What are the four basic steps of a washer cycle?

Fill, wash, drain, spin

100

Front-load washers clean clothes using what main action?

Tumbling through water

100

What actually dries clothes in a dryer?

Airflow

100

If the drum turns but there is proper airflow, but my laundry is wet which function is missing?

Heat

100

What switch prevents a washer or dryer from running with the door open?

Door switch / door lock

200

Why do front-load washers require empty space in the drum?

Clothes must tumble to clean properly

200

Why won’t a front-load washer spin if water is still in the tub?

It must drain fully before spinning

200

What component moves air through the dryer?

Blower wheel

200

Which two dryer functions depend on the motor?

Motion and airflow

200

What safety device commonly blows due to restricted airflow in dryers?

Thermal fuse

300

: What type of detergent must be used in front-load washers?

HE DETERGENT 

300

A front-load washer fills but does not tumble. Name two things to check.

Door lock, motor control / harness

300

What voltage does an electric dryer heating element typically use?

240 volts

300

Which dryer function causes overheating when restricted?

Airflow

300

What sensor tells the control board how fast a washer motor is spinning?

Hall sensor / tach sensor

400

Why do modern washers rely heavily on control boards instead of timers?

They control speed, direction, and safety logic

400

What happens if a front-load washer loses motor speed feedback?

It will stop or refuse to spin

400

What gas dryer component must glow before gas is released?

Igniter

400

Which dryer function is most often misdiagnosed as a “no heat” problem?

Airflow

400

Why should a blown thermal fuse never be replaced without checking airflow?

It will fail again due to overheating

500

What are the three required dryer functions for clothes to dry?

Motion, heat, airflow

500

: A front-load washer starts tumbling then stops and beeps. What’s the most likely category of failure?

Motor control, communication, or safety shutdown

500

: A gas dryer heats once, then never heats again until it cools. What failed?

: Gas valve coils

500

Which function failing can cause both long dry times AND blown thermal fuses?

AirFlow 

500

What happens electrically when a door lock fails during spin?

Control blocks motor operation
