1. Display screen will not turn on
✓
Confirm the power supply is properly connected at the rear of the machine and the base of the e-box.
✓
If power supply is properly connected, perform a power cycle by disconnecting the unit from the power
supply, wait 30 seconds, and reconnect power. If a power cycle does not fix the issue, replace the e-box
(refer to the Service & Maintenance manual P/N 10120).
2. Pump will not run
✓
Confirm the pump wire harness is properly connected to the side of the e-box.
✓
Confirm the system shows a minimum of 30 psi inlet pressure.
✓
If an audible beeping noise is heard from the e-box, perform a system restart (see page 27) . If a system
restart does not fix the issue, replace the e-box (refer to the Service & Maintenance manual P/N 10120).
3. Low inlet pressure
✓
Confirm inlet water supply has been restored.
✓
If pressure is present in the system and the inlet pressure sensor is reading 0 psi, replace the sensor.
4. Wi-Fi will not connect
✓
Ensure a strong Wi-Fi signal is present from the router. A range extender may be required in certain areas
where the signal may not be reliable.
5. TDS values are not changing
✓
TDS sensors require 90 seconds of continuous operation before providing a dynamic reading.
✓
If a TDS value is well outside the expected range (based on pre-installation water testing), replace the
sensor.
