Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

When dishwasher is started the initial drain cycle comes on. It drains any remaining water in tub, but then drain pump just stays on and never moves into fill cycle.

I read your solution to another Bosch model. I removed the inlet valve to vacuum out any water from the underpan from a "flood" problem. The pan was bone dry. I also had checked and cleaned the drain and impellers to be sure they were clear. I also tried to cancel the cyle buttons and restart.

None of these actions solved anything. I am going to test the inlet valve solenoid and check the intake filter today. I saw that checking for a stuck float may also be a problem, but I am not sure where it is. When I look back behind the inlet valve with a flashlight, I can see a small styrofoam looking donut, but it is sitting flat on the bottom.

    I read on appliancepartpros.com blog how someone took off their side panel; the two torx screws inside front rubber door seal. I was then able to get to everything below. The drain pan was dry, but I jigged the red float bar to the float switch a few times and it cycled out into the water fill cycle.



    The dishwasher is starting to run. I'll observe the cycle and see if all goes well.

OK Bosch Dw fans.........here is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred bucks.......so listen up. There is a tendency for the very small float switch to STICK in the ON position, which will cause the drain motor to continuously run......and DISallow any other function to work. DISCONNECT POWER. Did I mention to disconnect power? Take off the front base cover....2 torx screws. Remove the other 2 torx screws in the metal clips that fasten the top of the DW to the underside of your countertop. NOW...carefull slide your DW out. You may have to disconnect your water and elec supply if you do not have enough slack to pull it out. Once the DW is out of the cabinet, remove the shiny metal cover on the LEFT side by removing a single torx screw. You will now see a small plastic assembly with a red plastic piece that moves up and down as it rides on a small red styrofoam float. This up and down movement engages a small white plastic switch visible with 3 wires coming out of it. You can carefully UNSNAP this switch out of its mount, and pull the 3 wire plug off of it. THere is a small square blue plastic tab that is supposed to easily slide in and out of the switch. If it is stuck IN, you can sometimes tap the switch and the blue tab will pop out, which is what it is supposed to do without tapping it. You can carefully with a knife blade separate the case on this switch and note the way it comes apart. Clean out any micro debris out of the small channels that the blue tab ride up and down in. Then set it in the channel while holding up the small switch tab that rides on it and see if it slides up and down without sticking! I like to take a piece of wax paper and rub in on the channel and blue tap to provide some lube for the switch to slide easily on. Now, put the switch back on and manually move the red plastic assembly up and down while you are watching the blue tab. The tab should ride up and down with the red assy. If not, buy a new switch. Google the # on the switch and order one. If the tab slides up and down, put things together in reverse order and give it a try. Hope it works for you. This should take you an hour give or take. Take the $200 you just saved and have a night out on me. ........so even though these German Appliances have a good name because of past reliability, the american tendency to value engineer them with plastic parts to reduce costs and increase profit.........just cost you an hour of your time. Will we ever learn.? ......if it ain't broke, value engineer it until it only lasts through the warranty period so you can then collect service and parts blood money from your fellow american.

    This article was helpful. In my case, there was water in the flood pan and the float was activating the pump switch. I then discovered that the water inlet valve was leaking into the pan, so the flood pan and float were doing what they were designed to do. Now I'll just have to replace the inlet valve to stop the leak.

    I checked the switch, and operating fine, and not stuck in flood position. I also checked voltage across the solenoid in the operating position, and it's still not getting any current (no voltage read across solenoid) to energize and open. Any ideas?

Way to go!

The plastic lever / switch assembly may have got hung up. Or the flood switch (the microswitch activated by the styrofoam float) may be the problem. If this happens again, I recommend replacing both, because it's a lot of labor to do one, and not much more to do the other.

Let's hope that doesn't happen!

Please try this at your own risk of course!

I had exactly the same problem. The DW just wouldn't stop draining. I read the description above, about the plastic parts.

BUT before opening anything, I pulled the DW out a little and then shook it up and down.. not too much, but enough to get the valve system unstuck!

Lo behold - the DW is now running like before. Again, please try at your own risk.

Is it normal for 2 inches of water to remain in space where filter container is positioned...whenever filter is removed water is in the compartment where filter rests


In my experience the lowest section of the washer has always retained some water about a cup or two. If the one way valve(check valve) in the drain hose has failed or residue trapped in it more water will drain back at the end of cycle. You can see from the image the volume of additional water that would be trapped in the hose that if the one way valve leaks; the water in the hose would leak back into the tub.

the drain hose is required to go above the drain connection to prevent back flow into the washer. the one way valve in the drain hose is required to prevent back flow into the tub in the event of a blocked drain.

I hope that this helps.

Check Valve Replacement part 8268375 Whirlpool Dishwasher Repair

In some washers the check valve is critical because the pump reverses during the normal cycle. The attached video is an example of the check valve replacement in a Whirlpool. I have found all washers are similar.

You can usually hear when the pump has emptied the tub by a change of pitch from the motor. If you quickly open the door and observe the remaining water level that is as low as I would expect.

Hello,
After you the drain to discharge the remain water and the tub is visibly dry of water,then you open and load it do you see standing water after you have drained and know it was gone??
If that is the case what i believe your trouble is that where the dishwasher drain connects to disposer under the sink the drain hose is only leading from that nozzle downward,if that is so what is happening is the dishwasher is draining ok but backfilling whenever water runs through the sink. To fix that use a string on plastic zip tie and attach a portio of the drain hose so at one point the drain hose under the sink is higher that the nozzle and water in the sink will longer run into the hose and run upward since water is only going to drain down and wont ever rise on its own.The drain pump is powerful enough to push the drain water up that "HIGHLOOP" very easily.

Good luck i hope this has helped you to fix your dishwasher,
Gene

your better off just replacing the pump. you probably have broken glass or something else stuck inside the pump. to get to it you're going to have to remove the kick panel from the bottom of the machine. just follow the drain hose and you will see the pump.

Some wash water may have gotten into the bottom pan area below the wash tub. If water has overflowed from the tub into the bottom pan, the drain pump will activate and remain active until water has been removed from the bottom pan. To check for this, the lower front panels will need to be removed. With power turned off at the breaker, a wet-vac can be used to remove water from the bottom pan. If there was water there, check the door seals, door closure and make sure the drain hose has a high-drain loop. If the drain is shared with the kitchen sink, it may simply have backed up into the dishwasher through the drain hose when a full sink was emptied. The best drain system is for the dishwasher to have its own separate drain.

Dishwasher stopped draining after cycle


Some water always remains in the bottom of the DW (al least with most DW) but here is some help....

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...

Following a cycle, a small pool of clean water inside the tub is typical. Excessive water means the pump isn't pumping water out properly, the drain hose isn't carrying it to the drain pipe, or the house's drain lines are backed up. If dirty water spews from the air gap, the drain line is kinked or clogged. Note: If you've recently installed a garbage disposer, be sure the knockout plug for the dishwasher was removed when the connection was made (see your disposer instructions).

GE Nautilus won't drain after Rinse Cycle


Check disposer plug. If a garbage disposer has been recently installed, it is possible the disposer drain plug was not removed. The drain plug is a plastic piece in the disposer that blocks the hole where the dishwasher hose connects. Also check the hose connected to the disposal. Mine apparently had a kink in it. When I straightened the hose the dishwasher drained at full speed (I recently had a plumber re-route a hot waterline. He must has bent the hose). Hope this helps. If not go to the GE website. That's where I found my answer.
