A friend wanted to use an ex-dishwasher pump for a d-i-y application but was
puzzled as to how to wire it up so he asked me and I'm baffled too.
Perhaps someone here can help.

The pump is of the induction motor type, having a 4 uf capacitor and three
connection wires, red and blue of normal size from the capacitor and a thin
white one entering the windings directly.
The device may be seen he

The pump is thought to be from a Candy Dishwasher, model D7610 or D820
range.

The red and blue wires on the motor side of the capacitor are shown
connected as found. Presumably the red and blue are the supply and the
white is for start and direction.

With red and blue wires were connected across the mains and the motor hums
but does not run. If the armature is spun in this condition it continues to
run in whatever direction it is turned.

If the white wire is connected to the supply the motor again hums but does
not start or run and if spun -difficult- it immediatly stops.

Please advise.

What SHOULD happen is that the red and blue wire in the motor go
directly to the mains, and the mains should go to the white wire VIA the
capacitor.

I can't figure out how that can be achieved with what you have there.

Hmm the one sitting in front of me here, also looks odd.looks like it
also has red and blue to go to the capacitor....possibly the power
should go into the white and blue, with the motor connected as you show it.

This is how I thought it was supposed to work
