20 Most Recent Bosch Nexxt 800 Dryer Questions & Answers

Are you sure you don't need a professional Dry Vent inspection and cleaning? If you are in the market for an Dryer Vent cleaning check out Dryer Vent Cleaning Dallas Tx.

it is possible . I suggest that you talk to a service repair shop to get details of how to to it if it can be done.

More than likely you fried the belt or the motor.

If you have a Tumble Dryer that is not heating up but the drum is turning ok, then the chances are the thermal overload cutout has tripped. Bosch dryers have a reset button but you will have to remove the heater cover panel to access it, you will find it just above the heating element (a black stat with small red button) simply press the red button and if it clicks you've fixed it. It also may be: If the dryer doesn't heat, but the drum turns, check the thermal fuse(s). The thermal fuse protects the dryer from overheating and helps to prevent fires. If the thermal fuse is blown, it will have to be replaced

look for a 3rd temp stat this may be in the door area just to the top right to replace it you will have to open the top of machine??

Hi,
There can be many reasons why your dryer will not turn...

see this causes and fix it. God bless youTimer The timer is normally not at fault when the dryer won't start. In many situations where timers are replaced they end up being returned. First, check all of the more common components in this troubleshooting guide before replacing the timer. If the dryer won't start, the cause is much more likely to be a thermal fuse or switch. The timer can not be tested, it must be replaced if it is defective. Main Control Board The main control board is normally not at fault when the dryer won't start. First, check all of the other components in this troubleshooting guide before replacing the main control board. The main control board can not be tested and must be replaced if it is defective. If there are obvious signs of burning or a shorted out component on the board, it should be replaced. Belt Switch If the dryer won't start, there might be a belt switch that has failed. This is not a common problem and most dryers do not have this switch. If the dryer has a belt switch, the switch shuts off power to the entire dryer if the belt breaks. It is possible that this switch has failed, even if the belt is not broken. It can be checked with an ohm meter or continuity checker. If the dryer works at all, even if all it does is hum, this is not the problem. Incoming Power Problem If the dryer won't start, check to certain there is electricity to the dryer. For a gas dryer, unplug the dryer from the wall and plug something else into the outlet to see if it's working. For an electric dryer, check the home circuit breaker or fuses. If they are working, check the outlet where the dryer plugs in with a volt meter. There should be between 208 and 240 volts. If there is power to the dryer, check the more common items in this troubleshooting guide. Thermal Cut Out Fuse Kit Most dryers have several temperature control devices such as a thermal fuse, thermal cut out, high limit fuse or high limit thermostat. Some manufacturers sell the thermal fuse and thermal cut out in a kit. These kits normally solve no-heat problems rather than when the dryer won't start. However, in some models, this kit will solve both problems. Even though this is not the most common part to fail if the dryer won't start, both can be checked using an ohm meter or continuity checker. If they have continuity they are good. If not, they should be replaced. Drive Belt On most dryers, if the drive belt breaks the motor can still be heard and it will still be blowing air out the exhaust tube, but the drum will not spin. However, in some dryers when the drive belt breaks the tension pulley arm trips a switch which shuts off power to the entire dryer. If the dryer won't start, check to see if the belt is broken. If it is, replace the belt and the dryer should be fine. If the belt is not broken, check the other components that can fail when the dryer won't start. Drive Motor The dryer drive motor turns the drum and the blower wheel to exhaust the air. If the dryer won't start the motor might be defective. Before replacing the motor, check the thermal fuse, start switch and door switch because all three are more likely the cause. If the dryer won't start and the dryer motor makes a humming noise there might be something caught in the blower wheel, or the drum might be binding. Try removing the belt from the motor and checking the blower wheel for obstructions. The dryer motor can't be tested easily. If the more common components have been checked and it seems the motor itself is defective, it will need to be replaced. It is not serviceable. Door Switch The door switch is located near the dryer door and is activated when the door is closed. If the door switch fails, the dryer won't start at all. Many types of door switch will make an audible click when they are activated. If the door switch makes a clicking sound when activated it is probably not defective. If it doesn't make a click, it can be checked with an ohm meter or continuity checker. The door switch is relatively easy to replace and is usually not very expensive. Start Switch The start switch is on the dryer control panel. Depending on the model, either press a button or turn a dial to start the dryer. If the start switch fails the dryer won't start or make any noise. Test the switch with an ohm meter or continuity checker. If the dryer hums when the start switch is activated, or if the motor runs only while activating the start switch, the motor might be defective or something might be binding the drum preventing it from turning freely. If the dryer start switch does not have continuity when it is activated, it will need to be replaced. Thermal Fuse The thermal fuse helps to prevent a dryer fire by shutting off power to the dryer if it overheats. If the dryer won't start check this fuse first. Test the thermal fuse with an ohm meter or continuity checker. This is the most common part to fail when the dryer won't start. Once the thermal fuse has blown, it has to be replaced. It can not be reset.

Hello, welcome to FixYa.

I'll start by saying your post indicates it is a Bosch dryer "nexxt800 dryer.breaker attached to heating element keeps tripping"

Just to be clear though, you said the heater has been changed with new hi-limit attached (that is how the Bosch elements usually come new) correct ? The one thing I'd suggest you try is to thoroughly clean the lint screen under hot water and mild soap or white vinegar and run a cycle (without any items in the drum) with the lint screen vent removed and report if it runs better. Initially it sounds like a venting problem...as it could be overheating due to poor airflow, so perhaps a blower wheel clogged, exhaust pipe clogged, or an obstructed lint screen from extended use of fabric softener or sheets could cause this as well. Thank you for choosing FixYa. I'll need to watch for your reply before moving forward.

Hi,
If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

Most Bosch appliance come with a minimum 2 year warranty from the manufacturer, before trying anything yourself please verify if it is still covered as you may invalidate your cover if you attempt a repair yourself..... that said if the limiter has been tripped there will be a reason... a. you are not letting the cycle finish, the last 10mins is a cooldown which the unit needs to do. b. the load going into the machine is far too wet, c. the outlet hose is kinked or blocked or d. you are running several loads straight one after another. I have put a link for the spare part placement on this post and I believe that the only resetable stat is item 405 on page four. this is accessed by removing the back panel (obviously isolate unit from mains before dismantling) and the limiter is on the side of the heater box at the bottom right, look at the unit from behind.
Hope this helps

it sounds as if your plug configuration is for 220 volts. that means that all wires are needed to operate the unit. white is the common and red and black are both power leads. in other words...the red lead provides 110 volts and the black provides 110 volts, and the white is the common for both circuits. and of course the ground is for curcuit safety
to change to a three prong plug the ground must be sacrificed but with shock risk. i suggest a seperate ground wire run to an adequate ground.
a typical three prong plug will mean that the two prongs closest to the edges are the two power leads and will use the red wire on one and black wire on the other.(doesn't matter which one goes on which prong)
the white will go to the center or usually odd shaped prong. be sure and be safe!
hope this helps.......................jay

Power cable may break or machine's power switch malfunction. I suggest to download following manual (it is of different model) and see section 4.1 (Fault Diagnosis) on page 13. It may help you. ManualsLib - Makes it easy to find manuals online!
