Replaced the control board as it was intermittent. This did not solve the issue, the pump would no longer run at all. Then I replaced the waste pump after the board replacement and this issue was resolved. This in fact fixed the machine. Water had broached the armature shaft seal and allowed the pump to run intermittently for a while after the breach. Happy to have a dishwasher again but not happy that I am the proud owner of two control boards that work now! Oh well.
