Re: AEG Lavamat L16830 tacho problem

Hmmm 2 weeks after ordering, UKWhitegoods just told me Electrolux has no UK stock for the replacement tacho generator, a Zanussi one with part number 50229052001. Other suppliers told me it will no longer be available.

Can anyone salvage a tacho generator coil from an old AEG, Zanussi or Hotpoint washing machine for me? Should have a coil resistance around 184 ohms.

Cheers

Re: AEG Lavamat L16830 tacho problem

Got it fixed! Inverter board was fine… culprit was an intermittent bad contact inside the tacho generator coil. I hacksawed the coil housing open, cut off the old wires, and soldered on new ones. We have done one load of washing with it this afternoon. Fingers crossed that it keeps going.

Thanks for your suggestions!

Re: AEG/Electrolux tacho generator

Dave was very helpful… took down further details re the motor, and suggested a Zanussi equivalent for 15 quid.

I’ll see next week whether it does the trick!

Re: AEG Lavamat L16830 tacho problem

Thanks guys… I’ll try those tests tomorrow.

The motor is an ACC-labelled induction motor, 310V 3-phase 3A 17500 rpm. According to the AEG EWM3000NEW control board service manual, it uses the tacho to regulate speed, especially when establishing out-of-balance at the start of each spin cycle.

The motor controller board has a transformer, whopping big capacitor, and a heatsink with diode rectifier and 6 triacs. The board looks in perfect condition. No signs of overheated or burnt out components, no dry joints or damaged PCB tracks, etc.
