525-520 1
Hoover 525 (A3658) and 520 (A3656)
Why these model numbers numerically precede the 495/490 model numbers is unknown.
The “Zodiac 12” name was gone - these were called “Electra”.
The control panel and bezel were taller than before, and the detergent drawer returned, with a conditioner dispenser now included.
There were six buttons in a row on the control panel. From right to left they were:
Power - power on/off,
Heater - heater on/off (this was blanked off on the 520),
C/Guard (Crease Guard) ‘spin – hold’ control,
Cold - cold water inlet,
Warm – mixed hot/cold water inlet, and
Hot - hot water inlet.
The latter three controlled which inlet solenoids opened on initial fill.
The control knob was nearly flush with the control panel and was easily used “with wet or impaired hands with arthritis or similar problems”.
The heater switch allowed the 525 to operate on any cycle without heating action (basically as a 520).
The power and Crease Guard switches had neon indicators above them.
The timer was new and more in line with the Hoover top loaders. Approximately one half of the dial was used for normal washes, and the other half for gentle washes. Thus there were two off locations.
The tumble action was again different for these models. Normal action was now tumble in one direction for 15 seconds, stationary for 5 seconds, then 15 seconds tumbling in the opposite direction, and stationary for 5 seconds. If this sounds familiar, it’s exactly the same action as the 3236H and 455 on their normal tumble action. Gentle action was now 3.5 seconds of tumbling and 6 seconds of pause, then a further 3.5 seconds of tumbling and 6 seconds of pause, in one direction, then repeated in the opposite direction.
The motor was basically the 2/16 pole induction motor introduced on the 485/480, but with the addition of a tachometer and electronic speed control module, similar to the previous brush type motor. These additions allowed the machine to offer different drum speeds for tumble and distribute, and 800rpm spin speed for the normal cycles, and 500rpm spin speed for gentle cycles.
Drum speed for tumbling was now 60 rpm. Distribute speed commenced at 60 rpm, which was then raised to 100rpm electronically.
The door was now plastic, though it still used the same glass going back to the 3236H. There was a new door release lever.
The water inlet solenoids were again the familiar type with screw on hose connections.
The drum bearings were the same as previous models, but a lip type oil seal was introduced, replacing the previous carbon face seal. The seal lip contacted the shaft of the spider.
A single, dual temperature thermostat was used on the 525 which contacted the water like the previous UK models. It was located at the bottom of the drum rear plate.
The colours were white for the cabinet, with a white, grey, and blue control panel. This colour scheme was also used on the top loaders and dryers at the time.
Contemporary Hoover dryers were also included in the brochure.
My thoughts.
I am quite biased when it comes to these models as my parents bought a 525 with its matching dryer in 1991, on my recommendation naturally. To me, they were the high point of Australian Hoover front loaders. They were refined and quiet, and the control panel and colours were very attractive, and are still so even now. I replaced the drum bearings and spider on their machine in the early 2000s, and took photos of course. After my 455, I could easily own one of these.
Good points:
As above, very refined and quiet, and attractive colours.
The reintroduction of the detergent dispenser, now with conditioner as well.
The heater on the 525 could be switched on and off as required.
Fast and gentle spin speeds.
Reintroduction of screw on hose fittings.
Bad points
The door latch was a problem on these as the plastic lever snapped easily. Later replacement levers were shorter to reduce the mechanical advantage on the plastic.
This brochure is A4 size and dated April 1990.
