    Hi,

    My Dishwasher – Bosch Logixx Auto SGS6962GB/13 (Jan 2002) has an intermittent (getting worse) problem. It started on the Eco cycle where it would appear to go thru the entire cycle apart from 1 Min (which shows on the display). When you open and look inside the wash seems not to have finished (like someone opened the door and didn’t turn it on again). If you close the door and press start it jumps way back in the cycle and carries on, sometimes to finish and sometimes to stick on 1 Min again so I started doing a reset too. Anyway we changed to the Auto cycle and it worked ok for a while too. Now this seems to be doing the same thing. I read some of your forum suggestions and have done the following :

    -Check water is coming in OK. Yes (top and bottom)
    -Clean all arms, filters, etc. Yes
    -Check if heater is working. Yes and No (on the intense cycle the heater heats to the right temp, but not on the Econo, Auto or Quick cycles ?!!)
    -Check for Dry joints on the Timer and Control PCB’s. Yes. (resoldered just to be sure, after unplugging of course!!).
    -When the cycle does finish OK, sometimes there are gritty bits at the top, salt smears and/or some dirty items (not a rotor arm problem though, I always check rotation before the cycle (and and after if I see a problem).
    -Check the pump empties OK. Yes it usually does, and I can hear it in the sink + no dirty water left in the machine.

    Still get the same issue.

    I can’t afford an engineer at this point, so I thought I ask what the likely parts I’d need are, their cost and possible labour time for this job might be ?

    Thanks

    Let me just assume that if you are living in a hard water area that you are regularly putting salt in the salt container first of all?

    The problem is possibly that the turbidity sensor (attached to the instantaneous water heater unit, is itself crudded up? Try a couple of maximum washes using a ‘dishwasher cleaner’ (without dishes of course) and see if that helps?

    Yes it is a Hard Water Area. I’ll try that and get back to you.

    Thanks

    Mmm, that didn’t seem to work. It still sits at 1 Min to go. I did notice that when I opened the door there was a sucking sound. I look in the sump and no water is there. I added a few bowls of water, closed the door and the machine carried on from around 68 mins on the Intensive cycle. It began by spraying water around inside, then went on to finish (timer at 0 Mins)?? Any other ideas ?

    Worth checking pressure chamber and ribbed hose from it to sump for gunge.

    Hi, I downloaded the exploded parts view for my dishwasher, however the descriptors are in German. Do you have part codes for the Instantaneous Water heater and Pressure Chamber so I can clean/check the correct parts please ?
    Thanks
    Happy Christmas btw 🙂

    Hi Jo,

    I don’t suppose it is any comfort for you to hear that my identical machine has an identical problem. My engineer reckoned that some inlet pipe thing was gunked up and causing the machine to think it was leaking so that it ran the pump continuously. The machine did then work for a couple of weeks (although the getting stuck on 1 minute problem remained) but it has now happened again. If you, or anyone else, has managed to fix this problem I’d love to hear how.

    All that has been checked and cleaned. Problem remains. Am now cutting my losses and buying a new machine. Not Bosch – never again.

    Im sorry to hear that you wont be buying Bosch again. They are one of the most reliable appliances on the market.
    Its only 3 years old,surely it must be worth an engineer to look at. May be something simple, and may even cost less to fix than you think.
    If it was gunge causing the problem, this problem is not unique to Bosch.
    If you dont get the food scraped off in bin from the plates; and a quick rinse under tap before loading then this gunge; call it what you will,will accumulate.
    If you feel you must buy another dishwasher, I would still recommend Bosch or if you feeling flush Miele.
    Regards

    Re: Bosch SGS6962GB/13 Cycle Stuck on 1 Minute to go

    Hi Rachel, Gegsy etc.. just an update… I got by over Christmas by adding water to the machine at a particular point in the cycle and then the machine was able to finish the cycle.

    Clearly this is not workable, so the other day I set to taking the thing apart… Unplug, LHS of the machine take off side panel, unplug hoses from inlet and out let and recirc pipes (have a bowl and towels ready). clean these pipes as you go if poss. Took off and cleaned the water level regulator(263097) and cleaned out the gunked pressure chamber, float and tube running to sump (480748). Put back together and tried again running it for a couple of cycles on Intensive. I now notice the temp is getting to its target temp – it wasn’t before. So something has got better. However it still sticks on 1 min. So I believe there are multiple problems here.

    I’d now like to check the sensors attached to the instantaneous water heater mentioned in a previous post… there are 2 on the other side of the machine (165279 & 165281).
    1)Is this a possible problem area given the symptoms and
    2) How do I get them off to clean them or is it not possible without removing the whole instantaneous water heater ?

    Could it be a fualty PCB or is it more likely to be a mechanical/sensor issue?

    I doubt the PCB is at fault here but the latter could be the issue?

    Basically at some stage during the cycle your machine is ‘timing-out’ from it’s intended sequence. So of all the things you have cleaned and checked it only leaves me with two thoughts. Firstly, are you sure the drain coupling to your sink is clear and free flowing?

    Secondly, it could be a crudded up instanteneous water heater unit soil sensor? (Access to that involves removing the tub first though 🙁 )
