Question about Bosch SHU9950 Dishwasher

1 Answer

Access controls how do I remove the "cover" of the SHU9950 in order to acess the control buttons. My on/off switch button has gotten stuck. I can "pop" the back edge free but the front, which lays against the front door panel, will not come free.

Power Supply

The main power supply is the first thing to check. Also remove the toe kick and the cover on the power box and check the connections. Also check for 120 volt at the power box.

Hi - Limit Fuse

This will fail if your dishwasher overheats and occassionally with power surges. This is easy to check, inexpensive and a quick fix. Just check the terminals for continuity ( remember always remove one wire) if you have none replace the hi limit fuse.

Door Switch

This is the second place to look. Again an inexpensive easy fix. The following video will walk you thru checking the door switch. The power comes into the main power box and usually runs to the door switch next before entering the main control module.

Main Control Module / Timer

The main control module or mechanical timer controls all the functions of the dishwasher. To check this you will need to find the 2 leads that supply the power to the control. They will be marked on the wiring diagram. They usually come from the hi - limit fuse or the door switch. When the door is latched you should have 120 volts entering the main control. If you do not the problem is not the control. If you do have power entering the control but none of the functions work properly or it does not respond at all you will need to replace the control module, this is easy to replace but not very inexpensive to purchase. Consider the age and overall condition when purchasing this part.


The motor may have failed. If the control illuminates on electronic versions the problem may be the motor. To check the motor refer to the tech sheet located behind the console cover on most models, this will sometimes have the ohm reading of the motor. Also check each lead to the metal housing of the motor to check for shorts in the motor. If you do not have the ohm reading specicifications, check for continuity if none replace the motor. Make sure the motor is recieving power.

Float Switch

If the float switch has failed or is stuck the dishwasher control may not respond. The float switch is easy to check and replace. We have video and tutorials that cover several styles.

Maytag MDBH945AWW: control panel was a bit erratic and now doesn't function at all. I pulled the flex circuit panel off and see that under the cycle select button is some brown gooey stuff. The other...

I have the same dishwasher. I have found that this dishwasher had a control panel problem. After the dishwasher finishes washing you will noticed that the small green lights stay illuminated. Over time this causes the wire ribbon that connects the control panel to the circuit board to become burnt. I have already replaced my control panel once and now it has done it again. i am about to have to order another control panel. That is going to be another $140 dollars out of pocket. The part number for the control panel is( AP4365240). If you have the same dishwasher as I do it should be correct, Open the front door and look on the inside left and you will see the model of the dishwasher. Mine is MDC4650AWB1 Yours may be slightly different. look on the front of the control panel to see if it reads from left to right. High temp wash or extra rinse, sanitize, heated dry, start/cancel, delay, and cycle select. Since the dishwasher is designed poorly and the lights do not go off after drying, if you can after the dishwasher finishes with it's washing and drying be sure to open the door for about 2 min and the lights will go out by themselves. Then you can close it back. This will allow your dishwashr to last longer without the wires burning out. To verify that it is the control panel after you carefully remove it take a look at the wire ribbon that runs from the control panel to the circuit board. Here is a quick class on how to remove the control panel. open the door and on both sides you will find 4 star tip screws. remove them and seperate the door from the backing. After that you will need a socket to remove some hex tip screws that holds the control panel to the door. be sure to remove the black box that contains the circuit board. take the cover off and carefully disconnect the wires. the wire ribbon that connects the control panel is a little tricky. You have to seperate the plastic connector block and the ribbon will slide right out. after you remove it go to and you will be able to order the part online to replace it. Be careful not to drop any of the screws and also pay attention to the door latch when you move it to the side while you work so that you do not break it.

This is a response to another similar question but it looks like the same prob. I have found that you cannot just get the buttons you need to get the control panel assembly. Iit it the "flex buttons" they are stuck on by some type of adhesive to the plastic panel. I found that if you just peel off the buttons it messes them up. you need to remove the plastic panel in order to disconnect the control panel from the circuit board.

Error code C1 PO......

Hello. Your model dishwasher has a recall on it. There is a potential problem with the control board. Call Bosch at (800)856-9226 to find out if your unit needs to have a new control board installed and re-programmed. This only covers the replacement of the control board--any other problem will be covered by the customer. You will need the model and serial number. Next, regarding your model's problem...this was gotten from another tech site(I'm a member of quite a few, lol)
"Sounds like the unit is stuck in the control coding mode. C1 is the proper coding for your model so you just need to lock it in.
To enter coding mode, press and hold the second, third, fourth and fifth buttons to the right of the display simultaneously, then turn the dishwasher on using the On/Off switch. The associated leds will be blinking to confirm coding mode.
Release all buttons to view control coding. To change coding, press the second button to scroll through codes C0 - C9. C1 is the correct code for your unit.
Turn the dishwasher off to save control coding and exit coding mode." I hope this helps you! Let me know if you need further assistance!---Thanks!

The control button labels are worn off. I would love to know what each button does.


The simplest thing would be to read the manual. This is available for download (free) from Fixya. Please click on the link below to open the manual:

You will need to scroll down slightly and there is a link just above the manual for downloading to your PC. You can then print the file and keep it with your dishwasher for future reference. If you are unable to open the file, you may also to download Adobe Reader:

Please rate this solution if you find it helpful. Thanks.

Replace Control panel cover on dishlex dishwasher 500E

If your 500E is the same as my 500E then the controls are electronic touch buttons. The are part of a self adhesive strip and stuck to the front of the door. No screws involved. Only the LED lights are mounted on a circuit board with screws on the back of the plastic front panel. ?????

Is there a way to turn off the cycle completion signal. I have a Bosch SHY66C02UC/14

OK, I think I have figured this out. Let me first give this important piece of information. The control panel for my dishwasher was replaced recently. That's why I now have to deal with this issue. I have a Bosch SHY66C model. As I stated in a previous post, the user manual I found on the web has identical structions for changing the amount of rinse aid dispensed and for changing the volume on the cycle completion beeper (or for disabling it). Following the instructions fixed the former.

Here is what I did

1) With dishwasher off, I pressed and held the "Delay Start Hours" button
2) I pressed the on/off button. The beeper begin to sound.
3) I released both buttons (not sure this step is necessary)
4) I repeatedly pressed the "Delay Start Hours" button until the signal turned off
(LED display showed 0)
5) I pressed the on/off button (not sure this still is necessary)

That seems to have fixed the problem. So, I don't know if the user manual is wrong or my control panel was replaced with one from a different model (such as the SHU9950 where I found these instructions).

Bosch Dishwasher on/off

It could be the switch. If the black plastic On/Off button comes all the back up into cutout in the top of the door, you must remove the front of the door (10 little screws; two shims will probably fall out; good luck figuring out how they go back) and then the plastic top (4 little screws) that contains the On/Off and the wash mode buttons. Now you've exposed the real on/off switch, which has a reddish/brown stem (at least on my unit). Test the switch; if the DW doesn't stay on when you depress it, you need a new switch. If it stays on, then goes off when you depress it again, the switch is likely good and maybe you have a problem with the black plastic cover button.

P button stuck

The P button is a part of the control board. You should take apart the control board and see whether the P switch was just stuck and you can fix it or you should replace the unit. Good luck!
