Flow Sensor and Thermistor Repair in Kapolei

Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are accurate.

Emergency Tankless Repair in Kapolei

A tankless unit that leaks internally or shows a fault you cannot clear needs quick attention. We prioritize no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meanwhile.
