🔧 Oil Dripping From Kitchen Chimney? 5-Minute Fix

🎯 Quick Answer

Problem: Oil dripping from kitchen chimney onto hob or floor?

Most Common Cause: Saturated baffle/mesh filters that need immediate cleaning (90% of cases). Other causes: overfilled oil tray (auto-clean chimneys), wrong tilt angle, or poor duct installation.

Quick Fix (5 minutes):

  1. Switch off and unplug chimney
  2. Remove and soak filters in hot water + dish soap + baking soda (30 min)
  3. Empty oil collection tray if you have auto-clean model
  4. Check chimney is level (oil should drain to tray, not backwards)
  5. Scrub filters, dry completely, reinstall
⚠️

Problem Overview

Sticky oil dripping from the kitchen chimney or falling back on the hob usually points to filter saturation or ducting/installation issues. This happens with all brands (Faber, Elica, Glen, Hindware, etc.). Use this checklist to fix it fast.

Safety First

  • !
    Switch off appliances: Switch off the chimney and hob before cleaning to prevent accidents.
  • !
    Wear protection: Wear gloves as degreasers can irritate skin. Unplug if you will remove filters or clean inside.

🔍 Quick Checks ⏱️ 5 minutes

1 Filter Saturation

Baffle/mesh filters look brown or blocked? If yes, clean immediately.

2 Oil Collector Tray

For auto-clean models: Is the tray full? Empty and wipe clean.

3 Chimney Tilt & Level

Ensure the unit is level; oil should drain into the tray, not back to the hob.

4 Duct Slope

Maintain a slight upward slope from hood to outside; avoid dips where oil condenses.

5 Duct Length & Bends

Keep ≤2–3 bends; excessive length/bends cause vapour condensation.

6 Cowl/Rain-cap Outside

Ensure it's present and clean to prevent back-drip from outside.

🛠️ DIY Fixes You Can Do Now

1

Clean Filters

Soak filters in hot water + dish soap + a spoon of baking soda for 30-40 minutes. Scrub thoroughly, rinse, and dry completely before reinstalling.

💡 Pro Tip: For heavy grease, use a degreaser or vinegar solution for better results.

2

Auto-clean Cycle

Run the auto-clean cycle as per manual instructions. Empty and clean the oil tray after each cycle.

💡 Pro Tip: Run auto-clean weekly for heavy frying, bi-weekly for normal cooking.

3

Seal Gaps

Check and reseal all duct joints with aluminum tape to prevent leaks and oil seepage.

4

Adjust Suction Speed

Use lower speed for simmering, high only for frying/tadka. This prevents excessive oil vapor collection.

💡 Installation Issues (Call Installer)

Wrong Height

Chimney too high or low from hob

Solution

Ideal: 24-30 inches above hob (check manual)

Incorrect Tilt

Oil draining backwards

Solution

Adjust so oil drains forward to tray

Ducting Issues

Too many bends or wrong material

Solution

Use 6-inch smooth metal duct, reduce bends

Heavy Build-up

Motor & housing need cleaning

Solution

Professional service required

🛡️ Maintenance Schedule for Indian Cooking

📅

Baffle Filter

Clean every 2-4 weeks for heavy frying

🔄

Oil Tray

Empty every 1-2 weeks (auto-clean models)

⚠️

Deep Service

Professional cleaning every 6-12 months

💡 Tip for Heavy Frying: Prefer baffle filters over mesh filters and ensure correct ducting. Regular cleaning prevents oil pooling and dripping.

📞 When to Call a Professional

🔧 Installation Issues

  • • Chimney height adjustment needed
  • • Ducting needs reconfiguration
  • • Tilt/level correction required
  • • Outdoor cowl installation

Service Required

  • • Motor making unusual noise
  • • Heavy grease build-up inside
  • • Auto-clean function not working
  • • Persistent oil dripping after cleaning

⚠️ Disclaimer: This guide is for basic maintenance only. For electrical issues or major repairs, always consult authorized service centers. Regular maintenance extends chimney life and ensures kitchen safety.

❓ Frequently Asked Questions

Q: Why is oil dripping from my kitchen chimney even after cleaning filters?

A:

If filters are clean but oil still drips, check: (1) Chimney tilt - ensure it's level so oil drains to tray, not backwards; (2) Oil collection tray - empty it if full; (3) Duct installation - ensure upward slope with no dips where oil pools; (4) Motor housing - may need professional cleaning if heavily clogged. Also verify filter is completely dry before reinstalling.

Q: How often should I clean chimney filters to prevent oil dripping?

A:

Heavy frying (Indian tadka/deep frying): Clean filters every 2-3 weeks. Moderate cooking: Every 4-6 weeks. Light cooking: Every 2-3 months. For auto-clean chimneys, run the auto-clean cycle weekly for heavy use, bi-weekly for moderate. Empty oil tray after each auto-clean cycle. Saturated filters are the #1 cause of oil dripping.

Q: What is the best way to clean baffle filters at home?

A:

Best method: Soak filters in hot water + 2-3 spoons dish soap + 1 spoon baking soda for 30-40 minutes. Scrub with stiff brush, rinse thoroughly, air dry completely (4-6 hours or overnight). For stubborn grease: Add vinegar or use commercial degreaser. Never: Put filters in dishwasher (damages coating), use abrasive scrubbers (scratches surface), or reinstall while wet (causes dripping and electrical issues).

Q: Does oil dripping mean my chimney installation is wrong?

A:

Not always. 90% of oil dripping issues are due to filter saturation - clean filters first. However, installation issues can cause persistent dripping: (1) Wrong height from hob (should be 24-30 inches per manual); (2) Incorrect tilt causing oil to drain backwards; (3) Duct with too many bends or downward slopes; (4) Missing rain cap/cowl causing outdoor moisture backflow. If cleaning doesn't fix it, call installer to check these.

Q: Can I use my chimney while oil is dripping?

A:

No, stop using immediately. Dripping oil can: (1) Fall on open flames causing fire hazard; (2) Damage hob surface and knobs; (3) Create slip hazards on floor; (4) Worsen motor/housing grease buildup. Clean filters or empty oil tray immediately. Use chimney only after fixing the dripping issue. If urgent, cook on low flame temporarily and place newspaper under drip area until you can fix it.

Q: Is filterless/auto-clean chimney better than baffle filter to avoid dripping?

A:

Both can drip if not maintained. Auto-clean chimneys collect oil in a tray that needs regular emptying (weekly for heavy use). Filterless chimneys still have baffles that auto-clean but the tray can overflow causing drips. Traditional baffle filters need manual cleaning but give you visual feedback on saturation. Best practice: Auto-clean chimneys for convenience but empty tray regularly; baffle filters for visual control and lower cost, clean every 2-4 weeks.

Q: Should I call a technician for chimney oil dripping issue?

A:

Try DIY fixes first: Clean filters, empty oil tray, check level/tilt. This solves 90% of cases. Call technician if: (1) Dripping continues after filter cleaning; (2) Motor makes unusual noise; (3) Auto-clean function doesn't work; (4) Heavy grease buildup inside motor housing; (5) Chimney needs height/tilt adjustment; (6) Ducting reconfiguration required. Technician visit costs ₹300-800. DIY fixes save money and time.

Important Safety Reminder

If you're not comfortable with any step, or if the problem persists after trying these solutions, please contact a qualified technician. Safety should always be your first priority when dealing with electrical appliances.
