Hi everyone. First post here. I have a Pentair Minimax NT 200 that is giving me fits. Late last season the fan started making noises and I started getting the E04 error. The fan was obviously bad so I replaced it. It worked most of the time, but I would get the occasional E04 error, which I thought was do to a bad seal that I put on when installing the new fan. I resealed everything this year and it worked when I first started it up, but now the E04 is back. When it turns on, the fan starts, then after 20-30 seconds it calls for gas but the gas doesn't light and it shuts off the gas. It does this a few times then the E04 comes back. I know it's getting gas because I can smell it but it won't ignite. I checked the tube from the blower to the flow switch and it's clear, and I cleaned out both connections. Now I figured it must be the igniter, so I replaced that. Still nothing. It's doing the same thing, fan turns on, calls for gas and no ignition, shuts off the gas and cycles through again.
I'm at my wits end. Any suggestions would be greatly appreciated.
