Bosch WFS4030GB/01 headscratcher :(

[Martin]

Little old lady has an immaculate washing machine thats about 11 years old, probably done about 100 washes in its entire life. But it will not spin 😥

Now the symptoms are :- Set it on a No1 Spin only prog, hit the start button…it skips neatly to the start of the spin then pumps for 60 secs, then skips through the spin phase and OFF 😕

It washes OK, fills, empties, heats, all the usual but no final spin. I have checked the valves, door interlock, motor, heater and pressure system are all OK :tup:

The problem is (I suspect) either the Control Unit or the Power Module but the trouble is, the former is £125 and the latter over £200 😯

Now those lovely people at Bosch Technical Department, are posting me (FREE OF CHARGE I MUST ADD) and Programme test sequence with error code info, so that will be a major step towards solving the case I reckon.

Meanwhile over to you wise guys out there to help me find a quick solution and make my ‘little old lady’ customer very very happy 😀

Sounds like an eeprom fault to me VERY expensive.Are there any lights flashing if so which?

Thanks boro,

In fact the guy at Bosch Tech Dept asked me the same questions, sadly I could not answer them, so he is sending me in the post a Test Sheet on this model so I can observe the light sequence error coding 😉

I know that in may well be the Power Board (Part No 285737 @ over £220) which I think is what you refer to 😕 The cost only becomes an issue in this case if I make a wrong diagnosis and get stuck with a part I cannot return. Spot on diagnosis therefore is essential BEFORE I order and replace whatever is wrong.

I live in the fervent hope someone will spot my dilema and post back to say…”Yes Martin, it is the blah blah blah that’s faulty, I did one just the same last week!” (I wish eh? :rotfl: )

Meanwhile I wait for the postman to come with the Test sheet, then will go back to the job and see what lights flash before my eyes when I switch on 😯

P.S. I doubt the BSH Engineer in my patch would have a module on his van I could borrow :lol2:

Postman delivered the Test sheet today :tup: Unfortunately it’s the wrong sheet, they sent me a Condensor Dryer Test sheet instead :tdown:

So for me that’ll be another hour on the phone to Bosch on Monday I expect :haier:

🙄 Oh if I could only borrow a Bosch CD for half a day, my lot who be a much more happy one 🙄

Hi Martin,
I’ve got the test program info that you want. I’ve not been able to email it but have printed it out and can fax it if you email me your fax no.

Geoff,

Really good news and thanks for your help 😀

Sadly my fax programme does not want to play ball so I wonder if you could either post a copy to me (see my www for address) or possibly even scan it and sent it me as an email??

Sorry to put you to all this trouble 🙁

I wonder also if you have any thoughts from what I have written as the likely fault? (No – I won’t hold you to it but have you got any hunches?)

:tup:

Copy in post today; I don’t have a scanner. Haven’t got a clue what’s wrong but I’d check the continuity across the armature & motor brushes first. faults on these machines are usually something simple like that rather than timer or modules going wrong by themselves. Also chech heater insulation resistance. Geoff

Re: Bosch WFS4030GB/01 headscratcher 🙁

Having received the test sheet from Geoff (roly16) I am no further forward :haier:

The machine works beautifully all through wash and rinse. Fills, washes, heats, drains and spins all fine and lovely. As I said before the darn thing is immaculate and rarely used in spite of it being 11 years old 😕

The test sequence showed no fault anyway but on close observation on the final spin it pumps out for 5 minutes, advances to the next stage (presumably distribution spin) and then the error lights flash as good as on Blackpool Pleasure Beach in October. Namely the 1200, 900 and 600rpm led’s flash in unison and alternately when they go out the 1400rpm led flashes and so on, for ever! It just sits there like a deranged disco deck 🙁

Trouble is these test sheets and sequences are suppose to tell you whats wrong but invariably they themselves are just guessing :con: . For example, if the 1400 led flashes all by itself the official Test Sheet Diagnosis concludes that as meaning, and I quote… “Various Faults!”

So it’s back down the snake to square one on this I reckon and the fault is as I thought before either the Programme Module or the Control Unit or the Power Module……..anyones guess?…lets toss a coin eh?

You got to hand it to Bosch though to be fair, diagnosing a 1400 led flashing as being VARIOUS FAULTS is a masterpiece of German understatement…(nice one Hans!)

VORSPRUNG DURCH TECHNIK ?….ich weis es nicht! vielleicht er is kaputt ich denke :rotl:

Re: Bosch WFS4030GB/01 headscratcher 🙁

Vorsprung durch technic ist nicht Bosch. Ich denke das Audi oder BMW ist.

Seriously though folks have you checked operation of the pressure switch and checked the pressure chamber/tube for blockage? If the pressure switch level 1 doesn’t open it won’t spin.
Also I have been told by a friendly Bosch engineer that any reduction in insulation resistance on the machine can cause weird faults. If you’re a DASA member you will of course have done an IR test before working on the machine but it may be worth checking the motor again & cleaning the carbon dust out of it if any. My Bosch friend reckons that if it isn’t any of these straightforward things it’ll be the timer and unlikely to be the boards as the top board is for motor speed control only and wouldn’t cause it to rapid-advance through spin.
Hope this helps.

Nice one Geoff,

Neat bit of info there from you and thanks for that. There is hope then after all. :tup:

Timer you say? Did you refer to the 094413 Control Unit by that?….Just to clarify?

Do please tell me you are pulling my leg on that one :rotl:

Ich denke dass Sie mein Bein ziehen!

Martin

Vielen danke fuer ihre hilfe liebe Geoff 😀

Wot? Pulling your leg that you’re a DASA member or that you’ll have done an IR test before working on the machinejavascript:emoticon(‘:lol:’)

Re: Bosch WFS4030GB/01 headscratcher 🙁

Yes, 049913. But I think blocked pressure system is more likely. I look forward to hearing how you get on.
Best of luck.

Re: Bosch WFS4030GB/01 headscratcher 🙁

Its allright Martin, you dont HAVE to be a dasa member to carry out an insulation test…anyone can do it. 😆

Mmmmmm 😕 I haven’t checked that entirely I must admit BUT, if there were a problem in that area, why would it work OK throughout all other parts of the programme? ( INCLUDING the intermediate spins during the rinse cycle – which all work sweet as a nut)???

Dunno :con: , but will keep you posted.

Tschuess!

Good point; I can’t answer that one. But what’s more important is ; how do you get an emoticon in your message without it writing javascriptemoticon(‘:?’)laughing as well?/ javascript:emoticon(‘:?’)
Confused. see wot i mean?
