7.3.7 Replacing the Pressure Regulator or Solenoid Valve
1. Drain the cookpot and disconnect the cooker from the electrical power supply. If necessary,
reposition the cooker to allow free access to the component to be replaced. Turn off or
disconnect the water supply to the cooker. If replacing an Autofill system pressure regulator or
solenoid valve on a unit equipped with basket lifts, the basket lift upper rear panel must be
removed.
2. Loosen the compression fittings on the water lines running to and from the regulator or solenoid
valve and remove the component from the unit. (NOTE: If the solenoid valve is mounted
adjacent to the regulator, disconnect the solenoid leads and remove both the regulator and
solenoid valve from the unit.)

the replacement, using thread sealer on all connections.

connections.
