Read your manual for troubleshooting, advisories and required maintenance.
Tankless are maintenance heavy.
1L means tankless heat exchanger has lime build-up.
De-lime tankless unit.
U-tube has videos for de-liming tankless, but there is more to consider:
De-liming is yearly maintenance requirement.
Tankless are prone to lime build-up
Regular de-liming will not restore full efficiency to tankless unit.
Tankless cannot be exposed to water with more than 11 grains hardness.
Temperatures over 135 can cause minerals in water to harden on metal surfaces of any water heater.
Also clean Tankless water filter each month, and clean and maintain burner and combustion chamber yearly.
The cost of maintenance and cost of expected repairs and cost of parts plus cost of original installation will never pay back the $1-8 monthly savings on gas bill. All costs are energy.
