An induction cooktop that won’t heat is almost always caused by one of three things: incompatible cookware (not magnetic enough), a single failed zone (induction coil or board fault for that zone), or a completely dead cooktop (main induction control board failure). Start with the fridge magnet test
The E0 code (or flashing –) on an induction cooktop means the zone cannot detect suitable cookware. The pan base is either not magnetic, too small for the zone, off-centre, or severely warped. Place a fridge magnet on the base of your pan — if it falls off or barely clings, the cookware is th
Westinghouse, Chef and Electrolux ovens share the same Electrolux-platform electronics. The most common fault codes are F2 (temperature sensor short circuit) and F3 (temperature sensor open circuit) — both mean the NTC probe inside the oven cavity has failed. A replacement NTC sensor costs $15
Technika is a house brand (sold through Aldi and other retailers) and its fault codes are not comprehensively documented in publicly available service literature. If your Technika oven displays an error code, the underlying cause is almost always a temperature sensor failure, a burnt-out fan-forced
Omega freestanding ovens (Italian-platform designs) show “E” codes when a sensor or fan fault is detected. E1 is the most common — it means the oven temperature sensor (NTC probe) has failed or is reading incorrectly. A replacement Omega fan-forced element to restore heating costs
Fisher & Paykel ovens show “F” codes when a sensor or control fault is detected. The most frequent fault across the range is a temperature sensor (NTC probe) failure — the oven cannot read the cavity temperature and shuts down heating as a safety measure. A replacement fan-forc
Bosch ovens display “E” codes (sometimes shown as “Err”) when the control system detects a fault it cannot self-recover from. The most common causes across all Bosch oven generations are a temperature sensor failure (the probe inside the oven cavity), a door lock fault on pyr
The Samsung UE error code (also shown as Ub on some models) means the drum load is unbalanced and the machine has stopped to protect itself. Open the door, redistribute the washing and restart — this fixes it most of the time. If UE keeps coming back on well-spread loads, worn shock absorbers
The Samsung tE error code (temperature error) means the control board cannot get a valid reading from the water temperature sensor (NTC thermistor) or the heater element circuit. A faulty thermistor is the most common culprit; a failed heater element runs a close second. A replacement Samsung heater
The Samsung LE error code means the machine’s leakage sensor (a float switch in the base tray) has detected water underneath the drum. The most common cause on front loaders is a damaged or perished door boot seal, but a loose drain hose, blocked detergent drawer or oversudsing can also trigger it.
