Hoover WMH168D error code E08

I posted this elsewhere by mistake, I have a Hoover Optima which had an E08 fault, the forums suggested a Tachometer issue. I fixed the fault it was just the motor brushes. i made a video including testing the tacho and changing the brushes that cost me a tenner. easy fix hi I had this fault google said it was tachometer fault. the e08 fault on my hoover optima was not the tachometer, i checked it, but the fix was very easy, the motor brushes were worn out and i changed them for 10 quid, I made a video of it its on you tube http://www.youtube.com/watch?v=xYn-f78GB4U if its any use.

E08 = Tacho fault

The tacho coil is on the motor and is fitted at the opposite end of the drive belt where the carbon brushes are. This error says something is wrong regarding the tacho coil but it doesn't specify exactly what. Possibilities are varied so unless you know what you are doing, and unless you can see something obvious like the coil has come away from the motor or the motor or drum has seized up it is probably better to call in a professional.

Resistance readings for tacho coils are usually quite high, so if you don't have a sensitive enough meter it could appear to be open circuit when in fact it's reading over 150 Ohms or more and may be ok.

In conjunction with a magnet fitted on the end of the armature shaft each time the motor does a revolution it can be counted by the software or pcb through the tacho coil. This information is used to judge and control the speed of the motor at all times.

If the coil is open circuit the washing machine would lose al control of the motor and in the past the motor would often spin uncontrollable causing damage to the washing machine. These days if an open circuit or missing tacho coil (they can fall off the motor) is detected the machine will stop working and report an error code.
