Tip & How-To about Washing Machines

Error Code & in washing machines..

Error 7 means - “Motor jammed / Drum shaft jammed / Tacho generator fault”

Motor jammed

The first possible fault could be if the motor is trying to turn but the motor is physically jammed. This is likely to be rare. It’s easily tested by opening the door on the washing machine and spinning the drum by hand. If it moves normally and freely it’s clearly not jammed and this is not the fault.

If it is jammed or very stiff then making sure the machine is disconnected from the mains supply you can just take off the drive belt. You can then see if the motor is jammed or not because the shaft where the belt fits wouldn’t be able to be turned by hand.

Drum shaft jammed

This would cause the exact same problem in that the motor is trying to turn but because the drum was jammed it couldn’t. Again, easily tested by turning the drum by hand – if it’s free then it isn’t the fault. If it’s jammed or very stiff, removing the belt will let you determine whether it’s the motor or the drum that’s jammed.

Tacho generator fault

The way a washing machine detects the speed of the motor is via the tacho coil which is the last potential fault listed.

The tacho coil is on the outside of the motor attached to the end opposite the drive belt with 2 thin wires running from it. It’s a small coil that surrounds the shaft of the main armature where a small round magnet is attached. As the armature turns the magnet on the end of the shaft turns inside the coil. It’s then easy for the pcb to count each revolution of the small magnet and work out how many revolutions per minute it is turning.

What is error code 7 on hoover wmh168d?


Louise, E07 means "Motor fault. check motor, tacho and associated wiring, check drum has not jammed" Presuming you can spin the drum by hand, I'd put my money on the carbon brushes in the motor being worn out and needing replacement

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.

ariston error code f02


Hi.

Try first disconnecting the power cord or tripping the circuit breaker for five minutes. This will reset the control board in case the error had been only a temporary fault.


If disconnecting and connecting back power does not clear the error, then F02 means Motor jammed or tacho detached.
This means that the main electronic control does not detects any signal from the tacho coil/magnet device attached at one end of the motor, and detecting motor speed.

This basically means that either there is a wiring problem, a motor problem (often jammed), or that the tachogenerator is not working.
Testing is done accessing and testing motor, testing tacho coil, and testing wiring harness to control board.

Try first disconnecting power to reset the machine, if that does not work, call Ariston service at the number listed on the owners manual.

Regards.

hotpoint ultima wt721 error code fo2 showing! will not work properly!


Error code F02 means the motor has jammed, and or the tacho is loose or broken. .Check the motor hasn't jammed up somehow, or that the small tacho coil on the end of the motor hasn't dropped off (tip the machine back and it's in between the brushes - it should be held in place with a clip. If it's hanging loose it's the fault)

This fault code basically means the PCB cannot detect any impulses from the tacho coil on the motor, so the main implication is that the motor is just not running. However, because other fault codes cover most of the other motor faults, the PCB thinks the motor may be physically jammed. That is, as far as the PCB is concerned, it is supplying the motor with power, but it can't detect the motor is running. This fault is not caused by worn carbon brushes because on these washing machines, an open circuit on the motor causes the washing machine to do nothing at all. It would not fill, or empty (as well as the motor wouldn't run) although the indicator lights would work.

What does F-02 mean on the hotpoint aquarius WF 720 model. Half way through the cycle this came up on the display and stopped working.


F02 - Motor jammed or tacho detached. check motor is free to turn and circular magnet at other end of shaft from belt has not broken/fallen off(tacho generator).
