Bosch dryer wtmc3300us/01 lint filter light

8 posts in this topic

I'm going out on this unit today. I have read a number of post about the reset buttons, moisture sensor, lint in duct.  My question is do I have to open unit up to access reset buttons? Any other info much appreciated!  Unit will not start when button is pushed

I have seen many of these that actually have a clean vent but the filter itself is so fine it gets restricted but you can't see it visibly. Test by running it under water, if the water pools you need to clean the filter by hand. I've had many customers purchase an extra filter so that they can still use the dryer while they clean the other filter.

The Lint Filter light automatically comes on when dryers finish cycles

to remind customers to clean lint filters. The light doesn’t indicate

any faults and isn’t connected to a sensor.

The reset button you're thinking about is a resettable thermostat on the heater which is accessed from the rear. It will not affect the dryer starting, it only affects the heat.

To enter/exit test program for WTMC dryers:

1. Rotate cycle selector knob to Off position.

2. Push and hold Start/Stop and Delicates buttons at the same time, then turn dryer on by rotating cycle selector knob either

direction -- keep holding Start/Stop and Delicates buttons until Start/Stop light flashes rapidly. Dryer is now in the test program.

3. When test program has been entered:

♦ Start/Stop light flashes rapidly.

♦ Select individual parts to test by rotating cycle selector knob.

♦ Once test has been selected, start test by pushing Start/Stop button. Start/Stop light will stay on continually while tests are

running. Push Start/Stop button again to end any test – rotating cycle selector knob stops all tests except Control

Elements test. Tests have finished once Start/Stop light flashes rapidly again.

♦ To exit test program, rotate cycle selector knob to Off position.
