If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty flow meter in inlet assembly, Blocked inlet path, Wiring issue to flow sensor, Control board misreading pulses

How to Fix / Troubleshooting

Safety first: Disconnect power and close the water supply tap.

Check inlet filters and hose: Clean the inlet mesh filter and ensure the hose is not kinked, as restricted flow can confuse the flow meter.
Inspect wiring: Access the base and locate the flow meter (often integrated with the inlet valve or water distribution system). Check its connector and wiring for damage.

If cleaning and wiring checks do not resolve iF1, the flow meter assembly or inlet valve with integrated sensor will likely need replacement by a technician.
