Rinnai N Series Replacement Water Flow Sensor (PN-403)
The water flow sensor on a Rinnai N Series water heater detects when water is flowing through the appliance and how much, triggering ignition and feeding the control board the data it needs to modulate the burner correctly. It's the component that tells the appliance a hot water demand has started in the first place.
This genuine Rinnai water flow sensor is made to the original specification, restoring accurate flow detection where the existing sensor has worn or become unreliable. Fitting the genuine part as part of servicing helps ensure the appliance ignites promptly and modulates correctly in response to actual demand.
⚠ Important: Installation and servicing must be carried out by a qualified technician familiar with Rinnai products. Turn off the gas supply and disconnect power before beginning any servicing.

Common Problems This Part Will Fix
Appliance Fails to Ignite on Demand: Restores accurate flow detection triggering ignition.
Delayed Response to Hot Water Demand: Fixes lag caused by an unreliable flow reading.
Intermittent Ignition Faults: Replaces a worn sensor commonly linked to unreliable start-up.
Why Buy This Product?
An appliance that hesitates to ignite or modulates inconsistently often has an unreliable flow sensor at the root of it, since it's the component telling the control board demand has started at all. Fitting the genuine sensor restores that detection to Rinnai's original standard, addressing the actual trigger for ignition and modulation rather than a downstream symptom.
