Bosch WFF2000 Removing brushes

[BigE123]

Hi all,

I have an old Bosch WFF2000. Full make WFF2000GB/12 FD 7708 03872

A few years ago, the machine started skipping cycles, this was cured when an engineer came and replaced the brushes.

However the problem has recently come back. Machine goes straight to the end of of the program after the main wash, without spinning. If you manually click the selection wheel round to after the main wash, the cycle then finishes normally.

I have taken the motor out to check the brushes. I know this may not be the problem, but thought it would be the easiest thing to check 😀 , maybe the replacements were not up to scratch !

How do I get the brushes out ? Do I need to take the motor apart to do this ?

Thanks in advance

Two different motors fitted to this machine.

The “FHP” motor has the brushes in two black cartridges on the end of the motor.

The Siemens motor may have two white sleeves protruding with wires on the end. Removing the wires allows you to fiddle the tags free and pull the brushes free.

The early version has the brushes mounted internally on a plate – dismantling the motor is the only way to access them.

Thanks for the quick reply

My motor does have the white sleeves with the wires attached protruding. I have had a fiddle, but still cannot see how they should come out. I don’t want to force it and break anything.

Once I have pulled the wire off, the little clip that the wire was attached to, moves quite a lot. It appears to be on a spring, and the end that was not attached to the wire, pulls out of a slot on the side of the white sleeve. It spring back in when I let go. But that is the only thing that moves.

I haven’t opened the motor, as I don’t have the correct size screw driver, it is one of those star screws. (Got a set on order)

Anyway while the machine was apart, I decided to check the hoses and plastic box, between the inner hose and outer hose. All main hoses and box were fine, (box was de-gunged a couple of years ago when engineer called). However there is another small hose (about little finger size) that attaches to the top of the plastic box. The tiny hole (in the plastic box) to this hose was solidly blocked. I unclogged that, and put it all back together and hoped that would sort it out.

Unfortuntely not. I Watched it finish the main cycle, then it clicked round to the end as before. This time I watched for the prewash error LED.

It seems to blink 2 times, first time on for about 2 seconds then second time on for about 1 sec, then off for about 2 secs.

Hard to tell if this is supposed to be one blink or 2 ?

Any ideas what this indicates?

Thanks again for your help

Hi,

I have checked this out more carefully, and it is 2 blinks when the cycle skips to the end. What does this signify ?

thanks for your help

Cheers

Hi
Pre-wash lamp 2 blinks = fault in the heating circuit.
Machine usually with this fault, faults after 85 minutes.

Re: Bosch WFF2000 Removing brushes

Hi Greg,

85mins sounds about right, is that likely to be something like a new heating element needed ?

is that easy/cheap to replace, or is it time for an engineer?

Cheers

Re: Bosch WFF2000 Removing brushes

Hi
Most likely the heater, a check with a multimeter should reveal app 30 ohms.
Access is from front, so no need to pull appliance out 😀 not a bad job IMHO, if in any doubts there is always the engineer link below.
Heater if required is p/no 263726 – £27.90 +VAT +costs and is available from spares@ukwhitegoods.co.uk

Un plug appliance before attempting any work on it. :plug:

Re: Bosch WFF2000 Removing brushes

Hi Greg,

I have a multimeter, so that is something I can check.

You say access is from the front, is it easy to get the front off? I have only had the back off up to now. Is the heater obvious ?

many thanks for your help

Hi
Yes and yes 😉

Re: Bosch WFF2000 Removing brushes

Hi Greg,
as far I was aware, the heater is accessable from the back on the WFF2000. Sure you’re not getting it mixed up with the WFB2000?

Re: Bosch WFF2000 Removing brushes

Hi Dave
You are absolutely right.
Heater is accessible from the rear on this appliance, sorry about that 😳

Cheers again

I replaced the heating element on my WFF2000 a couple of years ago: buy the new element first so that you can see how the thing fits… otherwise you’ve no idea what you are trying to remove… but essentially, nothing could be easier.

I’ve also been looking at brush replacement: you’ve already had the motor off so the procedure appears to be as follows:

1. Uncrew the four long bolts allow you to seperate the casing (aside from a single, large washer at one end, nothing pops out or makes re-assembly difficult).

2. Remove the four machine screws holding the plastic panel in place and rotate it out of the way.

3. Remove the brushes in their housing: two machine screws each.

You COULD get hold of replacement housings (complete with brushes) for about £20+vat… but the cheapest option is apparently as follows:

The advice is merely “Ensure that the tension springs give you full travel before re-assembly”.

Re: Bosch WFF2000 Removing brushes

Hi GandG , that is a good description but not applicable to the motor this person has . The brushes on this motor are much simpler to remove/replace , only needing a wire tag removed and then sliding them about a bit to get them out .
Penguin explains this earlier in the thread 😉

i’v got the exact same problem same machine it skips the spin cycle, so is it motor bushes or heater element

Re: Bosch WFF2000 Removing brushes

Test meter time…….. which one hasn’t got a circuit through it?

Power off, please.
