I have a Bosch 500 series washer model number WFVC5400UC/24.
The drum that holds the clothes and rotates is rubbing against the rubber front seal (bellows).
The problem showed up as the drum stalling when spinning.
I found the front of the drum where it meets the front seal was very hot, too hot to touch.
I removed the front seal and I can see where the drum has been rubbing.
It has been rubbing and has worn evenly all the way around.
It is as if the drum has slid forward towards and against the front seal, but I can't feel any axial play in the drum.
When I move the drum up and down, I can just barely feel a little play in the bearings.
I have ordered a new front seal, and found that it has a new part number 00701333 which replaces 00678367 and 00674705.
So there have been changes in the part.
None of these numbers are on the old part, so I don't know what part number it was, but it looks original.
The new part hasn't come yet, so I can't see if it is thinner where it goes against the front seal.
I would like any guidance you have for me.
Can the drum have shifted forward against the front seal?
Should I replace the bearings now?

More correctly it is a Bosch Vision 500 Series model number WFVC5400UC/24.
Serial number is 850050087418005083.

I took the front seal off and measured the disstance between the edge of the drum and the lip of the tub.
It's only 0.14 inch (3.6 mm).
That seems too little to allow for the thickness of the seal and some clearance.

Hi,


I've never worked on or had training on Bosch Washers, hopefully another tech that works on Bosch Washers day in and day out can shed some light on this for you.

Thanks for your comment, Jake.
The new front seal turned out to be identical to the one I have.
I found the cause of the problem when I removed the drum from the tub.
There was a big build up of corrosion of the spider between the spider and the drum.
As the corrosion occurred, the corrosion products expanded and pushed between the back of the spider and the drum.
This distorted the parts and pushed the tub forward.
The back of the spider was badly corroded.
I would have replaced the spider, but Bosch does not sell it separately, you have to buy the whole tub complete for about $600.
So I have cleaned it up and reused it for now.
I'm going to keep looking for a good used one.
The clearance between the front of the drum and the seal is back to normal
I think the corrosion was caused because my tenant used a home made cleaner of equal parts borax, caustic soda and liquid soap.
This also caused blockage of the sewer pipes by a concrete like mass a year or so ago.
I think this mass also built up between the spider and the drum and kept things moist and alkaline.
Never again!
I'm including a picture.

Excellent, good find. (y)

Yes, I used to see that corrosion on the old Frigidaire spider support arms and it would eventually crack and break.
