p/f message---cycle stops
 

The machine stops after about five minutes operation on all cycles.
Message P F shows & machine will only start at the beginning of another cycle. THANKS!!! John

Hi snuffydog

Most likely the problem with your dishwasher is a bad control board.
If the dishwasher is less then five years old then the control board is probably under limited manufacturer warranty (the first digit after "TH" represents the year and the second and third digits - the number of the weak the dishwasher made).
If it's more then five years old and you would like to fix it yourself:

- The part number for the new control board AP3965290

Good luck.
Gene.
