Tip & How-To about Miele W4840 Front Load Washer

My Miele washing machine is locked.

Recently I received many requests from users in troubles because they could not unlock their washing machine.

I decided to publish a tip illustrating the unlock procedure.

These instructions apply to most Miele front loading washing machines. They will work on all the W4800 series washers.
Instructions on how to set on and off your Miele’s child lock function are also contained in the user manual.

If you attempt to open the door while the Child Lock function is activated you will get the message "Machine locked" and the picture below on display:

If the door lock is locked during the wash cycle, press the pause button, and the door will open.

In order to deactivate the Child Lock:

  • Press and hold the "Heavy Soil" button until the display shows an unlocked pad lock picture and says Ready to Use (hold up to ten seconds, it should be less).

If you want to re-activate the Child Lock:

  • Press and hold the "Heavy Soil" again, until the display shows a locked pad lock picture and says Ready to Use .

The drum door cannot be opened, and the machine may stay locked if one of conditions below is occurring:

  1. The water temperature is more than 55°C (130°F).
  2. The water level is too high.
  3. The Child Lock function is activated.
  4. There is a fault.

If the washer is in one of the above conditions, you will get the machine locking even if child lock is off.

If the door is locked because of a fault, and there is water in the drum, the machine will also lock up.

In that case the door will open only after accessing the drain pump.
The pump service door is opened using a tool stored behind the dispenser drawer.

The tool must be used only after disconnecting power.

I think I will post a detailed procedure on how to fix a blocked drain pump on the next tip.

I hope this tip has helped you to fix your problem.

adobe illustrator cs2 request code


I want to mention that the activation server for the Adobe CS2 products were removed and hence the CS2 and previous version can not be activated now.

If you have purchased the Illustrator CS2 then you can contact Adobe support and then they would provide you an alternate to get the Illustrator CS 2 working.

not receiving cold water to the machines tub.. Does have cold water comming to the machine hose connection, but not to the tub

There is an electrically controlled valve (sometimes two separate) that mixes and controls the flow of water into the tub. These devices are junk even when new and just not very reliable. Fortunately, they don't cost much to replace either.
To see a breakdown illustration of your machine and the accompanying parts list, go to the link below and enter your model number:
Sears parts dept.
You can normally see locations of the various parts of your appliance and this can help you decide if you want to DIY or have it done by a pro.

i need trouble hsooting manuals for LG home appliances

It is not clear in which city you are residing. It would have been easier to give you the reference of the local LG dealer who could have helped you to get the required booklets. Anway, On the Internet go to the website of LG Pakistan www.lge.com/pk/support-here-to-help.jsp and get in touch with the customer representative. OR Ring up on toll free no 0-800-1-5454 and speak to the customer representative and give your requirement. OR Go to local LG dealer and request him if he can help you to get the manuals/user guides.
