- PCB
- Pressure switch
- Water valves

About This Quiz

This test is to be taken after reviewing all the assigned training modules.

2.

If the unit is off and you are still reading 120 volts at the water valves and the wash cycle is not selected, you should replace the ______.
- Pressure switch
- PCB
- Water valves
Correct Answer

A. PCB

Explanation

If the unit is off and you are still reading 120 volts at the water valves and the wash cycle is not selected, the most likely cause is a faulty PCB (printed circuit board). The PCB controls the electrical components of the unit, including the water valves. If it is malfunctioning, it can cause voltage to be sent to the water valves even when the unit is off and the wash cycle is not selected. Therefore, replacing the PCB should solve the issue.

If the unit will not power up but you read 5 vdc at pin 1 and 4, 6, 7 at the power control board, you should replace the _______.
- Display PCB
- Main PCB
- Both boards
Correct Answer

A. Display PCB

Explanation

If the unit is not powering up but there is a reading of 5 vdc at pin 1 and 4, 6, 7 on the power control board, the issue is most likely with the display PCB. This suggests that there is power reaching the power control board, but the display PCB is not functioning properly. Therefore, replacing the display PCB should solve the problem.

How do you get into diagnostic mode on Model# WT5070/WT4801?
- Press power button and special Use
- Press soil level and pause start
- Press soil level and special use
- Press spin speed, soil level and power button
- Both c and d
Correct Answer

A. Both c and d

Explanation

To get into diagnostic mode on Model# WT5070/WT4801, you can either press the soil level and special use buttons or press the spin speed, soil level, and power button together. Both options (c and d) will allow you to access the diagnostic mode.

What is the difference between de and DE?
- DE is draining error, de is lid error
- DE is door lid error, de is draining error
- None of the above
Correct Answer

A. DE is draining error, de is lid error

Explanation

The correct answer states that "DE" stands for draining error, while "de" stands for lid error. This suggests that the capitalization of the letters signifies different meanings in this context.

What would you replace if in the test mode the pressure switch frequency with an empty tub is displaying less than 33 or more than 67?
- PCB
- Hall sensor
- Pressure switch
Correct Answer

A. Pressure switch

Explanation

In the test mode, if the pressure switch frequency with an empty tub is displaying less than 33 or more than 67, the pressure switch should be replaced. The pressure switch is responsible for detecting the water level in the tub and controlling the water flow accordingly. If it is not functioning properly, it can lead to incorrect pressure readings and affect the overall performance of the appliance. Therefore, replacing the pressure switch would be the appropriate solution in this scenario.

When PE code does not occur during spin with a load or with the pressure switch wires are being moved or shaken, what should you replace ________?
- Pressure switch
- PCB
- Line filter
Correct Answer

A. PCB

Explanation

When PE code does not occur during spin with a load or with the pressure switch wires being moved or shaken, the most likely component that needs to be replaced is the PCB (Printed Circuit Board). The PCB is responsible for controlling various functions of the appliance, including the pressure switch. If the PE code is not occurring even when the pressure switch wires are being disturbed, it suggests that the issue lies with the PCB, which may be malfunctioning and not properly detecting the pressure switch signals. Replacing the PCB should resolve the problem.

What would you replace if "dl" code was displayed and the voltage reading at the lid switch was 0 volts between rd-wh wires when the door is locked?
- Lid switch
- PCB
- Wire harness
Correct Answer

A. PCB

Explanation

The correct answer is PCB. If the "dl" code is displayed and the voltage reading at the lid switch is 0 volts between the rd-wh wires when the door is locked, it suggests that there may be an issue with the PCB (printed circuit board). The PCB is responsible for controlling various functions of the appliance, including the lid switch. Therefore, replacing the PCB would be the appropriate solution in this scenario.
