Overflows to the right-hand side of sink where that thingee is (white cylinder looking thing where water comes out). I am wondering if there if a food filter in the bottom of dishwasher that needs to be emptied or something and that is what is make it back up all the way to top of sink (it should be flow up toward that thingee but taking a left and draining down the garbage disposal...right???

    Yes the drain from DW is connected to disposal but we always run disposal before starting DW. DW drain is connected to disposal drain with a "T" shaped connecter and it looks like it is supposed to drain into disposal...and it is an uphill climb...however there seems to be extra pressure and it paases opening to disposal drain and shhot straight out the overflow openming

    Is the drain from the dishwasher connected to the garbage disposer? And does the disposer work correctly? (You might try running it for a moment to make sure it isn't stopped up.) Is the water backing up in the same bowl where the dishwasher is connected, or in the other one? Also, does the sink drain properly, or is it very slow to drain?

It sounds like you have an Air Gap...a separate device that is used to prevent back flow into the DW. Take off the top of the air gap and see if it is gunked up and or clean it with a shop vac...as well disconnect the line to the drain evac it as well... also there is a reservoir in the back that is attached to the drain pump...take the screws out...see that it is clean and free of debris...be careful as glass or other particles can be in there. Also have you had a new dispoal installed if so the drain plug may not have been removed. As i read more I am certain you have an air gap...make sure it is cleaned and free from obstruction....if this does not solve the problem...here are some other GE specifc things and a link to help......


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Here is some GE specific info and a link.....

GE dishwashers will have a sump entrance screen ( #4 ) that should be removed and checked for any gookus, see 1 or 2 screws on the cover top, which is behind the lower spray arm. Almost all ( some newer GE dishwashers have a separate drain pump and motor - but for our purpose, we will talk about the most common GE dishwashers ) GE dishwashers have a drain solenoid ( #1 ) that can fail and stop the draining. If the solenoid cannot pull in the silver plunger, the drain port will not open to allow the motor and pump assembly to drain the water out. The solenoid can be ohmed with an ohm meter for continuity, or tested to see if it is receiving 110-120 volts AC. Many GE dishwashers have a self clean filter ( #3 ) inside at the back. The draining water must pass through a plunger in the self clean filter body. This can get clogged up, or the plunger may twist and distort and not allow the draining water to get past. The filter can be removed from the inside and the plunger will twist out of the self cleaning body for testing/checking. Next obstacle for the draining water in the back flush valve ( #2 ). This valve can twist or distort and block the water flow as well. The drain port will need to be accessed to check this flapper valve, the drain port will untwist from the self clean filter body. All hoses in-between the items mentioned above and the drain hose itself all the way to the house plumbing should be checked for restrictions.

Some extra filter, draining tips and pictures....

During the wash and rinse modes of the cycle, soiled water falls down the back of the tub and into the filter area. The water comes through the filter and back into the tub. During the wash and rinse periods all ( we hope! ) the water will pass through the filter. The soil will settle into the collection chamber and is held there. When the dishwasher goes into the pump out mode the water in the sump is pumped through the collection chamber. This closes the piston valve to the inside of the tub. The pump flushes the collection chamber of all the food soil and pumps it down the drain. A check valve is located in the drain line port. This valve allows the water to flow in the drain direction only and prevents the water from coming back into the tub. The drain line check valve must close in the back flow direction or the piston valve in the collection chamber may not reopen into the tub after the pump out is complete. Water should "fall" through the filter and go back into the tub....the heavier food particles go down into the chamber and are collected.

Here is a link for you to check out...I have all this info in my data base but since it is in PDF format it does not translate well to this format...

I hope this helps...it is always useful to include the Model #...more specific instructions can then be provided

Good Luck and good day.....please rate my effort...the Fang

Dishwasher filling up with water


A lot depends on how the drain hose is connected to your sink. I have included a typical connection diagram. It's for a Maytag, but the installation can be for any brand. If yours uses an air gap then I suspect it is defective. Any other connection method would indicate a slow drain.

Electrolux dishwasher overflows


Two things to consider....clean water or dirty water?

Clean water usually indicates the fill valve is not shutting off all the way and the fill valve is "weeping" water in all the time = new fill valve time!!

Dirty water usually is not a dishwasher problem but more of a plumbing issue. Often the sink drain that carries the sinks water outside is not fast enough and some of this sink water is backing up into the drain hose and filling up the dishwasher through the drain hose. The drain from the sink to outside needs attention as this type of a problem indicates a slow house drain for that sink.

The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwasher.

Bosch dishwasher overflows thru front door


Is there an opening on the right hand side of the inside of the machine?I had this happen and it turned out it was because this hole (opening) needs to be clear during operation. Try running it with nothing on the right hand side and if it doesn't overflow, that's the problem. You can only put short stuff in the back bottom rack on that side.

Overflow draining to the sink


it's supposed to drain out the same drain pipe your sink uses. If it is overflowing into your sink, then your drain pipe is clogged. Your sink probably overflows when your disposal runs too, right? Unclog your pipe and you're good to go.

Blanco dishwasher overflows at end of cycle


There is a float connected to a switch that controls water level. It is usually round and will move freely up and down by hand. But your problem might be a levelling related one. The dishwasher must be level to operate correctly. Use a torpedo level in the tank base to check front to back level and side to side level. Adjust the front legs to level the unit.

Dishwasher does not drain, instead drains through overflow valve in sink. No apparent clog seen.


Usually the sink connection is not an overflow, it is the main drain from the dishwasher. It is more likely your s-bend is blocked under the sink- try putting a bucket under it and unscrewing the u-shaped piece and cleaning out (remember don't wash it in that sink while the pipe is off)

Simple solution. DO NOT spend the money on a tech coming to the house.
This error code comes from getting too much water in your machine, either from a dish filled with water emptying, or perhaps a clog from the sink that prevents your machine from draining. It is meant to prevent overflows from too much water being in the tub. It is a simple fix though!
First of all you should at least shut the power off on your machine. For the effort of a couple of more steps, it wouldn't hurt to shut the breaker off at the fuse panel. You will have to unscrew the undercounter tabs that mount the dishwasher to the countertop. They are located just under the counter sticking out from the top of the dishwasher when the door is open. Then proceed to pull out the dishwasher from under the counter. You will only have to pull it out about half way and you will find the overflow valve. It is located on the right side of the dishwasher just under the insulation and level with the lower hinge on the door. (Right side when you are looking at the machine.)
There are two overflow valves. One looks like a small cup, the other looks like a cylinder with a float in it like your toilet. Both of them have black rubber covers near the bottom. Take these covers off and about a quarter cup of water will flow out of these overflow basins. Allow them to completely empty, then replace the rubber drain covers and then replace the unit under the counter.
Once you turn the power on, the error code should be cleared and you are ready to use the dishwasher again.
