Hello to all.
Mike
Thanks again for the great diagrams.
Duh! (whacks head) Now I see what "3 Comp" means on the 951E diagram. Three compartments!
The 951E diagram is also interesting in that it shows alternative door interlocks. My 455 has the three wire interlock, but two of the wires are different colours to the 951E diagram.
On the grid guide, I am surprised to see that some washers changed to the AC motor (and AC module presumably) during their model lives. Is it confusing to ascertain whether the washer being worked on is DC or AC, or did the AC models always have the Crouzet timer? I suppose this would really only be an issue if the motor or module needed to be replaced.
I note from the grid guide that the A3090 has only 10 programs (Bio Prewash & Whites Special are missing), though with a 951 timer. As Whites Special is really just Whites with the spin-hold switch on hold, I wonder did Hoover just not mark the Bio Prewash program on the knob, or were there other changes to the timer. On the 951 circuit diagram, the A3090 doesn't appear to have any wiring differences to the other models.
It would be interesting to see an A3090 control knob up close to see if there is a gap where Bio Prewash would normally be, and if this is so, to be able to check if this unmarked position can be selected. If this hidden position can be selected, it seems to me that this model having only 10 programs was done for marketing reasons, seeing this was the bottom of the range model at that time.

An interesting idea. Presumably the active wire would be just taped back, and the other two wires would be joined to bypass the three-wire interlock. I am forever grateful that my washer has a mechanical interlock, as these days I'd be stupid enough to open the door without thinking when the machine's on hold.
The washer's still going well. I'm amazed at how quickly it heats the water now. I guess removing all the years of scale from the element might have something to do with that.
Cheers and thanks.
John
