Re: BoschWFK2801 washing machine

Greg,

Thanks for coming back to me,

Took the motor off this morning to have a look at the brushes a bit easier on the work bench. I was surprised to see such a lot of brush left after 7 years they both potruded from the brush carrier by at least 1/2 an inch long which I would think should be adequate ?

I cleaned the com up and reseated the brushes.

I also looked at tacho ?on the end of the motor (these bosch are clever stuff) removed the end cap and carefully wiped it after replacing it I checked the output by rotating the motor whilst connecting a DVM on AC Volts not acurate but it did fluctuate so indicated some kind of output.

Still at a bit of a loss with this vibration which whilst not being huge it is surficient to shake the powder draw open.

I wonder of it could be the drum bearings grasping the iner and outer drum there does appear to be a very slight ammount of play although this does seem difficult to check.

Should there be no play and not end float ? and whats it like to change the bearings on a drum ?

Many Thanks

Have a good weekend

Hi Greg,

Many thanks for the reply,

I think I understand what you are saying if the bushes were worn which is possible on a seven year machine as it has not had any previous work.

Do the brushes have a min lenght ? I assume as they wear the pressure on the brush spring decreases I have changed some on hotpoints before and always thought the spring loaded brush carrier on those was a bit daft some times jaming a different league of machine.

Many Thanks

Zeberdy
