# The Ecolet 25e or 65e mixing arms are not turning

The mixing arm moves very slowly and the seat sensor will stop it from moving when you lift the toilet seat lid; this means that you won’t actually see it moving unless you look for it. Try the following steps to check if the mixing arm is moving:

1. Lift the toilet seat up to activate the seat sensor (this is the magnet in the seat lid triggering the relay in the toilet top)
2. Make sure you can see into the composting chamber; you’ll need to depress the toilet seat for the 25e or lift it for the 65e to move the chamber screen
3. Now move the toilet seat lid away from the unit top to release the seat sensor
4. You should see the mixing arm start its rotation.

If you don’t you’ll want to start troubleshooting:

- Check that your lid has a magnet
- Use a paperclip or a fridge magnet over the lid to test
- Can you hear the mixer motor? 
    - If you can hear the motor and there is still no rotation, check the shear pin
