heat light is lit, ignition fail light is lit, low
water light is not lit, blower motor is ON
(high speed is default for blower if speed
control malfunctions).
1. Gas supply is OFF.
2. Transformer (1T) output voltage is low.
3. Tilting models only - Gas shut-off valve (1SOL) not receiving power
or malfunction.
4. Spark ignitor.
A. Spark probe dirty or corroded (poor spark).
B. Burner flame sense current too low - dirty or corroded probe; or
flame sense wire connection corroded.
5. Ignition module malfunction (no sparking at ignitor).
6. Gas valve malfunction.
Kettle does not heat, power light is lit,
low water light is lit, heat light is not lit,
blower motor not ON.
1. Incorrect voltage to water level control (internal circuit protects board
from voltages above 132VAC or below 108VAC). Check supply
voltage to kettle.
2. Fluid level in reservoir jacket below water level probe (LLCO). Check
fluid level in sight glass.
3. Kettle jacket was refilled incorrectly with deionized or reverse
osmosis (RO) water. Use distilled water only.

5. Water level control malfunction.
Kettle does not heat, power light is lit,
low water light is not lit, heat light is not
lit, blower motor not ON.
1. Tilting models only - Tilt switch (2S) is open: Kettle not fully upright;
or switch not adjusted properly; or switch malfunction.
2. Pressure switch (1PAS) open or malfunction (fixed, not adjustable).
3. WLC malfunction (water level ok in sight glass).
NOTE: LLCO LED is ON (probe sensing fluid).
4. Temperature sensor malfunction; potentiometer setting too low or
malfunction; or temperature controller malfunction.
5. Interconnecting wiring malfunction.
