    Hi guys,

    Hope you can help me with a problem with my Hotpoint WD420 (a couple of years old).

    As I am an Aussie (insert joke about being a thief / shipped from England etc), I don’t have anyone that can help me with with support.

    Basically I set my machine going and came back 4 hours later to find it stuck in the wash cycle…..

    I tried a few things (power button etc) with no luck.

    eventually I turned it off at the wall and since then it is dead!

    On power up (at the wall) the power, dry and the top four lights flash once and then nothing!

    Any help / advice would be greatly appreciated!

    best regards,

    James from down under

    Hi James,
    The notoriously unreliable electronic board is the most likely culprit here. No heat on wash doesn’t always bring up an error code, but the fact that the board will not now power up is a bad sign.

    The machine has a 5 year parts warranty – pcbs are expensive, so this may be your most economical route to a repair.

    Power off if you intend to have a look inside.

    We like Ozzies really, BTW – they even have their own forum way down at the bottom!

    Thanks for the reply Penguin!

    Anyone out their know how I can get my hands on an electronics board for my machine under warranty in Australia?

    I am an electronics engineer so will probably have a look at a component level repair in the first instance…..

    I am thinking crystal / resonator to the main micro as the pcb isn’t shock mounted and gets a lot of vibration. Also fits with the fault I experienced (ie machine stopped mid program).

    Best,

    James

    Ah…… Didn’t realise that you were posting from Oz. I know that you’ve got Ariston down there (same company, different plastic), so it might be worth approaching them for help?

    If you’re into the electronics side of things, dodgy/oxidised edge connectors, sticking/broken relays, burnt tracks, exploding triacs are all quite normal fare with these.

    Good luck,

    I have had a similar problem reported to me just today (jimbob42 – do you work with Colin at Deakin uni? It could be the same one)

    Generally if it was bought in AU, then contact the seller for info as to where to get parts. A company called DEC quite often import small quantities of appliances and hold over a few for spares. Others may do similar. I have never seen Hotpoint appliances in any quantity in Au stores.

    I doubt that Arisit (the AU importer of Ariston & Indesit) could help as they are generally unable to supply a replacement PCB for any machine without both model & serial number.

    Certainly am the same guy!

    What a small world hey 😉

    Yeah, have chased up a service rep in Melbourne that can supply the PCB at a reasonable cost. Would still love to figure out what the fault was / is though.

    I am pretty confident it is the crystal on the controller but the part number makes no sense…..

    6 Pin oscillator marked “491 E” if anyone is familiar!

    I dropped a 4Mhz Resonator in with no success.

    Might get the CRO onto the new board if it fixes the problem and report back, would be a cheap fix for the other guys out there with similar problems.

    Best,

    James

    I never knew these boards were ‘crystal controlled?’ Using oscillators to determine a resonant frequency? Tuned circuits, surely not these days? 😕

    We have a better fix in most cases, :rolls: 😉 😆

    An option much favoured by trade member Goatboy.

    Hi Martin,

    All new devices have a microcontroller on board that ‘step’ through a program at a certain frequency. This frequency is determined via the crystal.

    Iadom, you wouldn’t believe how often I have wanted to do that!
