My AEG Electrolux Lavamat L16830 washing machine (circa 2007, model s/n 914602122) won't spin. It gets to the end of the wash cycle, tries 5 times to spin, then resets itself with an E59 error code (no signal from tacho for 3 seconds).
The diagnostic modes that involve spinning similarly fail with an E59 code.
With the help of service manuals found on the web, I have taken the machine apart and measured the winding resistance of the motor (5.4 ohms between the X-Y, Y-Z and Z-X windings, right on spec) and the tacho generator (should be 121 ohms; I measure 246 ohms). The tacho generates a voltage when I rotate the motor. There are no signs of loose/missing tacho magnets.
It looks like the motor is working fine as it agitates normally during the wash cycle. It is just the high-speed spin that doesn't work.
On the basis of this, should I try to get/salvage a new tacho generator? Or should I look further to the motor controller board first?
On the offchance someone with a multimeter has a spare Elextrolux motor around, any chance you could measure the tacho's resistance?
Thanks for any advice
