Hot water heater won't light

I've finally diagnosed the problem with my suburban SW6D HWH. This is a DSI heater--gas only. The problem is that the igniter rarely works. I need to replace it, but can't find it listed as a separate part. On regular HWHs, it's an easy replacement, but it seems not to be available for Surburban heaters. Has anyone had the same problem--and solved it?

Have you checked and set the gap on the electrode? It should be 1/8th".

The electrode is part number 232258 and the module board is a 520741/521099 or 232391 or 520814. Maybe that will help you find the parts. The different part numbers are for different serial number units.

Amazon as well as other places have the electrodes and the control boards.

Thanks Bama--I had looked on Amazon using the word "igniter". Use "electrode" and it pops right up. I will try that first. I checked the gap and tath seems to be ok. Thanks again.
