Hello and welcome to JustAnswer! This is James, I'm a Pool & Spa Engineer with over 20 years of experience, and I'll be assisting you today.

Sorry to hear your appliance is having issues, please stand by while I find the answer for you, this is not an immediate service however I will try and respond as soon as possible.

A E5 is a overheat fault often suggesting the pump has detected the water temp to have exceed 42 degrees.

This is often the result of a fault on the temp sensor.

Turn off power at the wall wait 5 min, and check if there is a thermal reset on the side of the pump, press this, and then turn the pump back on and where it errors stragiht away then a new sensor is required. Since the spa is only a few monhts old you should contact the retailer to arrange for a replacement
