I spoke with Furrion in regards to your Furrion RV Tankless Water Heater # FR93FR, and they recommend that you attempt to blow into the tube (pictured below) to potentially clear any stoppage that could be causing this issue.

You are going to need to remove the pressure switch and disconnect the tubing to do this.

Let me know if after doing this and you're still getting the E5 error code and we can continue to troubleshoot.
