siemens topline washer dryer

[miadane99]

Ok I have a Siemens topline washer dryer E-Nr. WK 61420 GB /13 FD 8211 400097.( its about 12 years old)
It stopped spinning-at all-so after much checking on the net , took it apart and checked drain pump which was clear ( machine pumps fine ,little noise)
Then moved onto brushes which as it turned out where worn down ( unevenly ?) One of the bushes had only 6mm left. Apparently according to the guy in the shop siemens change motors in their machines on a whim and mine was fitted with brushes fixed into a plastic housing and then into the aluminium end part of the motor and could only be bought as a single part …….that will be £ 72!!! .
So fitted this and checked for free running and refitted the motor and belt , quick check with pictures taken beforehand and everything ok .
Reassemble and replace in slot (its an integrated unit)( yes its heavy,awkward etc…)
Machine now spins in for about 15 seconds on spin cycle and then stops , on wash program will start to revolve then stop.
Cannot move program through cycle ie wash/rinse/final rinse/spin when it stops it has to be turned off and on again to advance . Can be pumped out to empty machine.
Do i check the suds pump from the back and disassemble the complete pipework?
The door needs to be slammed to start the machine,could a flaky door switch be the problem?
Thanks for any thoughts.
The dryer has packed up as well but its not important……unless it is!

by the look of it its a new rear end for the motor part number 496876 £58.86 from siemans

if it was this it sounds like the motor tacho is not working. the tacho is a magnet at the back of the motor armature that spins in a coil. it feeds a signal back to the electronics. make sure the magnet has not been damaged and check if there is an output with a multimeter

I am fairly up with most diy and own a meter but dont understand?
Can you explain in simpler terms please( sorry am now 54 and things dont get remembered like they used to be )

Re: siemens topline washer dryer

the tacho small generator that generates an ac voltage

there are 6 or 7 pins on your motor which are as follows

2 pins armature
2 pins (or 3) field coil
2 pins tacho

first use a multimeter on low ohms scale and find which pins join to which pins. ie hold meter lead on first pin then move other lead down other pins till you get a reading. keep doing this till you can say what all pins do. the tacho coil may need a higher resistance scale to detect
the lowest ohm readings are the armature and field coil so ignore these pins. set meter to a low ac voltage scale (millivolts), put meter leads on the tacho output pins. spin motor and you should see an output.
if you get a signal it is important you check the voltage get to the board so buzz through the wiring harness to make sure you don’t have a broken wire

Re: siemens topline washer dryer

At £72 you were ripped off. The part (as Dave mentioned) should have the part number 00496876, if it doesn’t you’ve fitted the wrong part and hence why it doesn’t work.

Re: siemens topline washer dryer

Not tested yet, but the other half has ordered a new machine SMEG WMI12C7 Integrated Washing Machine so its a bye bye to the old one.
Would still like to know what the problem was.
Other forum advice is the tacho or the pcb either of which is a £200+ bill added to the £70 already spent so common sense is a new machine, yes?
Will try testing over weekend and post results anyway.
Thanks for the help………scrap siemens anybody?( new brushes!!)
Oh yes my neighbour said last time i used washer it was very noisy(more than usual)
