At this point remove the top cover. Remove the Water Bottle and pour 300 ml of water into the
Water Bottle support. This will operate the Float Switch at the base of the dryer.
2. Refit the Water Bottle (if the Water Bottle is not replaced the test will fail at this point).
3. The dryer will pause until the Float Switch has moved to the full position.
The drain pump will turn on and the drum will rotate Clockwise for about 15 seconds - actual Time
depends on quantity of water in the base reservoir.
The water that was poured into the support (filling the pump) will be pumped into the water bottle.
If the pump is faulty or a there is a blockage in the hose or a pump wiring fault, the
Water container will not fill with water at this point, and the drum will continue to turn
for approx. 3 minutes, then the dryer beeps, pauses for 30 seconds, beeps 3 times
then the Test Ends.
Pause 5 seconds.
Step Phase: Heater Operation and Rear Thermistor Temperature Check
4. Drum Rotates Anti-Clockwise with the Heater On (both elements) until the Rear Thermistor
detects a temperature Rise, - the heater then turns OFF and the drum continues to rotate for a
short period.
Pause for 5 seconds.
If the Rear Thermistor, Thermostat or Heater is Open Circuit (both Elements) or
disconnected the Test Cycle will finish at this point - then the dryer beeps, pauses
for 30 seconds, beeps 3 times then the Test Ends.
