7.Reattach the 12-pin connector to the interface board, close the control panel, and replace the two screws removed in Step 2.

7.3.7Replacing 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.)

3.If replacing a regulator, adjust the replacement regulator output pressure to not more than 40 PSI (28.15 kg/cm2) before installation in the cooker.

4.Recover the fittings from the failed component (regulator or solenoid valve) and install them on the replacement, using thread sealer on all connections.

5.Reverse Steps 1 and 2 to complete the procedure, being sure to apply thread sealer to all connections.
