Default Bit of a long shot ...

Don't suppose anyone has got a 'retired' Indesit IDCA 735 condenser tumble
dryer sitting in the garage, or any mates in the washing machine / tumble
dryer repair trade that might have either intimate knowledge of this model,
or service info - specifically a wiring diagram. I believe there is also an
equivalent Creda and Hotpoint model.

Basically, I've done a front and back bearing rebuild and belt job on it.
It's all basically back together, but I have a wire left over, and I'm
buggered if I can see where it is from. I don't even remember taking it off.
It comes from the controller board, tag J11-1. This is at the bottom right,
immediately next to a thick mains earth wire which is on J11-2. The wire
that I'm having trouble finding a home for is thin black, with a small
un-insulated spade tag on the end. It heads in the general direction of the
front of the machine, but all the stuff like door interlock switch and
thermal cut out are connected. I thought at one point that it might be an
earth to somewhere as its tag on the controller PCB is right next to one
that actually is earth, but no continuity between the two. I'm wondering
whether there is a high value resistor between this wire and earth, and it
is some kind of static leak from the rotating drum somewhere. I've had the
unit powered, and it all seems to work as far as I can tell, so it's
obviously not something that is important to fundamental operation, but I'm
reluctant to return it to my daughter as being "all fixed now" without at
least knowing what the wire is, even if it would be impossible to get it
back on now it's all back together ...

Anyone help ? d:-\

Isn't there a spare connector somewhere waiting for this spade? - if not,
you may have attached something else to the connector this black one should
have gone to, which begs further questions.....

Well, I'm sure there *is* a spare connector waiting for it. If I knew where
it was, I wouldn't be asking ... I have years and years of experience of
doing this sort of stuff. I repair electronic equipment to component level
for a living. I'm well aware of how jobs like this work. When you can't find
where wire goes, it's usual to look carefully at any bends, and how it
'hangs'. This usually gives a clue as to where it goes. In this case, the
only thing that this reveals, is that it heads towards the front. If you
have any experience of doing tumble dryer bearing jobs, you will know that
in order to do the front felt bearing, the drum has to come right out, and
most of the front panel / door assembly needs to come off. As you undo the
last screw, all rigidity disappears like a magic trick, and you are left
with several floppy bits of metal in your arms. I'm guessing that the wire
came off its connector at round about this point, without me noticing it.

So wherever it goes is probably now hidden behind the drum or front panel
somewhere, and unless it is absolutely necessary, I'm sure as hell not
taking all that apart again. There are no similar single tag wires that have
been taken off, so it is not a case of a wire having been put on the wrong
place ...

I cant help as anything much beyond a 3 pin plug is a puzzle for me.
What I have done for a few years now when disassembling anything, I take
loads of digi pics in case of incidents like this. It has saved my ass a
couple of times. I dont bother to download them unless required.

Yes, I too do this, but in this case, I rather suspect that it wouldn't have
helped, as wherever this goes is hidden from view, somewhere ... :-)

Service manual (for the IDCA735IT if it's different) has J11 1 as
green/yellow ground and J11 2 as a black wire to the "drum sensing strip"

If that's any help...

Wahey! You absolute little cracker you !! I searched everywhere for a copy
of this manual. Never even considered Elektrotanya, and I use them for
manuals at least twice every single week. I guess that's because whenever
you Google for a manual, and ET have got it, they are always top or second
on the list, and in this case, they never showed up at all. I have found the
apparent location of this sensor strip on the exploded view, and it looks
like it's part of the plastic lump that the drum front sits in. When it's
good and light tomorrow, I'll see if I can see a connector tag for the wire
to go on. If it is some kind of strip that the front edge of the drum is
running on, then I'm willing to bet that it is for static discharging, and
the name has got lost in the translation from the Italian a bit.

Seriously, thank you thank you ! If you ever come to Wellingborough, I owe
you a burger from our diner ! :-)

Inclined to agree with you, but am reminded of how our current one
works, in that it has a similar sensor that it somehow uses as a
"humidity" sensor (as it's referred to in the manual) to gauge how "dry"
the clothes are. In our case it is nothing more than a short piece of
polished stainless so quite how it works I don't know. Maybe it's
capacitive, or RF damping or something

The one we had before used the difference in temperature between a pair
of NTCs to perform the same function, although the current one does seem
to be better at it...

Looks like the location of this connection will be behind the control board
somewhere, This comes out easily with two screws through the machine's front
panel, so I'll whip it off tomorrow and get a good look behind.
Interestingly, the board was removed from the front as part of the job, so
maybe as I withdrew the board, that wire pulled off its tag, and that's why
I don't remember taking it off ...
