Often PC boards are damaged by power fluctuations, or when a unit is plugged in with an extension cord. Extension cords cause a voltage drop. When the voltage drops, the amperage (heat) increases and damages the PCB. It could also be from the original install. If the gas line is too small or there is not enough combustion (make up) air, the machine will keep trying to adjust but does not understand why the unit is not working well. Then it displays an error code. It is always important to check the combustion and heater settings. Combustion is nearly never adjusted by contractors. And gas companies make mistakes too.
It would be great if you could post a picture of the installation and the state you are located in. The sound is sometimes caused when the fuel to air mixture is to lean. If your fresh air pipe is too close to the exhaust it can suck in the exhaust and cause all sorts of problems with combustion. Also, if you are in cold climate and the fresh air pipe is not piped to the outside (on the same wall as the exhaust), you can damage the heat exchanger.
Question edited for correct spelling of maker 'Noen' to 'Moen'.
'Fix' as in it is leaking? Or tighten it down because it is wobbly, or something completely different?
Well, we can have a one on one seminar by the internet. I've been a pumpman for 20 years. I can share with you my experience (household pumps, suibmersible pumps, turbine pumps, gear pumps, piston pumps, dewatering pumps, mud pumps, trash pumps, mining pumps, solids handling pump, etc....) Just take your pick. Just send in your e-mail for assistance. God bless.
It is leaking due to a defective mechanical seal. It needs to be replaced. To replace it, is to take the pumpcase off by taking off the bolts that hold it. Then, take the impeller off to take the mechanical seal behind it. Put the replacement in, and reassemble the pump. Just get in touch with us by e-mail to get more assistance.
Move the lever or turn the knob. Check the stop tap under the sink. Make sure the faucet control knob or lever is tight, There is normally a removable cover that hides the screw..
Question edited for clarity, full 'make model (what it is)'.
This a Menards special. To remove handles, look for a small hole hidden from the front. They take a small Allen Key.
