I keep going to Bosch washers (3-7 years old), where the interlock has blown and taken the brain with it!
Does this sound familier to anyone else. I hope not, because I’ve sold hundreds of these Bosch, and I cover them with my own warranty.
Luckily none of ‘mine’ have had this problem yet.
Re: Dear BSH-Man…..
I think you’re having a laugh here :con:
BOSCH INTERLOCKS????BLOWING THE MODULE?????…pull the other one….(What models anyway?)
Re: Dear BSH-Man…..
I assure you, it’s very true.
At first I thought it was a freak occurance, but I keep getting more and more of them.
Any model with a selector switch instead of a timer. The whole machine is run off a PCB in the facia, and when the door lock goes ‘OC’, the PCB gets big patches of track blown off it.
And yes, I’ve tried resoldering the track, but it never seems to work, because of fried chips. (Hmmmmm, fried chips.)
Re: Dear BSH-Man…..
I have only had this once on a 5 year old WFG2020GB/01. And it does indeed fry the chips especially on a friday night, but no way is it common IMO
Re: Dear BSH-Man…..
Im praying it’s not common.
I forgot to say, the first one I (the boss) had was on a Siemans. Same thing, selector switch, PCB, faulty door lock, splattered brain.
The boss, (in his superior wisdom) told the owner to get BSH-man to it.
Because this was our machine, he went back after for a progress report. Apparently BSH-man had blown up a new PCB before putting a door lock on it. Not UKWG’s BSH-man of course. This was about 5 years ago, went nobody had heard of this problem, I think not ever BSH-man, since he blew a PCB.
The thing is, the boss noticed the old PCB was covered in carbon dust from the brushes, and wondered if this had contributed to the problem.
Re: Dear BSH-Man…..
In seven years of working for BSH I’ve never had a door lock blow a PCB.
Honestly,it’s a new one on me. :con:
In fact I could probably count on one hand the amount of door locks I’ve fitted.
Re: Dear BSH-Man…..
I have had this happen only once, about four years ago on a top spec Bosch appliance (the one with the solenoid door lock).
I was the returning engineer, the first engineer had found blown tracks but no other fault and ordered a module.
I was cautious and had a good look before replacing the control module.
To my surprise and found a dead short (not o.c.) on the interlock. 😯
Never had it on the more common type of lock though. :con:Re: Dear BSH-Man…..

Chris.
Yea, Kamikaze antics.
Re: Dear BSH-Man…..
Last five Bosch machine…
Two with very worn brushes taking the board out
Three with………board blown via the interlock connections.
Maybe its just those Lancs built Bosches. 😉Tony C
Re: Dear BSH-Man…..
OK! Thank you people.

…well three. My mind is at rest now, knowing I’ve just had three freak occurances.
Like I said….It’s our top selling machine, and we have lots covered by our own warranty.
It good to know I might not have to buy new PCB’s for all of them. 🙂
Saying that…..The inner bearing seems to collaspe alot, on the stainless steel tub model! 😉 We have a very, very soft water and over-soaping problem in this area though.

Bearings failed on low spec appliance?
We have had a few fail on this Spanish produced model.
Steer your punters to the safe mid range zone.
😉Re: Dear BSH-Man…..
Goatboy,
What models ARE you talking about anyway? Interlocks do not take out modules on any Bosch as I have said before (IMO) only low insulation armatures will take out a module/programmer anyway. Besides carbon dust never gets anywhere near a module?
Bearings?….Only the WFB series of spanish rubbish and elderly or well flogged WFF’s will need the odd bearing kit hammering home.
So I’m really curious as to what models you (“top selling machine”) refer to here ❓
Re: Dear BSH-Man…..

We have had a few fail on this Spanish produced model. 😉That’s the one’s! Not many bearing problems though. Mostly on Spanish stuff with the steel tub.
IME the plastic tub seems alot more reliable.
Martin, I’ve had three cases where an interlock has blown the PCB. My initial point was, I’ve never had a interlock go faulty without it blowing the PCB, but I think I’ve just had three freak machines. And carbon dust gets everywhere! Even into the facia and covers the PCB.
My most popular machine is the cheapest Bosch (WFO2466 + WFL2066). People just won’t spend the money on mid-range models round here. Before them, it was the WFD2466 + 2066 I think, right back to before the Bosch name was on the market and there was a cheap spanish Siemens, and an expensive german tank Siemans (WH50640, I think). Now that german Siemens was a fantastic machine.
Re: Dear BSH-Man…..
Are the interlocks getting water on them ala whirlpool /Brandt style dribbles from the dispenser running down inside (you did mention the oversoaping issue)? If not what is making the locks go?
I am with Martin here, never had a Bosch interlock blow in any way since the really really oldV646 style with the square locks. and the odd dead machine due to an interlock failure. Bosch is now the most common make we repair and yet I have never changed a control board for any reason. (dont mention the dishwashers though)
