Cooktop error code Er22
DCS cooktop error code Er22: The control has lost confidence in what its own keys are telling it — either two things are connected that should not be, or a connection that should exist has gone. Which machines can raise it, what the maker publishes about it, and what to do next.

What we can confirm
Code Er22, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
Er22
The control has lost confidence in what its own keys are telling it — either two things are connected that should not be, or a connection that should exist has gone. On a coastal install the second is the common one: the ribbon that carries the touch panel to the board turns under the edge of the glass, and that turn is where salt-laden air reaches it. An electrically sound panel behind a corroded ribbon behaves exactly like a dead panel, and costs a fraction as much to put right.

What it narrows down to
A short circuit or an interruption in the way the keys are read.

What else belongs to the cooktops
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
A key has been held down continuously, so the top has stopped listening.
The supply voltage is outside what the cooktop will run on.
The programming options set in the control are not right for this machine.
A short circuit or an interruption in the way the keys are read.
A communication error inside the machine.
A temperature condition — the electronics under the glass have become too hot.

About Cooktop error code Er22
What Er22 means on this make
The control has lost confidence in what its own keys are telling it — either two things are connected that should not be, or a connection that should exist has gone. On a coastal install the second is the common one: the ribbon that carries the touch panel to the board turns under the edge of the glass, and that turn is where salt-laden air reaches it. An electrically sound panel behind a corroded ribbon behaves exactly like a dead panel, and costs a fraction as much to put right.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
induction cooktops. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 4 of the appliance types this site publishes — bbq grill, cooktop, oven and range — and publishes none at all for bbq grill, beverage center, outdoor kitchen appliance, range and range hood. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Dry the glass thoroughly and clear everything from it. Liquid under the edge produces this as readily as corrosion does.
- Power down at the breaker for a minute before deciding anything.
- If it stands, the panel and its ribbon are tested separately from the board. The cheap half is checked before the expensive half is ordered.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 526-4714 and describe what the panel is doing before booking anything.
