.. and no heat but I smell gas.

Is this an issue with the pilot light?

Does the blower run when starting?

Yes, it comes on.

I'll read your link. I've read in the manual (probably for a more recent model, mines 2003 era) that power cycling it could clear the issue and/or it might be the high limit sensor.

Now don't I feel STOOPID!

The way this was plumbed you have to step over the gas line (rigid pipe at least) to get to the Jandy Control Panel. Apparently I recently nudged the gas shut off valve to a half closed position so it was probably getting insufficient gas to ignite. At any rate, problem solved for now and something else for which to be on the watch.

Gas valve turned off a lot. And when I ask if the gas is on I always get an Of course reply. Check the gas line was going to be my next suggestion after the blower.

Probably need to consider moving or redoing the gas line if the valve is in a position like that where it can easily be bumped into.

Note: Normal boot up is 888, 128 and then rX where X is the software revision number.

The numbers are displayed briefly and then go to water temperature.

Anytime you want to come over and do that is good by me! In the meantime I'll just be aware of it.. This is the first time it has ever happened BTW.
