Ring 9922 Water Heater Not Heating? Try This First [2026]

Quick Fix Summary

Most Ring water heater Model 9922 issues resolve by restoring power and resetting the high-limit safety. Turn off power or gas, wait 60 seconds, then restore power and press the red high-limit reset behind the upper access panel. Also confirm the thermostat is set to 120 F and that Vacation or Eco modes are not limiting heat output.

Step-by-Step Troubleshooting

Use the steps below to diagnose no hot water, lukewarm water, error codes, leaks, or noisy operation on the Ring water heater Model 9922. Always verify the unit type (electric or gas) from the rating plate and follow all safety instructions.

Safety first

Turn off power at the breaker for electric models (typically a 240 V, 30 A double-pole breaker). For gas models, set the gas control to OFF and close the gas shutoff valve. Shut off the cold water supply and relieve pressure by lifting the T&P valve lever briefly. If you smell gas, hear arcing, or see water leaking from the tank body, stop and contact a licensed technician.

1. Confirm model, settings, and modes
   Why: Incorrect temperature settings or eco modes can mimic faults.
   How: Locate the rating plate on the side of the tank to confirm Model 9922 and fuel type. On the control, set the thermostat to 120 F to 125 F. Make sure Vacation mode is off and any Child Lock or Control Lock is disabled. If your 9922 has a digital display or companion app, note any error codes or alerts before making changes.
2. Power cycle and reset the high-limit (ECO)
   Why: The safety cutoff trips during overheat or dry-fire and disables heating.
   How: Turn the breaker OFF for 60 seconds (electric). For gas, turn the control to OFF and wait 5 minutes to clear gas, then back to ON/Pilot and relight per the manual. Remove the upper access panel and insulation on electric models and press the red reset button on the upper thermostat. Restore power/gas and test hot water after 30 to 60 minutes.
3. Verify electrical or gas supply
   Electric: Ensure the double-pole breaker is ON and not warm to the touch. Using a multimeter (only if qualified), confirm 240 VAC across L1-L2 at the heater junction box. You should read about 240 V line-to-line; line-to-ground should read ~120 V each leg. Loose lugs cause heat and intermittent outages.
   Gas: Confirm the gas shutoff valve is fully open and the flex connector is not kinked. Typical inlet pressure is 7 to 10 in. w.c. for natural gas, 11 to 14 in. w.c. for LP. A licensed tech should verify and adjust gas pressure and perform leak testing.
4. Inspect thermostats and wiring (electric)
   Why: Miswired or failed thermostats prevent upper/lower elements from cycling.
   How: With power OFF, remove upper and lower access panels. Check that push-on connectors are fully seated and not discolored. Ensure the upper thermostat firmly contacts the tank surface. If the heater only makes a small amount of hot water, the upper thermostat or element may be at fault. Replace thermostats in pairs if damage or pitting is seen.
5. Test heating elements (electric)
   Why: Burned-out or grounded elements cause no-heat or slow recovery.
   How: Power OFF and wires removed from the element, measure resistance across each element terminal. Typical 4500 W/240 V elements measure about 12 ohms (range ~10 to 16 ohms depending on wattage and supply). Infinite ohms indicates an open element; near 0 ohms to the tank indicates a ground fault. Also measure each terminal to tank; the reading should be open (OL). Replace any failed element with the same wattage listed on the rating plate.
6. Clean and test ignition components (gas)
   Why: Dirty flame sensors or weak thermocouples prevent the burner from staying lit.
   How: With gas OFF and cooled, remove the burner assembly. Gently clean the flame sensor with a fine abrasive pad. For standing pilot systems, a healthy thermocouple under flame should generate about 25 to 35 mV. Inspect the spark igniter gap (typically 1/8 inch) and wiring. Reassemble, check for gas leaks with a soap solution, then relight per directions.
7. Flush sediment to restore heating efficiency
   Why: Mineral buildup insulates elements and burner surfaces, causing lukewarm water and noise (popping or rumbling).
   How: Turn off power/gas. Connect a garden hose to the drain valve and run to a floor drain. Open the drain and a nearby hot faucet for air. Flush 3 to 5 gallons in rapid bursts by opening and closing the cold inlet to stir sediment. Continue until water runs mostly clear. Close the drain, refill fully, purge air at a hot tap, then restore power/gas.
8. Address temperature and pressure issues
   Why: Drips from the T&P valve signal thermal expansion or a failing valve.
   How: If dripping occurs only during heating, add or service a potable water expansion tank and set it to match house pressure (typically 50 to 60 psi). If the T&P leaks constantly, replace it with a 3/4 in., 150 psi, 210 F rated valve. Never cap a T&P discharge. Consider installing a mixing valve to deliver safe 120 F water while allowing higher tank setpoints for recovery.
9. Check sensors and harnesses if codes appear
   Why: Control boards monitor inlet/outlet temperature sensors (NTC), tank sensors, and draft/pressure switches (gas).
   How: Note exact error codes from the display or app and consult the Model 9922 manual. With power OFF, inspect harnesses for loose or corroded pins. Typical 10k NTC sensors read about 10 kOhm at 77 F (25 C) and change with temperature. Replace damaged sensors one at a time and clear codes.
10. Evaluate leaks and water quality
    Why: Persistent leaks or odors point to failing components or chemistry.
    How: Tighten or replace the drain valve if it weeps. Check dielectric nipples for corrosion. Rotten egg odor can be reduced by swapping to an aluminum-zinc anode rod. If water leaks from a welded seam or tank bottom, the glass lining has failed; plan for replacement. Any gas smell, repeated breaker trips, or scorch marks require immediate professional service.

Pro tip: Compare your unit's breaker size, wire gauge, element wattage, and gas type to the rating plate. Mismatches can cause chronic tripping, slow recovery, or code faults.
