Many times faults like this can be cured by Uplugging the washer from the mains power supply and leaving for 10mins. Also check all filters, drain and supply lines are clear and not kinked.

replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

2002 bmw 530i key does not (remotely) unlock doors or trunk but they work fine manually.


Unlock vehicle. Enter vehicle. Close driver's door. Switch ignition ON and OFF. Remove ignition key. Press and hold unlock button. Press lock button briefly 3 times within 10 seconds keeping unlock button depressed. Release unlock button. Some models: LED flashes slowly for 10 seconds. Some models: Central locking system locks and unlocks rapidly to indicate correct programming. Repeat above procedure if central locking system does not work and LED does not flash or LED flashes continuously.

AVR 684 was working normally then shut off with rapidly flashing red led. Have allowed to cool overnight, tried different power sources, disconnected speakers etc, etc. Any ideas?


The unit more than likely has a fault in the power supply or the output stage. Common switching power supply problems are the FETs used for switching fail or the PWM generator fails. Output circuits can be configured many different ways. The trend these days is to use integrated high power amplifiers for each channel instead of discrete push pull amplifier stages.

When power switch is turned on the Power light is rapidly flashing & the 4 Ethernet lights are flashing. The box is Actiontec GT704wg


I do not have a solution to the problem. However, I am having the same problem. This morning the Actiontec GT704WG power and ethernet lights were rapidly flashing. The modem was non-functional. I could not even connect to the modem through the browser to see if I could find a problem.

The problem lasted a couple of hours. Then all of a sudden the modem started working again. I won't be able to tell if the problem recurs until I restart the modem. And if the problem does occur again, I won't be able to connect to the internet.

LAN led light alway on and flashing


Reset the router:
While the router is powered on press and hold the reset button for 5-10 sec. Release the button and wait until the router boots up (1 min).

If this does not work then you can try this

Try setting it into recovery mode and loading firmware:

Unplug power cable from the router and press the reset button. While holding the reset button plug the power cable in. Continue holding the reset button untill you will see LEDs on the router flashing rapidly.

You should be able to log into the router - you will see a prompt to load firmware. The firmware is available on our WEB site: http://www.dlink.com.au/tech/

Note - suggest you d/l the firmware BEFORE you reset router
