How to Fix E90 Error (Step-by-Step)

Unplug the dryer from the power source for at least 5 minutes to allow the electronics to reset.
Remove the top panel of the dryer to access the main control board.
Visually inspect the control board for any signs of damage, such as burn marks or loose connections.
Carefully check the wiring between the control board and the user interface, ensuring all connections are secure.
If a connection is loose, reseat it firmly. If damage is visible, the control board will likely need to be replaced.
Reassemble the dryer and plug it back in to see if the error is cleared.
Turn the appliance off, wait about 2 minutes, then turn it back on.
