Problem w/ my Woodmaster 5500 OWB

Hoping I might find an expert here to gleen some insight from. My Woodmaster 5500 is having a P1 fault that I can't reset. Manual isn't the best in explaining the issue. The P1 fault is there and the water level light isn't lighting.
I refilled (light had went out) along w/ bleeding the air from the system while filling. Light still won't come on.
Is this a sure sign the probe or the connection to the probe is bad? Comments / suggestions would be greatly appreciated. Of course sunday's aren't the best time to get ahold of my dealer.
Thanks for any help that can be provided!
