Wolf Induction Cooktop Code E111: Communication error with the TC

What E111 means

On Wolf CI induction cooktops with the touchscreen control, such as the CI30460T/S and CI36560C/B, E111 is a communication error with the TC, meaning the control cannot exchange data with that part of the cooktop. You will see E111 on the display and some or all zones may stay off. A loose link, a power disturbance, or a failing control can cause the break in communication.

Common causes of E111

Communication link to the TC interrupted
Control board that has stopped responding
Power disturbance that knocked communication out

✓ One safe check you can try

1. Turn off all zones and remove cookware. 2. Let the cooktop sit with its breaker off for sixty seconds, then turn it on. 3. Wait for the display to start up and try one zone. 4. If E111 returns, leave the cooktop off and book us; link wiring and control boards are not safe for owners to handle.

! Why to stop there

A communication error can sit in a connector, the wiring, or a board, and only testing shows which.
The parts involved are under the glass next to live power.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E111E111 questions

What is the TC in E111?

The code refers to a part of the control called the TC. We do not need you to identify it; we test the link and the board to see where communication stops.

Will a reset fix E111?

Sometimes a power cycle restores the link. If the code returns, the connection or a board is likely failing and needs professional repair. We bring the likely parts so a second trip is rarely needed.

Can E111 appear after a storm?

A power disturbance can interrupt communication between control parts. A breaker reset is worth trying once, and if E111 is still there, we diagnose it.
