Troubles with the water flow also cause the R13 error on the pool heater to appear. This usually happens when the water is restricted inside the exchanger chamber or the water pipes are clogged. Not only that, but an irregular flow of water also contributes to the issue.

How To Fix It

Examine the heater to make sure that the flow of water is not restricted in any way and clear the chamber of all the accumulated water.

Turn on the water valve and make sure that it is set to the right water pressure. Make sure that the water is flowing properly and without any trouble.

4. Temperature Settings

The Pentair error code R13 is often displayed due to an issue with the temperature settings. Sometimes, the temperature of the pool water is higher than the temperature set on the heater, which prevents the heater from working. The R13 error on the pool heater appears as the heater doesn’t work.
