The only thing you can check is the pressure tube. Power off at wall, open panel & locate tube on right hand side connected to control module. Remove tube from module and blow down it to clear any obstruction. Trim about 5-6 mm off end of tube and push it back on to module, make sure it has a securing clip to hold it. Then check other end of tube where it goes on to the outside of the plastic bowl. Make sure that end is also tightly connected. Run & try machine. If fault still exists then the pressure sensor will be faulty. That is part of the main control board and will mean you have to buy and fit a new board.
