COOKER PROBLEMS (cont'd)
Water enters compartment through Steam Solenoid Valve
If the cooking cycle is on and water enters compartment through valve and
steam pressure is nonexistent, then this may indicate malfunction of the
Water Level Control (in Cabinet). The switch in the Water Level Control may
be defective and remain in the closed position, consequently energizing the
Boiler Water Supply Valve to continuously supply water to fill the Heat
Exchanger, Steam Header and eventually overflow into the compartment(s)
through Steam Solenoid Valve(s).
However, a more likely cause is excessive sealant and/or lime build up
within the chamber of the Water Level Control, which having formed around
the float, prevents it from fluctuating upwards with the increase in water
level and thus the float is unable to trip the switch in the control to de-
energize the solenoid valve and consequently stop water from being fed to
the Heat Exchanger and flooding the system. Refer to Heat Exchanger on
Removal of Sealants, etc.. This malfunction is extremely serious and
indicates that water quality is inadequate and must be rectified immediately
with a proper water conditioner.
Pressure Relief Valve leaks or opens frequently
This valve sits on top of the Steam Header and assures that pressure will
not exceed 8 p.s.i.. The valve may leak if dirt is under valve disc.
Manually trip lever of valve smartly a few times in an effort to dislodge
and blow dirt away. Pressure Gauge on Cooker Control Panel should read
maximum 6 p.s.i. and if valve continues to leak, then it is defective and
must be replaced.
Pressure in Steam Header may be too high and Pressure Regulating Valve will
require adjustment. To readjust, loosen lock nut on the adjusting screw and
turn adjusting screw counter-clockwise to decrease pressure.
