Common hob problems Q&A

The most common hob issues I encounter are cooking zones that don't heat properly, uneven heating, induction hobs failing to detect cookware, error messages and damaged glass surfaces. In many cases, the cause is related to cookware compatibility, settings or normal wear over time. However, some problems can indicate a technical fault that requires professional inspection.
If a hob isn't heating properly, the cause can vary depending on the type of appliance. On induction hobs, it may be related to cookware detection, while ceramic or radiant hobs may have an issue with the heating element itself. If one cooking zone consistently struggles to heat or takes much longer than usual, it's a sign that the appliance should be checked.
This is one of the most common questions I receive about induction hobs. The first thing to check is whether the cookware is induction-compatible and correctly positioned on the cooking zone. If the pan is suitable and the hob still doesn't detect it, there could be an issue with the pan detection system that requires professional diagnosis.
Error codes are designed to alert you when the hob detects a condition that may affect safety or performance. In some cases, the issue can be related to overheating, cookware compatibility or ventilation around the appliance. If the same error code continues to appear after following the guidance in the user manual, professional diagnosis may be required.
Uneven heating can sometimes be caused by cookware that doesn't sit flat on the surface or by a hob that isn't completely level. However, it can also indicate a problem with a heating element or another zone-specific component. If you regularly notice inconsistent cooking results from the same zone, it's worth having the appliance inspected.
Many people are surprised to learn that some noise is completely normal with induction cooking. Depending on the cookware, power level and cooking zone being used, you may hear humming, buzzing or clicking sounds. These noises are usually related to the interaction between the cookware and the electromagnetic field. However, if the sound suddenly becomes much louder than normal or is accompanied by performance issues, it's worth having the hob checked.
If the glass surface is cracked, stop using the hob immediately. Even a small crack can affect the safe operation of the appliance and may create an electrical safety risk. Avoid using the affected area and arrange professional service as soon as possible. This is not a problem that should be ignored or temporarily worked around.

Maintain, repair or replace

Should I repair or replace my hob?

That depends on the age, condition and overall performance of the appliance. If the issue is limited to a single cooking zone or component, a repair is often the most sensible option. However, if several functions are affected or the appliance has recurring faults, replacement may be worth considering. A technician can help determine which option provides the best long-term value.

What maintenance should I do regularly?

Regular cleaning is one of the best ways to keep a hob performing well and looking its best. I recommend removing spills as soon as it's safe to do so, using cleaning products suitable for the surface and making sure cookware is appropriate for your hob type. Taking care of the glass and avoiding impacts can also help prevent unnecessary damage.

DYI or professional repair

Is it safe to repair a hob yourself?

Basic cleaning and user maintenance are generally safe, but repairs involving electrical components, glass replacement or internal parts should always be left to a qualified technician. Hobs are safety-critical appliances, and attempting complex repairs without the proper expertise can create additional risks. If you're unsure, it's always best to seek professional support.

When should I book a repair for my hob?

I recommend arranging service if a cooking zone stops working, the hob repeatedly fails to detect cookware, error messages appear regularly or heating performance becomes inconsistent. You should also seek immediate assistance if the glass is cracked, you notice electrical issues, sparks or burning smells. Early attention can often prevent a minor fault from developing into a larger problem.

Final advice from the expert

If your hob starts behaving differently, don't ignore the signs. Whether it's a cooking zone that won't heat properly, cookware that isn't being detected or unusual noises during cooking, small changes in performance are often early warnings that something needs attention. Acting early and maintaining the appliance properly can help keep it safe, reliable and efficient for years to come.
