Maintaining a Warewasher

Here are four steps fioodservice operators can take to help their machines have long and productive service lives.

It is recommended that warewashers be cleaned after every shift to remove accumulated soil in the machine.

Good operating practices start with cleaning the interior of the machine. This typically involves:

  • Removing and cleaning scrap screens, wash arms and rinse arms
  • Cleaning the wash tanks using a low-pressure spray
  • Deliming on a regular basis, with frequency dependent on water quality
  • Following the manufacturer's recommended cleaning schedule, which should be adjusted based on usage and water quality
Beyond cleaning, many manufacturers will often recommend a periodic maintenance schedule, which again varies from machine to machine and amongst the manufacturers.
