Undercounter warewashers are one of the most complicated pieces of equipment in the kitchen and should be treated as such.

Undercounter warewashers have a number of components, which increases the likelihood of breakdowns and failures.

Here are a few signs that it may be time to replace an undercounter warewasher:

Increased service calls and high repair costs. Undercounter warewashers can last up to 10 years with proper maintenance. Yet, when a unit requires an increasing number of service calls or multiple component replacements, it may be nearing the end of its service life.

Signs of wear and tear. Tank leaks may signify that the welds are giving out. Also, problems can be caused by water leaking from the boosters. In either case, the warewasher may need to be retired.

Loss of controls. If the warewasher's controls do not operate properly or pump pressure is lost, replacement is most likely needed.

Inconsistent results. The results of the unit are a key indicator that the warewasher is not operating at 100 percent. If items are not being cleaned and sanitized properly, this may be an indicator that wash and/or rinse arms are wearing out.
