Low Water Sensor Not
Satisfied (Autofill) FIG 3.1A
Water Sensors are stainless steel studs circled
by white teflon and are located inside cooking
chamber on left hand wall towards unit front.
Water sensors must be kept thoroughly clean. This
should always be the first step with any alarm
Water Level Board (Autofill) FIG
3.1B
An LED light on D3 will flash based on water level.
Single second intervals indicate the water level
board does not sense water
A three second interval indicated the water level
board is satisfied with the water level to allow for
heating.
If the indicator light is flashing on a single second
interval - the water board should close the K1 relay
which provide power to the autofill solenoid valve
and allow the unit to fill
If unit is not filling remove the blue wire from J6
and the brown wire from J5. Test for AC voltage
across the wires. FIG 3.1.C
If AC voltage is present, connect the two wires
together using a jumper wire. If the unit fills with
the jumper in place - replace the water board.
If the unit does not fill after bypassing the board,
proceed to Auto-fill Solenoid.
If voltage is not present, see below
Control Board Unplug the unit whenever disconnecting wires for
the main control board.
Disconnect the tan wire from J7-3 and the brown
wire from J7-4. Connect the two wires using a
jumper wire. Reconnect the unit to supply power.
If contactor engages with board bypassed, main
control board should be replaced.
Autofill Solenoid Valve FIG 3.1D Remove wires from the solenoid and test for
24VAC. If voltage is present, replace valve.
If there is no voltage, see above to troubleshoot
water board.
