Hob Error Code: What It Means and How to Fix It

When your hob error code, a digital alert shown on electric or induction hobs when something goes wrong. Also known as cooker fault code, it’s your appliance’s way of saying, "Hey, something’s off—and I need help." These codes aren’t random. They’re specific signals tied to real problems: a faulty sensor, a broken power module, or even just a dirty surface. Ignoring them won’t make them disappear. In fact, they often get worse—leading to bigger repair bills or a full replacement.

Most induction hob, a modern cooking surface that uses magnetic fields to heat pots directly error codes like E1, E2, E5, or U1 point to common issues: overheating, power surges, or failed temperature sensors. For example, an E1 code usually means the hob’s internal temperature is too high—often because ventilation is blocked or the cooling fan is stuck. An E5 might mean the power supply is unstable, which can happen after a storm or if your kitchen wiring is old. You don’t need to be an electrician to check these. Unplug the hob for 10 minutes, clean the vents, and see if the code resets. If it comes back, you’re looking at a hardware fault. The oven control board, the brain of your cooking appliance that manages power and settings is often the culprit, especially in units over 5 years old. Replacing it can cost half as much as buying a new hob, and it’s a fix we see often in Northampton homes.

Some codes are simple. A flashing "H" might just mean the surface is still hot after use—no repair needed. But if you see a code that doesn’t match your manual, or if the hob turns off mid-cook, that’s not normal. Many people panic and call for a full replacement, but over 60% of hob error codes are fixable with a simple part swap or reset. You’ll find real stories below—from someone who fixed an E2 code with a $15 sensor to another who saved $800 by diagnosing a faulty power relay before calling a technician. These aren’t theory. These are fixes done right here in Northampton.
