Questions and Answers

1.

How do you initiate the diagnostic mode?
- A.
  
  Press Start/ Pause button
- B.
  
  Press Spin Speed/ Water Temp
- C.
  
  Press Spin Speed/Soil Level/Power
Correct Answer
C. Press Spin Speed/Soil Level/Power

Explanation
To initiate the diagnostic mode, you need to press the Spin Speed/Soil Level/Power buttons. This combination of buttons triggers the diagnostic mode and allows you to access and troubleshoot any issues with the appliance.

Rate this question:
2.

Once in diagnostic mode and you press the Start/Pause button 3 times, what have you selected?
- A.
  
  Tumble clockwise
- B.
  
  Drain pump on
- C.
  
  High Speed Spin
Correct Answer
C. High Speed Spin

Explanation
When in diagnostic mode, pressing the Start/Pause button three times selects the "High Speed Spin" option. This means that when the cycle starts, the machine will spin at a high speed to remove excess water from the clothes.

3.

What will happen if an error code is showing on the display and you press the Start/Power button?
- A.
  
  Error code will reappear
- B.
  
  Error code disappears and goes into Pause status
- C.
  
  Error code PE will appear
Correct Answer
B. Error code disappears and goes into Pause status

Explanation
If an error code is showing on the display and you press the Start/Power button, the correct answer suggests that the error code will disappear and the device will go into Pause status. This means that pressing the Start/Power button will temporarily stop the device from displaying the error code and put it on hold until further action is taken.

Rate this question:
4.

Which error code denotes there is a Drain Error?
- A.
  
  DE
- B.
  
  PE
- C.
  
  OE
Correct Answer
C. OE

Explanation
The error code "OE" denotes a Drain Error. This means that there is a problem with the draining system of the device. It could be due to a clogged drain hose, a malfunctioning drain pump, or an issue with the drain filter. This error indicates that the water is not being properly drained from the appliance, which can lead to issues with the washing or drying cycle.

Rate this question:
5.

If error code IE is displayed and you are reading 120 volts on the water valves, what should you replace?
- A.
  
  PCB
- B.
  
  Wire harness
- C.
  
  Water valves
Correct Answer
C. Water valves

Explanation
If error code IE is displayed and you are reading 120 volts on the water valves, it indicates that there is an issue with the water valves. The fact that you are getting the correct voltage reading suggests that the problem lies with the valves themselves rather than the PCB or wire harness. Therefore, the appropriate action would be to replace the water valves.

Rate this question:
6.

If an error code is displayed, should you just replace the PCB?
- A.
  
  Yes
- B.
  
  No
Correct Answer
B. No

Explanation
The correct answer is "No" because simply replacing the PCB (Printed Circuit Board) is not the appropriate solution when an error code is displayed. Error codes indicate that there is a specific issue or malfunction in the system. Therefore, it is necessary to diagnose the problem and identify the root cause before deciding on the appropriate course of action. Simply replacing the PCB without understanding the underlying issue may not resolve the problem and could potentially lead to further complications.

Rate this question:
7.

If LE is displayed, what should you check before the PCB is condemned?
- A.
  
  All wires
- B.
  
  Rotor
- C.
  
  Stator
- D.
  
  Hall sensor
- E.
  
  All of the above
Correct Answer
E. All of the above

Explanation
Before condemning the PCB (printed circuit board), it is important to check all the components mentioned in the options: wires, rotor, stator, and Hall sensor. This is because any issue with these components can cause the LE error to be displayed. By checking all of the above, it helps to identify and potentially resolve the problem before concluding that the PCB is faulty.

Rate this question:
8.

If FE is displayed, how do you check water frequency?
- A.
  
  Check the air chamber
- B.
  
  Press Wash/Rinse & Delay Wash
- C.
  
  Replace the PBC
Correct Answer
B. Press Wash/Rinse & Delay Wash

Explanation
To check the water frequency when "FE" is displayed, you need to press the "Wash/Rinse" and "Delay Wash" buttons. This action will allow you to access the water frequency settings and make any necessary adjustments.

Rate this question:
9.

If the washer does not power up, which is a quick way to determine if you need to replace the PCB?
- A.
  
  Check if LED is off while the power in ON
- B.
  
  Check the wall outlet
- C.
  
  Check the noise filter
Correct Answer
A. Check if LED is off while the power in ON

Explanation
If the washer does not power up, checking if the LED is off while the power is on is a quick way to determine if you need to replace the PCB. If the LED is off, it indicates that there is no power reaching the PCB, which could be a sign of a faulty PCB that needs to be replaced.

Rate this question:
10.

If the washer does not power up, which is a quick way to determine if you need to replace the Display PWB assembly?
- A.
  
  By replacing the PCB
- B.
  
  By confirming that the LED is ON
Correct Answer
B. By confirming that the LED is ON

Explanation
To determine if you need to replace the Display PWB assembly when the washer does not power up, you can quickly check if the LED is ON. If the LED is not ON, it indicates that there is a problem with the Display PWB assembly and it needs to be replaced. The LED being ON is a clear indication that the assembly is functioning properly and the issue might lie elsewhere.
