Quick Test Mode

Test Mode:

Each Test Mode for the Squall is as follows in the coming pages. The test modes indicated by the red arrows are modes unable to get an access once the washing cycle has started due to safety resons.

Definition of Quick Test Mode:

-Check operation of all LED’s (Verify faulty LED).

-Check model and software version.

-Check different operating modes (e.g. water valve, motor, door, drain pump, etc.).

How to Enter:

-Plug in the unit.

-Press Soil Level Key + Signal Key and Power Key at the same Time.

Important. Once test mode is performed, all data including the diagnostic code saved in the EEPROM will be erased.

EEPROM Clear Check

Definition of EEPROM Clear Mode:

-EEPROM initialization.

-All course/option settings are to be reset to default values after EEPROM initialization.

-When Service arises and it needs PCB replacement, EEPROM should be reset.

How to Enter:

Continuous Run Mode:

1.Press Pre Wash + Pure Cycle 3 sec during Power On State (Normal User Mode) .

2.Once in Continuous Run Mode, The seven segments will no longer display “0000” and will alternate between displaying the number of cycles of the completed course and the remaining time of the course.

3.The Continuous Run Mode will repeat the previous cycle until continuous run mode is cancelled.

4.During Continuous Run Mode, press Pre Wash + Pure Cycle 3 seconds to return to normal user mode. The seven segments will no longer display the number of cycles and will display the maintenance time only.

5.If you exit Service Mode after entering it from Continuous Mode, the washing machine returns to Continuous Mode.

6.If power is lost in Continuous Run Mode (that is, when the power plug is disconnected or the Power key is pressed turning the washing machine off), the mode is released when the washing machine is turned on again.

Service Mode

Power On State			Signal + Delay Start			Service Mode
(Normal User Mode)			3 sec

Service Mode is canceled if no key is pressed for 5 minutes before the washer operation begins. However, this is not true when the washer operation has already started.

Definition of Service Mode:

-Service Mode enables service technicians to verify the operation of the washing machine and do troubleshooting.

-Service Mode can be entered during all washing cycle without interrupting the cycle except some of test modes.

-Various tests can be done with Service Mode. So, troubleshooting can be done based on the resulting diagnostic codes.

How to Enter:

-To enter the Service Mode, press the Signal and Delay Start Keys for 3 seconds or until the unit sends out beeping sounds.

Service Mode:

1.The washer must be on to go into the Service Mode.

2.The motor speed will be displayed when started (It displays 0 when the motor does not spin).

3.The present state of the machine will not be changed.

(i.e., the current cycle in progress will not be interrupted and only the display will change)

4.To exit Service Mode, press Signal and Delay Start Keys for 3 second again, or Power Key.If no key is operated during Service Mode for 5 minutes, the machine will return to normal user mode.

While a cycle is not running

Quick Spin Test Mode		Start/Pause		Hold Speed Mode

Dealy Start + Pre Wash for 3sec or after 10 minutes

Definition of Quick Spin Test Mode:

-Quick Spin Test Mode is to do Spin Check. (High RPM)

How to Enter:

-During Service Mode, press the Dealy Start and Pre Wash Keys for 3 seconds to enter Quick Spin Test Mode. (Same for all Frontier 2 models.)

-Cannot enter once the washing cycle has started.

Quick Spin Test Mode:

As it enters into the Quick Spin Test Mode, it starts spinning and reaches to its maximum RPM. Once the Spin speed reaches the maximum RPM, the speed drops immediately.

To hold Quick Spin Test Mode (entering Hold Speed Mode), press the Start/Pause button. If the Start/Pause button is pressed during Quick Spin Test Mode, it will stop accelerating and hold its spinning speed for 10 minutes before going back to Quick Spin Test Mode.

Also, to cancel the hold and allow Quick Spin Test Mode to continue, press the Dealy Start and Pre Wash Keys together for 3 seconds.

If you hold down the Dealy Start and Pre Wash keys for three (3) seconds when the washing machine is not in Hold Speed Mode, Quick Spin Mode is exited and Service Mode is restored.
