If the Flow and Low Temp lights are coming on immediately at startup, even though water flow and temperature are normal, that typically indicates an issue with the system’s internal sensors or how they’re reading conditions.
Before replacing anything, we’ll want to properly troubleshoot the unit to confirm the cause. This can include checking the flow switch, temperature sensor, wiring connections, and control module.
Please give our support team a call so we can walk through a few quick checks with you and determine whether a component needs to be replaced.
We’ll also need to review your system’s warranty at that time to confirm if any parts are still covered. Please have your model and serial number available when you call so we can locate your warranty and assist you as quickly as possible.
