SOURCE: Bosch dishwasher cleans but will not drain.

Remove the drain hose where it attaches to the disposal. This area often clogs and will prevent any d/w from draining.

SOURCE: Loud humming noise when dishwasher is filling up with water

your model is pretty new. just so you know your warrenty is 1 year parts and labor. 2 years on parts. it should not cost that much money.

there are two components that start before the circulation pump.(wash noise you hear)

first sounds you hear will be the drain pump. usually rattling noises if something is in it but it can make a hum noise if something is jamming the drain propeller up. which is accessible with a T20 torx driver. take the filters out and the mesh filter. and unscrew the screw in the base towards the left. pull out whatever is lodged.

the other humming sound can come from the next component that activates is the watervalve. make sure you dont have a kinked water intake line. otherwise its a bad valve. i have had to change a few of those water valves out already but not for a hum noise on your model. you have a new style water valve. when brands make new parts we get problems fast sometimes..

SOURCE: Drain was clogged and the dishwasher overflowed.

Probably the aquastop (if you have one). We have a similar problem after our owerflow. The dishwasher is starting and running through the programs but no water is coming.

SOURCE: My Bosch shx46A05UC no longer will drain.....it

I ran into the SAME problem with my Bosch SHX46A06UC /21. The problem ultimately ended up being a clog in the air gap vent, (meaning, SOMEBODY ran the dishwasher without the bottom filter being in place or not in place properly). Remove the air gap cover and upper surface nut to drop the air gap vent into the area under the sink. Disconnect the hoses from the air gap vent filter (placing a bucket under the hose from the dishwasher). Run the drain cycle on the dishwasher. The washer should drain into the bucket and let you know that your pump works and that there are no clogs or kinks in the drain hose. (This will also remove the clog if so). The air gap vent's smaller hose connection is MOST LIKELY where your clog is. Look at the upper end of the air gap vent. You'll see a couple of clips on opposite sides of each other, that hold the air vent cap in place. Using a small screwdriver, (or your hands if you can), depress the clips (or one at a time) to get to the point where you can pull the vent cap off the filter. Either use water or a thin, long blade screwdriver to force any objects out of the filter. You should now have full flow through both branches of the filter. Using water and a rag, clean the vent cap and filter. Mount the air gap vent filter back onto the sink. Reconnect the hoses and remove the dishwasher's internal filter(s) and clean them as well while you're at it, making sure to remove any debris that might remain underneath the filter and has the chance of clogging the unit again.

Run the washer again to test. You should be good!

Cheers!

SOURCE: Dishwasher stuck on wash cycle

Hello,

Based on your description I'd say the issue is with the control. Bosch has had a history of this exact problem I'm about to lay out for you and this is the first thing I'd be looking for if called out to service the unit with the symptoms you've described. Heck if you called me with this description I'd be happy to bring you a new control and have a first time complete. ( unless you requested a re-solder option...see below re: my opinion on this )

I digress,

As I've alluded to the issue is within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).

My first suggestion would be calling in an authorized bosch servicer if that is an option for you and your budget however, If you cannot afford that option or feel capable of checking this on your own, there`s a way to visually inspect the control yourself. It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit sit`s and takes forever to finish and eventually display's the "1" error ( on models with a display ) because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed.

**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.**

Hope this answer`s your question, let me know if I can assist you further.

Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness.

Good luck.

Wash cycle stopped with water in the bottom. Seems like there is no power. Can't get lights on cycles buttons to turn on. Power button does nothing. Checked circuit breakers. All are on. Lights and outlets...


Check the wiring in the units junction box. Its located at the bottom right corner. You will likely find melted connectors. If so, you need to cut the wires back and replace these connectors. Make sure you turn the power off before doing any of this work of course. Good Luck.

My dishwasher is just three years old. The other night my wife said it made a loud noise while it was running and now it is full of water at the end of the cycle. Any ideas?


The pump attached to the end of the motor shaft inside the tub may have broken. If it doesn't spin the water wont pump out but usually the water wont spray on the dishes either. Watch it run a second with the door open and the door switch make to see if it's spraying.

When washer is started make loud grinding noise


Very likely the bearings in the motor have begun to fail. You can replace the motor, but for a 15 year old DW, sometimes it makes better sense to just buy a new one. Depends on the features the old DW has, vs new, vs motor replacement cost.

Reply back and we can you more.

Bosch Dishwasher SHX46A05UC/23 - No Water


Sounds like your recirculating pump is clogged If it is water can't get up enough pressure to turn the sprayers.
You'll need to start pulling parts out of the bottom inside to get to that pump. I don't work on a lot of Bosch, but that sure sounds like it to me. I see this a lot. Hope this helps...

Bosch SHX46A05UC/30 runs for 4 hours.


The circut board in the biege plastic case under the buttons on the right has what is called a cold solder. In other words the solder melts under operational use. Some are repairable and some are not.

1. UNPLUG DISHWASHER or turn off breaker and test for electricity.
2. Remove screws from door panel.
3. Take pic of position of wires going into plastic box.
4. Remove top section of plastic box with buttons exposing small circut board.
5. Open plastic box exposing large circut board and in the middle of it you will see a black spot where the solder has popped. Resolder and reassemble OR replace old circut board and then reassemble.

A new circut board is about $135
Usually electrical parts are not returnable

Dishwasher making loud noise


Newer washers are designed with a food grinder inside to help grind up large pieces of food. What you are hearing is the grinder doing its job. You do not need to worry about the noise. It should go away after a while as the food particle is ground up.

Loud grinding noise when washer is draining


something in the impeller housing. not usually serviceable. not sure if that unit has two pumps. you could look underneath the tub and try to determine that, and where the noise is coming from.
i am confident the issue relates to a pump unit.
good luck
