I had this problem while under warranty and repair service ordered replacement circuit board. They never returned my calls to install. So I did it myself. Left chiller unplugged after I plugged all connections in. Once plugged in all worked well. After a recent storm the power went out and now the E4 on the left hand side is back. Is there any way to prevent this from occurring? This is two times in less that 3 years.
Is there any other way to correct these error codes?
How much does a new circuit board cost from Avanti?
