Problem Hoover Nextra HNL 6146

It's the first thing I did wednesday. I know this error code. I've had this ten years ago and you told me how to repair my washer machine. I've fixed the magnet tight. Then the washer machine worked perfectly. But only once. When I tried again, it didn't work anymore. But no more error code. The machine do "vroom vroom vroom" as it wants to accelerate. Don't laugh! ;-) I don't know how to explain it. ;-)) I've verified the pump. It works perfectly. Anything is blocked inside.

The autodiagnistic runs right, but the spin at the end is short (5 sec instead of 27 sec) and the led's continue to flash.

I know my first topic is long and that my English is bad, but I've explained all what I've done in this topic. Perhaps I've done something wrong. Could you please read my first topic again. If you don't understand something I'll try to explain it more correctly!

Excuse me and thanks a lot for your patience.

Have a nice evening

If the washing machine motor is spinning too fast this is a fault between the tacho coil and the PCB. On modern washing machines it's usually caused when the tacho coil magnet has dropped off, is very loose, or is broken. If everything is okay with the tacho coil and the magnet, and you have continuity between the two tacho coil wires in the motor harness down to the PCB then the only suspect left is the PCB. However, they are too expensive to risk buying one in case for some reason it doesn't fix the fault.

Good afternoon,

Thanks a lot for your answer.

I've dismounted the tacho again and I've noticed that the two metal parts weren't in contact anymore.

Perhaps because I've pushed the tacho ring a little bit too deep in its emplacement.

I've glued these two metal parts at the plastic part with a strong glue (Have you another solution?). I don't know if it will hold on a long time!

The washermachine works again. \o/ But it does a strange sound when it's washing. It doesn't do this sound when it's spinning.

I attach two sound's files, so you can hear it.

I there something else wrong? Can I verify something else?

Thanks in advance for your answer.

Have a nice day

The first one sounds like it's not getting even power so the motor seems to be surging a bit. I can only assume it's related to the fault you've been having.

Good morning,

Is it dangerous or bad for the motor to keep my repair like this or must I replace the tacho and the magnet?

After hearing the sounds, do you think the PCB is in question as you said in a previous answer?

Or do you think there is probably another problem!?

If the motor is sparking excessively then it is definitely not good. If it isn't, then it's hard to suggest what to do. I've never heard of a fault on the tacho coil or magnet that would cause this sort of issue. If they are faulty then either the motor stops working altogether, or it spins out of control. As I said it sounds like the motor is not receiving a smooth voltage. That could be caused potentially by a component inside the PCB. But I'm not in a position to suggest that replacing an expensive PCB will definitely cure it. Apart from doublechecking all of the connections and wires on the motor plug and in the harness going down to the PCB there's not much else you could do.

You could try tentatively using the washing machine but there is a possibility that it could jump and leap about violently if the motor isn't under proper control. If you do risk it you need to be on hand to switch it off if it suddenly leaps about. If that did happen it is possible for the washing machine to sustain damage so it has to be your call.
