Noritz symptoms we fix

  • Visible scale or white residue at the inlet filter
  • Error codes (ignition failure, flame loss, or combustion/vent related)
  • Water gets hot, then cold, then hot again
  • Fan runs but no ignition
  • Low flow at the tap
  • Unit beeps or displays a maintenance warning

Common Noritz fixes

Cleaning or replacing the flame rod, clearing vent blockages, fixing low gas pressure, cleaning the inlet water filter, and descaling the heat exchanger. On older non-condensing models, we also check the stainless vent for corrosion.

Chevy Chase homes: what we see

Tight mechanical spaces in older Chevy Chase homes are where compact Noritz units shine, but vent routing through old masonry takes planning.

Most Chevy Chase homes are on WSSC Water, which licenses plumbers in its service area and runs the cross-connection (backflow) program. Mineral buildup still happens over time, which is why flushing tanks and descaling tankless units pays off.

Repair vs. replace

A Noritz that's 15+ years old with a failing heat exchanger is usually a replacement candidate. Anything else — sensors, igniters, fans, circuit boards — is typically worth repairing. We'll lay out both options with prices.

New Noritz installs

Current condensing Noritz models (such as the EZ series, designed as a tank replacement) can often use your existing water and gas connections with minimal changes. We still verify gas line size and vent length before recommending one.

Frequently asked questions

Why is my tankless beeping?

Many models beep with an error or maintenance reminder. Check the display code and call us with it.

What does Noritz error code 11 mean?

It generally indicates an ignition failure — often gas supply, a dirty flame rod, or venting. We diagnose the root cause instead of just resetting it.

How often should I service my Noritz in Chevy Chase?

Annually, including descaling and a filter cleaning.

Is Noritz or Navien better?

Both are solid. The right choice depends on your gas line, venting options, and hot water demand. We install and service both.
