Spins Very Fast For A Few Seconds 3 Times With A Minute Or So Gap In Between, Empties And Then Stops

[typhoon4665]

The machine starts, fills with water then spins very fast for a few seconds 3 times with a minute or so gap in between, empties and then stops. The display says END and the timer doesn't change. Any advice would be appreciated. I have checked all accessible connections and components and can't find anything obvious.

It sounds like it's lost control of the motor. It's trying to get the motor to wash but it's shooting into a spin and it's detecting this and aborting the programme. A broken tacho magnet on the motor under the motor plug housing could account for it but potentially other things could too.

Thanks Andy, Tacho magnet ? does that work like ABS on a car ? would I be able to purchase one or would I have to buy a new motor ?

There's an explanation of how the machine controls motor speeds in this article under the section "Tacho generator fault" http://www.whitegoodshelp.co.uk/hoover-nextra-error-code-7/

Thank you, it was very helpful, I will strip it down and check the tacho magnet is secure and check the resistance of the circuit.

I have checked the motor, the bushes are fine and I cleaned the commutator.The Tacho magnet is secure in its housing and I have checked all cable connections and found no obvious faults.

Does anybody have any other suggestions please.

If it isn't the motor you have to suspect the PCB but I wouldn't recommend buying one and fitting it in case it's a weird other fault or something's blown something inside it.

Thanks Andy, I thought that might be the case. A new one it is. It wont be a Beko though !
