The boiler was leaking on this kettle as is shown by the white lines; it was not noticed until after the damage caused the kettle to short out.

The item was down for three days, during which time the customer could not serve soup.

This is a boiler from an espresso machine that has been filled with lime buildup. It cost over $3,000.00 to correct the problem, which preventative maintenance would have prevented.

In an HVAC unit, a fan draws air across a filter. The blower has to work harder and more frequently to draw air across a dirty filter and consequently puts more strain on the parts and uses more energy. Proper filter changes and lubrication could have prevented the breakdown seen above.
