Question about Bosch 24 in. SHU43 Built-in Dishwasher

1 Answer

We're trying to install our dishwasher and there is a 3rd hose attached on the side. It appears to be a drain of some kind, part number, we think, printed on it is FRU 10967 19/07/04 08:33 Can you tell us what it is and where and how to attach. The one it's replacing only had the water hose and the drain hose, no third hose. Thanks

I just installed my Bosch dishwasher a few days ago and wondered about the same thing. The instructions for hooking up water supply and drain lines did not mention this third hose at all.
However, 'the third hose' (which appears open on the lower end, but loops up high) is attached at the other end at a point directly on the other side of the dryer wall from an opening inside the dishwasher, described elsewhere as a vent (somewhere in the manual we are advised not to place anything such that the vent could be blocked). I'm assuming that when water is pumped to the drain, since the chamber is otherwise sealed, there has to be an opening for it to breathe in air to replace the evacuated water, and conversely to allow air to leave when new water is taken in; thus both vacuum and pressure build-up are avoided.
So, although this third hose is not involved in installation, a little foresight by the manual writers would have had them mention it and put our minds at ease. Maybe we are not supposed to be curious....

Belt, Water Pump

Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

Drain Pump

If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.

Drain Impeller

The drain impeller is attached to the pump and pushes the water out of the dishwasher, through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.

Pump and Motor Assembly

If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might need to be replaced.

Clogged or Improperly Installed Garbage Disposer

If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.


Drain Hose

If the dishwasher won't drain the drain hose might be clogged. Remove the drain hose from both the dishwasher and the sink drain to clean it out. The most common place for an obstruction is at the garbage disposer.

Check Valve

If the dishwasher won't drain the check valve might be stuck closed. The check valve is a device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is located in or at the outlet of the pump that the drain hose attaches to. Sometimes the check valve is accessed from the inside of the unit depending on the model.

Check Ball

If the dishwasher won't drain the check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

Will not drain. I have checked the drain hose for blockages, nothing there. I pulled the drain hose from the pump and the dirty water flowed out.


Drain pump not working anymore. Depending on your make & model there are a few ways to acces the drain pump, but most common practice is removing the Top Panel (fastened by 2 screws at the back) and then the side panels. A normal Dishwasher should be attached to the sump.

Replace it and all should be fine, the reason why dirty water is coming out when you remove the hose is called a Siphoning effect. The dirty water is what your drain pump can not push out of the dishwasher.

Kind Regards :-)

Why is the water still on the bottom... will not go away? how do u do that?


Drain pump not working anymore. Check the outlet hose and let it lie on the floor to drain most water out of the dishwasher, then remove the Top Panel (fastened by 2 screws at the back) and then the side panels. A normal Dishwasher should be attached to the sump.

Dishwasher will not drain.


Hi,

The first thing I`d recommend is checking the drain for blockage. The most likely area for these unit`s to have an obstruction is where the drain attachment is located under the sink, downstairs, or whatever the case may be.
Remove the clamp fastening the hose in place and check for any debris clogging the drain. Keep in mind some install`s have had to join two pieces of drain hose together if it`s an extended run, check the ``coupling`` at this junction as well.
When you have the drain un-attached, grab a bucket and test the drain. Hit the two buttons for cancel on your dishwasher and see if the water drain`s freely when not hooked up to your household plumbing.

The other possible cause, and especially bosch, (I can tell you first hand from doing Bosch warranty for over 10yrs.) is a fallen drain loop. What that means is this. The dishwasher proper install calls for a ``hi-loop`` in the drain line. This is ``required`` to minimize the possibility of back flow, but also to take advantage of gravity to assist the drainage.

Sometimes these install`s are either done improper, not at all or just vibration`s cause them to ``fall`` if not secured sufficiently. You`ll need to confirm the drain hose has a ``Hi-loop`` in it somewhere between the outlet of the dishwasher and the connection to the household plumbing.
If it`s routed under your kitchen sink it should be an easy check and remedy. If it is looped great, look for a clogged drain. If it`s not looped but there is a lot of extra rain hose, you should set up a loop (refer to the installation guide for further info). If there appears to be very little extra hose before the household connection that could mean the ``hi loop`` is behind the dishwasher. You`ll need to confirm it does or doesn`t exist because it IS necessary for long term well being of the machine...which leads to the other possible problem.

If the loop was never put in place and the drain hose has been laying along the floor since it`s install the drain pump may have failed from functioning beyond it`s designed specs. The outlet/drain pump will need to be replaced, but not before correcting the drain install.

I have plenty of part`s info, installation guides and manual`s via pdf files. If needed I can send an email to you with any info you require, but I can`t attach them via these post`s.

Hope this has helped you with your problem. If so please take a second to rate the solution I provided for you here at fixya. If not please post a reply and I`ll try to assist you further.

Good luck.

I have a GE triclean dishwasher that leaks when it is filling. It is ok when washing and draining. The leak seems to come from a metal plate in the center bottom when I take off the kick plate


Here is the possible solution. The incoming water goes through the valve and then to the black hose going up on the left side of the dishwasher, the hose goes up then bends and it's end is just inserted on some kind of pocket. I think the end of the hose in your dishwasher just looseened and it spills water from this pocket. To fix it you need to pull the dishwasher just a little bit from under the countertop, (make sure to unsrew 2 screws up there) until you get access to the hose and then insert it deeper in the pocket. I would also attach the hose to the side of the dishwasher with the duct tape.

Installation


It sounds like you have connected your dishwasher to a garbage disposal.

  1. The 2 hoses provided with your dishwasher connect together.
  2. You run the drain hose through a hole in the bottom/back of your cabinet, then up to the top of the cabinet, then connect it to the drain on the garbage disposal. (The reason that you run your drain up to the top of the cabinet is: This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher.)
  3. Be sure to knock the plug out of the drain of the garbage disposal. A garbage disposal is designed to work with or without a dishwasher. The plug is in the center of the drain. The best way to knock this plug out is to pull the garbage disposal, and with a flat screwdriver, knock the plug out.
  4. Then remove the plug from the disposal. Reinstall the disposal.
  5. Install the drain hose. The drain hose will connect right up to the disposal using the clamp provided with the dishwasher.
This should help you. If not please attach more info.

Dishwasher will not drain


tichi, without a complete model number and using a model close to the one posted, there is a couple of things you want to check. It appears that you have a drain solenoid assy. that sits on the left side of the motor assy. If this selonoid overheats or fails, you will get a no drain situation. It is not hard to install a new one. I have found on these models that a defective timer will continue to send voltage to these selonoids and burn them up. Result, no drain. There is also a piston and nut assy. that sits under the filter screen in the back of the tub. You can get this from the inside. If this piston nut assy. does not seat as designed, you will have water in tub after the drain. From your post it sounds as if the drain selonoid is bad. I will attach a couple of pictures of these parts.

Dishwasher won't drain all the way


After cleaning the air gap thingy my machine works fine again. This thing sits on the left lower back side of the machine (left when you are standing in front of the machine). It is a transparent plastic box with 3 hoses attached (drain hose from pump, drain hose to the outside and water). Inside the box is a black plastic float. If debris gets caught in there the float gets stuck.
Solution is to remove the part by pulling the 2 drain hoses out (there is a small black clip holding them in) and unclamp and remove the water hose. Rinse and shake the housing until the float moves freely again and reassemble.
