Ruud and Richmond Water Heater Troubleshooting

On this page (7 sections)

The Short Answer: Ruud and Richmond water heaters are made by Rheem, so they share Rheem’s designs, but each model has its own manual. When one stops making hot water, first find out whether it is gas or electric. On gas, check the pilot or the status light on the gas control. On electric, check the breaker. A leak needs its source found before anyone talks about replacement.

Who makes Ruud and Richmond

Both names belong to Rheem Manufacturing Company. Richmond’s website says its water heaters are manufactured by Rheem (opens in a new tab) and sells them mainly through Menards (opens in a new tab). The current Richmond catalog (opens in a new tab) states that Rheem owns the Richmond trademarks. Ruud (opens in a new tab) is also a Rheem brand. Its site directs buyers to independent dealers and contractors who sell and install it.

In practice, a Ruud or Richmond tank often closely matches a Rheem model built in the same years. Even so, the model number on your heater’s rating plate decides which manual, parts list and code table apply. Do not assume a code chart for one Rheem-family model fits another.

Start with the rating plate

The rating plate is the label on the side of the tank. Photograph it first. It tells you:

  • Fuel. Natural gas, propane (LP) or electric, plus the electric voltage and wattage.
  • Venting. An atmospheric gas heater has a metal draft hood on top. A power-vent heater has a fan on top and plugs into an outlet.
  • Model and serial number. You need these for the manual and for any warranty or service call. Rheem’s support pages (opens in a new tab) cover all three brands.

If the heater is a tankless or heat-pump unit rather than a standard tank, the checks on this page are the wrong ones. Ruud and Richmond tankless models display codes listed in each model’s manual. The codes in Richmond’s Essential Plus and Encore manuals, including 11, 12 and 29, are explained in Richmond tankless error codes. For how Rheem-family tankless codes are organized more generally, see Rheem tankless troubleshooting.

What the symptom points to

What you notice Likely area How urgent
Gas tank, no hot water, pilot out Pilot, thermocouple or thermopile, gas control Same day. Relight only by the label
Gas tank, status light flashing a pattern Fault stored by the gas control Same day. Record the pattern
Gas tank, no status light at all Pilot out, or the control has no power Same day
Power-vent tank, fan silent or a flash code Venting, fan, pressure switch or ignition Do not keep resetting. Call for service
Electric tank, no hot water Breaker, high-limit (ECO), element or thermostat Same day
Electric tank, lukewarm or runs out quickly One of two elements or thermostats Soon
Water on the floor Fittings, drain valve, relief valve or the tank Today. A wet tank shell means replacement
Gas smell or CO alarm Gas leak or combustion problem Emergency. Leave first

Gas Ruud or Richmond: what you can check safely

  • Gas supply. Make sure the gas shutoff valve next to the heater is open (handle in line with the pipe) and that other gas appliances work. On propane, confirm the tank is not empty.
  • The control knob. Check that the knob is not on OFF, PILOT or VACATION. Vacation mode keeps the pilot lit but holds the water barely warm.
  • The pilot. Look through the sight glass. If the pilot is out, relight only by following the lighting instructions printed on the heater’s label. If it goes out again within minutes or hours, stop relighting. That pattern usually points to a weak thermocouple or thermopile, a blocked flame-arrestor screen, or a failing control. Why a gas water heater won’t stay lit explains each of these.
  • The temperature setting. The marks on the dial are approximate. For Rheem heaters with the SIT (Delta) gas control, Rheem bulletin TB-1444 (opens in a new tab) says each setting can vary by about 10°F. Turning it up will not fix a pilot fault and raises the scald risk. The approximate temperature for each mark on Richmond’s gas controls is listed in Richmond water heater temperature settings.

Status lights on the gas control

Many current Rheem-family gas controls have a status light. The meaning of each flash pattern depends on which control is installed. It is printed on a label on the heater or in that model’s manual, so read your own label first. As an example of how one documented table reads, Rheem bulletin TB-1627 (opens in a new tab) covers Rheem PowerVent ESII heaters with the Honeywell electronic control:

Pattern (TB-1627 control only) Display code Meaning
Short flash every four seconds none Idle, no fault
Alternating bright and dim none Heating, no fault
Four flashes, pause 31 Thermal cutoff limit lockout
Six flashes then one, pause 11 Failed trial for ignition
Six flashes then five, pause 10 Hard lockout, manual reset required
Seven flashes, pause 47 Flammable vapor sensor lockout
Eight flashes then four, pause 93 Valve fault detected

That table belongs to that one Rheem power-vent control. A Ruud or Richmond power-vent model may use the same control, but confirm it on the heater’s label before you rely on it. Atmospheric tanks use different controls with their own patterns. For Richmond, the atmospheric STATUS-light chart and the power-vent flash charts from Richmond’s own manuals are in Richmond water heater blinking light codes. A flammable vapor sensor lockout is a reason to keep the heater off and have it inspected. Do not relight a heater after flammable vapors may have been near it.

Electric Ruud or Richmond: what you can check safely

  • Breaker. An electric tank usually runs on a double-pole breaker. If it has tripped, reset it once. If it trips again, leave it off. A breaker that will not hold means a short to be found, not a breaker to keep resetting.
  • Was the tank recently drained? An element powered while the tank was empty burns out within seconds. If power was on during a drain or before refilling, expect an element replacement.
  • How it behaves. No hot water at all usually means no power, a tripped high-limit (ECO), or a failed upper element or thermostat. Hot water that runs out quickly usually means the lower element or thermostat. If your model has a display or status light, look up its message in that model’s manual.

The ECO reset and the thermostats sit behind access covers over live wiring. Resetting the ECO, testing elements and replacing thermostats is technician work. If the ECO trips more than once, something made the water overheat. Resetting it again does not fix the cause. Why a Rheem water heater is not heating covers the same electric diagnosis in more detail.

Leaks: find the source first

Dry the area, then watch where water reappears. A. O. Smith’s guide to puddles around a water heater (opens in a new tab) explains the same distinctions, and they apply to any brand of tank.

  • Drain valve at the bottom front. A drip from the outlet or threads is a valve problem. It is a minor repair. See Rheem plastic drain valve leaking.
  • Relief (T&P) valve or its discharge pipe. This valve opens when pressure or temperature is too high. Never cap or plug it. Have a plumber check the house water pressure and the expansion tank.
  • Pipe connections on top. Fittings and flexible connectors can be repaired.
  • The tank itself. Water coming from under the jacket or from rusted seams, with every fitting dry, usually means the tank has failed. A leaking tank cannot be repaired and needs replacing.

If water has reached the burner area of a gas heater, turn the gas control to OFF and keep it off until a technician has checked it.

Frequently Asked Questions

Q: Can I use Rheem parts and manuals for my Ruud or Richmond? A: Often the hardware matches a Rheem model of the same type and era. Look up the manual and parts list by the model number on your rating plate anyway, because controls change between model lines and production years.

Q: My Richmond came from Menards. Who handles the warranty? A: Start with the warranty document that came with the heater. It lists the terms for that model and how to make a claim. Have the model and serial number from the rating plate and your proof of purchase ready. Richmond’s contact page (opens in a new tab) lists a technical service line (1-800-432-8373) and a customer service, warranty, parts and tankless support line (1-866-720-2076).

Q: Is there a Ruud or Richmond “reset button” I should press? A: On electric models, the ECO reset is behind an access cover over live wiring, so it is not an owner step. Leave it to a technician. On gas models, follow the lighting instructions on the heater’s label. A control that stays locked out, or a fault that keeps coming back, needs a technician to find the cause.

Before you call a technician

Write down

  • The heater. Photograph the rating plate: brand, full model number, serial number, and fuel. The serial number usually encodes the manufacture date.
  • The exact code. Photograph the display, or count the flashes and the pause between groups. Note whether the code returns after one reset.
  • The water. From a dry spot, note the highest wet point, whether it drips or flows, and whether it is hot. A photo of the top fittings, drain valve, and relief pipe helps.

Stop and get help if

  • Gas or rotten-egg smell, or a CO alarm: leave now and call the gas utility or 911 from outside. Do not use switches or try to find the source.
  • Water flowing, hot discharge, a wet electrical cover, or water near the burner: keep clear and shut the cold inlet only if it is safely reachable.
  • A breaker that trips again, or a scorched or melted smell: leave it off.
  • A burner bang, flames outside the burner area, soot, or a smell of exhaust: turn the heater off at its control and do not relight it.
  • Never cap the relief valve, bypass a safety switch, or open gas, electrical, or sealed combustion parts.
