Question about Rheem M206A 206K BTU Pool and Spa Propane Gas Heater

1 Answer

My pool heater turns on, but cuts off after a few minutes saying "clean filter/strainer pool service" or something to that effect. I understand from my manual that this may mean that there is insufficient water flow through my heater. I have cleaned my filter, pump basket, strainer, etc., but the heater still won't stay on. Water is rushing normally through my skimmers and my pump pressure is normal. So I don't believe that there is insufficient flow through the heater. I am afraid that my heater might be dirty inside or something. Could this be the case? Sometimes the "fault code" is "IGN." I have tried cutting it off for a while then cutting it back on, but it does not work. Ideas? Can this be fixed without a service guy? Our pool party starts in one hour. Thank you.

SOURCE: Error code 13 (air flow) tankless H20 Rheem

Have 2 of these Rheem units in my house. Both had this same error code within 30 days of each other. And my neighbor has 2 units as well - and guess what - 2 months after mine stopped working because of the code - so did theirs. It is not something that can be fixed. It is a manufacturer's defect - and it looks like Rheem has yet another class action on their hands (like the one for the RTG - 74 PVN). They need to do a recall to repace these units.

SOURCE: pool pump shutting down -- heater?

Trying to get the TA correct before you kill the alge? Leslies diagnosis?
You probally just need to kill the alge before you do anything. Nevermind the TA for now and just add about ten gallons of liquid chlorine. The alge untill you kill it will plug the filter constantly. This will give you the code on the heater and will make the pump run very hot and will hurt the plumbing by shrinking it. This will stop water flo by letting air in also it will leak water at the pump discharge.
A lot of liquid will break the alge as it is unstable, but use a lot.Once you kill the most of the alge then add probally another four gallons and now brugh the whole thing real good. now you can start running again and start with all the stuff they will sell you to adjust the PH and TA. I hope this helps, and good luck.

SOURCE: clean filter/skimmer service error.

You have a low water pressure problem. Once you clean the baskets and filter you will need to check for plugged lines on your suction and for a clog in your impeller on your pump. If your pump basket is cracked the impeller is the place to start. Reach into the pump, with the basket out go through the hole in the back of the pump pot with some long nose pliers and feel for anything in there. If you can't pull it out with the pliers then break the pump down and see if you can clear it then and run a wire through the veins on the impeller. Then if it still has problems you may have to replace the pressure switch on the heater. This is seldom the problem, it is more of a warning to tell you of the other things that may be wrong.

SOURCE: My pool guy had turned off the remote feature of

The clock indicator means the firemans switch is open. If you are running the heater remotely and thru a time clock the time clock is still off. Turn all the equipment on including the timer and you should be able to put the heater into remote mode.

If you still have trouble, please comment with your actual model and serial number from inside the heater.

They are referring to the strainer basket inside the filtration pump, and the pool filter system itself. The indication is either this basket is full of debris or the pool filter is so dirty you do not have enough water flowing through the heater. A safety device in the heater is shutting down the heater to prevent damage. None of the parts you named are inside the heater.

Prs error code, clean strainer

Your not getting enough pressure to run the heater. So you need to clean the strainers and clean the filter. If you have a DE filter you may want to break it down and clean it. While your at this you should check your pressure switch and your by-pass valve.

What do you do about a service strainer notification on a rp2100 digital

Clean the strainer basket on your pump and clean your filter. If this does not help you will need to check your impeller expecally if your basket has any cracks in it. Also if you have a by-pass valve between the inlet and outlet pipes going to the heater that should be 80-90% closed. Hope this helps, good luck.

Raypack gas pool heater displays"clean filter/strainer" when I turn it on

There is not enough system pressure to close the heaters pressure switch so the heater will not fire. Assuming your pump is on and any valves in your pipes are set correctly it means something is restricing water flow too much and needs to be cleaned to fix your flow rate and allow the heater to fire.

Start at the skimmer(s) baskets and then the pump strainer basket and finally clean your filter. If sand, backwash it. If cartridge or DE clean according to your manufacturers direction. In some cases cleaning a cartridge filter will no longer satisfy heater pressure requirements meaning you will need to replace the element.
