Not fireing up


Mark, It sounds like the gas valve may be bad. You may want a tech to diagnose and repair.There are other things to check also air intake and exhaust must not be plugged and the exhaust fan must be operational if equipped.
Check the attached links,instruction and guides, Good luck

Having problems with models sutting down. Relates to combustion shut off system. Explain how system works, with corrective action, especially draft system. Pilot ignites, burner operates for second or two...


As a general rule with Rheem gas water heaters, the manufacturer suggests calling trained service technician and their products do not have specific service bulletins.
I cannot explain combustion shut-off adequately. Post question on water heater forum.
http://www.thetankatwaterheaterrescue.com/forums/

Most likely the combustion and combustion parts need cleaning and maintenance, as a start point.
Gas water heaters today require yearly cleaning and maintenance.
That work would cover possible causes and combination of causes: from air in gas line, faulty venting, inadequate air supply, dirty parts, overheating, leaks, exposure to chemicals, corrosion, faulty gas control valve thermostat, sediment build-up.
You have a standing pilot light that is working, so gas supply sounds correct, and ECO is not tripped, so cleaning is major suspect right off.

Light a match under the vent hood and check if smoke drafts immediately upward.
Your water heater vent has a natural upward draft that pulls combustion by-product upward so the poison gas is vented outdoors to kill the world slowly instead of remaining inside the house. If vent is clogged, the air flow might not support combustion. Likewise if water heater does not have adequate incoming air supply, for example a tightly sealed house, then combustion is not supported. Also if you store bleach and pool chemicals and other assorted chemicals in trace amounts in same room or nearby, the burning chemicals will corrode combustion parts so they no longer perform.

The water heater red light keeps flashing rapidly on my Powervent 2 model 41VRP40N. It is not producing hot water and when I read the manual it says it needs more heat. What does this mean. How do I fix...


There are many things to check. The single most important test is for 24V at the gas valve after the ignitor is supposed tp be on. 19 V or less and there is either a bad ground or the ingition control board has failed. (Wire ground problems are a high probablilty)

Here is what the book says:

PROBLEM #1 - HOT SURFACE IGNITOR DOES NOT GLOW RED

(Remember to wait for purge time, 17/34 seconds, on models so equipped).

Possible causes

A. No main power

B. Faulty transformer

C. Faulty thermostat

D. Faulty limit switch

E. Faulty blower interlock switch

F. Faulty hot surface ignitor

G. Faulty ignition control

Solution

Step #1

Perform normal system checks of main power, transformer, thermostat, limit

switch, blower interlock switch, and replace faulty component.

Step #2

With power on and thermostat set at its highest position, check voltage

between "TH" and "TR" on HS780 ignition control. If 24 volts is not present

check output at transformer. If no, replace transformer. If transformer

checks out OK look at other controls in the 24 volt circuit I.E.: thermostat,

limit switch, blower interlock switch. Check for 120 volts between "neut"

(L2) and "120" (L1). Check for 120 volts at the ignitor across "IGN" and

"IGN" terminals on the HS780 ignition module. If 120 volts is present,
replace ignitor. If no, replace the 780 series module

PROBLEM #2 - IGNITOR GLOWS RED BUT MAIN BURNER

WOULDN'T LIGHT

Possible causes

A. Improper ignitor alignment

B. Faulty ignition control

C. Faulty gas valve

D. High inlet gas pressure

E. Polarity reversed

F. No earth ground

Solution

Step #1

Check for availability of gas at gas valve. Make sure the manual valve

upstream of the gas valve and the gas valve are in the full on position. Also

make sure gas is being supplied to the system at the proper pressure, too

high will lock-up the valve.

Step #2

Check proper polarity of "NEUT" and "120" on the ignition control by reversing

the wires, if reversed gas valve will not open. If this does not solve the

problem, replace wires as they were.

Step #3

Check for proper ignitor position.

Step #4

Check for a good earth ground by using a meter connected between L1

and furnace chassis. Should read 120 volts, if no, check and/or repair ignition
ground wire or ignition control mounting screws.
CAUTION POLARITY MUST BE OBSERVED

Step #5

Check for 24 volts at the gas valve terminals; "1" and "2" on a 7200 series,

"M" and "C" on a 7100 series, "TH" and "TR" on a 7000 series. If yes,

check wire integrity or change the gas valve. If no, change the 780 series
ignition module.

That is pretty much all of the troubleshooting required.

Thanks for choosing FixYa,

Electric heating not working


Make sure switch on water heater at back where electrical wire is attached is in the on position, as well as any breaker marked for water heater. Some RV's also share a connection at a switch by counter in kitchen that only allows either microwave, or water heater, not both at same time. Possible that ECO, Thermostat assy in behind black cover on outside may be faulty, but not very likely. If you verify that there is hydro to connection at back of tank, I would suspect element is faulty. Not uncommon to burn element out if it was on, before tank was full of water, or when tank was emptied for some reason.

The elbow is broken and the air from the hot water tank is leaked


Any exhaust air coming from the gas water heater is potentionally life threating. I would get it fixed. Do you have a CO2 meter close by the water heater? If it is leaking air back into the house that has CO2, after a certain amount the alarm will go off. If you dont have one get one. A must have with gas appliances.

What is error code 59 on a noritz tankless water heater lp?


The 59 code is typically caused by insufficient gas supply to the unit. It can also be caused by obstructed exhaust flow, stuck exhaust damper (located directly on top of the unit's exhaust), insufficient makeup air, or improperly installed venting (i.e. too long or too many elbows).

I would recommend initially checking the incoming gas pressure at the gas connection on the unit. The gas pressure should not drop below 5" water column for a natural gas unit, 8" for a propane system (the unit need to be operating at its maximum output).

Bosch 2700es natural gas unit keeps going out requiring a relight


Actually, this comment if coming from the math building at LSU!!!! How nice.

Any ways......You probably have a faulty thermo couple. It is the easiest and cheapest thing to do so try that. Most units have reverse threads so keep that in mind when removing. It is identified by a copper wire that leads to the main control unit. It should also be held in-place by some clips that just pinch the copper in place. Replacing the new one will be just the reverse of the removal.

Hope this helps

Water heater with electonic igniter will not work in power outage


What type of heater is this? I need to know the model name and make and then we can go threw the process of how to do it. Most gas heaters do not have power to them and I only know of a few tankless heaters that do.
