What causes a high-pressure fault in Zodiac Z200 M5, and how to resolve it?

A high-pressure fault in your Zodiac Heat Pump can be caused by air and water emulsion entering the device; in this case, check the pool's hydraulic circuit. Increase flow using the bypass and ensure the pool filter isn't clogged. Wait for the temperature to fall. Check the flow controller, clean the water condenser, and close the bypass valve to increase the flow rate through the device.
