SAFETY NOTES & COMMON ERRORS

Usage Safety

1. Oven Installation Distance

Distance from walls or cabinets: Ensure at least 10–15 cm on both sides and 20 cm at the back for ventilation and to prevent overheating.

Do not install the oven in humid areas or near water sources (sink, faucet) to avoid electrical leakage.

Avoid placing the oven near refrigerators or other electronic appliances, as the heat may affect their performance.

Do not place heavy items or kitchenware on the oven surface as it may block ventilation.

2. Baking Safety Tips

Do not open the oven door suddenly when baking at high temperatures — hot steam can cause burns.

Always use heat-resistant gloves when placing or removing trays.

Avoid touching heating elements and fan during operation — temperatures may reach up to 250°C.

Check food through the oven glass rather than opening the door too often to avoid heat loss and steam burns.

3. Hot Glass Warning

Oven door glass can heat up to 70–90°C during use.

Warn children and the elderly not to touch the glass door or handle.

Some Häfele models feature triple-layer glass to reduce surface heat — but always use caution.

4. Electrical Safety

Use a dedicated circuit breaker (16–20A) to avoid overloading.

Do not use multi-socket adapters or extension cords, as they may overheat or catch fire.

Unplug the oven immediately if you smell burning or detect unusual behavior.

Never clean or service the oven while plugged in.

5. Food Safety

Do not let parchment paper or foil touch heating elements — fire hazard.

Do not reheat sealed foods (e.g., whole eggs) — risk of explosion due to pressure buildup.

Always use oven-safe bakeware recommended by the manufacturer.

6. Child Safety

Use the child lock function (if available).

Do not let children open the door or operate the oven unsupervised.

Keep children at a safe distance during operation to avoid burns or accidents.

7. Emergency Handling

If the oven emits sparks or smoke: unplug immediately and open the door only after it has cooled down.

If the glass door is cracked: stop using the oven; do not operate it to avoid further damage.

If there’s a fire inside: keep the door closed, unplug the oven, and do not open the door until the fire is extinguished.

Common Errors & How to Fix Them

1. Common Error Codes

2. Common Issues Without Error Codes

Oven not heating or heating weakly

Cause: Faulty element, low voltage, wrong mode

Fix: Recheck mode, test different outlet, call technician if no heat

Uneven heating (food not cooked evenly)

Cause: No convection fan, wrong rack placement, no preheating

Fix: Preheat for 10 mins, use fan mode, adjust rack to center

Fan not spinning

Cause: Dust or grease build-up, faulty motor

Fix: Clean fan, call for motor replacement if needed

Oven light not working

Cause: Burned-out bulb or faulty wire

Fix: Replace with heat-resistant oven bulb

Glass door is foggy or greasy

Cause: Steam and grease build-up

Fix: Use degreaser, remove triple-layer glass (if supported) for deep cleaning

Control panel frozen

Cause: Software glitch or unstable voltage

Fix: Unplug for 5–10 mins, restart oven

Strange noise during operation

Cause: Fan obstruction, dry rotating shaft

Fix: Clean and lubricate rotating parts

Food burnt outside, raw inside

Cause: Temperature too high or large portions

Fix: Lower temp by 10–20°C, divide food into smaller portions, use fan mode for even heat

3. How to Reset the Oven

Turn off the oven using the main switch.

Unplug for at least 10 minutes.

Plug in and restart by selecting your program again.

4. When to Call for Warranty Service

Sparks or burning smell coming from the oven.
