C85
Teka C85 on an induction hob: unsuitable pot or pan used
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
On Teka induction hobs, C85 appearing on the indicator of one of the hotplates means the pot or pan being used is of an unsuited type. Switch off the hob, switch it on again and try with another pot or pan that has a thick, flat ferromagnetic base of the right diameter.
Safety first
Stop and check this first
- To avoid scratching or metallic sheens on the ceramic glass while swapping pans after a C85 message, lift pots instead of dragging them across the glass and keep their undersides clean and dry.
Safe checks you can perform
- Test the underside of the pan with a magnet
- Switch the hob off and on again, then try another pan
- Try the known-good pot on another zone of the hob

What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Induction coil and pan-sensor diagnosis by Teka service
What they doWhen a hotplate continues to show C85 after switching off and on and trying verified ferromagnetic cookware, a Teka service engineer inspects the induction coil and the pan-recognition circuit on the power board.
They must show youhow the affected zone behaves with a standard induction test vessel and the state of the coil.
In writingthe C85 code confirmed, the zone inspected, the electrical test findings and any part replaced.
Pan recognition and heating test after repair
What they doAfter replacing or adjusting the internal module, the engineer tests the hotplate with your suitable pots to ensure immediate pan detection and stable heating.
They must show youthe zone heating water in your induction pot with no C85 on the indicator.
In writingthe cookware tested, the power setting used and confirmation that C85 did not return.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Test the underside of the pan with a magnet
- Who:
- you, with the pot or pan lifted off the hob.
- How:
- check that a magnet sticks firmly to the underside of the container, inspect that the base is thick, one-piece and completely flat, and make sure the base diameter itself matches the size of the cooking zone.
- Result that matters:
- you confirm whether the pan lacks a ferromagnetic flat base or is too small for the hotplate.
- If the magnet does not hold or the bottom is warped or undersized, set that pan aside for induction use.
- If the magnet holds strongly and the base is flat, reset the hob after C85 and test with another pan as below.
- Evidence to keep:
- a photo of the pan base and magnet test.

Switch the hob off and on again, then try another pan
- Who:
- you, following the Teka troubleshooting instruction.
- How:
- switch off the hob at the touch control, switch it back on again, place a different induction-compatible pot with some water squarely on the hotplate and select a power level.
- Result that matters:
- the indicator holds the selected power setting without showing C85.
- If the hotplate heats normally with the second pot, the original container caused the C85 message.
- If C85 or the pan-detection symbol appears again even with a suitable pot, carry out the third zone check.
- Evidence to keep:
- a photo of the hotplate indicator while testing the second pot.

Try the known-good pot on another zone of the hob
- Who:
- you.
- How:
- move that second ferromagnetic pot to another cooking zone of matching size on the Teka hob and switch that zone on briefly to see if it heats.
- Result that matters:
- you see whether the pan works elsewhere on the hob or whether only one hotplate rejects it.
- If the pot heats on other zones but always triggers C85 on one specific hotplate, note which zone fails for the technician.
- If every zone rejects the pot, test with a thicker cast-iron or multi-layer ferromagnetic pan.
- Evidence to keep:
- a note of which hotplate showed C85 and which zones accepted the pot.

What it means
The Teka IZC 63632 MPT induction hob user manual lists C85 in its troubleshooting section: when C85 appears on the indicator of one of the hotplates, the pot or pan used is of an unsuited type. Teka instructs you to switch off the hob, switch it on again and try with another pot or pan, noting across its manuals that induction zones require a thick, completely flat ferromagnetic bottom that attracts a magnet and matches the cooking zone diameter. A C85 code alone never proves that the induction coil or pan sensor has failed.
Warnings and stop conditions
- Loweditorial warning
To avoid scratching or metallic sheens on the ceramic glass while swapping pans after a C85 message, lift pots instead of dragging them across the glass and keep their undersides clean and dry.

Symptoms and causes
Probable causes · in order
- Cookware base is not ferromagnetic or couples poorlyCommon
The induction circuit senses that the pot or pan material does not couple properly with the magnetic field and displays C85 on that hotplate.
Evidence: Teka Manual de instrucciones placa de inducción IZF 68780 MST · Teka User Manual induction hob IZC 63632 MPT (ES/PT/EN/DE/FR)
- Base diameter too small or uneven undersideCommon
Teka notes that a pan's top rim is wider than its base and requires a thick, completely flat bottom matching the minimum diameter for the selected zone.

- Pan-detection circuit fault on that hotplateLess common
If C85 still appears after restarting and testing known-good ferromagnetic pots that work on other zones, the zone's detection electronics need professional attention.
