Hi,

Welcome to Justanswer … my name is ***** ***** I will help you today!

I am sorry to hear you are having trouble with your appliance.

Hopefully, we can get this resolved quickly.

E04 is fault in electronics usually caused due to clogged pump and/or faulty control board.

Try this:

You will have to unplug the appliance and pull it out.

Then tip it backwards by around 45 degrees so excess water drains off completely.

After this is done, check the drain hose where it connects to house drain and make sure it is not clogged.

Then clean the mesh filter from inside and make sure it is not blocked.

Reconnect everything and plug it back.

Select any program and see how it goes.

If the error appears again the control module will need replacement.

Please DO NOT ACCEPT the PHONE CALL request.

That is auto generated and not sent by me.

If you have any further questions, please do not hesitate to ask!
