Customer Question

I have the bosch dishwasher Model Number SMS69L22GB, this dishwasher has suddenly stopped working. There is no power on the programming display across the top of the door. I have tested the power module mains cord which tested ok with 240 volts on the end of it. I have now taken the module out and had a look at the PCB, which also looks good as this unit is only about 3 months old. Are you able to tell me how to conduct further tests on this unit, e.g. what output voltage I should see at what connecter and wire colour. Look forward to hearing from you.
Kind regardsJustin

The tech sheet for youe model is attached. Do you have power to the main power module?

Expert:  Kelly replied 3 months ago.

Will it start a test cycle at all?

Customer: replied 3 months ago.
Hi Kelly,
Many thanks for you speedy response. As I have just mentioned, there is absolutly no power on the control moduel panel. Therefore I would not be able to start a test cycle at all?
Expert:  Kelly replied 3 months ago.

Sometimes the test cycle will start when the other functions bring no result. It is a programming issue in the main module. So have you verified power to the main power module?

Customer: replied 3 months ago.
Ok Kelly. I can try the test cycle. Can you confirm which buttons i need to activate the test, as the spec sheet link does not appear to correspond to the dishwasher i have? I can only tell you that there is 240 volts coming out of the mains cable before plugging into the power module.
Expert:  Kelly replied 3 months ago.

Your control does not have the button layouts as shown on the sheet?

Expert:  Kelly replied 3 months ago.

You can test the electronics as well, the attached sheet shows how.

Customer: replied 3 months ago.
Hi Kelly,See attached what my Control panel looks like.
Expert:  Kelly replied 3 months ago.

So you would use the ECO, QUICK & PRE-RINSE keys, see the tech sheet, top panel.

Are we talking the same power supply here ???
Expert:  Kelly replied 3 months ago.

I cannot open that picture. You can use the ADD FILE button to add a photo.

Expert:  Kelly replied 3 months ago.

Did you try the keys on the panel I suggested?

Customer: replied 3 months ago.
I have not yet tried the keys on the panel, as I am currently still at work.
Please find attached the photo which in now in a PDF Format.
Which actual test do i need to perform on the Service Programme Sheets, I see three pages.
Expert:  Kelly replied 3 months ago.

Start at 1.2 on the 2nd page and see if the control lights up.

Customer: replied 3 months ago.
Nothing happens on the control panel, completely dead.
Expert:  Kelly replied 3 months ago.

Okay, so you will need to confirm voltage to the main control module and replace if that voltage is present. Let me know what you find.

Customer: replied 3 months ago.
This what i have been asking you? At what points on the power module PCB should I check for voltages and what voltage should i expect to see?
Expert:  Kelly replied 3 months ago.

Did you not see the sheet with the outputs I sent you a couple hours ago?

Expert:  Kelly replied 3 months ago.

I cant seem to relate your sheet to the actual PCB I have. Please see attached.
Expert:  Kelly replied 3 months ago.

The sheet I sent is test points on the board in between the door panels.

Customer: replied 3 months ago.
Please can you be more specific? Can you provide a picture?
Expert:  Kelly replied 3 months ago.

I will see if another has pictures available.

Customer: replied 3 months ago.
Thanks. Just don't get what you mean by door panels ??

Hi Kelly,Did you manage to find out any further information?
