My aircon gives me a E4 error. what does that mean? I need a manual urgently


Estelle, Estelle. Learn to use Google or some other search engine. That is what they are for. Lets try "aircon manual" but you probably need the model number, right?
So, using the information you gave, I got this:
Product documentation and of course it lists several models.
Don't EVER submit a question without Make and Model included, unless you want non-helpful answers.

Mitsubishi VCR Model HS-821V Ejects Video Cassette & gives an error code E4


Sometimes things like that are caused by the mode switch which will either need to be cleaned or replaced. It's worth looking inside for damage inside the unit. Pay close attention to plastic parts.

What is code E4


E4 means the overflow sensor has activated.

Under the washer is a pan - with a sensor. If it gets any sort of water - it activates.
You can remedy this issue by pulling out the dishwasher, and tilting it up to about a 45 degree angle to empty the catch pan.

This should solve your problem.


Thanks for using FixYa!!

I have e4 showing


E4 error indicate an abnormal water level which means too much inlet water (E5 also is refer at this fault).

I quote other comments/solution about this same error:
-----------------------------------------------------------------------------------------------------------------------------------------------------
I had the e4 error code and i took the outer panel off and inside behind the power button is a grey reservoir tank which measures the water that goes inside the dishwasher which actually got bunged up with **** and grease causing the floaty thing to get jammed and cause the e4 code to come on which means abnormal water level the top to the reservoir just unclips on both sides then just clean all the gooey stuff out and put it back together it worked for me.
-----------------------------------------------------------------------------------------------------------------------------------------------------

Good luck.

Highlander KYD-25/c Error E4 displayed


You want to look up Guangdong Chigo who are the manufacturers of this unit. They have a list of error codes/service manuals etc on their site.... From the PDF:
"1、Check whether the operation current and power of the unit is abnormal. 2、Check whether the speed and wind quantity of the fan is normal, otherwise replace the outdoor fan or capacitance 3、 Check whether the surface of the condenser is too dirty, and it should be cleaned when it is too dirty. 4、Check whether the unit is short of the refrigerant, add the refrigerant after leakage detection and repair welding. 5、 Check whether the sensor and electric control board is normal, otherwise replace the board."
