I don't mind you asking at all, the answer being that the E10 error is associated not only with a filling problem but also a Pressure Switch
problem. That's where the sump hose comes into the frame as it is directly linked to the pressure switch system.
Elaborating yet further, if the sump hose is blocked to the pump then the chances are it with throw up an E20 error. If the pressure chamber attached to the sump hose
is blocked or has an air leak then it, albeit very occasionally, will throw up an E10 error.
I hope that helps you further toward a swift conclusion to your problem.
