Search for the switch that the cfover weight pushes down to indicate its closed. push down with finger and hold to ensure that the error is not presentr. If its no longer complaining stiuck something to the cover that allows the switch to be depressed. It is likely the rubber pad has come adrift

My Brother MFC-8680dn keeps giving me a "Print Unable 72" error message. Any ideas how to fix?


According to Brother Solution Center:

The machine may not work properly because of the condensation inside of the machine caused by a temperature differential between the inside and the outside of the machine.
To clear the error message please follow the steps below:
  1. Keep the machine's power on and open the front cover.

  2. Leave the front cover open for 30 minutes.

  3. Close the front cover.

  4. Turn off the machine's power switch and turn it on again.

Back cover open message although cover is closed


Open the top and back covers. If you see any jammed paper or
other item, gently pull it out, then close the covers. If the error message
remains, open and close the covers again. If the FAX/MFC cannot reset
itself and return to the date and time prompt, it will display MACHINE
ERROR XX. Please call Brother Customer Service
and tell them the Machine Error number at:
In USA:
1-800-284-4329
In Canada:
1-800-853-6660
In Montreal:
1-514-685-6464

E15 error message making a funny noise, is the a


E15 indicates the anti flood device in the base of the appliance has been activated.

Unplug the appliance.
Take the cover below the door off.
Take the insulation out of the way.
Remove any water in the base that is lifting the float.

Once removed, try the appliance again. Watch through the open inspection panel to see if the appliance is leaking.

If the float isn't up activating the switch then the switch, wiring or control board is faulty. Check the float and check the switch.

Your machine is still under warranty so you do need to be careful about what you do.

Trying to repair it on your own may invalidate the warranty.

Hope helps.

Hi, I have an LG 1412RD washer dryer. I received the DE error message so opened the front to access the door lock and plugged in the electric socket which seemed loose. Now I am getting the OE message...


http://www.lg.com/au/support/product/support-product-profile.jsp?customerModelCode=WD-1412RD&matchedModelCode=NOT_MATCHED&searchEngineModelCode=WD-1412RD&initialTab=documents&targetPage=support-product-profile#
Owners manual above. LG washing machine error code – OEThe LG error code OE simply means “the pump is blocked”. Presumably the water isn’t being emptied properly. As with all error codes it is possible that there is a cause other than the exact description in the error code explanation but basically this error means as far as the washing machine is concerned it thinks the water isn’t pumping out. A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain hose or somewhere else in the system etc.

X3480 cover open message


Ajkill is right, although his description isn`t very exact. Take off the complete scanner part: (back hinges first, then the blue arresting lever at the front), disconnect the flat band cable and the power supply for the scanner part and take off the complete scanner part. You´ll see a triangular part that goes in a slot of the dark grey cover which covers the rest. It should press againt a white lever which itself presses a little black switch sitting on the printed circuit board. If this white lever has fallen off the switch is always in "Cover open" position. To get it and reposition it (if it isn`t broken) you have to take off the dark grey cover which covers all the rest: take off the front screws and carefully lever out the sides with a small screw driver. Good luck with the repositioning, it is very fiddely and to see how and where it has to go you best use a magnifying glass!  But I could manage it and my printer is working now again. And good luck with fitting it all together again without breaking anything!

I've got the "cover open" error message all the time.


A couple of possibilities.
There are two types of interlock switches on those machines.
First step would be to look all around the machine for any cover that may be slightly ajar.
Then look for broken plastic tabs on those covers that may actuate a switch.
Also some of those switches are actuated by a magnet, and one of the magnets may have come off.
But there is one switch that is not being closed.
Just look carefully for the openings where the switches are located on the machine.
