Are there any problems with an instant water heater?
Below are 5 common problems associated with an instant water heating system. Inadequate Hot Water. It is important that you get a heater that is commensurate to household water heating demands. If the heater is undersized, it is unlikely to supply adequate hot water. A faulty part in the heater may interfere with sufficient water heating.
Why does my hot water heater flash LEDs?
Some LED’s produce a quick flash as the dimming voltage changes. I’d be surprised if it was anything other than voltage drop. You might be able to change the LED drivers for something that tolerates the voltage drop. (You could condition the power on the LED circuit but that could cost a bunch.)
What to do if your water heater is overloaded?
Your water heater may struggle to supply the hot water needed or shut down altogether if it becomes overloaded. If this happens, you should reduce the demand for hot water by limiting simultaneous applications, and you may want to consider resetting your unit.

Check them and replace as necessary.
Where do I find the failure code on my tankless water heater?
As most of the newer advanced tankless water heaters utilize the self-diagnostic system and are equipped with the LCD display on the unit or remote controller, a numerical error code will display or flashing light. Here are the ignition failure codes found on some tankless brands:
Why is my Bosch water heater flashing an error code?
This is not an error code; it is a flashing status message that tells you to check; the wiring connection, gas pressure as it might be too low, voltage as it doesn’t meet the required 120 VAC, the unit that might not be properly grounded or the issue with the control board. The primary fan spins slowly when the water heater is working.
Some LED’s produce a quick flash as the dimming voltage changes. I’d be surprised if it was anything other than voltage drop. You might be able to change the LED drivers for something that tolerates the voltage drop. (You could condition the power on the LED circuit but that could cost a bunch.)
Where is the ignition on a on demand water heater?
On-demand means that there is no storage water tank; water is heated while passing through the heat exchanger. The heat exchanger is located in the combustion chamber, where the main gas burner with the ignition is also placed (below). The gas is coming from the gas supply through the gas line and gas valve.
