WARNING This operation requires the top cover to be removed while power is connected to the unit. use caution when performing this procedure.

NoteThe door will automatically close before the water pump will begin to run.

NoteThe pump should discharge approximately 3.25 ounces water every five seconds.

To turn current flow to dry heater ON / OFF... Press the <START> button. When the dry heater LED is... ON - the PC board is supplying current to that dry heater. OFF - there is no current to dry heater.

To verify proper operation... When the dry heater LED turns off (after approx. 15 seconds), press the <STOP> button to advance to the Temperature Display Screen. The temperature of the dry heater #1 is shown as "DH1". If the display does not reflect an increase in temperature, perform the dry heater Voltage Test below.

dry heater Voltage Test A) Disconnect dry heater harness from PC board (J7 / J8). B) Press <START> button so that dry heater LED is ON. C) Set meter to read VAC. D) Place meter probes on top two pins of J7 or J8 on PC board. If meter reading shows...• Line voltage and voltage drops to zero after 15 seconds: PC board is OK. (Perform dry heater Resistance Test on following page).

• No voltage or voltage doesn't drop to zero after 15 seconds: Replace PC board.
