Suburban Mfg 233237 Flow Sensor for IW60 Nautilus On-Demand Water Heater

The Suburban Manufacturing 233237 flow sensor is a genuine OEM replacement part designed specifically for the IW60 and IW60RL Nautilus on-demand tankless water heaters. This critical component monitors water flow through the system, triggering the water heater to activate when demand is detected.

Key Features:

• OEM replacement flow sensor for Suburban IW60 and IW60RL models
• Works with the water heater's 2-Stage Modulating Combustion System (MCS)
• Rated for minimum 0.5 GPM activation threshold
• Monitors inlet water flow to ensure proper heater operation
• Lightweight component at just 0.08 lbs
• Essential for proper on-demand hot water delivery

This flow sensor is a vital component of the Nautilus system's microprocessor-controlled operation, which monitors inlet water temperature and flow rate to automatically adjust propane input for consistent hot water delivery. If your IW60 water heater is experiencing intermittent operation, temperature fluctuations, or failure to ignite when water flow is detected, a faulty flow sensor may be the cause. Replacing this component can restore proper functionality to your RV's on-demand water heating system.
