What E4
actually means.
Wolf gives E4 two meanings. On a CT series induction cooktop it means the heat sink on generator 3 is too hot. On a CI series cooktop it means the control board reports a configuration it cannot accept.

What to do when E4 shows on the cooktopKind of codeInduction power and coils
An induction zone could not drive its coil as the board planned: no pan was detected, the current ran too high or too low, or the power stage reported trouble. The pan base, the supply voltage and a clogged air intake are checked before the coil or the power board is replaced, and a top that trips its breaker is left switched off until then.
Usually leads toInduction board and coil repair
Induction zones that stop sensing pans, cut out, buzz or show codes, traced to the power boards, the coils, their sensors and the links to the controls.
Shows up asCooktop Element Not Heating
A coil stays black, a radiant ring under the glass never glows, or a zone warms so weakly that a pot of water will not boil.

Before you book,
in this order.
Each step comes from Wolf's own guidance for E4 on its cooktops. Follow it to the end: the last card says whether this is a visit.
Read the model label to see whether the cooktop is CT or CI.
On a CT top, let the cooktop cool; on either, switch the breaker off for 30 seconds and back on.
Book a visit if E4 comes back, and give the series letters with the code.
Still there?
It usually turns into induction board and coil repair. Book with the code and the model number.
What not to do
E4 is not a pan or cookware warning on either series. It is either a generator heat limit on CT tops or a control board configuration report on CI tops.

In Wolf's own words
Generator 3 heatsink temperature too high
