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 Mater 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
Boiler, Steam Header and eventually overflow into the compartments) 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
Boiler and flooding the system. Refer to Boiler 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 re-adjust, loosen lock nut on the adjusting screw and turn adjusting screw
counter-clockwise to decrease pressure.
