This error message is because the water tank is full. Just empty it out and put it back in and the AC will start to work again. If that doesn't work then I don't know what the problem is, but I just had the E4 error and did that and the problem was solved.

Here is the manual if you need it; although it doesn't list error codes - the FAQ section on the site says; "What should I do if my unit has an E-4 problem? The broken water tank flipper will directly cause the unit to not function and the E-4 message will appear on the display screen." Have a look and see if that looks like it is the problem, and if you could post back with a photo we may be able to help you fix it, else contact Soleus for parts; Hope this helps :)

E4 is an internal error - it is not repairable. It's usually associated with a low freon or a freon leak.

What is error code e4 on vision fitness t9350?

I have an HRT9450 that is showing an E4 error code - but when I run the auto calibration it doesn't seem to finish.

It runs up the speeds and back down but then stops without ever showing 'end'.

When i then take the safety key off and replace it the E4 error code shows again.

The treadmill was working fine until I moved it a foot and then the error code shows - meaning I'm suspecting a lose cable but I don't know where to start looking for it.

Any advice?

Disherwash is showing e4 what does it mean

The E4 error is not usually associated with newer dishwashers. Older Kenmore dishwashers with digital displays would show an E4 error when the selector switch pads/buttons were stuck. You need someone In to look at it im afraid

I have waves split air condition its cooling is good but some time in the display e4 is coming and that time my ac is not giving cold air what is this.tell me some one.


The e4 that displays on your air condition come up simply because there is an error during the operation of the system. E4 means Error 4 which is a code that is interpreted as low pressure switch.

E4 simply means there is low pressure switch, the pressure switch turns on automatically inside the air condition, so when you turn it on sometimes the switch jams and does not open so the air condition will be on but would not get cold because the switch jammed and it displays an error signal to let you know there is a problem in the system.

Take care
