For the archive, this advice covers top loader
Hoover 820, 830, 835, and 920 as made in Oz from about 1975 onwards.
I got the machine fixed in 30 minutes once I had the schematic as
reluctantly supplied by the
local main Canberra supplier of parts to the appliance fix-it trades.
They sell to the public, so the public should be able to get a copy
of the schematic or risk making a mistake or two like me.
I am always humbled by the shit that happens in this world,
and especially when I have caused some of it to happen,
although unintentionally.
I found that of about 20 wires that plug on the back of the timer
control unit
There were 4 that were misplaced, and its a wonder the machine worked at
all.
I thought only one wire was wrong.
So during the 4 previous occasions when I replaced the controller wire
by wire without a schematic
I probably got a wire or two wrong, and finally one came off a lug and
the machine stopped last week.
Checking with the schematic is very easy since the wiring harness has
all dual colour striped wire,
and all you have to do is check the wire colour against the pin out
number printed on the controller.
Anyone could do it with a minimum of skill, but the lug connections tend
to get
loose as grippers loose tension, so squeeze a bit with long nose pliers
while they are off the lugs,
then clip them back on tight, and they'll maybe OK for the next 30 years
of washing.
Of course Hoover would have saved lots of bothers if they'd had
all the wires brought to the controller in ONE plug with many
connections,
or maybe TWO plugs, then there'd be no way wires could be misplaced,
but they must have thought it too expensive to produce multipin plugs
and a controller with convenient pin out positions which would all work
and be safe with
240V mains and considerable currents.
And BTW, for umbilical cables between PSUs and amplifiers,
I tried to find multi wired cable which allowed opposite phases of
240Vrms applied to each
adjacent pair of wires at up to 4 amps.
Another local electrical supplier found a source for such cable,
but he couldn't find a cheap simple 12 to 18 plug and chassis socket.
So I will stick to tube type octal plugs and sockets.
Multi pin plugs used for car trailers are OK except that it does not
look
OK for highish DC or AC voltages in tube amps.
7 pin is the highest number I saw.
In my 845 amps I have 13 connections, so 16 pins of 2 x octal plugs will
do,
and I will leave a pin each side of the +750V unconnected.
