COOKER PROBLEMS
Water accumulates in bottom of compartment
Water accumulation in bottom of compartment is primarily condensed
steam and failure to drain out completely may be due to improperly
leveled appliance. Refer to Section 1, Installation Instructions.
Stainless steel compartment Screen protecting exhaust port in compartment
may be clogged with debris and screen must be removed, cleaned and
replaced. Exhaust Solenoid Valve may be obstructed with accumulated
grease which will impede drainage of water. Refer to Section 4, Periodic
Maintenance.
If grease is not the obstruction, then with power Off, the Exhaust Header
must be disconnected at all unions and removed. The Union Elbow must be
unthreaded from the Exhaust Solenoid Valve. Visually inspect the Exhaust
Header and the valve for obstruction. Verify that no obstruction is
present by passing an object, such as a pencil, freely through valve and
also examine that exhaust port (stainless steel 1/2" fitting welded to
Cooker body) is internally clean. Reconnect all plumbing.
However, the Exhaust Solenoid Valve may be incapable of opening. Since
this valve contains a moveable blade and when de-energized, the blade
reacts as a guillotine which should be free to move fully down into the
valve pocket (projection at bottom of valve) so that the pierced hole in
the blade aligns perfectly with the body opening. If debris has
accumulated in the bottom of the valve pocket, then blade obviously will
be impeded from moving into pocket completely. Further, a burnt out valve
coil is likely. With valve removed from Cooker body, remove retaining
clip at top of solenoid. Grasp (green) cover and housing intact with coil
inside and slide off from valve. Unscrew projecting tube from top of valve
body and remove internal mechanism together with blade assembly. Next
unscrew both assembly bolts and split brass body of valve removing loose
internal parts. Now flush and clean pocket thoroughly. Reassemble all
parts in reverse order of disassembly. Energize valve with 120 V power to
verify that valve is functional. As mentioned, coil may require
replacement. Reconnect all plumbing.
Compartment remains pressurized at end of cooking cycle
As noted, when water accumulates at bottom of compartment, an obstructed
Exhaust Solenoid Valve must be cleansed to allow not only water but also
pressurized steam to exhaust at end of cooking cycle.
