TROUBLESHOOTING THE AUTOFILL SYSTEM

Verify that unit is connected to the water supply and that water supply is turned on.

Drain the water in the cookpot to a level below the upper water-level sensor.

Place the master ON/OFF switch

in the ON position.

Press the computer ON/OFF

switch.

check connections and wiring to

 

 

 

 

 

 

 

 

solenoid valve. If wiring and

 

 

 

 

 

 

 

 

connections are intact, the valve

Yes

 

 

 

 

 

 

 

 

Check sensor and wiring. If they are NOT grounded, the computer has failed.

No Replace.

If they ARE grounded, repair

or replace as required.

Check resistance through Pins 2 and 9 of the computer 15-pin connector. If it is less than 1 ohm, the computer has failed.

No Replace.

If it is 1 ohm or greater, repair wiring between sensor and computer or replace

sensor as required.

Autofill system is OK.
