"Took quick pics, found unit running in a safety loop. Found control has 1-1 internal board error and 3-1 pressure sensor error. Cleared codes and as soon as I turned knob it started safety loop again. When that finished I checked pressure hose for kinks or blockages and it is open and clear. I put into diagnostic cycle and it ran that and finished, immediately when it was done got stuck back into safety loop And repeats the 1-1 and 3-1 codes. Installed parts unit checks ok"
