E1 error code
Which appliance is showing it?
E1 is the most common appliance code of all, and it means something different on each type of appliance. On a washing machine it's about water coming in; on an air conditioner it's about the two units talking to each other.
What E1 means on each appliance
The short version for each one, and the first things to check. The full guide has every step.
On a washing machine: not filling with water
The machine couldn't get water in, or couldn't reach the right level in the time it allows. It's nearly always a supply problem rather than a broken machine.
Check first: Open the tap fully; check the fill hose; clean the inlet filter.
On a dishwasher: not filling with water
The dishwasher isn't filling properly, usually because the water inlet valve is blocked or has failed.
Check first: Open the supply tap fully; check the inlet hose; check the inlet valve filter.
On an air conditioner: indoor and outdoor units can't communicate
A communication fault between the indoor and outdoor units: the two halves of the system can't talk to each other.
Check first: Reset at the breaker; look, don't touch.
On a tumble dryer: temperature sensor (thermistor)
A dirty or failed thermistor, the sensor that tells the dryer how hot the air is.
Check first: Unplug the dryer; clean the thermistor; try again.
On a fridge or freezer: temperature sensor fault
A thermistor fault: the temperature sensor isn't reading correctly, so the fridge can't regulate itself.
Check first: Check it's still cooling; test the sensor.
On an air fryer: temperature sensor fault
A temperature sensor fault. Cosori's manual, for example, lists E1 as an open circuit in the temperature sensor.
Check first: Unplug it for 15 minutes.
On a brand-name appliance?
Big brands use their own codes for the same faults. If your appliance is one of these, its own page is more precise.
- Frigidaire washing machines use E1 for their own code: E1 slow fill or no water.
- Some Samsung washing machines show E1 instead of 4E: not filling with water.
- Some LG dishwashers show E1 instead of AE: leak detected in the base.
- Some LG air conditioners show E1 instead of CH02: indoor coil (pipe) sensor fault.
- Some Daikin heat pumps show E1 instead of E1-00: outdoor unit circuit board fault.
- Some Mitsubishi heat pumps show E1 instead of E0-E5: remote controller communication fault.
