Hoover WS130 washer/dryer – no drum speed control?

Hi,

sorry this is gonna be a bit of a ramble – but bear with me :rolls:

I’ve an 8 year old Hoover WS130-001. I wouldn’t say it’s had a particularly hard life … however over a period of time with washes on low temp it can get a bit whiffy washing on 40 degree washes … so as usual I put it on the hottest temp with ariel tablets. However this didn’t cure the smell completely so I put some bleach in the relevant compartment and carried out the maintenance wash again.

After which I thought bingo … off we go. I put a load in as usual and left it to run. When I unloaded the clothes I thought they were unusually damp.

I put the machine on a spin cycle, what happens is that the drum seems to spin at probably the slow spin speed for about two seconds, then stops for about two seconds – this repeats three times, after which it doesn’t spin again at all for the remainder of the cycle. I’ve tried all the other programs (including drying) with the same result.

… I’m assuming the problem is just coincidence …

If the machine is power cycled, the burst of three spins then nothing is repeated.

I’ve had the motor out – plenty of life in the brushes, the tacho generator coil read about 150 ohm resistance. If the motor is spun by hand, an AC voltage is generated and seen on a multimeter, proportional to spin speed – so I guess that part is working … Checked the tacho generator connections on the wiring loom – no problems there.

Removed the programmer / speed controller – there’s a 5.6k ohm resistor, the connections to which looked a bit suspect – so I remade them – other than that no obvious problems on the circuit board.

I reconnected it all again – same result. Measuring the tacho generator output at the input to the controller shows a peak of about 8 or 9VAC, so that further confirms that seems to be OK (unless the voltage should be higher?)

So … I’m leaning towards the combined programmer/controller … any other ideas? How much is a replacement?

Thanks 😉
