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

Assuming you have allready checked the operators manual, check again on page 19 for "Accoustic Signal".  To deactivate the signal select a program press two of the option buttons and hold until a short signal is emitted.  There you have it.

My Bosch washing machine is showing a key symbolt, is beeping and flashing shows O and will not let me start a new cycle.

Hi,
The "F16" on a Bosch indicates the door is open / unlocked. If it's happening during a wash it would suggest either a faulty door lock, faulty wiring or worse, a faulty main control board. The wash program should halt when this comes up but you should be able to restart it when the door is closed. As the cost of a new door interlock isn't overly expensive. The best way to fix this problem is to purchase a new lock and fit it.
Thank you !

Hello,

Welcome to FixYa.

Based on your description, "the door will not open. I have tried running the drain cycle and that doesn't work either" ...there is likely something obstructing your pump/filter hence the door cannot open.

With bosch as with most front-load machines, if the pump is blocked or the unit doesn't drain sufficiently, the door will not unlock.

Anyway, here`s the most likely way to remedy the non-drain and manually unlock the door issue.

**Unplug the washer from the wall or turn off the breaker before attempting any repairs**

Get some towels and if possible a wet/dry vac. If the machine drained, it won't be too bad. If your machine is stuck full of water, that sucks...hopefully you won't get too wet. ( maybe you`re lucky enough to be close to a floor drain )

1. Locate the round door on the front of the machine (about 6" in diameter, lower right corner)

2. Find a drill bit or small screwdriver that fits in the hole in the round door.


3. Insert the bit into the hole in the door. It will push in a tab, it doesn't take much force. Rotate the hole (clockwise) to 6'oclock and it should come free. (the edges are very sharp so be careful or wear chain-mail gloves).

4. Once the door is out of the way you'll be greeted by a 3-4" plastic cap with wings so you can unscrew it by hand. ( if it's too tight it can be turned by pliers...gently )




**DOOR RELEASE** you'll see a green ring attached to the pump, if you pull this the door should unlatch, but if the unit has water in it, getting it out first is usually a good plan )




5. There is a small collector lip at the bottom of the cap, that is where you can hold the wet/dry vac to catch the water. Unscrew slowly so you don't get flooded, until it is unscrewed all the way out.

6. Now pull out the trap and visually inspect the inside of the pump as well as the filter/trap.


7. After inspecting for any debris or obstruction`s re-install the button trap/lint filter and plug the washer in to power or reset the breaker and give it a test.

**Run a load and watch for leaks. Leave the pump access door off until you are sure you screwed the cap in tight and there are no leaks**

Ultimately you may have a faulty drain pump, but I would certainly start by performing the things I listed first.

Let me know if you require further assistance and if not and this solves your problem, please rate the solution I provided accordingly.

Thank you for coming to "fixya" and good luck.

Regards,

Macmarkus :)

The door locking mechanism has malfunctioned and/or is overheating. It is recommended that remove power from the appliance (unplug it) for 30 minutes and try again. If the problem persist, you will need to replace the door lock assembly.
