15. MAINTENANCE

Periodically, the drain screen in tank will have to be removed and cleaned. The
accumulated lint and debris could slow down the draining enough so tank will
not be emptied of cleaning solution when rinse cycle begins.
Once a month, open power module and vacuum any dust that might have been
drawn in by the fan. Never operate unit with cover of power module off.
The tank is manufactured of 316SS and the modules of 304SS. Clean with a
commercially available cleaner for stainless steel kitchen appliances.

16. TROUBLE SHOOTING
• If there seems to be erratic behavior with a component, or if the fill
and/or clean cycle seem to have changed, always go through the
following procedure:
o Turn RUN-STOP switch momentarily to STOP and then back to
RUN. The program will now clear and revert to the beginning
calling for a FILL CYCLE. Move FILL-CLEAN switch to FILL and
push START regardless of if the tank has water in it.
o If the problem persists, continue with trouble shooting or call
manufacturer.
• If there is still a problem, look at the PLC located in the Power module.
With MAIN switch ON and RUN-STOP in RUN position. Make sure that
the POWER and RUN lights are ON.
