53PVN shuts off after a few minutes

My new 53PVN shuts down after a few minutes, with the error code C4 13. It is very well ventilated, nothing in front or on the sides. I am at 7000 feet but without a high-altitude chip. Could this possibly be the problem?

Rheem rtg-53pvn will not turn on and heat water when hot water is turned on - no error code - remote just goes off like the power is off


Before calling service technician, open following link for Rheem troubleshooting resources including Rheem chat:
Rheem will suggest you catch up on required yearly maintenance which would cover most causes for common error codes, and cover cause of no error code including plumbing problem or loose wire or PC board failure. Combination of problems can also cause failure and these issues would be covered by general maintenance.

Thermostat flashes IL ? Model PTG-53PVN

The Controller displays error code "1L."
There is a build-up of lime in your Paloma.
Contact your plumber to service the Paloma by flushing out the lime.
Also search u-tube for flushing lime out of tankless.

Just installed a reem rtg tankless unit fires up then shuts down and flashes c7 12 the until will work if I balance water valve way down


I am a free answerer, and I specialize in giving you resources for free
The paid answerers may have a person who knows your product and the error codes
The manual will also have the error codes.
The person who installed the unit will also know the error codes (or should know)
Each day I see 20-25 unanswered questions about tankless water heaters.
The number of questions shows the complexity of the machines, and the inability of the manufactures to take care of their customers.
The manufacturer will refer you to the installer.

The link above goes to Rheem tankless water heaters
Click on a product and it opens a page showing many tankless models
Click 'more information' and another page opens with spec sheets and other pdf
Not surprisingly there are no troubleshooting steps or troubleshooting flowcharts
There are plenty of ways to buy a tankless
There are not many ways a do-it-yourselfer can fix a tankless

How do I delete the stored error codes on my Rheem RTG-53PVN tankless water heater?


Some error codes cannot be reset...Example would be P/S failure on the PCB. Any other error, if you remove power for approx. 2 min - error should clear. - if not you need to contact Paloma/Rheem customer (800-432-8373) support
