-Currently broken. We'd like to fix it.
+Currently working.
-[[user:mentar|Mentar]] had a look at it. What we know:
-* It switches on but won't spin
-* Motor is ok
-* Problem is with the electronics
-* Could be to do with the locking mechanism (machine thinks it's not locked when it is and hence won't start)
-* It's definitely not that, it went BANG! and blew the fuse

-This appears to be the service manual for it:

 Connector J12 (supplying mains power to the motor drive) is badly damaged and I have removed it. This is a three way Panduit brand IDT connector. I think it is an ITW Pancon brand MAS-CON 3.96mm connector (eg. http://uk.farnell.com/itw-pancon/ce156f22-3-d/wire-board-conn-female-3pos-3-96mm/dp/1418234).
-The symptoms I've seen are consistent with the motor drive not getting any power (due to the damaged connector) or being otherwise broken (and hence damaging the connector).
-I suggest:
-* Step 1: replace J12, either with the same type (if we can find a source) or with another 3.96mm connector of suitable specification.
-* Step 2: carefully test the motor drive circuitry.
-* Step 3: if the motor drive circuitry appears to work test the whole centrifuge.
