Description
What the WTG86403UC is and where it fits
A condensation dryer solves the problem that stops most people putting laundry where they want it. Instead of pushing hot wet air out through a duct, it cools the air, condenses the moisture out of it and reuses the warmth, which means there is no vent and no need for an exterior wall. Bosch’s 300 Series unit is 24 inches wide, with a cabinet listed at 23.58 by 23.58 by 33.14 inches, weighing 92.2 pounds, in white, with a right hinged door and ADA certification. Where it belongs is an interior closet, a bathroom, a kitchen cabinet run or an apartment where a vent is simply not possible, usually stacked with a compact washer such as the Electrolux ELFW4222AW.
Living with it day to day
Two published numbers make this listing more useful than most, and one of them is not flattering. Bosch gives a noise rating of 67 decibels. That is a real figure rather than a marketing phrase, and 67 decibels is loud enough to be conversational level noise: for comparison, one washer in this catalog publishes 45 decibels. A dryer in an open plan apartment at 67 decibels will be heard. Publishing it at all is to Bosch’s credit, and it is the sort of number a buyer should weigh rather than discover.
Fifteen dry cycles and four temperature settings is a generous control set for a compact machine. The other characteristic of condensation drying is that it runs at lower temperatures than a vented dryer, which is gentler on fabric but slower, and Bosch publishes no cycle times here. Capacity is given two ways, 4 cubic feet in the description and 4.4 in the specification table, and neither is large: a compact dryer takes a compact washer’s load, which is the arrangement the format assumes. The product description is also truncated mid word in this listing, breaking off at Energy Star Ce, so part of the feature list is simply missing. Vented alternatives at similar capacity include the GE GFD55ESSNWW, and combination machines such as the LG WM3555HWA take a third approach.
Controls and connected features
Bosch describes this as a smart, WiFi enabled dryer, and the listing does not enumerate what the app actually does, so the specifics should come from Bosch’s own documentation. On a dryer the functions worth having are a cycle end notification, since laundry left in a warm drum creases, and remote diagnostics that let a technician read a fault before attending.
What matters more is what runs without it. All fifteen cycles and the temperature selections are chosen on the machine and complete with no network involved, so losing the app or the platform costs notifications rather than the ability to dry clothes. That is the standard position for laundry appliances and it holds here. The door is right hinged and, unlike several machines in this catalog, is not described as reversible, which is a real constraint in a tight installation: the door will always open the same way, and the machine has to be positioned around that.
Running cost and upkeep
Bosch publishes the voltage as 240, and that figure should be read carefully because it is consequential. A 240 volt appliance in the North American market does not plug into an ordinary household outlet; it requires a dedicated 240 volt circuit with the appropriate receptacle, the same class of supply a conventional electric dryer needs. No amperage is published, so the installation manual is still required to size the circuit, and an electrician should confirm what exists in the laundry space before delivery. This is worth stressing because ventless is often assumed to mean plug and play, and here it does not: no duct is needed, but a proper dryer circuit still is.
The other question a condensation dryer raises is where the water goes, and this listing does not answer it. Condensed moisture has to be collected in a container that the owner empties after every load or two, or plumbed into a drain. That is the single biggest practical difference from a vented dryer and it should be established from the manual, because a household that does not want to empty a tank needs the drain option and the plumbing to go with it. Bosch states Energy Star certification but publishes no annual energy figure, so running cost cannot be calculated. Upkeep on a condensation machine is the lint filter every load plus periodic cleaning of the condenser unit, which collects fine lint and loses efficiency when it clogs; that second job is the one owners forget. There is no duct to clear, which removes the fire risk associated with vented machines. Other compact and ventless options sit across the dryers section, including the vented compact COSTWAY portable dryer.
Highlights
- No vent duct required, so it works in interior closets and cabinet runs.
- Bosch publishes both a 240 volt supply figure and a 67 decibel noise rating.
- Fifteen dry cycles and four temperature settings on a compact machine.
- Lower drying temperatures than a vented dryer, which is gentler on fabric.
- No duct means no duct fire risk and no periodic duct clearing.
- ADA certification and a compact 24 inch cabinet at 92.2 pounds.
Things To Consider
- 240 volts means a dedicated dryer circuit, so ventless does not mean plug in anywhere.
- No amperage is published, so the circuit still has to be sized from the manual.
- The listing does not say whether condensate is collected in a tank or plumbed to a drain.
- 67 decibels is loud enough to be noticed in an open plan home.
- Capacity is 4 cubic feet in the description and 4.4 in the specification table.
- The door is right hinged and is not described as reversible.
Who it is not for
Anyone assuming a ventless dryer avoids electrical work should stop here, because 240 volts means a dedicated circuit exactly as a vented electric dryer would. Households pairing this with a full size washer will find a compact drum too small. Anyone unwilling to empty a condensate container after most loads needs to confirm the drain option before buying. And anyone whose laundry sits next to a living space should weigh the published 67 decibel figure seriously, because it is unusually honest and unusually high.
