Bosch Nexxt 500 Series Electric Dryer


I have owned a Bosch Nexxt Electric Dryer, model WTMC3321US, since 2007. It has been reliable but nothing outstanding. It needs to be aired out from time to time because it starts to smell. This is the first time I've had electrical problems. It won't give me a error code but will not start the drying process.

Dryer stop - timer advances to 0:00


The dryer starts fine. The timer advances 5 minutes...then jumps again as much as 45 min...them counts down after 3 minutes, then to 0:00. It will restart immediately just fine.

Bosch WTMC3321US dryer low heat, need front disassembly to clean lint


A great washer and dryer pair, pretty reliable, over 10 years old, now Bosch Appliances pulled out of US? Some service info is available, pretty accurate, Well engineered and built, in this Electronic's Engineers opinion! Main washer failure was a blown apart water pump, which glass or other object damaged it. No easy way to open/access the filter recess, because it is caked with lint. Looking for whole front panel disassembly method, to clean it to be safer. Also cleaning all ducting in 100% of the dryer exhaust path. Because drying s weaker lately. If it was an Element failure, likely some Error Codes would show. Instead I am going to use a clamp on AC Ammeter to verify something near the 22A rating, would mean the heating element is OK.

Current problem with Bosch Nexxt 500 electic dryer


Our Bosch Nexxt 5000 dryer has been great but now it makes a scraping/squeeqing noise. We think a small screw has gotten in between the rotating drum and its cage. How do we open the dryer, presumably from back to clear out the space between the drum and its cage?


Do you own this unit? Please describe repair issue you are having.

How long did you have this dryer for? What is the problem with it right now? What kind of diagnostics did you perform? Any earlier repairs?

Bosch Residential Dryer WTMC3321US Drum Capacity


Dryer Drum Capacity as per Manufacturer Specifications (in cubic feet):


We do not have the drum capacity for this model in our database yet but we can try to research it for you, please send us a message with your request.

Calculate Dryer Drum capacity


This is a geometric method to calculate drum capacity based on the cylinder volume formula. Unfortunately, the value could be as much as 25% off from the manufacturer stated capacity.

Why? Because a drum is not exactly a cylinder. The edge where bottom connected to the wall is not at 90 degree angle but smooth and rounded. The end of the drum is not clearly marked and the back is not always flat. Finally, there are baffles inside the drum used for tumbling clothes.

This method can be used as a crude estimate but we do not recommend using it for comparisson when shopping for a new dryer.

To determine your dryer drum capacity please take two simple measurements:

Dryer Drum Capacity Measurements

1. Use the ruler to measure the depth of the drum (indicated by the red line on the diagram)

2. Now find the distance accross the drum, the diameter (the green line on the diagram). Do not confuse the size of the the door opening with the size of the drum. In this case make the measurements INSIDE the drum.

Solution:

Dryer Drum Depth: in. Dryer Drum Diameter: in.

Answer:

The Bosch Residential Dryer WTMC3321US drum capacity is ... cubic feet.

Make sure to use the manufacturer's part number when ordering a replacement.
