What to do when ERR04 shows on the rangeKind of codeControls and communication
The display, the main board or the induction power board lost contact with one another, or one of them failed its own self-check. A power dip, a loose cable or moisture from a boil-over is ruled out before a board is replaced, and a range that keeps heating while this code shows is switched off at the breaker.
Usually leads toKnobs, switches and controls
Knobs that spin or crack, touch keys that do nothing, blank displays, clocks that reset and control boards that switch the wrong thing.
Shows up asRange Control Panel Not Responding
The touch keys or knobs on the range do nothing, only some keys work, the display is blank or frozen, or it beeps without starting.

Before you book,
in this order.
Each step comes from Hestan's own guidance for ERR04 on its ranges. Follow it to the end: the last card says whether this is a visit.
Try a reset: turn the range's breaker off, wait a few seconds and turn it back on.
If ERR04 stays, keep cooking without the affected feature and book a visit at the earliest chance.
Still there?
It usually turns into knobs, switches and controls. Book with the code and the model number.
What not to do
ERR04 is not one of the codes that should stop you using the oven. Any code outside Hestan's four-code group is the kind that does.

Hestan range repair
Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
In Hestan's own words

Every code on this site is taken from the manufacturer's documentation, never from a forum or a parts listing. Hestan KRD dual-fuel and KRI induction ranges print the same oven table.
