My 6 month old, master temp 400, fires up for five seconds n shuts off. Does this cycle three times then stays off with service heater light (red) lit. Any ideas?

Could be an issue with gas

Could be an issue with gas pressure which should be at 4"-14" water column (static) with no more than a 2" drop when the gas valve opens, or could be an issue with the igniter? Please contact us at 1-800-831-7133 for further information on troubleshooting and warranty information.

I've replaced PC board. Panel

I've replaced PC board. Panel initializes with 888, 128, r13 and then goes dark. No blower no heat. Troubleshooted with Pentair via phone. Ran a bunch of diagnostics they said is was temp sensor. Replaced temp sensor. Nope. Same issue. Called Pentair again. Isolated remote control system. No difference. Tech said it must be the (new) PC board. Put in the old PC board - nothing. Blank screen. Ordered another new PC board ... getting expensive...
