Call (888) 987-0567Tankless Trouble We See in Antelope
If you need tankless water heater repair in Antelope, CA, your problem is very likely listed here. Each symptom has only a handful of possible causes.

No-ignition code (11, E003, 111)
Clicking with no flame means something in the gas, ignition or vent path is off. We work through all three.

Dripping from the cabinet
Where the water comes from decides the bill: a valve or a joint is minor, a failed exchanger is not.

Air supply or exhaust fault
A venting code means the heater can't move air: a blocked cap, a bird or wasp nest, drifted snow or an overlong vent.
Whistling or rumbling
Mineral scale, a laboring fan or a gas regulator problem, all of which testing will reveal.
Same code after every reset
Resetting hides the symptom for a while. A recurring ignition or exhaust code needs a technician.
Cuts out partway through a shower
Flow has fallen under the firing minimum, usually from a plugged screen, aerator or shower valve cartridge, or a sensor reading low.
Not sure which of these it is? Describe the symptoms on the phone and we'll tell you what it most likely is.

Keep It Running or Replace It in Antelope?
For the vast majority of faults, repair is the answer. The math only tips toward a new heater when an out-of-warranty exchanger has failed, or when an electric model is close to the end of its shorter service life.
When you call (888) 987-0567, mention the make, the approximate age and what the heater is doing. If a repair isn't worth the money, we'll say so plainly.
