|Hoover WS130 washer/dryer sometimes doesn't spin - any ideas?|
Sometimes it works fine, but with increasing frequency the machine will not spin when it reaches the final spin cycle, neither fast nor slow spin. The pump works but the drum either doesn't turn at all or turns slowly and doesn't get past the distribution speed. At this stage, if I take the wet clothes out and set it to spin when empty then still it won't (so not due to an unbalanced load). I have replaced the motor brushes and have checked that the pressure pipe is not blocked (I can gently blow down it and hear two pressure switch clicks). Strangely, if I leave the machine overnight and set it to spin in the morning it works fine for a while, generally until the spin cycle at the end of the next load. When it is behaving, I can usually get it to go wrong by running the dryer for 20 minutes and then setting it to spin - it doesn't, but a few hours later it does. This may be a red herring, but It seems to behave when the motor is cold. Whenever it misbehaves the motor is warm (never hot), but it doesn't always misbehave. Is there a thermal cutout for the motor? Is it likely to be the motor or am I missing something more obvious? When it is refusing to spin, if I power off and on the drum does seem to get a small kick from the motor before settling into inaction. Sometimes it will start to spin but as it tries to increase spin speed it then stops abruptly and begins again (even when empty). Rarely (1 wash in 4 maybe) it works properly. I suspect the motor, but am puzzled as in all other respects it always works normally, turning the drum to wash or dry - just not reliably to spin. Thank you for reading all this. Any ideas gratefully received.
