If the dryer worked fine at the old house, I would suspect a wiring or grounding issue could be causing your symptoms.
Electronic controls often exhibit erratic behavior when not grounded properly.

Tip: To save you money, whenever an appliance is moved from 1 location to another, and an issue like this arises, do a thourough electrical and vent investigation before contacting a service provider.
A new dryer will sense a venting inadequacy and give an error code. Investigate your venting system thoroughly. Below are some helpful tips on investigating a vent inadequacy. Always consult your user’s manual before contacting a service provider.

Below are some tips that will aid you in investigating your vent issue.

  1. Do not rely on visual evidence; clean the vent from one end to the other. If possible, remove the entire vent tube and take outside to run water through it. Brushes of different lengths are available from parts suppliers if you cannot remove your venting.
  2. Do not rely on apparent airflow velocities. All dryers use different airflow velocities and minor obstructions are not readily observed optimally without utilizing an anemometer, (air pressure/speed gauge).
  3. Disconnect the dryer from the vent and run a load to eliminate, or suspect, the vent as the cause. If the dryer performs normally then the vent is the cause.
  4. Water can condense in a flexible vent tube and cause sagging. This needs to be eliminated by replacing the vent with rigid ducting if possible, or by bracing the tube. There are numerous venting accessories and options available to optimize the venting of a dryer.
  5. Dryer manufacturers use varying combinations of blower speeds, tumble revolutions, heat temperatures, and sensors to achieve a favorable result.
  6. Always remember that the shortest and straightest vent is the best vent.
  7. The lint filter could be coated with an invisible coating from using fabric sheets in the dryer. Hold the filter horizontally under running water and if the water beads up and does not filter through, replace the filter, and stop using fabric sheets. This same invisible film can also build up on sensor bars and cause drying issues.
  8. Animals, snow, shrubs, etc. have been noted to occasionally restrict the air from exhausting to the outside, by blocking the exterior vent cap. Be sure and check this frequently, especially on cold days, as animals love to be near a heat source.
If my assistance helped resolve this issue, please show your appreciation by rating how effective my advice was in resolving this issue.
Thank you,

Bosch 500 series new dryer has locked up. Key showing on panel, door opens, but you press every button and get the same beep.

Hi dear.
Regarding your information, I would say Child lock has been activated. I do not know what model or serial number of your dryer but you need to refer your machine's user manual or contact Bosch for deactivate child lock. I hope that helps. Thanks.

Bosch nexxt 500 series dryer producing intermittent gas smell when running. wife says the smell has even permeated the clothes a time or two, but I haven't noticed it. heat exchage box? if so, how hard...

A few things to check...

First, check that the dryer vent is not clogged. You'll have to go outside to check. If you are not sure of a clog, disconnect from inside and have your wife hold a flashlight by the vent, then go outside to see if you can see it. This will also cause laundry to dry slower than it used to (your wife may have a feeling if this is the case).

Second, make sure you don't have negative pressure in the house (large house fans are good for cooling but move too much air out so the dryer cannot vent its exhaust gasses well). You can check by opening an exterior door about an inch and check if it swings open with a gush of wind. Even houses without whole-house fans can do this if you have enough bathroom fans and furnace fans going.

Third, If it is a smell of natural gas, then you should call a service technician because the valve is not opening/closing correctly (or fast enough) if you have a pilot-less starter.

Our start button is flashing on our bosch nexxt series dryer, but when depressed it doesn't start the dryer. We have just moved it into a new home.

Here is what happened to our nexxt dryer. So this may be the problem with yours. Our dryer is about 6 years old. The start/stop button was not making contact with the mini-switch. Used some hot glue under the lever that makes contact with the mini-switch. Put it back together and works great again. Saved about $260 on new control panel. Removing the control panel was pretty easy for a DIYer.

Unplug the dryer.

Remove the four screws that hold the panel in place. They will be hidden under caps on the housing, Pull off the panel. Be careful because the wires will prevent you from pulling it entirely off but you can pull it from the right corner up and flip it on its back side to expose the back of the panel.

The white wire guard will have to be removed. The wire ties holding the wires to the guard will have to be removed by cutting the ties. Replacement wires ties can be purchased at any home improvement store. Remove the control panel by pushing the plastic clips in that hold it to the housing. There should be 6 and two plastic clips on the right center of the panel. If done right it will easily pull off. If force is needed one or more of the clips have not been disengaged. Do not force it because it is made of plastic and will break.

Once the control panel is removed from its housing, the start/stop button can be identified-last one either on the right or left (can

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.
