Question about Pentair Mastertemp Heater
I just opened the pool and have not turned on the heater at all. Today, when I turned on the pool there was a pool of water around the heater. I opened the panels on both sides and on the backside there was water coming out out the white round manifold where the gas comes in. It fills the chamber about 1/4 full and after I turn the pump off it recedes.

Water is coming out of where?
Are you saying that is coming out of the vent pipe that the exhaust gas comes out of or blows out of?
if so, you have ruptured the internal heat coil. Big job!

SOURCE: service light on
I just had the same problem resolved, my mastertemp 400 would run up the temp to 82F and then cutoff, the service light flashes and then 50 seconds later the heater would restart and run for 2 minnutesbefore shutting down again and relighting in 50 seconds. Repeating until the temp setting is reached.
I had the pool guy out 3 times until he found a bad thermal regulator valve (kit #77707-0010). Once replaced the heater runs great.
He told me that it's my pool chemestry that is to blame, I had it checked (like I do weekely by me and monthly by the pool supply store) and it perfect??? I'm now questioning what caused the corroson and stop it from coming back?
I hope tis helps.

Make sure the gas valve is set to on and thermostats are set properly. Check the pressure switch and high limits for continuity.Check wires for signs of damage, etc..

This sounds like you have a problem with your pilot. You can check this with a small mirror to see if their is a spark when you turn it on. If you have any soot build up on the pilot that will stop the spark and keep it from lighting also. If you have a short on your pilot wire this could be the problem also. I hope this helps, good luck.

This is a fan falure code. It can mean the fan has problems (not likley if the fan goes and isn't labored) You have a sensor in your exaust (probally not this if you don't get a good start) The culperet is probally in the negetive pressure sensor. This is a 2-3 inch disc with wires going to the controls and a rubber tube going to the fan. Pull the tube from the fan and make sure the fan fitting is clear (poke with a tooth pic) Be sure their are no kinks in the hose. If the heater is 4 years old the diaprahm could be bad in the pressure sensor. Check the other things first but this is probally your problem. Good luck, hope this helped.
