Code appears and the whole cooktop stops working
The display shows E9000 or E9010, none of the cooking zones heat, and the controls may seem frozen or limited.
Start here: Start with a full breaker reset and a dry, clean control surface check.
Cooktop Error Troubleshooting
Thermador Induction Cooktop E9000 E9010 Error
Direct answer: If your Thermador induction cooktop shows E9000 or E9010, treat it first like a control or power fault, not a bad pan problem. A full breaker reset and a careful check for moisture, stuck touch controls, or a one-zone-only failure are the safest first moves.
Most likely: The most likely causes are a control glitch after a power disturbance, moisture or residue confusing the touch controls, or an internal cooktop control failure if the code comes right back after a proper reset.
Start by separating three lookalikes: whole cooktop dead with the code, controls light up but no burner responds, or only one zone acts up. That tells you whether you’re dealing with a simple reset issue, a touch-control problem, or an internal cooktop component fault. Reality check: if the code returns immediately after a true power reset, this usually is not something a new pan will fix. Common wrong move: tapping the glass harder or repeatedly cycling the controls without cutting power long enough to clear the fault.
Don’t start with: Don’t start with part swapping or by prying into the cooktop while power is still on. These units store and route line voltage, and guesswork gets expensive fast.
If every zone is downDo a full breaker-off reset before assuming a failed part.
If only one area failsSuspect a single cooktop induction element or its local control path, not the whole unit.

What this error usually looks like in the kitchen
Code appears after cleaning or a boil-over
The cooktop was recently wiped down, steam rolled across the controls, or liquid spilled near the touch panel before the error showed up.
Start here: Dry the glass and control area completely, then reset power and test again.
Controls seem alive but one zone will not run
Some indicators work, but one burner area throws the code or refuses to detect a pan while other zones still operate.
Start here: Test each zone one at a time to separate a single induction element fault from a whole-control problem.
Code comes back immediately after power is restored
You reset the breaker, the cooktop boots up, and the same error returns before normal cooking starts.
Start here: Move quickly to confirming a control or internal component fault and stop short of live electrical disassembly.
Most likely causes
1. Temporary control lockup after a power disturbance
These errors often show up after a flicker, outage, or breaker trip, and the cooktop may need a full power-down long enough for the electronics to clear.
Quick check: Turn the cooktop off at the breaker for several minutes, not just at the touch panel, then restore power and test one burner.
2. Moisture or residue on the touch-control area
Induction touch panels can misread water film, cleaner residue, or a damp cloth left on the glass as a stuck command or control fault.
Quick check: Dry the glass and control strip fully with a soft cloth and make sure nothing is resting on the panel.
3. Single cooktop induction element or local sensor fault
If only one zone fails while the others still heat, the problem is usually local to that burner area rather than the incoming power.
Quick check: Use the same pan on each zone and note whether the error follows one cooking zone only.
4. Failed cooktop control interface or main control board
If the code returns immediately after a proper reset and the surface is dry and clear, the electronics inside the cooktop are the stronger suspect.
Quick check: Watch whether the code appears before you even select a burner or only when a specific zone is called to heat.
Step-by-step fix
Step 1: Do a real power reset first
A quick off-on at the touch panel does not clear many induction faults. A full power-down is the cleanest first check and costs nothing.
- Turn all cooktop controls off.
- Switch the cooktop breaker off fully.
- Leave power off for at least 5 minutes so the control can discharge and reboot cleanly.
- Turn the breaker back on.
- Test one burner with a known good induction-ready pan.
Next move: If the code clears and the burner heats normally, the fault was likely a temporary control lockup. If the code returns right away or the cooktop still will not respond, keep going.
What to conclude: A successful reset points to a glitch, often after a power event. An immediate return points more toward moisture, a stuck control input, or an internal cooktop fault.
Stop if:
- The breaker will not stay on.
- You smell burning plastic or hot electronics.
- The cooktop sparks, pops, or shows visible damage under the glass.
Step 2: Rule out moisture, residue, and a stuck touch input
A damp control area can make an induction cooktop act like a button is being held down or like the control is failing.
- Make sure the cooktop is off.
- Wipe the entire glass surface and especially the touch-control area with a dry soft cloth.
- If there is greasy film, use a lightly damp cloth with a drop of mild dish soap, then wipe again with clean water and dry thoroughly.
- Remove any pan, utensil, towel, or foil from the surface.
- Wait a few minutes, then test again.
Next move: If the code clears after drying and cleaning, the control was likely being confused by moisture or residue. If nothing changes, the problem is probably not just surface contamination.
What to conclude: This step separates a false touch-panel fault from a deeper electrical problem inside the cooktop.
Step 3: Find out whether the whole cooktop is affected or just one zone
This is the fastest way to separate a main control problem from a single burner-area failure.
- Use one induction-compatible pan that you know works.
- Test each cooking zone one at a time on a low setting first.
- Note whether every zone fails, or only one specific zone throws the error or refuses to heat.
- Watch whether the error appears as soon as the cooktop powers up or only when a certain zone is selected.
Next move: If all zones work except one, you have narrowed it to a local cooktop component problem. If every zone fails or the code appears before any zone is selected, suspect the main control side of the cooktop.
Step 4: Check the simple external conditions that can mimic a fault
Before blaming internal parts, make sure the cooktop is not reacting to a pan issue, child lock, or unstable power supply.
- Confirm the pan is induction-ready and flat-bottomed.
- Try the same pan on another zone and a different known good pan on the problem zone.
- Check whether the control lock or child lock is active and clear it if needed.
- Look for signs of a recent power issue in the kitchen, like a tripped breaker or other appliances resetting.
Next move: If a different pan or clearing the lock restores operation, you avoided an unnecessary repair. If the code persists with known good cookware and normal controls, the fault is likely inside the cooktop.
Step 5: Act on the failure pattern instead of guessing
By now you should know whether the issue cleared, follows one zone, or points to the main controls. That is enough to choose the next move without random parts buying.
- If the reset fixed it and the code stays gone, keep using the cooktop and watch for repeat failures after future power flickers.
- If one zone consistently fails while the others work, plan for service around that burner area and the matching cooktop induction element branch.
- If the code returns immediately on startup or affects the whole cooktop, plan for service around the cooktop control interface or main control board branch.
- If the cooktop has repeat breaker trips, burning smell, visible damage, or liquid intrusion, stop using it and schedule appliance service.
A good result: If the cooktop now runs normally, verify all zones heat and the controls respond consistently before calling it done.
If not: If the code remains or returns quickly, internal diagnosis and likely part replacement are next.
What to conclude: A repeat code after the basic checks usually means an internal cooktop component has failed or the unit has a power-supply issue that needs meter-based diagnosis.

FAQ
What do E9000 and E9010 usually mean on an induction cooktop?
In practical terms, they usually point to a control, communication, or power-related fault rather than a simple cookware issue. A full breaker reset is the first thing to try, then you separate whole-cooktop failure from one-zone-only failure.
Can a bad pan cause E9000 or E9010?
Usually not if the code appears at startup or affects the whole cooktop. A pan issue is more likely when one zone will not detect cookware but the rest of the cooktop behaves normally.
How long should I leave the breaker off to reset the cooktop?
Leave it off for at least 5 minutes. A quick flip off and back on often is not long enough for the control to clear the fault.
If only one burner fails, is the main board still bad?
It can be, but one dead zone more often points to a local burner-area problem such as the cooktop induction element or its sensing path. When every zone is affected, the main control side becomes more likely.
Should I keep using the cooktop if the code clears once?
Yes, but watch it closely. Test all zones and pay attention after the next power flicker or after cleaning. If the code returns, especially right away, the cooktop likely has an internal fault that needs repair.
When is this a job for a pro?
Call for service if the breaker trips, the code returns immediately after a proper reset, there is a burning smell, the glass is damaged, or liquid may have gotten inside the cooktop. Those are not good guess-and-buy situations.
