How do you read a code without guessing?
A code names the circuit that tripped, not the part to buy. The same two letters can mean different things across brands, and even across product lines from one maker: Wolf's F1 is a door lock on one oven and a food probe on another. So match the brand, then the appliance, then the code. The meanings below come from each manufacturer's own support pages.

Which codes mean stop using it now?
- Any leak code on a dishwasher (Thermador E15, Samsung LC or LE): close the valve under the sink.
- Compressor codes on a fridge full of food: keep the doors shut and call early.
- Oven overheating or sensor codes: leave the oven off.
