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.

tried to take off the drain hose, but could not get it off the back, only by the disposal. I turned if off and on about 6 times and ran the delime cycle with lots of limeaway. It got the E5 error on the delime cycle, but it worked the next time I tried to run it.
The manual does say to turn it off and on as it drains out the water. Takes a while as it has to heat up the water each time.

SOURCE: I have a PD code
PD is not an error code. It shows that when it draining water out shortly after power-up and when shutting down. If it seems to be showing "PD" longer than usual, it means the dishwasher's control circuitry believes there is still water in the tank, due to a faulty water level probe, most like the one under the lift-out screen. It has a plastic body with a metal probe coming out the center.
There is also a dual probe at the rear of the machine, but I believe the dishwasher uses the front probe to determine when to stop draining the machine during "PD" - most likely meaning "Power Drain" or "Power Draining".
If you are not seeing any E- codes (E1, E2, E3, etc.) then these water level probes are likely just fine and the "PD" is appearing normally, as it should during draining conditions.
