Zanussi Motor Not Spinning
my Zanussi TurboDry 1000 does not spin properly. i have checked the brushes and they look ok, so now i am trying to figure out whether the motor is also ok. i am trying to do a continuity test as described here:
Zanussi washing machine: Model TurboDry W 1042 W Motor: MCA 38/64-148/ZN20 8 Pin connector Pin 1 : Brown Pin 2 : Blue (brush 1) Pin 3 : Light brown (brush 2) Pin 4 : Grey Pin 5 : Grey Pin 6 : Black Pin 7 & 8 : Red (these are thinner and seems like it is the tacho coil)
There is continuity between Pin 1 and Pin 6, i get a reading of 02.5 There is continuity between Pin 2 and Pin 3, i get a reading of 04.3 There is continuity between Pin 4 and Pin 5, i get a reading of 00.7
How do i know if the motor is ok from these readings ?
thanks very much

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Zanussi TurboDry W 1042 W poor spin with motor continuity readings
- The problem
- A Zanussi TurboDry 1000, model TurboDry W 1042 W, was not spinning properly. The owner checked the motor brushes and reported they looked OK, then carried out continuity checks on the MCA 38/64-148/ZN20 motor to assess whether the motor was faulty.
- Likely cause
- The discussion suggests the motor and brushes were probably not the primary fault, because the brushes were reported as not worn down and continuity was present across the expected motor circuits. The most strongly supported possibilities were a connection issue at the motor plugs or a faulty control module, but the exact cause was not confirmed.
- What fixed it
- No confirmed repair was documented. The accepted advice was that if the brushes are in good condition and continuity is present through the relevant pins, the motor should at least attempt to run. After eliminating obvious faults, the recommended action was to avoid speculative replacement of the control module and have the machine checked by an engineer.
- Checks to try
- Brushes visually checked and reported to look OK
- Continuity between pin 1 and pin 6: 02.5
- Continuity between pin 2 and pin 3: 04.3
- Continuity between pin 4 and pin 5: 00.7
- Motor plug connections highlighted as a possible issue
- Parts or tools mentioned
- Motor MCA 38/64-148/ZN20
- Motor brushes
- Control module / PCB
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

If the brushes are not worn right down, and are nice and shiny plus you get a reading between them through the appropriate pins they should be ok. If you get continuity between the other pins then it implies the motor should run or at least attempt to run. If it doesn't then other problems such as connection issues on the motor plugs could be to blame. Also the control module may be faulty. I never advise anyone to speculatively replace control modules or pcbs though. You get no possibility of returning them, they can be expensive, and are the most misdiagnosed parts on washing machines.
If you've eliminated anything obvious I would advise getting an engineer in rather than speculatively swapping parts.
