Bosch WAE24162GB/03 Auto – Tacho fault?

[MickGeorge]

Hi folks

Went to this today got what seems to be a tacho fault – no spin, suddenly goes into spin with no distribute and then cuts out for about 30secs and does the same – keeps this up for three times and then switches off.Typical tacho fault I would think?

Checked tacho winding, term block connections, magnet (what you can see cuz its all covered in) seems ok as managed to get small screwdriver and hold magnet while turning motor, no earth fault on tacho or motor windings, checked and pulled wires where they are secured for a broken wire (had that one before) but all checking out ok.

Am I looking at motor or module or have I missed something? Just wondered if any of you Bosch experts out there had this one before?

Any help appreciated

Thanks

I wouldn’t think its the tacho but the wiring to it that’s the problem. Have you checked the motor wiring harness back to the module to be sure all wires are connected?

Thanks for the reply Martin

Did check at the module and make sure they were connected ok and not got disloged also shone torch along wiring as far as i could see it all looked intact.

Was pretty convinced it could have been wiring but couldn’t see anything. Did think about trying to make a clip and wire so I could short individual wires to earth to check continuity – either that or a long wire for my continuity tester 🙂

Even thought about cutting the wires by the securing clip and reconnecting them just incase but all seemed a bit drastic as usually I can find a broken wire by pulling the wire and the insulation streches like elastic where the break is. Also checked wiring at motor block to see if tacho wires had broken.

Machine only about 3 years old btw.

Suppose what i am trying to say is anyone had anything else cause this fault other than a broken wire on these machines?

Anyone?

It’s essential to carry out a full continuity check of the wiring harness from motor to module, visual inspection falls short of establishing with certainty of course. Also remove the motor brush housing completely to check the pins are connected to the tacho coil and that the magnet is intact.

Reassemble motor, plug harness back in and again check continuity from the module end prior to final connection. 😉

Been back to this today – double checked wiring, did continuity readings from module – had motor off checked magnet – even tweeked the wipe on connections at the module incase it was an “indesit” connection 🙂 all seems ok though so suspect module.

Funny thing was when i first switched m/c on after been left 4 a couple of days worked ok for about 45 secs then started to play up again which is making me suspect something breaking down in module as magnet eliminated.

Do these modules come pre configured or do i need some cofiguring info?

Also looks like 2 moduled listed Conrol module & Power module – no picures so I asume it would be the power module required? control module must be the facia controls?

Any coments appreciated especially if you have had the module cause this fault.

Thanks

Fairly new m/c so I personally haven’t had a problem like this before. The module is part no: 675135 at around £75 so not expensive and would probably be configured already (if not instructions on how to are usually included in the box – if you buy direct from Bosch that is. :rolls: Buying from Connect you’ll get nowt in the box but Spanish and German guf)
