Maybe your brand is one of these.

Hello,

The FO error codes means that a button on the touchpad has shorted out and teh touchpad needs to be replaced. In some cases you will get that error code because the ribbon cable on the touchpad hasa loose connection at the clock. check that the connection is tight.
The error code can be cleared by pushing the clear/off button,if it returns the touchpad will need to be replaced.

1) BOSCH website shows error codes.
FO does not appear:

2) I do not see FO error code listed on Internet search
Other FO questions at fixya seem to have no answer:

3) At this point, I would suggest calling a service technician.
While waiting for service, read manual cover to cover several times.

4) Your manual is valuable resource, and shows the word 'maintenance' and 'troubleshoot' frequently.
Tankless are maintenance heavy, and should be de-limed each year.
U-tube search "delime tankless water heater."

5) Also explore Bosch website for your manual and other valuable information.

6) When service tech arrives, ask that person for tips and tricks about your unit that will help you maintain your water heater.

7) All costs are energy. Install DIY tank-type gas water heater and avoid the whole headache.

I have never seen this error code on a sharp FO 5700 are you sure that is the right model # or error code. I even did a search in the FO5700 service manual(no luck). I believe I have seen this code before on a sharp copier.

The F0 usually means that there is a problem with the keypad.
My solution for the F7 problem may help. You will find my solution at the following link.
