BOSH oven doesn’t work properly because of function error E218

The E218 error indicates a problem with the lower cooling fan. The fan could be moving too slowly or too fast. There may be something blocking the fan or a damaged wire providing the wrong feedback to the control board.

You can try resetting the error by disconnecting the power for 5 minutes or so. Turning off the power with the appropriate circuit breaker is the easiest option. Then check what happens when you start the oven again. If the problem recurs, then you need to check the wiring and for anything interfering with the fan circulation. The Hall Effect sensor should also be checked. Most often the fan needs to be replaced.

Please add a comment with the model number of the appliance for specifics for your oven.

I hope this helps.
