Why do we need to monitor the pressure gauge on a dishmachine?

Dishmachines are to operate at specific water flow pressures. Water flow pressure can greatly effect how well a dishmachine will sanitize. Low water flow pressure results in inadequate spray patterns and incomplete coverage of the equipment and utensils being washed. Excessive flow pressures will atomize water droplets and result in incomplete coverage.

A pressure gauge must be installed on the dishmachine's final rinse line so workers can monitor the water flow pressure a dishmachine. The target operating pressure should be listed on the data plate that is attached to the dishmachine. If the data plate is missing, check the equipment manual to determine the proper operating pressure.

Workers must check the pressure each day before cleaning and sanitizing anything in the dishmachine. If the pressure is not correct, then all dishes must be manually washed in a three-compartment sink until the dishmachine is repaired.
