    Hi all,

    We have a 2yr old Bosch induction hob that is give some problems.
    When the ring(s) are turned off after cooking, it will start beeping with the indicator light for each ring flashing. After about 10 sec it stops beeping, but the lights continue to flash. The touch buttons don't respond to any input when this happens. After a minute or two, the touch controls will respond and allow me to switch it off.

    The hob surface is kept spotless and dry.

    Any ideas on why this would be happening?

    We also have this model hob and had the same symptoms and events until it completely broke down. We had an engineer out via Bosch who wanted up to 450 euro to replace circuit boards +90 euro call out, I told them to stick it as hob is only three years old. Standards say that white goods should last a minimum of 5 years. We are now trying to persue Bosch via the retailer. One other point, when the engineer had the hob apart I noticed that it was connected reverse polarity ie brown conductor connected to N and blue conductor connected to L. I pointed this out to engineer who said that Bosh knew about this and said it was ok. Any Comments!!!!!!!!

    Shouldn't matter as it's AC voltage (waits to be corrected).

    I accept that, but there are two PCB's in the hob, one is connected reverse polarity but the other is connected correct polarity, furthermore the PCB's are connected together with a ribbon cable. How does that work?

    ribbon cable is for the boards to 'communicate'
    polarity is not an issue inside ,will work either way ,it's rectified and transformed on the board anyway

    Thanks Guy's,
    I am learning all the time. Next question, how am I going to find out which PCB is faulty. At a guess the left hand one seems to be the master. The internal cooling fan is connected to the right hand PCB, I have heard the fan working but I have my doubts it works all the time even though the hob is hot, could it be the reason the PCB's are failing in this model hob.
