Hoover 455 (A3072) Washer Overhaul Pt 3

[crouzet951]

Hi Mike

Many thanks for the scanned circuit diagram. I thought that might be the case for the neon.

It's interesting in the circuit diagram that it shows there's a third water inlet valve for fabric conditioner. The valve is connected to terminal 12C, which does not exist on my timer. The A3058 shown in the thread at the link definitely has no third inlet valve, so perhaps the diagram is for a later revision of this model, hence the 'E' suffix in Crouzet 951E.

Thanks also for the scanned brochure. Oh how I'd love an A3062 Keymatic. Sigh!

Hi Gizmo

You are probably correct that the dryer was made by Fisher & Paykel. Just today I was checking out the laundry appliances at David Jones (an upmarket Australian department store), and there was a Fisher & Paykel dryer that was remarkably like the Hoover 195 from all those years ago. An image is attached. I wonder if Hoover Aus licensed the F&P design as the basis of their later Aus made Apollo dryers.

Cheers to all
John

Crouzet Timer 951

Hi John, yes the 951 covers the 3006 and previous models, the 951E as you say does have the 3rd valve for fabric conditioner dispensing, the E being Electronic..

Heres the Crouzet 951 sheet..

Hoover Timers Reference Sheet

Hers the grid guide, you can also identify the two and three compartment dispensers, hope this helps...

Poxy Door Interlocks

hmm just link out the two black wires on the motor module and the suppressor and hey presto no door delay on finishing, yahhhhhhhhhhh ;-)

Ps you don't have to do this but I hate them

Good luck

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.

Gary

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

Very impressive !

Just read your posts on your 455 refurb from a couple of years ago - what a fantastic job you've done.

Is it still going strong ?

I've just started on a Hoover Logic A3670 - it's my first big overhaul - your posts have given me lots of inspiration and motivation, and some great tips.

Would love to hear how the 455 is doing, being a fan of Hoover Washing Machines and Oz !

Mike.

Question. When you pull off the leads to the timer, how do you know where to reconnect them? How do you go about changing a timer in a UK or EU based machine?

Photos.

Hi when changing a timer take lots of photos from all angles. And draw a simple diagram of needed. Some times the cables are on blocks which is easier as they often only fit one way. Some are lord of wires. Some don’t need to come off until after the timer is or I’ve bridging wires so leave them until the timers out and on a bench

Good luck
