ECM27CU Error Message

I have the ECM27CU motor and it has been working flawlessly since I got it installed over a month ago.  I am now in the middle of Hurricane Harvey and I need to constantly drain water from my pool.  If the pump is running, I have to turn the pump rotary switch to the off position so that I can turn the multiport valve to the drain position.  Then I turn the pump switch to the "run" position and hit the "override high" button to force the pump to run on "high" for about 15 minutes.  Then I turn the rotary switch back to "off", reposition the multiport valve to its normal position and turn the pump switch back to "run" for normal scheduled operation.  I just went out to the pump to perform the above process to once again drain the pool.  When I press the "over-ride high" button, the digital display says "invalid key move knob to motor run position for override".  IT IS IN THE RUN POSITION.  I have tried turning off the power for several minutes in case the digital interface needed to be reset, but it still does this.  Any ideas??  Thanks

I am posting a response to my own message because I found the problem.  It dawned on me after writing my post that every time I flip open the lid on the control panel to switch the pump to "off" it has been during a torrential rain and water might be getting into the control unit.  I managed, with the help of my son holding a large patio umbrella over me, to remove the control interface and took it inside the house to inspect it.  Sure enough there were about 4 drops of water around the rotary switch.  I dried everything off with a towel and re-assembled everything carefully.  Re-installed and it is once again working flawlessly.  I will be mounting the interface inside my cabana and running a longer wire to the pump to prevent any harm to the interface in the future.  I hope I saved someone a problem with my post.  All in all, I love this pump motor.
