Flow Sensor and Thermistor Repair in Menifee
Tankless heaters rely on 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 correct.

Condensing Tankless Repair in Menifee, CA
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.
No Hot Water Tankless Repair in Menifee
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Menifee will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for quick fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Tankless Descaling and Flushing in Menifee
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is a smart move for most homes on hard water.
Pilot Light & Ignition Repair in Menifee, CA
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Menifee, CA diagnoses issues with igniters, flame sensors and gas valves.
