Richmond Water Heater Has No Hot Water

The Short Answer: A cold Richmond is not one part. Electric: tripped double-pole, ECO, dead upper element, or a burned thermostat. Gas: pilot out, FVIR lockout, or a failed Rheem-family control. Lukewarm with a hot tank is a mixing valve or dip tube. Identify fuel, then test that path. Do not crank it to 140 F as a diagnosis.

Search Intent & The Real Problem

Showers died. The jacket says RICHMOND. Lowe’s tags confuse people into thinking this is a mystery factory. It is Rheem guts: same 4500 W elements, same Honeywell / Resideo FVIR gas controls, same Paloma-based tankless boards, same plastic drain that weeps. Sister no-heat map: Rheem not heating. Gas-valve LED: Richmond gas valve. Wholesale twin: Ruud troubleshooting. Do not paste a Bradford White ICON chart onto this LED. A puddle is Richmond leaking — shut it down first.

What other guides get wrong

They open with a brand history. That does not heat a shower. They mix the electric access-door LED with the gas-valve LED. They tell you to crank the setpoint to 140 F as a diagnosis. They reset a dry-fire code without filling the tank. And they treat every Lowe’s Richmond as a standing-pilot when the jacket says do not light with a match.

Step-by-Step Troubleshooting

Step 1: Name fuel, platform, and the actual complaint

• What to look for: Rating plate. Photo of the LED sticker inside the door or on the valve. That sticker wins. A green heartbeat with hot water is often normal — flashing green.
• Required tools: Rating plate, flashlight, phone camera, contact thermometer.

Step 2: Electric Richmond — breaker, fill, then the light

Common Rheem-family electric sticker (verify your door): 1 flash = normal, 2 = dry-fire, 3 = ECO / high-limit, 4 = lower element, 5 = upper element, 6–7 = thermostats. Count two full cycles. Five flashes decoded by brand: 5 flashes.

• What to look for: Both halves of the double-pole on (a handle in the middle is tripped). A breaker that will not reset is a short, not a setting. Tank full — open a hot faucet until it runs solid. A 2-flash after a drain is dry-fire. Wires lifted, power verified dead: a healthy 4500 W / 240 V element is ~18.8 A and reads ~12–13 Ω across the screws. Infinite = open. Any screw-to-tank continuity = grounded.
• Required tools: Breaker lock, non-contact tester, multimeter. No meter = hire it.

Red ECO on the upper thermostat: reset once after you know why it tripped. Daily clicks are keep resetting. Brown plastic is how thermostats burn up. Totally cold is the upper circuit. Short hot then cold is the lower.

Step 3: Gas Richmond — LED, igniter, FVIR — not a bigger tank

• What to look for: Appliance cock parallel to the pipe. Control not left on OFF or Vacation. Standing-pilot that will not hold: Rheem pilot / will not stay lit. Electronic: one trial through the port — spark or glow, then flame. No spark is lockout, no 120 V, or a dead electrode — not a match. Seven blue flashes is FVIR or a valve fault on many of these controls — Rheem 7-flash. Nine is a different count — Rheem 9-flash. Dark LED: Rheem no status light. Chamber / vapor language: chamber sensor.
• Required tools: Jacket lighting sticker. Eyes. No union wrenches. Do not purge fittings. Do not match-light a chamber the jacket forbids.

Thermocouple standing pilots: ~20–30 mV. Thermopile electronics: hundreds of millivolts. A $12 thermocouple on a millivolt Honeywell that wanted a pile is the classic wrong part. Manifold pressure is licensed: NG about 3.5–7 in. w.c. / LP about 10–11 in. w.c. — confirm the plate. Water in the burner tray: shut gas. That tank is scrap and a CO problem if you keep firing it — dripping on the burner.

Step 4: Tankless and hybrid Richmonds — different boards, same last name

• What to look for: Paloma-based Richmond / Rheem tankless throwing 11 is failed ignition, 12 is flame loss — tankless flashing 11, code 12. Photograph the code. Reset once. Do not keep cycling a flooded burner. Hybrids: filter, condensate, mode, then a compressor code — not an element ohm.
• Required tools: Phone photo of the display. Thermometer at the tank outlet vs the fixture.

Lukewarm with a hot tank outlet is a mixing valve or dip tube, not a bigger Richmond. Do not raise setpoint to 140 F to “test.” That scalds and hides the mixer.

Step 5: Sediment, drain valve, and a tank that is actually dead

• What to look for: Popping on recovery, rotten-egg flush water, a plastic drain leaking plus rusty jacket weep. A 6–12 year Lowe’s tank that is also leaking is a replacement, not an element. Status light with no heat after a storm: electric after outage, gas after outage.
• Required tools: Paper-towel test at the drain vs the shell.

Do not epoxy the shell. Do not energize an electric Richmond that leaked down onto an element.

When DIY Ends: Calling a Licensed Pro

Stop if you cannot prove 240 V dead, the ECO returns, an element is grounded, the thermostat is charcoal, the gas valve will not latch, the burner bangs, you smell gas, the T&P is streaming, or a tankless 11 comes back after one reset. You may lock the breaker, count flashes, fill the tank, ohm elements with power verified dead, and follow a standing-pilot sticker once. Gas-control replacement, FVIR burner service, hybrid sealed-system work, and any leaking shell are licensed. A Richmond that “isn’t heating” with a tripped ECO and water in the bucket is a fire wait — not a third reset.

Frequently Asked Questions

Q: Why does my Richmond water heater have no hot water? A: Electric: breaker, ECO, or an open element (~12–13 Ω is healthy at 4500 W / 240 V). Gas: pilot, igniter, FVIR lockout, or the control. Tankless: a two-digit ignition code. Count the LED on that machine. A wet jacket is a new tank.

Q: Is a Richmond the same as a Rheem water heater? A: Same factory family. Flash charts, gas valves, and tankless boards are shared with Rheem and Ruud. Use the sticker on your Richmond, not a Bradford White or AO Smith chart.

Q: How do I reset a Richmond water heater? A: Electric: breaker off, then the red ECO on the upper thermostat once after you know why it tripped. Gas: follow the jacket lighting sticker — there is often no ECO button. Photograph any LED or tankless code first.
