I have a Bosch WFR2866 that will not go into wash but goes direct to spin. Set the program for a wash and the water fills and instead of the drum moving at wash speed, it goes into spin speed for a while then stops. It then it goes into reverse and spins again. Seems it cant engage low speed drum drive – always spin drive. Also notice that on drain out, water drains away but drum does not move which I think it should. Drum is free to turn manually .
Sounds like the Tacho has gone in the motor . When it does these ‘spins’ , are they very fast and quick ?

Yes the spin appears to be replacing what would be the wash movement of the drum. Spin lasts about 30 secs and is approx 800 – 1000 RPM ( guess work here !) . Drum stops then more water loads and drum then spins in opposite direction.
I will check the motor tacho tomorrow – can I get at this from the front or do I have to remove the motor asm from the rear of the machine
Re: Bosch Logixx 1400 WFR2866 Wash Problem
Have tried to meter the output of the motor tacho but access to it very difficult. Can I tilt the machine on its side and access via the bottom panel. Do I have to lock the drum when doing this ?
I have never removed a motor befoe so not sue he best way to attack this – any help appreciatedRe: Bosch Logixx 1400 WFR2866 Wash Problem
I removed the motor and then metered the pins on the connector. Pins 1,2 3 had about 2 ohms between each of them, which did not vary when spinning the motor shaft. Pins 4 and 5 varied from 2 ohm to 1 ohm and pins 6,7 varied from 23 ohms to 1 ohm when the motor shaft was spun. Pin 8 did not seem to be connected to anything?
I also checked the motor brushes whilst I had the unit out and although they are worn, there is still about 2 cm of carbon rod on each brush.
From this I can only deduce that the varying readings are the tacho and the commutator, as the motor shaft is spun and all would seem to be good in that there is some variation.
I guess this only leaves the control board which of course is fully electronic and very costly ( £250+)
Unless anyone else can suggest something, I thinks it time for a new machine as the board cost is at least 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the cost of a new one.
