Question about Gaggenau 47 in. CK 596 Electric Cooktop

3 Answers

Ck596-615 i have a 5 burner gaggenau cooktop that has always had touch sensor problems. The touch sensors work fine with the power levels and we have always have problems the power switch. if you put a paper towel over your finger, the on/off works fine. I took it apart and saw 2 led sensors. There seems no way to adjust sensitivity. There is a red button that has adjust on a sisterboard but that may be for something else. Is there a simple way to adjust or do i need a new board (700$). i should call gaggenau and scream because it has never worked reliably.

    Hi - Not a problem or a solution, sorry; just curious to know how you like this cooktop? I've seen it advertised, and I thought the shape looks interesting - it can be used in a corner or along a regular counter, right?

    Many thanks!

    Not really a comment, rather a similar question
    I've got the same gaggenau cooktop and it has neither worked reliably. As long as gaggenau has sold the board as a retail part I spent a lot of money buying one ever second year . But now Gaggenau has definitely stopped the retail parts for this cooking top and just let the customer alone, without any alternative solution. That's the way they do in Germany. So a friend of mine tried the solution proposed by Slinger5586 but got no success with the old command with a reset button. I've got another command but without reset button. Is somebody knowing how to recalibrate the sensors with this command? I'll be very grateful for a solution because otherwise I have no other possibility than to rebuild this part of my kitchen since there is no other cooking top fitting in the gaggenau hole.
    Many thanks in advance. Corine

    updated - Hurricane Sandy (2012) and the power outage fried the logic board - got a new board and it was a -2 version of the board. Looked the same but firmware or something else changed. Cost about 600$ and the thing works great. No more problems with the light sensors. Gald I can still get parts because this unit is irreplacable unless i get new granite. There is NO electric cooktop that fits in the hole or an expanded version of the hole. No one makes a glass cooktop that large.

  • kova3 Dec 09, 2013

    i did find the calibration instructions online for the older -1 version of the board. It probably would have worked.

    Hi kova3 - I've got a similar problem with the cooktop since more than a year :-(( No way to find any instructions or a new board here in Germany. It would be great if you could tell me where you found the calibration instructions and also where you got the new board. Many thanks!

    SInce I posted this, i had a power surge and it fried the logic board. I ordered a new board (approx 690$) and it was a REV-2 board. Seems they fixed the problem and it works great like it should have in hte first place. WOrks grat with overhead halogen lights adn bright LED's. Works great in bright sunlight too.

I had the same problem except I had more than one sensor causing concern. I have repaired it successfully by recalibrating the sensors. This is really easy to do, search the internet for the procedure and go to your local camera supply and buy a "gray card". I purchased an 8" X 10" gray card for $7.99 cut it in half so I could cover all of the sensors and pushed the reset button. It works perfectly now. Just a note on cleaning the underside of the glass; I did this first and gained nothing. Recalibrating the sensors was the answer. The appliance parts site and Bosch want $50.00 for the same gray card; they call it a kit, but its two 8x10's and a 4x4.

The underside of the glass had some dirt and I cleaned it with a towel only. It works much better, especially with the overhead light from the range hood on. I may take it apart and clean it with alcohol or windex again. Irritating, especially when the top costs over 3200$.

GE profile JP969 fault code F113

I took the cooktop apart I removed the terminal from the main electronic board . The left front burner has 2 white wires and 2 yellow (my case). The 2 white wires lead to the RTD sensor.With an electric meter set on OHMS check continuity between the two wires leading to the RTD sensor .If the reading is more than 1030 ohms is good if not than you need to replace the whole burner that comes as a complete unit with sensor and ribbon heating element.I found it on line for $114.00 +shipping.I wish they sold only the sensor but it would've been too cheap and not worth it for the makers . All connections to that burner are very easy put back together . Some suppliers may ask for as much as $175-$195 for the complete unit .

My 5-burner 36" gaggenau has stopped working. I

What the problem is a part in the cooktop that opens to let gas flow to the knobs as soon as they are turned on is bad and no gas coming to surface unit burners. This a safety feature that the German goverment(where Gaggenau is made) requires that part to prevent a gas leak when cooktop is off.

Burner light stays on


This is caused by a faulty sensor that is located between the burner element and the top. To replace the faulty part you will need to uninstall the cooktop and remove the glass top. The sensor is a rod a little smaller than a pencil that you will see right on top of that burner.

If you choose not to replace the sensor it will not cause any issues other than you will have to live with that light constantly on and you will know when the top is hot for that element.

The cooktop will not turn on. The little red light in the lower right corner of the touch panel is blinking. If one touches and holds it it does not turn on a burner per usual. The timer function works....

I'm going to assume this is a new installation, either way, it sounds as if you're only getting one leg of your 220v circuit, which wld run the timer and lights but not enough to power the burners. This is prly not something you shld try and repair yourself as a 220v circuit can cause some serious damage. At the least, you could first, TURN OFF THE BREAKER and then check the connections to the cooktop to make sure all connections are secure.

Burner light does not go off on Amana AKT3040

Sounds like a short in that particular burner circuit. Usually when the light stays on even after cool down the heat sensor is bad. This is inside the burner. If your getting white smoke the burner switch could also be shorted out.

Gaggenau clicking

Sounds like the spill got into one of the burner switches. This is not a big problem. Once it drys out it should return to normal. However if it keeps on clicking it could mean that one of the switches shorted out and will need to be replaced. The switches are located under the burner control knobs on the valve. Hope this helps.
