This is my first post on this forum. I suspect that it will be of interest only to old-timers!
We bought this 9901W (white with brown trim, not Polar) in 1989. It's still going strong - in fact I've done a load of washing with it this afternoon.
It has had some TLC over the years. I was very fortunate to be able to copy the 9900/9901/9920 Hotpoint service manual. The manual was lent to me from Kirkgate Washers in Leeds in the 1990s on the understanding I would return it, which I did! It has proved a very useful document to keep this machine going.
Over the years replacements have been made to drum bearings and seal, water solenoid valves, motor brushes, one drum-door seal, a new motor armature, and the vulnerable door latch interlock. I'm not complaining at all after 36 years.
A few days ago, I was concerned that it got "stuck" mid-cycle. When I washed the next load, I decided to observe the machine, with the top off, with the manual and a stopwatch to hand. It was an interesting experience! I could see that the timer indexed one notch at a time towards the end "sun" symbol, but the intervals between the impulses varied. There was no fault when I watched it. Having done two loads since with no fault, I suspect I was getting a bit over-anxious.
My question is aimed at technical gurus here, and concerns how timer impulses are timed. I can see the synchronous motor on the timer. The time intervals between timer impulses vary widely in duration. How are the timer impulses controlled? Is it done by the mysterious "Module"?
Does the synchronous motor only serve the sub-interval timer? Does the solenoid contactor on the back of the timer operate the water heater?
My intention is to keep this machine going as long as I can. I fear that, ultimately, its demise will be due to corrosion of the outer drum. If that happens, I doubt there will be a possible recovery.
If and when it does demise, the Ebac machine appeals, but it has a lot of negative reviews. It is, however, one of the few machines that allow drum bearing replacement.
I have the User Handbook from when I bought the 9901 new. If PDF copies of the 9900/9901/9920 service manual and/or user handbook are of interest, please let me know.
