We have a Bosch SGI46M65GB (FD8712 00073). built in dishwasher (purch. 2007) and have this problem. The control panel shows 0 and pressing any buttons has no affect. The machine just doesn’t run.
As everything was dead and no error code, I made the assumption that the control was duff and so have bought a new one from Bosch. Fitted it and turned on to set the model as per the instructions which came with it and the machine ran but I couldn’t get it to go to the model setting mode as per the instruction with the new control. As I had started and stopped it several times, I then pressed the reset buttons and it went through the empty cycle and the control showed zero. This new control is now stuck on zero and doesn’t work. Is there a way of resetting the control or what do I do to sort this out?
Now thinking that the new control is broken as well or perhaps something else is causing it to be stuck?
Thanks. TrevorRe: Bosch SGI46M65GB/01 control shows 0 & nothing works
Have you checked the door switch if its not operating the machine may not know the door has opened and will not set programme
just a thought

I am assuming door switch is OK as machine worked with new control until I reset.
Thanks for the suggestion and it did occur to me that I should have checked tthat out before splashing out on a new control unit.
I also checked that the wire gauze in the inlet pipe wasn’t blocked. Note that this machine has the aqua stop fitted.

Can I ask: –
Does the control module still show 0 in the display?
If so, when you press the 2 reset buttons will in drain for 60 seconds?
Re: Bosch SGI46M65GB/01 control shows 0 & nothing works
Hi Martin
It shows 0 all the time. Pressing reset buttons does nothing. Pressing any button or buttons does nothing. No response at all from the machine.
If you look at my first post, you will see that it worked with a new control but I couldn’t set the machine model and then when I reset it just went back to how it was with the original control so I have now put old one back in.
Regards

That rules out the door switch and on/off switch then. I conclude therefore the new module is now as duff as the old and that a component within the machine has caused then both to blow! 🙁
Careful inspection of the surface components on each may show similar/identical damage.

Hi Martin
My thoughts exactly. I will closely inspect the circuit board and components but I suspect it’s £90 down the drain and now I reckon it’s probably engineer time.
Thanks

I undid the dishwasher waste pipe from the U-bend on the sink today and found it blocked. Perhaps not fully blocked but there was a large lump of fatty gunge in there plus other fatty deposits.
Maybe the pump overloaded when pumping out and blew the controller as of course it still doesn’t work and it is stuck on zero. However, it had pumped out as no water in the machine.
Engineer coming on Friday so will hopefully find out what the problem is then, assuming he will tell me.
Re: Bosch SGI46M65GB/01 control shows 0 & nothing works
Engineer came and was going to plug a new controller in. I stopped him and told him what I had done – saved him destroying another controller. If you have made attempts to fix a machine yourself, it is best to tell the engineer as it can save them time and you money. I was worried he might refuse to touch it if he knew I had touched it but he was fine with it.
Turns out it is the water heater which is shorting to earth (large connector on controller) and has blown the controller so a new heater and controller are on the way to be fitted next Friday. Surely, there should be something protecting the controller from this sort of damage.
I took out the Bosch insurance for a year (before he came) and the cost of repair came in just under the maximum. If I had let him plug the new controller in, I guess I would have been into another controller and blown the limit and the machine would have been deemed as uneconomical to repair.
Spent enough as it is but at least insurance is monthly.
The engineer told me (I realised after I blew the new controller), that there is usually something which has caused the controller to blow and he told me that it is usually the water heater. i.e. controllers don’t usually just pack up on their own!
