  • did destroy mine by turning program-button manually to the end while drum was rotating at full speed 1000/min + well filled…
  • effect:
  • coming from the motor: crackling sounds and flashes visually reflected by the floor…
  • and: !…FROM NOW ON: NO MORE LIVE IN THE DRUM…!

Step 2

checked all available online data -not much!-

Step 3

  • Disconnect the washer before proceeding.
  • get your tool-box: open a line of screws at the right rearside PLUS one at the right frontside hidden under the a broad plastic panel…
  • now you can put off the right side cover
  • deep down at the rear behind a watershield and an alu-capacitor is the control-unit: eaton a1 d20
  • first vacuumclean all inside then open one clip with two fingers and flip the watershield up -out off your way-
  • get lamp and find the broad plastic clip to press to get the control-unit loose -way deep down in the rearside-
  • fiddle it out
  • on the control-unit-plastic: press two clips to separate the pcb from plastic…

Disconnect the washer before proceeding.

get your tool-box: open a line of screws at the right rearside PLUS one at the right frontside hidden under the a broad plastic panel…

now you can put off the right side cover

deep down at the rear behind a watershield and an alu-capacitor is the control-unit: eaton a1 d20

first vacuumclean all inside then open one clip with two fingers and flip the watershield up -out off your way-

get lamp and find the broad plastic clip to press to get the control-unit loose -way deep down in the rearside-

fiddle it out

on the control-unit-plastic: press two clips to separate the pcb from plastic…

Step 4

  • a small metal clip presses the triac btb15 600 bce to the heat sink. open this clip
  • use multimeter to check integrity of triac: view from front, left to right reading: read PIN 1 to PIN 2: 1,3 MOhm and PIN 2 to PIN 3: 1,3 MOhm and PIN 1 to PIN 3: 54 Ohm ( PIN 1 and 2 are Anodes and PIN 3 is Gate)
  • if strong differences to these values you found the first candidate to replace
  • get new triac btb15 600 bce or equivalent -important properties!: 16a, 600v minimum ISOLATED CASE?! CHECK IT!!- eg: tic 246 m , bt139-800 , mac15-4 , t6001d … desolder original and put out and replace it by new one -equivalents may have different order of pins t1, t2, g -CHECK IT!!!- … REUSE “WHITE FAT” (heatsinkpaste) AT OLD & PUT IT TO NEW..
  • re-attach the metal-clip , put pcb and plastic again and snap in and fiddle it back at its place deep in the machine…
  • check machine: plug mains and start a program… if drum turns again you are ready… if not:
  • maybe the control-ic on the control-unit is dead, too BUT I FEAR: then we are lost: it is from zilog: zilog 2412 eaton cm 20a -can you find a subtitute???-
  • and maybe the motor got a shot, too… then you had to put out the motor, maybe the commutator got bad: then it needs rearrangement, you need 120 grade sandpaper (…how to do? look for instructions elsewhere)… and/or maybe you just need to replace the coals and put it in place again…

Step 5

  • it turned out: the triac was blown -short circuit- i only got a tic246m, has NO ISOLATED case… -DANGER!! MAINS is on the heat-sink!!! and thus waterdrops around could make troubles: so i recommend go for an isolated case…!! AND: tl 60 thermostat limiter in the motor: in line no 3 & at the lower motor coal (two white cables) was blown, too.
  • i decided to leave out “tl 60 (degrees celsius) thermostat limiter” completely because where the washing-mashine stands it is quite cool, AND i wont expect too high load on it neither to make the limiter act… though i recommend for you in case it is blown, too: get and mount a substitute!!! …anyway…
  • good luck!
