Some tankless problems are clear, like a leak. Others are harder to pin down, like water that goes lukewarm only when two showers run. This page walks through common symptoms so you can describe yours when you call (720) 710-1610.
If nothing happens when you open a hot tap, the unit may not be sensing enough flow, may have lost power, or may be locked out.
The unit may be trying to heat but cannot reach the set temperature. That can be a part, the gas supply, or more demand than it can handle.
Changing flow, a cycling heater, or a worn mixing valve can all cause this. Note whether it happens at one tap or all of them.
A clogged inlet screen, buildup inside the unit, or a problem at the faucet can all lower the flow.
A tankless heater still has to push hot water through your pipes. Long pipe runs mean a longer wait, and a recirculation pump can change that.
Colder water coming into the house in winter means the heater has to work harder, so you may get less hot water when several taps are open.
Repeated shutdowns are not normal. Ignition, overheating, venting, or electrical problems are common causes. Call instead of resetting it over and over.
If one of these sounds like your heater, call and describe it.
Note whether the display shows a code, whether the unit has power, and whether every tap is cold.
Running several taps at once can go past what the heater can handle. A pro can tell that apart from a real fault.
Note when it happens and how much water is running. That helps track down problems that only show up sometimes.
A shower valve or a clogged faucet can look like a heater problem. Try a few taps before you call.
