Family-owned and run by Viktor, owner and lead technician. Rated 5.0★ from 454 Google reviews. Call (619) 877-6701. Wolf gas, electric, and induction control indicators are model-specific. Photograph the complete display, zone, letters, numbers, and sequence before resetting power, and record what the cooktop was doing when the message appeared.
Safety first: if you smell gas, see uncontrolled flame, repeated breaker trips, smoke, or overheating, stop using the appliance and follow the appropriate utility or emergency procedure.
Symptom context
Identify normal status indicators before assuming a fault
Lock, auto-lock, showroom, pan detection, bridge-zone, hot-surface, timer, and power-level indicators can look unfamiliar without the model guide. Other messages may identify power, temperature, fan, sensor, module, or communication conditions.
Generic code lists are unreliable across model families. The full model number, affected zone, cookware, operating level, and recurrence pattern provide the correct context.
Display timing is useful evidence. A message present at startup follows a different diagnostic path from one that appears only after several minutes at high power. Note whether one zone, every zone, or only the touch panel changes and whether normal operation returns after the surface cools.
After the cooktop is cool, remove cookware and objects from the control area and wipe the touch surface dry with a soft cloth. Moisture, residue, or an item resting over a control can interfere with touch input on some models. Stop if the glass is damaged or the controls feel unusually hot.
Owner-safe checks
Checks you can make without opening the appliance
Record the trigger
Note cookware, zone, bridge setting, time in use, spill, outage, or installation event.
Check owner-level states
Use the official model guide for lock, showroom, pan-detection, timer, and hot-surface meanings.
Use one controlled reset
If there is no overheating or repeated trip, switch the breaker off briefly, restore power, and retest once.
Preserve recurring evidence
If the message returns, stop resetting and record the sequence for diagnosis.
Professional diagnosis
What the technician may evaluate
- Exact model and stored fault history
- Incoming power and terminal connections
- Zone sensors, temperature protection, and cooling
- User interface and control communication
- Induction or electric power modules
- Spill, installation, ventilation, and recent service
Appointment preparation
Information that speeds diagnosis
- Send display photos or video.
- Provide model and serial number.
- Record zone, cookware, level, and elapsed time.
- Mention lock, showroom, bridge, spill, or outage.
- Do not open the cooktop or repeatedly clear the fault.
Stop troubleshooting
Do not continue operating the range when:
- The breaker repeatedly trips.
- The glass is cracked or controls overheat.
- A gas odor or abnormal flame appears on a gas model.
- The fault returns immediately after one safe reset.

FAQ
Wolf Cooktop Error Codes or Control Problems questions
Can one code mean the same thing on every Wolf cooktop?
No. Meaning varies by product family and control generation. Use the complete model and exact display.
Is blinking always an error?
No. It may indicate pan detection, lock, bridge, showroom, or another status. The model guide and operating context matter.
Why does only one zone show a message?
Zone-specific sensing, cookware detection, temperature, or power electronics can differ from the rest of the cooktop.
Should I reset the breaker repeatedly?
No. One controlled reset is enough. A recurring fault should be preserved for diagnosis.
How much is the residential diagnostic?
The residential diagnostic is $99 and is credited toward an approved repair. Findings and the proposed repair are explained before work proceeds.
Does a Wolf gas cooktop have error codes?
No. Wolf gas CG cooktops do not display error codes. Their faults show up as clicking, no spark, or no flame. The codes on this page apply to induction and electric cooktops only.
Can I clear an F7 code myself?
Often, yes. Turn the cooktop off and let it cool. Clear the cabinet below so air can flow. Reset the breaker. If F7 returns, the cooling fan or board may need repair, and the installation may need checking.
Why does my Wolf cooktop show SHR and not heat?
SHR, 5HR or SHOW means the cooktop is in showroom mode, so it will not heat. This can happen after a reset. Follow the manual to exit showroom mode, or call us to do it.
Is error 47 serious?
It means the boards are not communicating. Sometimes a breaker reset clears it. If it comes back, a technician checks wiring and boards. It is not a safety hazard, but the cooktop will not work until fixed.
Local notes · San Diego County
Wolf Cooktop Error Codes: What F7, 3, 47, 22 and SHR Mean
Wolf error codes come from the induction and electric cooktops; gas CG models do not display codes. The codes Wolf documents: F7 on legacy CT induction means the electronics passed 158 F. Error 3 on CI induction means moisture or an object on the control area. Error 47 on CI induction is a communication fault between boards. Error 22 on CE electric is a stuck key or pad error. SHR, 5HR or SHOW means showroom mode, where the cooktop will not heat. Many of these can be cleared safely before a service call.
Valley Heat and Code F7: The County Link
Induction cooktops generate heat in the pan, but the power electronics underneath also get warm and depend on a cooling fan. Wolf's CT series shuts down with F7 when those electronics exceed 158 F, usually because of poor ventilation under the cooktop or an installation that blocks air. San Diego County's inland valleys make that margin smaller. El Cajon averages 88.6 F for the August daily high and reaches about 100 F on its hottest days, and a cabinet over an oven or near a west-facing window gets hotter still. Dust matters too. Cooling fan intakes under the cooktop collect dust and pet hair, and Santa Ana winds push fine grit indoors. On the coast, damp marine air and salt can corrode connectors, which can affect board communication. For touch controls, steam from pots and moisture from wiping can trigger CI error 3. Power sags during September heat waves can also disturb electronic controls, which is why Wolf's standard reset is a breaker cycle. Gas models in the county do not display codes, but they have their own ignition issues covered elsewhere.
Code Groups, Their Meanings and What to Do
F7 (CT induction): electronics overheated
Symptom: Zones shut off mid-cooking and F7 appears. Cause: Electronics exceeded 158 F, often from blocked ventilation, a cabinet that traps heat, or a ventilator or cooling fan not running. Fix: Let the unit cool, clear any airflow blockage, and reset the breaker. If F7 returns, the fan or board needs service.
3 or 03 (CI induction): moisture or object on controls
Symptom: Continuous tone or controls that stop responding. Cause: Water, a cloth, or cookware on the touch control area. Fix: Dry the control area, remove objects, and reset the breaker for 30 seconds. If it persists, the touch control may need replacement.
47 (CI induction): communication fault
Symptom: Error 47 with no heating. Cause: Loss of LIN communication between boards, from wiring or board failure. Fix: A breaker reset may clear a one-time fault. If it returns, a technician checks wiring and boards.
22 (CE electric) and SHR, 5HR or SHOW
Symptom: Error 22 with a stuck key, or a display that reads SHR, 5HR or SHOW with no heating. Cause: Error 22 is a pad or stuck-key error. SHR, 5HR and SHOW mean showroom mode is active. Fix: Clean and dry the pad area for error 22. For showroom mode, follow the manual to exit, or call us.
Preventing Codes on Induction and Electric Tops
Keep the control area dry and clear; Wolf specifically ties error 3 to moisture and objects there. Keep the cabinet below an induction cooktop open for ventilation as Wolf specifies, and do not store items that block airflow. Vacuum around the fan intake if it is reachable. Use induction-compatible cookware.
- Wipe spills off the control area immediately
- Keep the cabinet under the cooktop clear of stored items
- Vacuum the intake area every 3 months with pets
- Test pans with a magnet before first use
- Reset the breaker after power outages
What a Wolf Code Service Visit Covers
Send us the exact code, the model and serial number, and when the code appears. Our technician checks ventilation and cooling fan operation first for F7, then tests the touch control, wiring and boards for communication errors. For CI and CE units, we confirm the control area and pad function. Please clear the cooktop surface and base cabinet so we can reach the unit.
Code Repairs and Replacement Value
Touch controls, fans and wiring repairs are routine. A power board failure on an older CT induction unit may approach replacement cost, and a new cooktop may not match your cutout. Our $99 diagnostic, credited toward the repair, helps you decide.
