How To Reset Richmond Water Heater
Your Richmond water heater just stopped making hot water, and you need to fix it now. Learning how to reset a Richmond water heater is the fastest first step, because most no-hot-water cases trace back to a safety switch that tripped. The reset itself takes about two minutes and costs nothing.
You just need to know which model you have.
The tricky part is that gas and electric Richmond heaters use completely different reset systems. A gas model has a red button on the front gas valve. An electric model hides its high-limit reset button behind a metal access panel.
Manufacturer specifications indicate that safety limit trips near 180°F to stop overheating. Your fuel type decides which branch of this guide you follow.

Quick Answer
Find the red reset button. On gas models, it sits on the gas valve near the bottom. On electric models, it sits behind the upper access panel.
Press it once and release. If it trips again, stop and call a pro.
Know Your Heater: Gas or Electric
Before touching anything, confirm what you own. That takes about twenty seconds. Look at the front of the tank.
- Gas model: A metal valve box with a temperature dial and a small red button. A pilot light window sits below it.
- Electric model: One or two screw-on metal panels on the side. No gas valve, no vent pipe.
Gas models also divide into two groups. Older units use a standing pilot, meaning a small flame burns all the time. Newer units use electronic ignition, which sparks only when the burner needs to fire.
The reset button works the same on both, but relighting the pilot is different.
The rating plate on the front of the tank lists the model number, fuel type, and input rating. Write that down before searching for manuals. You can match your model to the right instructions through Richmond's official support documentation.
Richmond is a Rheem brand, so the gas valves and error codes follow the same system.
Decision Branch A: How to Reset a Gas Richmond Water Heater
Start by turning the gas control knob to Off and waiting five minutes. That clears any gas that might have collected. Then follow the branch that matches your model.
For electronic ignition models:
- Press the red reset button once and release.
- Wait about 30 seconds.
- The control board should spark and light the burner.
- Set the temperature dial back to your normal setting.
For standing pilot models:
- Switch the gas knob to Pilot.
- Press and hold the red button.
- Light the pilot through the small window.
- Keep holding the button for 30 seconds.
- Release and turn the knob to On.
This same action resets the safety limit and relights the pilot. After either process, wait 30 to 45 minutes for the tank to reheat.
If the pilot won't light or the red button won't click, you're looking at a bad thermocouple or a failing gas valve. A reset won't fix those. If you smell gas at any point, stop what you're doing.
Leave the house and call your gas utility or a licensed plumber.
Decision Branch B: How to Reset an Electric Richmond Water Heater
Turn off the breaker first. That is non-negotiable. The access panel hides live electrical connections, and touching the wrong terminal can shock you badly.

- Flip the breaker marked "water heater" to Off.
- Remove the upper access panel with a screwdriver.
- Fold back the fiberglass insulation to expose the thermostat.
- Press the red or black reset button on the thermostat face.
- Repeat the same process on the lower access panel if your model has one.
- Replace the panels and insulation.
- Turn the breaker back on and wait about 60 minutes.
The high-limit button sits right on the thermostat. Some models use a small plastic cover that flips up first. Press until you feel a click.
If the button does not click, the thermostat is bad. Pressing harder won't fix it.
What Those Flashing Lights or Error Codes Really Mean
Newer Richmond gas models use an electronic gas valve with a small LED window. Count the flashes. The pattern tells you exactly why the heater stopped.
| Flash pattern | Meaning | What to do |
|---|---|---|
| Solid or one flash every 3 seconds | Normal operation | Nothing |
| Rapid flashing (2-3 per second) | Safety lockout | Press reset once |
| 2 flashes, pause | Ignition failure | Check gas supply |
| 3 flashes, pause | Flame sense problem | Clean the flame sensor |
| 4 flashes, pause | Control board fault | Call a technician |
| 5 flashes, pause | High-limit switch open | Press reset or replace limit |
As of 2026, most Richmond models built after 2018 use this Rheem-style system. Older mechanical gas valves have no LED at all. If your valve has a plain red button and no light, follow the gas reset steps above.

One extra clue: if the LED is completely dark, check for power at the gas valve. A dark control board means an electrical problem upstream. A reset won't help that.
Mistakes That Make It Worse and Safety Rules
Most reset failures come down to simple mistakes. Avoid these.
- Pressing the reset button more than twice. The second trip means a real fault.
- Resetting without checking the pilot or gas supply.
- Opening an electric access panel before turning off the breaker.
- Ignoring a blocked flue or soot smell.
- Resetting a heater that is actively leaking.
Safety comes down to a few hard rules. If you smell gas, do not press anything. Leave the house and call your utility immediately.
If you see black soot around the draft hood or smell burning, shut off the gas and call a pro. That points to a blocked flue and possible carbon monoxide risk.
Call a licensed technician if the reset trips again after the tank heats up. That usually means a failed thermostat, a broken high-limit switch, or an element covered in sediment. Repeatedly resetting a real fault can damage the gas valve or control board.
That turns a cheap repair into an expensive one.
Still No Hot Water? Your Final Decision Guide
Use this if-then list to make the call.
| Situation | Next step |
|---|---|
| Reset holds and hot water returns | Done |
| Reset trips again once the tank heats | Replace thermostat or high-limit switch |
| Pilot won't stay lit | Replace thermocouple or gas valve |
| Electric heater gives warm but not hot | Lower element likely bad |
| Water leaking from the tank | Replace the water heater |
| Soot or burning smell | Shut off gas and call a plumber |
Before you call anyone, write down the model number and any error code. That saves time and gives the technician a real head start. If you still want to dig into your exact unit, the model number on the rating plate points you to the right manual.
Frequently Asked Questions
Can I press the reset button more than once?
Yes, but only twice. If the button trips again after a second reset, the safety switch is reacting to a real fault. Repeated pressing can damage the gas valve or control board.
Call a professional instead.
How long after resetting will I have hot water?
Most Richmond tanks recover in 30 to 60 minutes after a reset. Larger 50-gallon or 75-gallon tanks take closer to the full hour. Electric models often take 60 minutes because the lower heating element warms the tank slowly.
Why does the reset button keep popping out?
The high-limit switch trips again because the tank is overheating. Common causes include a failed thermostat, a blocked flue on gas models, or a bad upper element on electric models. Reset once, then call a plumber if it pops again.
Is it safe to reset my water heater myself?
Yes, for a single reset with the right precautions. Turn off the breaker for electric models, and check for gas smells before touching gas models. If you are unsure about anything, stop and call a licensed technician.
