What does Rinnai 11 mean?

No ignition: the heater is not turning on.

Call a pro: jump to when to call a pro Equipment type: tankless water heater
How it shows: Diagnostic code 11 on a Rinnai N-series SENSEI tankless water heater with pump (RUR199i, RUR160i, RUR199e, RUR160e).

Rinnai code 11 in the N-series with-pump manual is no ignition: the heater is not turning on. The owner lines are gas on at the heater, meter or cylinder, and gas in a propane tank. Code 12 is no flame and repeats the gas checks, then hands the flame rod to a technician. Code 10 is an air-supply or exhaust blockage, or a full condensate trap.

Likely causes

  • Gas shut off at the water heater, the meter, or the propane cylinder
  • Propane tank empty

Safe checks for 11

  1. Check that the gas is turned on at the water heater, the meter, or the cylinder
  2. If the system is propane, make sure there is gas in the tank
  3. If other gas appliances in the house will not light either, call the gas supplier from outside
Safety firstIf you smell gas, do not try to light the water heater, do not touch an electrical switch, and do not use a phone in the building. Leave and call your gas supplier from outside. Turn off power at the breaker and shut the gas supply before any panel comes off. Gas pressure, the burner, the gas valve, venting and the control board belong to a licensed technician or the manufacturer's technical support.

Capacitors can hold a charge after the power is off. Safety terms.

When to call a pro

If the gas is on and code 11 remains, stop. Rinnai's remaining checks (inlet gas pressure, bleeding air from the gas line, the PC board ground, the flame rod, the igniter, the gas solenoid valves and the orifice) are marked for a qualified professional.
