Need to reset overflow switch

Hi.

Error 4 is internal leakage (overflow).

when this happens often the dishwasher starts with the pump running continuously.

Switch off the power from main circuit breaker, drain the inside of the appliance and clean the drain filter in the bottom panel of the tub. If problem persists, check the drain hose at the back. Ensure that it is not kinked, and that height is as from installation manual.

If that does not work, then the machine is faulty. Repair is done removing the kickplate at the base of the appliance, checking for water leak in there. Disconnecting pump hose and removing debris, testing the overflow switch by running a cycle with its contacts jumped. The inlet valve must also be checked to ensure that it is not leaking.

Turn off power and remove water from inside the appliance. Usually that is enough to sort out the problem.

Regards.

Ok so your dishwasher won't do anything... it justs sits there and "Hums" you can't make it respond to any controls, and the ONLY way to Stop it. is to unplug the unit, replugging back in it simply "Hums" again and will do nothing.
Now this happens because, the STOP Button, is pressed and the "Door Opened", during the Wash Cycle. This should NOT be done. You shouldNEVER TURN IT OFF MID-CYCLE. you should instead, Simply, pull on the handle, to Open the door, the system will take care of everything, after, you close it,and pick up where it left off. The turning OFF, makes the machine "Think" that a New Cycle, is going to be done, before the old one is finished, and resets itself to do it all again. But it still has water, that's not meant to be there so it must dump it out.
Now, the FIX. Take the Dishwasher, out, and tip over on it's side, tip to about a 45' angle. Water will come out from underneath, this is from a small "Overflow" reservoir. this reservoir has an "Anti-Flood" switch. The removing of this water will "Reset" this Switch, and allow the dishwasher to work again.
So what happens, is this, when the STOP button is pressed Mid-Cycle, the machine must "Dump" whatever water is still in the machine, into the "Overflow Reservoir". This water then causes the Anti-flood switch to jam, and this stops the machine, until it is reset,by the above method.

Some GE dishwashers have rubber check valves that expand and block drain hose.

Hi andrew did you get this fixed as it sounds identical to my problem.

Fixed mine very easily... After checking and cleaning the filters by the tub's drain, I checked the air vent atop the sink -- it had a small bit of gunk trapped in the outlet. Cleaned it out, ran a "rinse & hold" cycle and it drained the tub beautifully!

Hi BB,
There are only 2 places the DW can get water from. One is the drain line and the other is the supply line. We need to eliminate one to diagnose the problem, OK?

The first picture is a drain hose gone wrong...


Inspect your drain hose. If it looks like the pic above, you gotta fix that. Even IF that's not the problem right now... it will be in the future (and MAY be contributing to the problem now). You'll need to loosen the clamp, remove the drain hose from its' fitting, pull as much slack as you can get from the DW and then make a "loop" in it before reconnecting it. Like this...


The DW drain loop should be as high as the highest part of the sink...

I know that you have done a lot of experimenting in an attempt to figure this out. Just make sure that the drain hose is installed properly to eliminate it as the cause of the flood issue.

After you've made sure about the drain hose, leave the DW alone overnight. If you see water in the tub the next morning, you definitely have a failed valve on your DW. Since it's new (less than a year?) the valve is under warranty and will be replaced at no charge.

Hope this helps. If it's out of warranty let me know and I'll do the part look up for you and provide detailed replacement instructions, OK?

There are many things could make a dishwasher not drain, here's a list of the most common reasons.

• a clog or air gap in the drain line, often the problem is where the drain line attaches to the household drain line, if you remove this line you can clear any debris from the hose or hose connection.
• a defective pump, your dishwasher pump ejects the water.
• many dishwashers use a drain valve or solenoid, the solenoid can sometimes become stuck or defective solenoid.
• a defective motor, if the motor is'nt turinig or working the dishwasher won't drain.

I also had the oF error message just today, tilted the dishwasher back 45degrees and message dissappeared and all sweet as now. Put old towel under legs to catch overflow Thanks to david

similar problems here, repair man says its fine but the salt light was on so i added salt and works ok now. Some dishwashers don't function properly without the salt and rinse aid, even though you're pills may have then included, you still have to add them seperately, dumb but necessary at times.

the tech that came out may have pinched the drain hose when he put the dishwasher back in place. disconect drain hose from under sink. put dishwasher in cancel/drain mode see if water is coming out at a trickle if so, hose is probably pinched behind dishwasher
