Removing the filter module

A mounting bolt fell out and went into the drain where the filter module and motor are. I can see it but I cannot get to it. I am concerned the bolt will clog the drain eventually. I cannot figure out how to get the filter module/motor out so I can remove the bolt. I have removed the nozze cap, washer, lower spray arm and the top of the filture moduel but that is as far as I have been able to go. Any thoughts? I don't want to pay over a $100 for service when the dishwasher is not broken! Appreciate the help.

Re: removing the filter module

I suggest you take a look at the technician repair sheet that should be stored inside the front panel at the bottom of the door. Remove that panel under the door with screw driver. Inside, attached to the panel, you should find a troubleshooting guide and solution for technician. But it is easy to follow. Look for the section that talks about removing/replacing components in question.

Good Luck

My bosch dishwasher will not drain and makes a humming noise

Humming noise is an indication of your drain motor getting power but not spinning. Either your drain pump is defective and needs to be replaced, or something is stuck in the pump preventing it from draining out the water. Either way you will have to take the dishwasher out and get at the pump from the bottom of the machine.

U3 error code

Error code U3 could mean the drain pump could be blocked.

Remove the trays and the impeller arm. Empty the water with small container or towel. Open the filter plate and drain filter. Get the motor out and check the cavity for any rubbish. Also use a stiff thin wire to clean the passage between drain filter and motor cavity. The instructions for removing the filter plate and motor assembly are in the user guide.
Good luck

Really bad sound, pump dry or something

if some shuttered/debris **** inside of the pump it stuck on your impeller balde inside pump,its not easy to open pump assembly,
To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.have a nice day rate my solution if your satisfied,thanks

Rinse and dry

You probably don't have enough pressure from the pump. That's most likely caused by a clogged filter. So start by checking the filters- the easy one to get to is located behind the chopper in the base of the dishwasher. Grab the whiteish tube going from the bottom of the dishwasher towards the back of the dishwasher and get it to spin about 1/8th turn clockwise and then pull up. If that part works out for you, you'll see four torx screws. Don't loose any of these, they cost $6 each. Take out all four and pull the round white thing up and set it aside. You'll see gray plastic now. Towards the front, down inside, you'll find two more torx screws that are smaller than the first four. Take those out and get the two gray pieces they hold down out of your way. The flat one will come out easily, the other one will take some persistence. Once you get that out, you can see the smaller filter behind the chopper. It sits inside a thin groove, pay attention to this groove, as you'll want to put it back in the wrong place if you don't look it over before you take it out. Remove the filter and chopper assembly and clean it off if it's a mess. Then put the thing back together the same way you took it apart.

If this fixes your dishwasher, then you know pressure was your problem. If the problem reappears and you follow these steps again only to find the filter full of food again, then your chopper isn't chopping anymore. This is probably because the end of your impeller is broken off and isn't engaging the chopper anymore. If that's the case, replace the impeller (about $20 new).

To replace the impeller:

SHUT OFF THE ELECTRICITY to the dishwasher and unhook the wires in the electrical connection box. Notice that (hopefully) the white wire connects to a white wire and the black wire connects to the black wire and the green or bare wire wraps around a screw. You'll need to reconnect this back properly when you're finished with everything else.

Disconnect the drain line, either at your garbage disposal or at the dishwasher if you can get to that connection. Watch out for water, it'll go everywhere when you pull this loose.

Turn off the source of water, if you don't have a valve under your sink for this (you'll wish you did) then you'll need to shut off the water to your house. Disconnect the water supply line from the dishwasher, this connection is underneath the dishwasher opposite the electrical connection box.

Pull the dishwasher out and flip it over 45 or 90 degrees, your choice.

Unscrew the capacitor from the motor assembly (it's the round looking thing with two wires mounted to the motor), but leave the wires connected to it. Put the nut back on the bolt so you don't loose it. This makes getting the thing out easier.

Find the drain pump, it has a plastic tube connected to it. There is one torx screw holding that in. Take the screw off, pull the tube and the white thing with wires out, leave its wires attached. Your model may not have wires here.

Pull the wire connector off the motor. Remember where it went. Pull the two wires off the thermistor, they should be Yellow (with a black stripe) and white. Make a note that these two wires go on the thermistor so you get them back in the right place. Pull the Blue and gray wires off the drain pump. Make a note that these go on the drain pump so you get them back in the right place.

Next, there are three tabs that you need to find and pull out. They are little L-shaped wedges that hold the round gray assembly to the dishwasher. They are located about 1/3rd of the way around the circle, so once you find one, the other two are pretty easy to locate. Do not loose these parts.

Once you get those pulled out, the entire gray assembly can come out.

Look behind the motor for a bolt. Get your socket set out and find a 3/8ths socket. Put that on an extension, and the extension on your ratchet. Slide the socket between the white plastic protector and the grey plastic (it's a tight fit) and take out the bolt. Do not loose the bolt. Leave it in the plastic so you'll remember to put the plastic back. Grab the motor and turn it about 1/8 to 1/4 turn (it will only turn one direction) and then pull it out of its housing.

From here you can access the second filter, the one that isn't so easy to get to. It's probably fine. And now you can see the impeller, it's white and black and attached to the end of the motor shaft.

To remove the impeller, stick a screwdriver into the back of the motor, being careful not to damage the windings. Hold the screwdriver with one hand, grab the impeller with the other hand and unscrew it from the motor shaft.

Install new impeller on the end of the motor shaft, make sure it's tight.

Reverse instructions to put it all back together. Make sure you get the thermistor and drain pump wires connected correctly. White/Yellow to thermistor (little round dodad) and blue/gray to the pump (big thing on the gray part that drains water from the tub.)

Don't forget to re-attach the drain and supply lines, turn on water and check for leaks. Fix leaks. You may need Teflon tape, depending on the type of supply connection you had to undo. If you use plex tubing and connectors, you don't need Teflon.

Do NOT turn back on the electricity until the dishwasher is completely wired back up, closed, secure, and don't forget the ground (bare or green) wire around that screw.

I'm not responsible if you follow these instructions and end up shocking or killing yourself or your dishwasher. This is what worked for me.

Need to remove wash module

You should be able to hold the spray arm and unscrew the center section to remove the entire assembly. Be aware of any washers or other parts that need to be re-installed when putting it back on.
