A Navien tankless water heater has sporadic leaks and inconsistent hot water, and the homeowner cannot get the service company to respond after a cleaning that worsened the problem.
The service company did not resolve the issue and is unresponsive; the homeowner lacks the tools and knowledge to diagnose the flow sensor or other root causes.
