Good afternoon,
 
Does anyone know who might be able to supply the user manual for the above equipment which I recently found in a lot of things we bought in around 1994 It says on the back that it is called a DC-X994 and it says it was made in Singapore, but I do have the Sanyo advert in UK in which it looks like a salesman selected it for me and I actually purchased it in the United Arab Emirates.
 
At this time I was often in all three places so anything is possible.
 
Does anyone know when Sanyo was taken over and by whom. If anyone has one of these handbooks, I would be glad to pay for it to be copied It ended up in a container. That is where I have recently found it and I do not think it was ever used, it looks brand new. It was a fairly popular item.
 
Any ideas? Thanks George.

Thanks for the link Mike, however it did not react to either of the two product codes. I have the 1994 25th anniversary of Sanyo, hand out issued in UK and this Wi Fi system is featured, but on all the handbook sites this code SYS 994 and the actual one on the back of the unit is DC-X994 and the fact that it was made in Singapore. It really looks like something I could put to good use if I had the instructions and it is like new, having been stored in a 20 ft. container for the last 16 years. The container is crammed with the result of three house fulls of mostly furniture and will take ages to unpack. Regards George.

What exactly is a "Hi Fi System"?
 
Is this a stereo receiver for the home or some kind of ghetto boombox?
 
If it's the latter, I'd give up now.
 
Most of those things from the 80's and early 90's were probably built from
boards/modules cranked out by chinese or korean white box companies and just
assembled by companies like Sanyo, if they had anything to do with it in the
first place.
 
Plus what is so complicated with it you need the user manual?
 
On/off, selector knob or switch for the input, after that, volume and tone
to taste. What else do you need to know?

All LG ideas are bad, sort of like their products.

You already said the pump failed. What's the question here?

As with many other products, modern residential washers need maintenance on a fairly regular basis. We have a 15 year old LG front-loader at our summer house, we just replaced our 12 year old (purchased reconditioned) LG at our main house. We replaced it because the fill valve and the drain valve failed together, and the parts and time involved for a machine that heavily used (7+ loads per week) mitigated towards a new unit that was more efficient, and has a few more features.
 
At the beginning of each quarter at home, we clean the drain sump. Takes ten (10) minutes at the outside. And we have pulled all sorts of *stuff* out of it. At the summer house, we do it at the end of each season as part of the winterizing process. That one gets, perhaps, one load per week.
 
Unlike the bad old days, when a washer used 40 gallons of water, and lasted very nearly forever if not seriously abused, a modern washer will use maybe 5 gallons of water, and needs a bit of care and feeding, or it will not last very long at all. That is not the fault of the device, but of the user not understanding their obligations towards achieve that efficiency.
 
As John Muir wrote about VWs - "Come to kindly terms with your ass, for it bears you.". Come to terms with your machine and it will treat you well.

> You already said the pump failed. What's the question here?
 
'cos everyone is trying to convince me that buzzing/grinding is a sign that the pump is OK but blocked, - the problem might be a blockage behind the pump which would stay there after pump replacement. Also, there is a video out there which says that a failed pump has an impeller which moves freely. And that there being pressure between quadrants as you turn the impeller is a sign that the pump is actually OK.
 
But YOUR point is more valid. If the pump starts to buzz/grind for anything more than a few seconds and water stops being pumped through, the game is up! Especially if there really isnt much in the filter area and I can move the impeller between quadrants, indicating that no BLOCKAGE is stopping the impeller from moving.

An LG washer pump is about $25. The entire assembly may be had for $60 or less. Takes about an hour to replace - ask me how I know that. As compared to +/- $700 for a new machine, or a service-call of about $150 + parts. No special tools required, and at least half-a-dozen YouTube tutorials on how-to.
 
These pumps fail from:
 
a) Pump impeller blockage - takes a lot to get to that, but it is possible if the drain sump is never cleaned.
b) Running too much suction - far more common. Clean the sump! Regularly.
c) Age - these are cheap little things. And very easily replaced.
 
If you were to direct all that energy expressed as anger at addressing the actual cause, then fixing the cause, your life would be better.

Any anger only arises as a result of having to spend so much time and money on a machine which is so badly designed that it WILL fail again within 2-3 years and need an extraordinary amount of work cleaning it out!
 
I have seen the videos and the work for this pump looks easy but is VERY extended. Also, there is a metal ring around the door seal which looks like a real pig to re-fit! Even for me, where i get a real rush out of taking intricate things which dont work apart and fixing them!
"pfjw@aol.com" <peterwieck33@gmail.com>: Jun 15 07:09AM -0700

I keep a pair of hollow-nose slip-joint pliers that manages that ring very nicely (among many other uses). I have no idea of the technical name of that plier, but it does the trick.
 
As I previously noted, took me about an hour from start-to-finish. But I had good light and lots of room.
 
The part that gripes me about the older LG machines is that they rust, badly. After about 2015 or so, they seem to have fixed that. And the reconditioned unit that we replaced a bit ago cost us about $0.14 per load (machine only) or so, so it owed us nothing at all. Were it not for the rust, I probably would have done the necessary repairs....

What is the reliability difference, if any between the classic
transfomer/diode/capacitors and the fancy inverter ovens?

The Inverter model reliably makes a louder sound on expiry?
 
I'd bet the fancy Inverter design is to get the price down, cost of
copper and weight etc. The chief reason for a SMPS.

It is all in accordance with what you want.
 
An "inverter" microwave modulates the output of the magnetron directly. So, 50% setting means the magnetron is putting out 50% of its full capacity, but all of the time. With a conventional microwave, that is achieved by running the magnetron in duty/rest cycles. 100% for 50% of the time 0% for 50% of the time. Inverter-based microwaves become far more flexible and therefore far more useful.
 
Re Reliability: Our present Panasonic (inverter) is about 6 years old and gets moderate use. It replaced a 16 year old multi-voltage BEAC we purchased in Saudi, that is now still in minimal use by a neighbor in his garage workshop. We keep our devices clean, make sure they get enough air circulation, and, heaven forfend, even clean the vents regularly!
 
Basic care-and-feeding is becoming a lost art.
