WATER SYSTEM CHECKLIST
A water-related problem often causes the same
symptoms as a refrigeration system component
malfunction.
Example: A water dump valve leaking during the
freeze cycle, a system low on charge, and a starving
TXV have similar symptoms.
Water system problems must be identified and
eliminated prior to replacing refrigeration
components.
Possible Problem
Water area (evaporator)
is dirty
Water inlet pressure not
between 20 and 80 psi
Incoming water
temperature is not
between 35°F (1.7°C) and
90°F (32.2°C).
Water filtration is plugged
(if used)
Water dump valve
leaking during the freeze
cycle
Vent tube is not installed
on water outlet drain
Hoses, fittings, etc., are
leaking water
Float valve is stuck open
or out of adjustment
Water is spraying out of
the sump trough area
Uneven water flow across
the evaporator
Water is freezing behind
the evaporator
Plastic extrusions and
gaskets are not secured
to the evaporator
Water does not flow over
the evaporator (not
trickle) immediately after
the prechill
