    Re: NEFF 8406 Cycle never completes

    As ever, really grateful for your help.

    Just a few questions, if I may, to put the task into some sort of context (I’m the sort of guy who tries to replace a tap washer and ends up burning the house down!).

    Would this be a big (i.e. time consuming) job for a competent engineer?
    And how long do you think it would take to do the job?

    Do you have any feeling as to whether the major cost of this job the price of the replacement part or the engineer’s time?

    Also, do you know what the typical lifespan is of this make/model? I appreciate it’s impossible to say for my particular unit, but in general and in your experience, if this repair was done do you feel I could reasonably expect a few more years trouble-free use from it? Basically this will help to establish whether the repair will be economic or not.

    I’ve never removed the kick boards under the dishwasher but I have done so with the one under the washing machine and tumble dryer a few times. The very first time I removed it I managed to break the only clip holding that one in place…
    Anyway, that’s my problem. Assuming I get the kick board off, how heavy is a dishwasher to move? Also, how on earth do you level it up when it is back in its recess? I have spirit levels, but none that I can use in such restricted height…

    It’ll have to come out whether it’s repaired (by me or an engineer) or replaced. So, I might as well have a go at removing it myself. S’pose I’d best alert the local fire station!

    Sorry to ask so many questions but this is all new to me.

    Certainly not.

    30 minutes in total

    The part (00165281) costs about £18 + 30 mins labour

    Oh somewhere between 5 and 10 years if used once a day. 5 years max if the water softener isn’t used because those 3 in 1 tablets are no alternative to softened water. 10 years if the manufacturers recommendations were adhered to the letter.

    Take a read of the installation instructions first (if you can’t find your copy then download one from Neff’s spare part website. It is essential you reverse the installation procedure with regard to unscrewing the top fixings and lowering the adjustable feet before dragging it out. Once you do that it is not heavy at all and comes out easily as a rule.

    Again it’s all shown in those all important installation instructions.

    Hmmm … sounds like it’s pretty much at end of life.

    I’ve a busy weekend but will download and peruse Neff’s documentation in due course – probably Monday, with luck! Will let you know how I get on.

    Many thanks and much respect for your advice.

    Re: NEFF 8406 Cycle never completes

    Well, it’s more broken now.

    It no longer seems to heat the water … until I switch it off! (Simply pausing doesn’t seem to work though I haven’t checked this exhaustively). When power resumes, a few minutes later the water is much hotter? The cold rinse cycle still works.
    Also now the dishes aren’t cleaned properly, in particular tea stains aren’t removed – even after I’ve power cycled it and left it running with the water heating up.
    Does this make any sense to you?

    Re. the installation manual all I could find was a single illustrated sheet with minimal text (in various languages). Haven’t had chance to look at it properly yet, but first impressions are that removing it looks surprisingly fiddly…

    Probably won’t get chance to do anything much more in the next few days. I’m coming round to the opinion that I should either buy a new one (Siemens look good) or get a local engineer in (the preferred guy is away until mid-October). I’m surprised that it isn’t easy to view these integrated dishwashers prior to purchase – several shops claimed to sell them but didn’t have them on display. Pity. Any thoughts or comments you might have would be very helpful!

    Anyhow, I really appreciate all your help but really don’t want to use up your time or goodwill unnecessarily so will understand if you think that it isn’t worth spending any more time on this – after all, it’s still finding new ways to go wrong!

    Yes it is somewhat fiddly getting integrateds in and out. Yes the installation instruction leaflet illustrations aren’t terribly obvious as you have observed. On plate 4 it shows how to raise and lower the feet. Plate 8 removing the outer decor door and so on. Not brilliant I must agree but a job we in the trade know how to do with our eyes shut almost. Perhaps calling out your preferred tradesman might be a good next option? One to consider anyway. 🙂

    Re: NEFF 8406 Cycle never completes

    Yes, I’m coming to the same opinion that trying to repair it myself is probably not the best option, mainly because the unit is finding new ways to go wrong and I think a hands-on examination by someone far more knowledgeable than me is the way to go.
    As ever, many thanks for your help and advice, much appreciated!

    Re: NEFF 8406 Cycle never completes [Finished]

    Eventually decided to get a replacement because the old unit kept failing in different ways. Finally got the new dishwasher (another Neff) plumbed in as part of the delivery – and I’m very glad I did. Turns out that when the house was built they apparently installed the white goods first and essentially built around them. The installer had a really hard time removing the old unit (a bit of waste pipe is still stuck behind the cabinet!) and an even harder time feeding the new pipework through (he had to drill new access holes and luckily – as he later discovered – these were high enough to avoid pipes behind the rear of the cabinet!). Hopefully it’ll be another decade or so before it has to come out again!
