What Causes the E3 Error?

The E3 error on a Madimack heat pump is triggered when the flow switch fails to detect adequate water flow through the unit. This can be caused by a faulty flow switch, blocked filter, or low water pressure. If your filter and pump are operating correctly, replacing the flow switch is the recommended fix.

Installation

This is a direct replacement part. We recommend having a qualified pool technician install the flow switch if you are unsure. Ensure the heat pump is powered off before beginning any work.
