Typical of the Bosch help desk, the instructions given to us related to the previous years model where access was via the filter etc.

Managed to find, on a different website (sorry), a similar problem from 2005 in which you had to access the pump via the plate at the underneath the dishwasher.

Cause of all the problems - a sinle piece of popcorn that had not popped!!

The water does not drain


Hello,

Follow the below diagnosis:

1. Drain Hose

It is quite common for a dishwasher to not drain because either the drain hose or the air gap (if the unit has one) is clogged up. Drain hose clogs commonly occur where the hose is attached to the main household drain line, or where the hose connects with the garbage disposer. Try removing the drain hose to unclog any debris. Don't forget to reattach the hose before you start your dishwasher again.

Checking a drain hose

Note:
Disconnect the power source to your dishwasher before you conduct this or any other check. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.

Before you can check your dishwasher's drain hose for a blockage, you have to gain access to the hose. First remove the lower kickplate panel located below the door. This panel can be removed by removing a couple of screws that are located either above or below the panel. On some models, the dishwasher door has to be open to access and remove the screws, but then closed in order to remove the panel.

With the panel removed, locate the drain hose. It is connected to the pump located below the lower spray arm. The drain hose runs from the pump to the sink drain, or to the air gap on top of the sink. There is a second hose leading from the pump that is a recirculation hose. When you are checking the drain hose for a blockage, you should check the recirculation hose as well.

Place a shallow pan below the hose to catch any spills. Disconnect the drain hose form the pump by pinching the wire clamp with pliers and then sliding the clamp up the hose. Remove the hose from the pump assembly and wiggle the hose in various locations. This may help to loosen the blocked debris.

Try running water through the hose to loosen and unblock the debris. A garden hose at full pressure is efficient to use for this task. Now disconnect the recirculation hose and check it for blockage in the same manner.

Once you have successfully removed any and all blockages from either or both hoses, reconnect each hose to the dishwasher. Replace the clamps, and replace the lower panel. Reconnect the dishwasher's power supply and run the dishwasher to make sure it is running proplerly.

Place a shallow pan below the hose to catch any spills. Disconnect the drain hose form the pump by pinching the wire clamp with pliers and then sliding the clamp up the hose. Remove the hose from the pump.

Reconnect on end of a new hose to the dishwasher's pump assembly and the other end of the new hose to the sink drain.

Replace the clamps, and replace the lower panel. Reconnect the dishwasher's power supply and run the dishwasher to make sure it is functioning proplerly.


2. Pump Assembly

The pump assembly is comprised of a pump, wash impeller, and drain impeller. The pump ejects the water from the unit, the wash impeller pushes water through the spray arm, and the drain impeller directs the water towards the drain port. Examine your dishwasher's pump assembly. Clean out any debris that may be blocking it. Replace the pump assembly if any of its parts appear to be worn or defective.


3. Belt

It isn't very common, but sometimes a dishwasher's pump assembly is driven by a belt. If that belt becomes worn and defective, then it cannot properly run the pump that drains your dishwasher's tub. If your dishwasher uses a drive belt, examine it now. If it shows signs of wear, replace it.

Examining a dishwasher belt

Note:
Disconnect the power source to your dishwasher before you conduct this or any other part examination. Either unplug the unit from the wall outlet, remove the appropriate fuse from the fuse box, or flip the appropriate breaker in the circuit breaker panel.

Locate and gain access to your dishwasher's belt. It will be located behind the lower kickplate panel. The belt will be made of rubber and will be about twenty-five inches long. Some are clear in color, while others are black. The belt will be looped around a pulley at the base of the pump assembly and around a pulley at the base of the motor. The motor will likely be towards the right, with the pump assembly located closer to the middle.

You do not have to move the dishwasher away from the wall in order to access and/or replace its belt. You only need to remove the lower kickplate/access panel. There will be a few screws holding the lower access panel in place. Remove these screws to remove the panel. You may need to first open the door to remove the screws, but then close the door to remove the panel.

With the lower panel removed, the belt is fully exposed. Closely examine your dishwasher's belt. You are looking for signs of wear such as little cracks in the rubber and places where the belt may be stretched. If you find signs that your belt is worn, replace it.

Depending on how much your worn belt is stretched, removing it might not prove to be too difficult. Replacing it, on the other hand, may require some tight maneuvering. You might want to try this tip:

1. Place one end of the above the pump pulley, around the pump housing.
2. Place the other end of the belt around the motor pulley.
3. Carefully roll the belt down from the pump housing to the pump's pulley.


Good luck.

My dishwasher has been fine for five years. Suddenly, about six months ago, the glasses came out scummy and there seems to be a coating on the dishes as well. Is this calcium deposit? If so, why would it...


Hello; first thing I would check is the spray arms, to make sure the holes are clean. A lot of debris from food particles, broken dishware, etc, can build up and block the spray holes over five years.
The spray arms can usually be removed easily, with a screw or wing nut holding them in place. There are normally three or four spray arms, (Be careful NOT to drop the wingnut or screw into the tub, as it will ALWAYS land in the least accessible spot!)
Once the spray arms are out, you may see debris partially protruding from the holes; DON'T try to pull it out, which can distort the size and shape of the holes, and thereby effect the cleaning. Instead, push the debris back into the spray arms, and shake it out through the large opening in the center where it connects to the dishwasher. Rap the spray arm against a firm but padded object to loosen any stuck debris. Once the "rapping" doesn't produce a rattling noise inside the arm, it should be clean.
Hope this helps. Check your owners manual for helpful maintenance tips like this.
Good luck!

Water not draining


There are several components to check when your dishwasher refuses to drain water. You need to check your drain hose, your pump assembly, timer, motor and drain valve and/or solenoid.

Middle arm isn't washing, need to check for debris.


How to remove the access panels....
There are many different styles of dishwashers built today. One of these should point you in the correct area's to look for the screws that hold the access panels on the dishwasher. Remember, remove power first.
The most common configuration of the access panels used today...
dwaccess.jpg
This is the newer "over sized" door, looks like a one panel front, but there still is small access panels on the very bottom....
dwaccess2.jpg
Some Asko Dishwashers....
2 Torx # 20 screws hold the toe plate on. Once toe plate is off, 2 Torx screw hold the lower panel on and the 2 brackets the hold the toe plate on have a springy locking tab, press the tab away from the bracket and the brackets will pull straight out. The service panel has 4 or 6 Torx screws holding it on, 2 are pointing up in the corners.

Motor and pump assembly screw and impellor help....

One of the most common question that I get on a dishwasher repair is "how does that motor and pump impellor screw come out?"
Inside many dishwasher pump assemblies is a screw that goes through the upper impellor and screws directly into the motor shaft. Since the motor shaft and screw are made of metal...you guessed it...they can / will rust. The screw can rust and become very tight and difficult to remove!! These screws are normally a right ( regular ) hand thread, socket or nut driver can be used to remove the screw. One hard thing to do is to hold the impellor still so the screw can be removed, they often just turn together. The impellor may be jammed with a screwdriver to hold it still so the screw can be removed...sometimes the impellor can be help still by placing a rag on it and hold tight with your hand, the rag will help prevent a sharp edge on the impellor from cutting your fingers. The odd time that screw is too rusted into place, soaking a little rust buster or 3in1 oil on it over night may help loosen it. Sometimes trying to tighten the screw a little at first will help break it free. There are some tool that can be purchased to help hold the impellor stillso the screw can be removed, these are only for a few models and pump assembly styles.


Anymore questions ask.

I would like to remove the Accumulator assembly. looking for instructions on how to remove. I think something is jammed in the motor gears etc.


Thank you for the reply. This is a pretty simple procedure. Just follow these steps:

1. Remove the lower wash rack and lower spray arm.

2. Remove the upper wash rack and spray arm.

3. Locate the screws holding in the upper spray feed tube. Remove the screws to the feed tube and turn the whole assembly 1/4 turn to the right (CW direction). The entire assembly will unlock from the wash pump assembly and lift out.

4. Remove the strainer assembly (known as an accumulator) that covers the pump sump area by loosening the screws around the perimeter (you may need a torx type screwdriver for this, I believe the size is a T-2).

Once the accumulator is removed, inspect the sump area for food particles and debris. You may want to additionally remove the chopper assembly cover to make sure the impeller area of the wash pump is not clogged. If you need some guidance, searspartsdirect.com has some very helpful exploded view diagrams to assist you. The chopper assembly cover will be listed as item 8 under the "Pump and Motor" heading.

If you have any questions, or require additional assistance, please let me know. I hope this helps you.

Kitchen Aid Dishwasher seems to have gotten louder over the last month


time for a cleaning.. dont worry.. its pretty easy (but gross and probably full of broken glass)..

1) switch the breaker off at the panel
2) remove the baskets and unscrew the plastic thing holding on the bottom wash arm (remove the wash arm and check it for debris)
3) remove the top washer water feeder (there should be little clips that unclip it from the inside of the dishwasher).. and then it twists clockwise and pops out
4) you'll need a med flat head or better yet a star screwdriver set for the next part
5) unscrew the screw(s) holding down the plastic cover that covers the water pump intake inside the dishwasher.. this should expose a 'trap' at the front.. BE CAREFUL
6) start cleaning that out.. there should be everything from GLASS, to olive pits to cherry pits etc etc down there.. get it all!
7) while you're in there, there is another (delicate) cleaning task with the food grater/processor inside.. there is another screw that once removed, allows you to gain access to the food grinder.. there's probably debris in here as well.
8) once you've cleaned that out, take care to line up the grater into the right channel before you reinstall everything..
9) put everything back together, and run an empty load on hot with hot dry and it should be waayy quieter.. (and you'll be surprised at how clean the glassware is).

good luck

Lower spray arm will not spray water


I just had a simliar problem with all spray arms and solved the problem by cleaning the food screen. Basically, it takes water pressure to make the spray arms rotate. Before assuming there is a failed part, make sure the spray arms are getting max water pressure by checking the food screen. Here's how I serviced my Kenmore dishwasher.

The lower arm assembley is removable by twisting the center plastic piece. It's not very tight and should come off easily by twist with a pliers (but gently). Then remove the tubing to the upper arms (Two screws). Then remove the bottom drain cover (4 star screws).

Under the drain cover are two more things to remove. One, a plastic plate over the bottom of the water drain (1 screw). Two cover to the food screen (1 screw). After removng the screw to the cover of the food screen, it will be a little difficult to remove that cover. The side opposite the screw requires releasing a catch with a screw driver. It's hard tell which way it releases, just keep trying different ways until it pops up. The cover may stick a little beacuse of the food stuck in the screen.

Once you have access to the screen, the screen can be removed by pulling on the center shaft (spring loaded) with a needle nose pliers and lifting the screen straight up. (Note: there maybe a blade next to the screen used to braek up the food.)

After removing the screen, clean it (I used a plastic scrub brush).

Reassembly is performaing these steps in the reverse order.

Hope this helps!

Water will not drain away at end of wash programee


METHODS TO REMOVE COVERS ON EACH MODELS ARE DIFFERENT. BASICALLY, REMOVE THE LID FIRST THEN CHOOSE WHICH COVER(S) YOU WISH TO REMOVE. FOLLOW THE PERRIMETER OF THE COVER AND REMOVE ALL THE SCREWS SECURING IT. ONCE SCREWS ARE REMOVED, SLIDE COVER OFF AND INSPECT FAULTY COMPONENT.IF YOU CANT SEEM TO GAIN ACCESS TO THE DESIRED AREA, I SUGGEST A TECH. BECAUSE THE BASE WOULD HAVE TO BE SEPERATED FROM THE BODY CAUSING CAUSING FLOAT SWITCHES ETC TO FALL OUT. NOT FUN IF NEW TO IT.
