Thank you Grand Master! I cannot find a schematic for this dishwasher anywhere. Has anyone seen a schematic for ANY of the Bosch dishwashers? Couldn't find the Tech Sheet during disassembly either...

The Bosch site lists schematics for many of these model species but, for some reason, does not list any schematics for this /23 species.

Scott,

I got my butt handed to me yesterday by this machine.  Same model, but a 21 series. (SHX46A05UC/21) I think the main difference here is the wash motor.

Customer complaint was no drain, no wash.

I arrived and unit was full of water.  No tech sheet.

From the "Bosch SHE Dishwasher Service Manual 58300000148618" linked above, and marked on the control.  I hit the "scrub" and "delicate" buttons to initiate a drain.  The drain pump would run intermittent.  I'm not sure how this unit operates.  I thought the drain pump was running intermittent to measure amp draw of the drain pump and determine water level.  I ended up clearing a drain line obstruction, and got good flow, but still had intermittent drain pump.  Not sure if normal, inconclusive test for me.

I tried to run a cycle, with test leads on the wash pump and unit never seemed to advance to wash, i.e. no power to wash motor.  I messed around with the control and finally gave up. I ran a cheater cord to the wash motor and got GREAT wash performance.

I said ah hah!  Wash motor runs when powered, but wash motor not getting powered. "It's got to be the control board."

I don't think this unit has a "power module"...but did not look.  I'm hoping it's integrated with user interface.

You mentioned the "Bosch site" above. Is there an exploded view, or parts look up for Bosch? 

Annoyingly, my regular PD's (Servall, Sundberg) sell parts, but don't have look ups.  I haven't found lookups elsewhere.  

Thanks!

There sure is... they call it the "Quickfinder."

Here is a schematic for this model:

Thanks Nathan,

should have figured you'd come through. 

Couple follow up questions.

1) I see quickfinder needs a login. Is that authorized only?  

2) that schematic is little confusing to me with the word "modules". It looks to be an integrated unit, but the schematic shows wash pump getting power from K4 module, which isn't listed in the legend. Do you know if that's a separate high voltage module, or just poor documentation?

3) lastly a rookie questions. Are those "modules" listed on the schematic really just relays on one board?  If so what does the "d" symbol represent on the modules?

thanks for the help!!!

Ya, these German diagrams are a bit different: "modul K1 and K3" are the displays. "modul K2" is the control itself and it has K1, K2, K3, and K4 relays mounted on it.

The little "d" on the relays may represent the solenoid coil and the contacts inside the relay... the symbol is likely negligable OR they would have put it in the legend. 

K4 is a board mounted relay- it runs through the terminals just like K2, K3, and K1- they are indicated as board mounted relays by the rectangular dotted lines...
