washer washes OK but does no longer spin
Hi
I have been reading your article Washing machine not spinning at end of cycle in detail, but I don't find the answer to my issue.
Hence below detailed description of issue:
I am having issue that my Asko Cylinda 11002 from 1991 with Siemens motor has stopped spinning, but washes and drains water OK. I.e. it proceeds to end of program. This issue has developed over last year or so, but now it does not spin at all. Earlier on it was spinning at 90 deg. program only.
So far I have checked:
3 rubber pipes to level switch N1 and N2 – ok
Y connection – ok
carbon brushes of motor – ok
driving belt OK (checked when motor was removed to check brushes)
No abnormal from motor or machine during washing.
pressure chamber clean – no blockage
noise capacitor (100 nanoF 50 OHM) burnt and replaced with 100 nanoF 2.2 M ohm (since I could not find the original one so far)
Any further ideas would be appreciated.

Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Asko Cylinda 11002 washed and drained but would not spin
- The problem
- An Asko Cylinda 11002 (1991) with Siemens motor completed wash programmes and drained normally, but spinning had progressively weakened over about a year and eventually stopped completely. It had previously only spun on the 90 degree programme.
- Likely cause
- Confirmed motor fault. The original poster found the brushes were serviceable, but the motor would not take speed, indicating the problem was with the motor rather than the PCB/timer.
- What fixed it
- A refurbished motor was fitted, which solved the spinning problem. Earlier advice was that, after other checks had been ruled out, the main suspects were the motor or PCB, and speculative replacement was not recommended without diagnosis.
- Checks to try
- 3 rubber pipes to level switch N1 and N2 checked OK
- Y connection checked OK
- Motor carbon brushes checked OK
- Drive belt checked OK
- Pressure chamber cleaned and found clear
- Machine washed and drained normally
- Noise capacitor had been found burnt and was replaced
- Parts or tools mentioned
- Refurbished motor
- Noise capacitor
Safety: Do not attempt external motor testing unless properly qualified. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hello. The article contains all possible causes of the fault. It sounds like you've eliminated several things which leaves faults on the motor or the pcb as suspects. I would not recommend speculatively replacing any of them though. It's just too risky with the cost of the parts with no guarantee of a fix if you haven't been able to confidently diagnose the fault.

Thanks Andy for fast and constructive response.
One question: when you say PCB I guess you mean timer module?

Hello Peter. Most washing machines are controlled by PCB power modules now. If it's one with an old style timer they usually work in conjunction with a separate pcb.

Hi Andy
I found solution to spinning problem. In my case brushes were OK, but motor would not take speed. So motor was the issue not the PCB/timer.
Seems to be well known issue that when induction motors like this are getting worn they may not spin at higher speeds.
It needed a helping hand when checking it in external test setup, see e.g. http://www.how-to-repair.com/help/how-to-test-a-washing-machine-motor/.
So I found a refurbished motor, which then solved the issue.

Thanks for the update Peter. I wouldn't recommend anyone trying the test rig though unless they really understand what's going on or your motor is exactly the same as the one featured. Good video.
