Symptoms
The same pot heats on another zone but the selected zone reports no pan.
A status icon is not the same as a successful result. The same pot heats on another zone but the selected zone reports no pan. Reproduce the outcome itself before treating a setting as the cause.
- The failing path: The same pot heats on another zone but the selected zone reports no pan.
- Control test: Test one known induction-compatible pot on each cool zone under manual instructions.
- A successful outcome: A supported pan is detected reliably on the chosen zone.
Why It Happens
The physical appliance and its cloud notifications can disagree. Prioritize the local safety indicators and the published operating limits of the model.
There are three genuinely different layers worth checking; use the observation in the table to decide which one is implicated. None of these is proven merely by the symptoms.
- Pan base too small for zone. This explanation predicts a different result in the comparison test or the more advanced inspection.
- Zone sensor fault. This explanation predicts a different result in the comparison test or the more advanced inspection.
- Moisture on control surface. This explanation predicts a different result in the comparison test or the more advanced inspection.
Before Making Changes
Stop using the hob if glass is cracked; do not open high-voltage components.
Save the current configuration or capture screenshots of the exact option values; where a file or recording is involved, work on a disposable duplicate. If this is shared equipment, ask the owner or administrator before changing it. Prefer a safe test item over real customers, medical decisions, paid transactions or irreplaceable data.
Write down the device model, platform, observed time of failure, and which action still works. These details will distinguish an unsupported feature from a malfunction and will be useful if escalation is required.
Problem-Specific Diagnosis
Use the following route rather than guessing based on a product name. The expected differences are designed for this particular failure.
| Action or observation | Meaning of the result | Decision |
|---|---|---|
| Test one known induction-compatible pot on each cool zone under manual instructions. | Does the failure follow the affected file, profile, connection or location? | Keep this result as the baseline; do not alter two systems at once. |
| Clean and dry the cooktop and center the pot over the affected zone. | Does the low-impact correction restore the exact failure without altering the control case? | Re-test; reverse the change if the original symptom is unchanged. |
| Compare pot base diameter, zone pairing and error history before requesting authorized service. | Does this separate zone sensor fault from moisture on control surface? | Use documented diagnostic views rather than blind replacement. |
| A supported pan is detected reliably on the chosen zone. | Is the same original symptom gone after a normal repeat? | Record the pass condition and preserve the working settings. |
If the control case fails as well, the fault may be broader than this guide. Stop at that point and check the shared power, account, access or media path before applying the narrow fix.
Beginner and Advanced Paths
Start with the reversible Beginner path. The Advanced path examines a different layer when the first route fails; it is not a repetition of the same restart or setting.
Step-by-Step Troubleshooting
Choose the simple reversible checks first, then investigate the deeper system layer only if necessary.
Record the exact failure
Confirm the behavior without guessing: The same pot heats on another zone but the selected zone reports no pan. Note the affected account, file, connection or physical control and record the current settings. Stop using the hob if glass is cracked; do not open high-voltage components.
Run the passing comparison
Test one known induction-compatible pot on each cool zone under manual instructions. Keep the working and failing cases separate. If both fail, stop and investigate the common path instead of forcing a narrow repair.
Apply the least disruptive correction
Clean and dry the cooktop and center the pot over the affected zone. Change only this setting or route; do not reset unrelated profiles, storage or pairing records. Save the previous value so it can be restored.
Retest and keep the result
A supported pan is detected reliably on the chosen zone. Repeat after a normal reopening or reconnect. If the control case gets worse, undo the last change and write down the difference.
Separate the three underlying layers
Test the hypotheses independently: pan base too small for zone; zone sensor fault; moisture on control surface. A green status indicator does not distinguish them. Use the recorded control case as evidence.
Inspect the deeper component
Compare pot base diameter, zone pairing and error history before requesting authorized service. Use only read-only diagnostics or documented configuration screens first. Capture logs and timestamps rather than removing the component or reinstalling software blindly.
Cross-check with an independent path
Where possible, repeat “Test one known induction-compatible pot on each cool zone under manual instructions.” using a second supported account, safe sample file, physical input, known-good cable or alternate compatible application. Change only one variable and note which outcome follows it.
Choose a reversible targeted escalation
If the deeper check isolates a fault, use a vendor-supported fix or authorized service for that layer; otherwise restore original values. Finish only when: A supported pan is detected reliably on the chosen zone. Stop using the hob if glass is cracked; do not open high-voltage components.

Solution Checklist
Common Mistakes to Avoid
- Treating pan base too small for zone as certain just because the behavior looks familiar.
- Changing several independent settings together, which makes the result impossible to interpret.
- Skipping the safety boundary: Stop using the hob if glass is cracked; do not open high-voltage components.
- Calling the issue fixed after one status indicator changes but before repeating the original operation.
- Discarding the working configuration or the only original file before a replacement has been verified.
How to Verify the Fix
A supported pan is detected reliably on the chosen zone.
Use the same baseline case: Test one known induction-compatible pot on each cool zone under manual instructions. Then repeat the previously failing operation after a normal close-and-open, reconnect or next scheduled cycle, whichever matches the scenario. Confirm the part of the system that was already working is still unaffected.
Where a result can be measured, retain the test timestamp, file name, screenshot or device state. A temporary success that cannot be repeated is not yet a confirmed repair.
If the Problem Continues
Escalate from the surface symptom to the narrower mechanism: Compare pot base diameter, zone pairing and error history before requesting authorized service. If this identifies a hardware, account-policy or service limitation, use the manufacturer’s authorized support route rather than bypassing controls.
When opening a support case, supply the model, software/firmware version actually installed, the failing operation, the successful comparison, the three possible explanations checked, and the final observed result. Redact account identifiers, access codes, serial-number photos and personal information from public posts.
Prevent Recurrence
Keep a short note of the confirmed working configuration, particularly the setting implicated by pan base too small for zone. Repeat the disposable comparison after an app update, device replacement, major account change or new connection only when that change plausibly affects this issue.
Retain a recovery path: spare test material, a saved profile, a restore point, a backup copy or official service information, as appropriate for the device. Do not schedule risky resets as routine maintenance.
FAQ
Is pan base too small for zone definitely the reason this happens?
No. The same symptom can come from zone sensor fault or moisture on control surface. First compare the affected and unaffected paths: Test one known induction-compatible pot on each cool zone under manual instructions. Do not assume any cause without a different outcome.
How can I safely rule out zone sensor fault?
Try the reversible correction only after documenting the control: Clean and dry the cooktop and center the pot over the affected zone. If the behavior does not change, restore the old value and use the deeper observation: Compare pot base diameter, zone pairing and error history before requesting authorized service.
What if moisture on control surface turns out to be responsible?
Do not force an unsupported setting or a factory reset. Keep the evidence and ask the manufacturer or responsible administrator to investigate the isolated layer. The measurable pass condition remains: A supported pan is detected reliably on the chosen zone.
