E4 code

Back to List

I've had my Alorair Storm Extreme for just over two years and the E4 code won't go away.  How do I fix this?  Thanks.

Hi Peter,

Check if the water pump can pump water normally by pressing the drain button manually. If not, check if the internal wiring of the electrical box is loose; if not, the water pump is defective and must be replaced. If the water pump is pumping water normally, the float ball may be stuck. Please remove the water pump and try to clean the float ball.
