PREVENTIVE MAINTENANCE FOR LVO PAN WASHERS
Turn off power and drain machine, making sure it drains freely.
Check machine for general cleanliness. Make sure the pump screen and scrap trays are clean and properly in place.
Wash heating elements (electric models only) must be cleaned on a daily basis for proper operation. Check for plugged
wash and rinse nozzles. Check if all cleanout plugs are in place at the ends of the rotating wash arms and make sure they
are not cracked or broken. If necessary, the entire wash arm assembly can be removed by pulling out the grip ring pin and
sliding the assembly out of the hub. These items are part of the daily maintenance schedule and should be done on a daily
basis.
Check for excessive play in the hub/wash arm assemblies. Excessive wear can affect the wash pressure and shorten
the life of some hub components. Basic and complete hub repair kits are available from the factory.
Close drain valve and fill machine, making sure drain does not leak (some water may initially run out the drain
through the overflow). Run through a Light, Medium, and Heavy wash cycle, checking for proper timer operation.
Machines prior to 1997 may have a single adjustable wash timer in place of the three-position selector.
Check if Power “ON”, Wash, and Rinse lights are working.
Check if pump pressure during wash cycle is within recommended range (See owners manual or legend on gauge
panel).
Check if rinse pressure is approximately 20 psi. Note: This must be checked during rinse cycle only for accurate
reading.
Make sure steam exhaust fan is working properly. On machines with a 100cfm Tjernlund fan, the fan should run
continuously when power switch is turned on. On machines with a 700 cfm American fan, the fan should run for set
amount of time after the rinse cycle.
Allow machine to heat up to recommended temperatures, noting if temp gauges and thermostats are operating
properly (see start up procedure in owners manual for approximate heat up times). Wash temperature and Rinse Tank
temperature should be noted at this time. The rinse water temperature gauge is accurate only during rinse cycle and should
be checked while machine is rinsing.
Note: If a qualified technician is available, current readings for heating elements should be taken to ensure they are
heating properly.
On machines with slide-up doors, door cables and connections should be inspected for damage or excessive wear and
replaced if necessary. Make sure cable pulleys turn freely and door switch is still adjusted properly.
Pump motor(s) should be greased occasionally depending on usage. Once or twice yearly should be sufficient under
normal use.
Note:
> Items above marked
are easily identified visually and should be checked on a daily basis. Other items should be
checked periodically, depending on usage.
> Time required for complete inspection may vary, depending on wash timer settings, heat up time, etc. One to two hours
is a reasonable amount of time unless problems are encountered that need attention. If any problems or questions arise,
call the factory for assistance.
