I found this and it also may have to do with the door seals...how old is the unit...if door seals get old and stiff..(not soft and pliable) they sometimes leak...after usage the heat and moisture may cause them to swell and or become soft thereby sealing better...but this is what I found in the user manual.
Machine displays "E7" on LX30 model or "CLEAN PROBE" on LX40 model.
1. Clean water sensors inside tank.
It suggests contacting Hobart if this fails but I also found this problem is associated with fill issues...as in an E4 error...this what you do in that case....
Machine won't fill or won't fill high enough(LX18, LX30 display shows "E0," "E2," "E3," or "E4")
1.Low water pressure — check for clogged hose strainer; check that site water pressure meets minimum flow pressures.
2.Make sure probes are clean.
3.No water pressure — main water supply valves may not be working.
4.Drain valve open - turn machine off to drain machine, then on. Repeat twice (this assists in clearing any drain valve obstructions). Wait for machine to reach READY mode and press WASH. Slowly open door several seconds later and note water level. Close door; 30 seconds later, open door slowly and check that water level is the same as it was. If not, repeat the
5. Delime machine.
Good Luck and I hope this helps...let me know if it doesn't and i am sure I can get to the bottom of it...thanks for rating my effort...the Fang.

E2: Reload the paper correctly and press [Black] or [Color].
E7: The cartridges are not installed in place.
These are from the manual.
