Bosch Logixx7 washing machine

where the brushes worn down to nothing ?

Dave

was this the original problem or has it changed since you fitted parts ?

Dave

well Bosch fault codes are hard to get

next thing i would check is the thermistor

how does the fault present

turn on fault there
or
turn on set programme and fault only there after pressing start

does the door lock ?

Dave

Ah you may have something

would you say it tries to go into spin while full of water. Is it that violent ?

Dave

that sounds like the tacho on the motor is not feeding back to the timer

you would need to test the motor tacho output is there

the tacho is a spinning magnet in the motor that turns in a coil. this generates a small ac voltage that feeds back to the board. if this voltage is not there the module assumes the motor is stationary and accelerates it

am thinking the magnet may have split which is part of the motor

Dave

well i assume from what your saying that before it would start and run violently but now it wont run

sounds like it needs resetting and there is a safety lockout on motor problems. It wont cure the original problem but it will get it going again

you can search for bosch resets and see what you find. would need to see control panel to try to guess which proceedure may work

Dave

thats means its a motor fault of some kind

still think the voilent movements are the start of it
its possible its blown a circuit board track through high current flowing when the motor was speeding

to go from here depends on the tools you have and skill level
