Re: Bosch WVG30461GB won’t lock and start
Hello Again,
So the problem turned out to be the main control board. The guy didn’t do any tests, he said he’s seen this same problem before, just got there took out the board put in a new one and bob is your uncle.
Since the machine is still pretty new, bosch provided the parts for free, and I only had to pay the callout fee of 95£. So it wasn’t bad after all.
He suggested it might be one of the relays misbehaving on the old pcb, I went ahead and tested all the relays one by one, all seem to be working fine. When I find a bit more time I will play with that pcb a bit more, to see if I can discover what was causing the issue, it is a fun exercise, but there is a lot of super tiny smd components on that board, so it might not be that easy to figure things out…maybe I can serial connect to it,a nd see if it is spitting out any errors on a serial monitor…Re: Bosch WVG30461GB won’t lock and start
Oh yes these are the ones I meant, sry I called it nozzle as I didn’t know the proper name, but yes it is the wires going into the metal conduit above the drum.

Hello John, I did indeed disconnect that (or at least I think I did, isn’t it the multiple plugs going into the kind of nozzle going out of the dryer blower?), and the result was still the same.
Re: Bosch WVG30461GB won’t lock and start
Hello again, just to give you an update. so I went ahead and worked on it a bit more this last week end, the problem persisted if I had disconnected the motor board completely, but then I worked a bit on the control board, disconnecting cables, testing, trying to clean plugs (they weren’t dirty or anything, just though it might be a lose plug or smtg). reassembled everything and low and behold everything works as expected. we did a few washes and 2 days later the same problem is back!! so I redid similar manipulations to what I had done the previous time, but this time there is no luck I can’t get it to work again, I thought of doing a reset but couldn’t find the procedure for it, and thought of running the test programs but I couldn’t find their descriptions anywhere, and it seems most of them don’t run because of the existing problem (as the machine can’t lock properly)
So at the end, I called up bosch and they are going to come over and have a look. I will let you know what it turns out to be.Re: Bosch WVG30461GB won’t lock and start
Thank you very much for your time and the reply. You are bang on, it is indeed the 01 model.
I had a look at the left hand side PCB, haven’t had a look at the right hand side one, because as you said it is the motor control board and in my mind the motor is working properly, I didn’t realize it could have that effect on the rest of the system. I will definitely check it out during the week end.
When you say disconnect the wires? which ones do you mean? as I had disconnected the different parts of the machine one by one to see if anything would change, and it didn’t as far as I know. or did you mean the earth wires?
The thing that is confusing me the most is that when I force the interlock to think it is locked, most of the time (as I have to try a few times every time I want to run it) the machine runs normally. without that override it never runs.
My last question is: when the interlock clicks twice, is it locking and then detecting a fault somewhere so it unlocks, hence the second click. or does it attempt a first time to lock, detects that it didn’t manage to do that and then tries to lock again hence the second click?
You’re right, if this week end I couldn’t solve it, the next step would be to call bosch in, let them fix it and try to understand from them what the problem was.
Regards
