Dishwasher Performance

[jmont]

Does anyone have a good method of checking the force of the water spraying on the dishes?  Being that it is not possible to see inside the cabinent during operation I am contemplating using a piece of plexiglass to cover the door opening to get a better idea of what is going on.  Does anyone have any comments or suggestions on this subject?   I understand that water level, water temperature and other things determine how well the dishes are cleaned but getting a good handle on how good the pump is without actually changing it out seems to be a problem.
