    Hello,

    I have a Beko WM1520W.
    2 days ago, I started a load, machine filled with water and a couple of seconds into the first drum rotation there was an almighty bang – like something hard being jammed between 2 immovable objects and then breaking free – and the rotation stopped.

    With trepidation, I cancelled the wash and restarted it. Machine filled with water and drum started to rotate. No noise but rotation stopped after 1 turn. I drained machine (via filter) and removed clothes.

    On inspecting the inside of the drum I found a small dent about half way back.

    Now machine will operate on washes, rinse, drain and spin but where the drum should turn, it only turns approx once after each click of the timer. It changes rotation direction (as it should) on wash, it goes faster (as it should) on spin – but always only 1 turn. It’s as if the power to the motor is cut out after 1 spin but returns briefly after each timer click. If left to run, machine eventually puts itself on pause.

    Nothing I’ve found on your forum or elsewhere matches this problem so I hope someone can help. Below are the things I’ve checked/tried.

    Many thanks!

    Checked filter – clear except for a small label and a couple of small pieces of plastic
    Removed filter, drain hose and gater to drum – all clear so replaced
    Hand turn drum – moves freely without any noise
    Checked fault code – left and right hand lights come on which I think means failure to drain… but it drains fine – after a drain, removal of filter gives only a small trickle of water (Code check method – turn off, put on 90 cycle, hold start button and turn on, wait till start light flashes and release start button)
    Reset code then tried a wash immediately and symptoms still there. Recheck of fault code gives same code as before (Reset method: Code check then.. tried both just pressing start button and turning to spin then pressing start button before turning off)
    Checked weights – before securely attached
    Checked springs – both attached
    Checked suspension – both attached and look equal. Pressed down on drum which returns to proper position after release
    Checked movement of inner drum in relation to tub – can’t feel any
    Checked outer tub – intact. Appears undamaged and there’s no leaks

    Re: Strange rotation problem

    could be a motor tacho fault – either broken magnet or open circuit coil

    Hi Martin114,

    Oh dear. Neither of those sound like they’d be easy or worth fixing.

    Thanks very much for your input.

    That wouldn’t necessarily account though for the “almighty bang” and the dent in the drum. 🙁

    Broken spider arm maybe gents?

    Thanks for your suggestion, Muv

    If the spider suddenly cracked in two that would fit the bang I heard and if a small piece of metal was flung off, ricocheted and hit the drum it could explain the dent. A broken spider arm could also explain the stopping if the imbalance it causes is great enough to make the ‘out of balance’ protection to kick in – even on a wash cycle.

    However, wouldn’t there also be noise/bangs each time the drum rotated and wouldn’t there be movement I could feel between the inner and outer drums? There are neither of those…

    I feel loathe to give up on the machine as it isn’t even 5 years old but if it’s the spider, it looks like it’s only available for this model as part of a “welded tub assembly” for £100!

    Up to 5 years is a good run for most Beko machines especially if it’s in use daily in which case you can double that to almost ’10 washing machine years’. That aside, I’m thinking whatever jammed and dented the drum (coin? nail? Bra wire?) may also have created problems to the main PCB? Can’t rule out the motor having suffered though more likely the belt would be the first to break IF the drum momentarily jammed at that time.

    It’s all a bit ‘what if’ I guess. One thing’s for sure, it’s gonna be expensive. 🙁

    Thanks for your advice, Martin.
    Even though it gets only 3-4 loads a week it sounds like I’ve probably had my money’s worth from it. I was going on my previous machine which was second hand when I bought it and lasted me 10 years before it’s first fault and I kept it going another couple of years by repairing.

    I bought the Beko mainly for its small capacity – 5kg (to prevent running out of clean underwear before I have a full load of one type to wash) – and lack of ‘bells and whistles’ – I only ever use 3 of the settings anyway.

    Searching online for a new machine, information about how many cycles a machine is built for never seems to be listed in the specs. Or am I missing something?

    Seeing as my very cheap Beko lasted 5 years, I’m wondering if it’s worth forking out 4 times as much for, say, a Miele that’s bigger and more complicated than is useful for me. I can’t see any machine lasting over 20 years or repair parts being available beyond 10 years these days.
    Are there any simple quality machines for very small households out there?
    I don’t like it but it seems the most cost efficient option (for me but not the environment) is buy cheap, replace often…
