Gas hobs are reliable and widely used in kitchens across the UK, but they can develop faults that affect safety and performance. Knowing the most common issues and simple checks can help prevent accidents and keep your hob working efficiently. With over 50 years of experience, Glotech Repairs helps homes get their gas hobs back to full working order safely and quickly.
1. Burners won’t ignite
If the flame doesn’t light, this may be caused by clogged burner ports, faulty ignition electrodes, or gas supply issues. Cleaning the burners and checking that the gas is turned on can sometimes resolve the problem.
2. Weak or uneven flame
A flame that is too low or uneven often indicates blocked burner holes, low gas pressure, or faulty valves. Regular cleaning and inspection can prevent this issue.
3. Clicking or sparking issues
Continuous clicking when trying to ignite can be caused by wet electrodes, misaligned burners, or faulty ignition switches. Drying and repositioning the parts can sometimes help, but persistent issues require professional attention.
4. Gas smell or leak
Any gas smell should be treated seriously. Check connections and ensure all valves are closed. If the smell persists, turn off the gas supply and contact a qualified engineer immediately.
5. Hob not turning off properly
If a burner won’t turn off, it may be due to a faulty gas valve or control knob. This is a safety concern and should be addressed by a professional engineer without delay.
If these steps don’t solve the problem, arranging a visit from a qualified engineer is the safest way to restore safe and efficient operation.

Good afternoon,
Thank you for your message regarding your Boffi BB40TC gas hob in SW1X, London. If one burner will not ignite, this is often caused by debris around the ignition electrode, a misaligned burner cap, or moisture affecting the spark. You can try carefully cleaning the burner parts and ensuring everything is completely dry and correctly seated before testing.
If the burner still does not ignite, it will need professional attention. Please book a repair with us so one of our engineers can safely diagnose and fix the issue.
Best regards,
Glotech Repairs.
