Raypak Pool heater corroding pilot assemblies at alarming rate

It must be raining inside your heater. Either your water flow (gpm) gallons per minute is off, or your gas pressure could be off. If ether one of these is not proper, then you could have a high condensation possibility inside your heater and the combination of heat and moisture will rust out/corrode your pilot assembly's quick.

My heater is 1 year old and was used only 1 week last October and will not light at was used in a small cabin in Canada ..I brought it home to get fixed..someone told me they rust or corrode when...

Yes, lack of at least occasional use can cause a problem. Rusting is one of then, The other is spiders who like to build nest in the pilot and the burners.Cleaning the heater will involve removing the front of the heater cabinet, to access the pilot assembly and the burners. A shop vac with a brush attachment works well to clean the interior of the cabinet and the burner(s). Canned compressed air with a straw nozzle is great for blowing out the pilot tip and the Oxygen Depletion Sensor (ODS) which is part of the pilot. To help you understand more about cleaning the pilot and the ODS, I have included a link to a demonstration on how to do it.

I am also including a link on ODS troubleshooting.

A word of caution. If the unit has severe rust and corrosion, don't waste your time cleaning it. Buy a new heater and use it more often.

I hope this helps you solve the problem and thanks for choosing FixYa.

Have a Raypak RP2100. When I turn it on the pilot lights fine but after a few minutes (~30 minutes) the heater turns off and PLT is indicated on the control panel. If I recycle the power it lights fine and...

If your Raypack (mine is a 2100 but most have the same electronic ignition pilot) lights and runs for about 2-5 minutes an then shuts off, you need to clean the pilot sensor. The pilot sensor tells the unit the Burners are running. If the pilot sensor becomes corroded, carbon, etc. the unit will light but will shut off after a few minutes as it thinks the unit is not operating properly. The unit will try to re light, but fail, and then PLT will show on the main programming screen. To fix the probelm, shut off the unit power. Remove the pilot assembly which is located at the bottom right of the unit. There is one screw holding the pilot assembly in place. Gently remove the pilot assembly. There is a fork like probe sensor (not the one with ignition and gas feed) that needs to be cleaned. Take some rough sand paper and clean it thoroughly. Re insert pilot assembly and fire the unit. If this fails, clean the sensor again. Problem solved!

Water heater won't stay lit

Sounds like the thermocouple is bad , if , your holding the ignitor pressed long enough . Rating of 1 - 10 , this would be a 4-5 . Don't replace the pilot assembly , just the thermocouple .

Gas pool heater pilot will not stay lit

Depending on the make and model of your heater, the first thing I would check for is gas pressure. If it is sufficient, check the pilot assembly for corrosion and/or a damaged pilot tube. Sometimes replacing the entire pilot assembly is a sure fix and also replaces the pilot generator that degrades over time. A new pilot assembly takes care of a couple of problems by improving gas flow and millivolts generated. Also, the orifice inside the pilot assembly could be corroded or clogged.
