(3) Inspect the internal valve parts for damage or excessive wear. Clean all
parts during the inspection.
Check for a faulty control circuit.
(a) Energize the solenoid. Ensure there is a metallic click which
indicates the solenoid is operating. If there is no click, there is a loss of power supply.
You may not hear the click due to the wall between the control and solenoid,
noise from other sterilizers, etc. If you do not hear the click, check the
solenoid by placing a small screwdriver on top to see if it is magnetized. If it
is magnetized, the coil is conducting, and the solenoid is energized.
(b) Check for loose or blown out fuses, an open-circuit or grounded
coil, broken lead wires, or spliced connections.
(5) Check for a burned-out or open-circuited coil (refer to the procedures for
checking the solenoid in the NOTE above). Replace the coil if necessary.
(6) Check the voltage across the coil leads. The voltage must be at least 85
percent of the nameplate rating.
(7) Check the pressure to the valve to ensure it is within the range specified
on the nameplate.
(8) Check for damaged or worn valve parts which could cause excessive
leakage. Disassemble the valve and clean all parts. Replace the parts that are worn or
Check the plumbing for leaks.
(10) Check the steam traps for clogs and damage.
(11) Inspect the door gasket for nicks or tears.
(12) Check the chamber drain screen for clogs or damage.
(13) Check the air filter for cleanliness and serviceability.
