20 Most Recent Bosch Nexxt WTMC 3300 Electric Dryer Questions & Answers

I just had the same problem, motor runs but no heat. I had a fun time figuring out how take the front panel off, hint the rubber seal comes off easily. It looks like mine tripped the resettable over heat sensor. So far so good.

Normally they are mounted in the exhaust pipe behind the rear cover.

Hello, Welcome to FixYa.

There are a couple of scenarios which may prevent the dryer from starting with Bosch, but with the most common there are two thermostat's/switches
which could be reset, plus a no reset hi-limit ( on the lint housing )... i.e. macmarkus_15.jpg ...which cannot be reset, but the hi-limit is the one related to heating...located on the heater housing and the other (emergency shut off/belt switch) is by the motor shown below.

To save time and back and forth dialog, I`ll mention the most likely and what to do about it.

**Unplug the dryer before attempting any repair tips suggested here please...safety first**

There is an auto shut off or emergency kill switch next to the motor I alluded to which will prevent it to start in the event it was tripped for whatever reason.
This is the most likely scenario in my opinion based on your post...but again it depends on your model.
This will require you to remove the back panel again though. Once you've remove the rear panel, It will look like this image below and all you need to do is push it to the right ( from the back )...


Since you`ve already taken the back of the dryer off before to gain access you should have no problem.

Either Scenario I alluded to will require the removal of that panel so let me know if you require further assistance to do this.

The other would be resetting the hi-limit cut out, You can see through the back vent opening when the vent tube is removed ( cannot be removed without removing rear panel the first time, but if attached a certain way can be done each time after ) and then by pushing the red button in...shown below.



Keep me posted how you make out or if anything is not clear or if your model is completely different...some have line fuses at the back.

Thanks for choosing FixYa and good luck.

Lint has built up around the internal components...you need to open it up and remove any evidence of lint.....check for burnt can
bles and or failing element..replace...but always disconnect electrics before anything!

Likely the "door closed" sensor. Dryers won't operate without the door being secured

You need to go through the top panel with the switches to access the bulb. First remove the screws that hold the top to the dryer. (There are a series of tabs with the screws.) Next, use a flat blade screw driver to push down and pull out the plastic tabs along top of the front panel. Pull the top of the front panel back. Now look for some plastic tubes. Stick a screw driver down into the machine and pry the tubes up at the bottom. Then you can access the light bulb and its socket.

I hope this helps.

Bosch in their manual suggests using a vacum with a narrow tip to go into the hole and remove the build up.

Looks like you may have an over heat problem. Look for a problem with your vent system and pipes. If its partially blocked you will trip the heater over temp thermostat.

Hi , it sounds as if your bearings on the shaft of the drum need replacing . The seals that protect the bearings will wear down through time and that leads to the ingress of moisture and starts the rusting of the ball bearings that will start to sound very noisy. One way to check is try and push the drum upwards while empty and let it go see if it clunks you should be able to feel it in your hand .

One thing I found out was if you use dryer sheets they clog the screen. Scrub the screen with soap and water, dry and replace.
