructions in reverse to complete the reinstallation.

The GE Cafe series Dishwasher not drying dishes.
I pulled the dish washer out and, make sure you turn off the power, disconnect the water and drain line. un screw the mounting screws.
The first thing i checked was the drain filter which was clogged. I took shop vac and sucked all the excess water out and removed the flood switch. seemed ok but you can't tell if its ok, so just replace it. I then removed the door from the unit. I needed to replace the dispenser. After the door was off I tilted the machine forward, to check the heater. I pulled the quick connects off and checked the resistance across the heater, should be 16 ohms mine was 16.3 so heater not bad. looking at the bottom of the machine, follow the left hand wire and it will attach to a thermal overload. (a small round disc which is not listed in the parts manuals ), I checked for continuity across the switch it was open.
On this model GE the switch is resettable, a small reset button in the middle of the overload. I reset it and continuity was restored. only three things might cause this to kick. one the flood switch, the vent fan or the turbidity sensor. I replaced all three and the machine is working great.
If you have replaced your heater and still doesn't heat, try resetting that switch. and give GE a big thank you for not telling any one about the switch.
A big thank you to PartSelect for having all the correct replacement parts.

Heating Element Wasn't Turning On So Dishes Weren't Drying
Ran the diagnostic code test and no alarms turned on. Ran the heater test and it didn't turn on. I figured it was either the flood switch or the heating element itself. Removed and cleaned the flood switch and still nothing. Replaced the old flood switch and now it works like a charm. It took a minute to run tests and figure out a plan of action, but after ordering and receiving the part it was a quick operation to replace the old flood switch. Kill the power. Remove lower basket. Remove lower arm. Remove the coarse filter and the fine filter. Dry up water in bottom of dishwasher. Use 1/4" nut driver to remove two screws holding flood switch in place. Unplug old switch. Plug in new one. And put everything back. Saved a few bucks for sure. If I can do it, you can do it!

Pushed floid switch bsck into lace and attached white plastic retainer with two bolts and then set screen cover back. Very simple and easy.

Dishwasher would not receive water when started
The service lady looked up possible trouble items and narrowed it down to the flood switch. Being the most likely cause, I ordered a new one. I removed both trays, the lower sprayer, and both screens. The flood switch has an electric plug on the bottom of it that just pulls off. Just as with other appliance repairs, I actually got the old flood switch to work again before trying the new one. I should have tried to free up the float before ordering the new one. But in case this happens again, I’ll just put the new one in.

No heat in both water and air
Followed troubleshooting procedure to determine that defective Flood Switch caused the problem and not the Heating Element. Replaced only the Flood Switch. I also replaced a deteriorated door gasket.

De-installed dishwasher from cabinet, removed door, and tipped unit over with back of tub resting on floor.

I followed the document referenced here for the troubleshooting and repair procedures: GE Appliances Technical Service Guide, 2012 GE Dishwasher, 31-9226.pdf available on web.
