Hello,
I just happened across this site and I'm hoping someone can point me in the right direction. I have a six-year-old Rheem PowerVent (42VP40F) gas water heater that stopped working a couple of months ago. I called Rheem and they supposedly diagnosed the problem as a faulty igniter assembly. A few hundred bucks later for the new part and install and it seemed to be working again...until it went out again a week later. Sometimes I can temporarily fix the problem by switching off the blower, unplugging it and plugging it back in and turning it on, but it doesn't seem to respond to even that now.
Below is some information on the error code and what the manual says; any help with recommendations would be greatly appreciated! The master plumber who installed the new igniter assembly didn't seem to follow any of the steps outlined in the troubleshooting manual (listed below), and I know very little about water heaters, so I'm at a loss. I am fine with paying a professional to fix the problem, but I want to make sure he/she is performing the right fix so this doesn't happen again. THANK YOU in advance for any information!
The PowerVent Thermostat Control valve is displaying this error code, if it makes sense:
▼ A B C
• O O X X O
In the troubleshooting guide, it says the following:
"The maximum number of ignition retries or recycles has
been reached and the system is in lockout. (This means
there was no flame rectification to the control to verify
main burner.)"
Troubleshooting steps:
"1. Check if the gas supply is off or too low to operate.
2. Check the flame sense rod to see that it is located properly and free from contamination. Reposition the
flame sense rod or lightly clean with an abrasive cloth. (See last page for positioning of flame rod.)
3. The Hot Surface Ignitor may not be positioned on the burner correctly. Reposition as necessary. (See last
page for proper positioning of hot surface igniter and flame probe)
4. Low voltage to the water heater. (Verify the hot surface ignitor glows by recycling power and looking thru
sight glass window. If you have a glowing ignitor, then your problem is probably fuel related.)
5. Thermal Release Device is damage or missing. No oxygen in combustion chamber.
6. Inadequate fresh air to support combustion inside combustion chamber.
7. Main burner supply tube is blocked, bent or restricted; burner orifice is blocked or restricted."
